Reader Marcia Hall just posted an excellent summary, "6 Reasons Your Child Refuses to Do Homework." I urge all parents of school-age children to read this.
Homework makes a critical contribution to effective learning. First, it imposes memory rehearsal soon after new learning is presented. This promotes consolidation into long-term memory. Second, homework causes students to think about new learning, and thinking itself is the best form of memory rehearsal.
Unfortunately, too many teachers make homework "drill and kill." To be most effective, homework should require students to think about the learning in new ways and contexts. For example, if they learn some history facts during the day, the homework needs to require them to make an application of those facts, such as relating it to lessons for today's world or evaluating the history to preceding events or those that followed later.
Another kind of homework that is useful is as preparation for what is going to be presented soon in class. This use of homework can help stimulate interest. In any case, it gives students some factual background that will help them get more out of what will be covered in class.
If you or the teachers disapprove of homework, please re-think your position. Homework of the right kind is a time-tested major contributor to learning.

What Happens to Aging Brain
Deterioration of the brain sneaks up on most of us. The
first clue might be hearing loss, especially in the higher frequencies. We may
be forced into bifocals, even trifocals. But the most serious signs of
deterioration occur in the brain.
As we age, our reflexes slow. We
walk and act slower. We even talk slower. Our memory starts to fail, especially
the short-term form of memory ability that is so crucial for learning new
things.
Brain-scan technology reveals aging
can cause the brain to shrink. Nerve tracts in the brain shrivel, making the
cerebrospinal fluid cavities larger and even leaving gaping holes in the brain.
Shriveling occurs in the neuron terminal branches that form the contact points
among neurons. People may lose 40% or more of dopamine neurons causing
Parkinson’s disease.
These are brutal truths. Whole
societies are being affected in major economic and social ways in countries
where the population is aging rapidly, such as Japan (23% over 65), Germany
(20.5%), Italy (20.4%), and the U.S. (13%). The countries that show that
fastest rate of change in population age, in order, are Iran, Vietnam, Mexico,
India, and South Korea. The obvious consequences are a shrinking labor force
and shifting of a nation’s wealth to health care.
The challenge for aging
individuals is to reduce the rate of their decline. This has created a growth
anti-aging industry focused on vitamins and supplements, fad diets, gym
facilities, mind training programs, and books like my books on memory. The good news is that these things can work,
if they are begun while people are in early middle age.
A likely cause of mental decline in
most people is diminished blow flow in small vessels that are easily plugged by
cholesterol and fats or ruptured by high blood pressure. These undetected
“mini-strokes” are probably quite common as we age, yet they cause cumulative,
progressive damage. Another source of damage is the lifetime cumulative effect
of oxidative free radicals that result from energy metabolism. The brain
consumes about 20% of all the body’s oxygen, even though it only ways about 3.5
pounds.
When brain cells do die or are
damaged for any reason, healthy neurons are assaulted by inflammatory chemicals,
like cytokines, that are released by the brain’s immune cell system. Brain
inflammation is commonly caused by infections such as colds and flu and by
diets deficient in anti-oxidants.
We now know brain function need
not decline with age, at least for people who stay healthy and mentally active.
By the way, research shows that a lifetime of vigorous learning helps prevent
or delay Alzheimer’s disease.
Level of education and lifetime of
intellectual stimulus of research seem to protect brain against aging. Here are some examples:
- Leo Tolstoy learned to
ride a bicycle at 67
- Queen Victoria began
learning Hindustani at 68
- Giuseppe Verdi was still
composing operas in his 80s
- Somerset Maugham wrote his
last book at 84
- Frank Lloyd Wright
designed his last building at 89
- In their 90s, Robert Frost
was writing poems and George Bernard Shaw was writing plays, Georgia
O’Keefe was painting pictures, and Pablo Casals was playing cello
- Oliver Wendell Holmes was
still dominating the Supreme Court until he retired at 91
- Linus Pauling was actively
publishing just before his death at age 93.
- Leopold Stokowski recorded 20 albums in his 90s and signed a six-year contract at 96.
Scientists are particularly noted
for being sharp and productive long into the late 80s and 90s. The National
Science Foundation reports that at age 69 more than 29% of scientists and
engineers with PhDs still work full time, compared to 13% of scientists with a
M.S. or B.S. degree. Marion Diamond, an active senior scientist at 75, published
data showing that brain cells can grow and learning can improve throughout
life.
Of course genes and luck have a
lot to do with how well one ages. Even so, gene expression is influenced by
things like exercise, diet, and mental activity. Two genes have already been
identified that become expressed as new memories are formed.
Too many seniors resign themselves
to the ravages of age. They will find,
however, large benefits from challenging themselves in new experiences and
competencies. Better yet, learning new things makes you feel good about
yourself, especially when accomplishing things other people think you can’t do.

Memory Schemas: the Under-used Approach to Improving Education
I just attended a “memory schema” symposium at the annual
meeting of the Society of Neuroscience. The “schema” idea is that memory of
prior learning provides a framework or context for new learning. That is, new
information is evaluated for relevance to preexisting schema, which may
influence how readily new information transfers into memory.
The notion of schema stems originally from Harry Harlow’s
ideas back in the 1940s. Harlow showed that when a monkey learns a new kind of
problem, he solves it by slow plodding trial and error. However, if he has
experience with a large number of problems of a similar type or class, the
trial and error is replaced by a process in which the individual problems are
eventually solved insightfully. For example, if you learn how to do task A, B,
and C, when presented with a new task D, you might say to yourself, “I don’t
know how to do this task D, but it is like task B, and I do know how to do
that!” Thus, you have a leg up on learning how to do task D. The idea underlies
how people become experts in a given field: their accumulated learning of
various tasks provides them with a repertoire of what Harlow called “learning
sets” that makes it easier to learn new things.
Few of the speakers or audience discussants seemed to be
aware of this literature, and their ideas weren’t really all that new, except
that the focus is now shifting to memory instead of insight. The basic idea of
memory schemas is that associations among learning objects profoundly affect
how easily and well a person can remember. Certainly, memory is promoted when
learning objects are congruent, that is, have meaningful relationships.
Sometimes, however, you can easily remember incongruent items because they are
so different. These ideas are important to education, and in the panel
discussion at the end of the symposium, speakers were asked to address this
matter. But nobody did. And in school systems, few educators do either.
Master teachers have always known intuitively to structure
meaningful relationships among learning objects. In principle, this is done by
creating associations of word pairs, concepts, spatial locations, and assorted
rules and principles. All these things make it easier for students to learn.
The problem is that we educators don’t devote enough thought about practical
ways to create structured relationships that will promote memory formation and
recall. I don’t follow much of the educational research literature, but I suspect
that very little of it focuses on the best way to organize the presentation of
learning materials. For instance, has anybody conducted an experiment that
tests how well students learn the central concepts in the U.S. constitution and
its amendments, depending on how the concepts are presented? Or what’s the best
way to structure learning objects in the teaching of cell organelles and their
functions? Typically, in the latter case for example, a biology teacher
considers each organelle in turn and spews out information on what it does.
That may not be the most memorizable way to present the information. Maybe it
would be better to begin with the biological needs of the cell, how those needs
relate to each other, and then how various organelles fulfill those needs. In
fact, I took that kind of approach in the on-line biology curriculum I wrote, but no experiment has
compared the ease of learning this way versus the traditional approach. I do
know from my own experience with trying to learn a little Spanish that the ease
of memorizing verb conjugations was greatly affected by how I laid out the
words in a table.
To return the schema symposium, the experiments reported
made it clear that structured relationships of learning objects improve all
aspects of learning: encoding, memory consolidation, and recall. The time has
come to develop teaching strategies that exploit the brain’s preferred mode of
operation.
One example is the development of a PowerPoint method I
developed to create a one-flash card of learning objects that consists of
mnemonic icons systematically placed in specified spatial locations. The images
represent concepts to memorize, and the spatial locations create spatial
relationships that promote memory of the learning objects. For details, see my e-book for students.
In more general terms, the primary task of teachers and
students is to develop strategies to enrich the formation of memory schemas.
This means finding ways to increase the number and congruence of associations
among facts and concepts being taught. The research shows that major benefits
can be expected.

Behavioral Therapy Erases Bad Memories: Timing Matters
It has taken 50 years, but memory research has finally put
it all together to provide practical guidance to reduce forgetting of what we
need to remember and promote forgetting of useless or disturbing memories.
I have blogged before about animal studies showing that bad
memories can be erased. Bad memories are often created like conditioned
reflexes in Pavlov’s dogs. That is, the situational context in which bad things
occur act as associational cues that help cement the memory. If the cues are
repeatedly present but the bad event is not, the learned associated tends to go
away.
But in both animals and humans, this
“extinction” as it is called is not really permanent and the bad memories can recur.
Memory researchers have recently
discovered that when a memory is recalled, whether good or bad, there is a
short time where it can be modified by new thought or experience, and then it
is put back in storage (called “reconsolidation”). When this phenomenon was
discovered, it raised the possibility that timing of extinction trials might
influence effectiveness of treatments for anxiety. That is, better treatment
results might occur if extinction is attempted during the vulnerable
reconsolidation stage. In 2009, Joseph LeDoux and his colleagues demonstrated
in rodents that timing of extinction trials did in fact influence the erasure
of fear memory.
This modifiable stage provides a
way to treat even really bad memories, like post-traumatic stress disorder.
When a soldier, for example, recalls a bomb killing a buddy, that terrible
memory is subject to modification before it is re-stored. A typical modern
treatment for PTSD is to inject an anxiety-reducing drug just before the bad
memory is triggered that interferes with reconsolidation of memory. This
process may have to be repeated many times before the bad memory is finally
gone. Now a new study from the Uppsala University in Sweden has shown that bad
memories can be erased without drug.
Investigators created bad
memories in human volunteers by giving them an electric shock each time a
certain picture was flashed on a computer screen. They repeated this experience
16 times to establish a conditioned fear response. The next day after such
training, the subjects were brought back into the test room, and the fear-of-shock
memory re-triggered by showing the picture that had been associated with shock.
This was repeated eight times without associated shock, as a way to produce
extinction. Half of the subjects received their extinction treatments at 10
minutes later in which the fearful stimulus was repeated without any shock. The
other half of the subjects were given the same extinction treatment but delayed
six hours, when it was presumably too late to interfere with reconsolidation.
To measure the amount of fear
evoked by later presentations of the picture, investigators objectively measured
the amount of fear, using a skin conductance test that measured essentially how
sweaty the palms were. Signs of fear were absent in the group given extinction
trials at 10 minutes when reconsolidation was still in progress. But signs of
fear persisted in the six-hour group.
To pursue questions about what
was happening in the brain, investigators used brain imaging, and particularly
noticed activity changes in the amygdala, a structure deep within the brain
that is hyperactive in the presence of fear memories. On the third day, all
subjects were brought back to the lab and brain scans run when the fearful
image was shown. In those subjects in the six-hour group, activity in the
amygdala predicted whether signs of fear (skin conductance) would return. No
such prediction occurred in the 10-min group. In other words, people who lost
their fear memory, as indicated by skin sweating, also lost the signs of the
memory in the amygdala. Similar effects were seen in the network of other brain
areas linked to the amygdala in the processing of fear memories.
None of this should have been
surprising. Back in the 1960s, I and many others conducted studies in animals
that showed memory of a learning event depended on what happened shortly after
the learning. We knew that this short window of time was vulnerable to other
mental events that could prevent memory consolidation. Implications for education
were obvious: multi-tasking, for example, introduces mental events that
interfere with memory consolidation. But one wonders why it took science 50
years to apply what we knew about consolidation to the treatment of anxiety
disorders. The key was the recent discovery that recall of a memory puts it
back in the vulnerable position of having to be reconsolidated.

Judging Learning Effectiveness During Learning
When students study, they may monitor their progress during
a study session by periodically forming judgments on how well they are
remembering the material. Such judgments guide how much further study is deemed
necessary. Researchers have studied this matter in the case of paired associate
learning (where you learn lists of word pairs like dogs-cats, newspaper-book,
etc.). In particular, researchers looked
for correlations between later memory recall either immediately after learning
or after a short delay in which judgments about learning are based on a covert
attempt to recall. Results indicate that making judgments about how well
something will be remembered can be just as efficient as taking an actual test.
In delayed judgments, the student typically makes an initial
covert recall effort and then, based on that, judges how well the material was
learned. Future recall tends to correlate with predictions on recall on a
future test. That is not so surprising, other than the fact that other studies
have shown students over-estimate what they have learned and under-estimate how
much additional student would be beneficial.
A retrieval attempt directly reveals evidence of how well
memory has formed. The act of retrieval itself may enhance learning. Successful
retrieval could constitute an additional reinforcing learning opportunity.
Indeed, other studies have shown that testing may lead to better final recall
than a comparable amount of study. When an item is retrieved in covert recall
and leads to a high judgment of learning, the item gets a long-term memory
boost.
In the present study, the
researchers directly compared final recall and delayed judgments of learning of
paired association of lists of 40 words in Swedish (the native language of the
subjects) and Swahili under differing testing conditions. One hundred
twenty-one Swedish college students were divided into experimental groups: 1)
repeated study and testing (study-test, “ST group”), 2) repeated study and
termination of testing after the first successful recall test (study-test, dropout,“STd”
group), and 3) repeated study and judgments of learning (study-judgment of
learning “STjol” group).
Testing involved presenting the first
word of a pair to serve as a cue to probe for recall of the associated word.
All groups received four initial learning episodes with 5 seconds per item,
after which they had 8 seconds to respond to test on the item (ST, STd) or
render a judgment on their prediction of cued recall for that item a week later
(STjol). All groups were compared for their performance on the same test a week
later.
The ST group went through four successive study-test sessions,
in each of which they studied all 40 word pairs on a computer screen. Immediately
at the end of the list, the students took a 30-second distractor test (math
quizzes). Then their recall was explicitly tested by presenting each Swahili
word, whereupon they had 8 seconds to provide the Swedish equivalent. Students
experienced four such study and test sessions. A similar procedure was used for
the STd group, except that on any given test, each correctly recalled item was
dropped from subsequent tests; thus the number of word pairs dropped from 40 on
the first test to the number of pairs missed on the previous test.
The STjol group experienced a similar process including the
30 second distractor task, except that the test trials were replaced by jol
trials. That is, instead of being required to provide the Swedish word that
matched the Swahili probe word, the subjects were given 8 second to render a
judgment for each word pair by answering this question: “How certain are you
that you will recall the Swedish word in a week when we test you again? “ Students
used a rating scale of 20% sure, 40%, 60%, 80%, 100%.
During the learning phase, the two ST groups increased their
scores at about the same rate from the first session to the fourth. Thus,
dropping a pair from testing once it was recalled correctly did not seem a disadvantage
to learning. Authors assume the jol groups would have increased scores
similarly, but of course they were not explicitly tested during the learning
phase. Their prediction scores did, however, increase over the four sessions at
a similar rate as recall did in the ST groups.
The key issue was elucidated on the memory test a week
later. The ST group had better recall than the STd group, thus revealing that
dropping items during study had long-term consequences. This is reminiscent of
studies by others on flash cards that showed that best long-term recall was
produced by re-testing with all cards in the deck, including those that were
answered correctly in a previous self-test.
The jol group performed better on the final test than the
STd group but results were about the same as those for the ST group. Thus,
making a delayed judgment during the learning phase about how well one has
learned was just as effective for recall a week later as actually being tested
during the learning phase.
What do we make of that? It seems that to make a prediction
for ability to recall word pairs, a person has to first make a covert recall
effort. If you covertly recall a word readily, you would like give a judgment
rate of 100%, whereas if you struggled with covert recall, you might judge
future recall at only 40%, for example. To make such judgments, the learner has
to monitor the learning in real time. Such monitoring in order to render a
judgment entails covert self-testing, which these results suggest is just as
effective long term as explicit testing.
Such results confirm what we know about memory being
promoted by self-testing, whether explicit or covert. As a practical matter for
study strategies where it is inconvenient to take actual tests during study
sessions, it prudent to conduct covert self-testing wherein a student asks
questions like “how well have I remembered this item?” If the answer is “not
well,” more study is called for. Confident
judgments will tend to be confirmed when taking a real test later. In other
words, making judgments about learning effectiveness during a learning phase
helps a student to monitor progress and know how much time to devote to study.
In addition, making such estimates seems, in itself, to promote learning
because covert self-testing is required.

10 Ways to Slow Mental Decline with Age
Deterioration
of the brain usually sneaks up on us. By the time we realize it, it may be too
late. As we get older, we more frequently start asking questions like “Where
did I put the car keys?” “What was it I was supposed to get at the store?”
“What’s your name again?” Most of us have had to ask questions like this, and
it seems to happen more often as we get older. We can’t turn back our
biological clock, but there are things seniors can do to reduce the rate of
their mental decline. The time to act is while you are still relatively young.
As people age, beginning
in early middle age, many of them experience a brain deterioration that
progresses silently over the next decade or two, sometimes ending in
devastating senility. Behaviorally, aging can cause your reflexes to slow. You
walk and act slower. You even talk slower. Our memory starts to fail,
especially the short-term form of memory ability that is so crucial for
learning new things.
Now that bran-scan technology is widely available,
physicians have discovered that the brain usually shrinks as people get older.
The shrinkage increases the space between the brain surface and the skull. The
cavities that hold cerebrospinal fluid get bigger. Nerve tracts in the brain
shrivel, even leaving gaping holes in the brain. The “dendritic trees” shrivel,
and these have major consequences because dendrites are the parts of neurons
that form the contact points, and their loss reduces brain circuitry. You may
also lose 40% or more of your dopamine neurons, and that may lead to
Parkinson’s disease
For aging individuals, the challenge is to reduce the rate
of their decline. This has created a growth anti-aging industry focused on
vitamins and supplements, fad diets, gym facilities, mind training programs. The good news is that some of these things
work, if they are begun while people are in early middle age. Given that our
country now has so many baby boomers in the over-50 category, it seems useful
to summarize some things people can do to prevent or slow memory decline as
they age. I particularly like the summary at this site.
Here is an expanded list of things I think are especially
important for people entering middle age.
1. Get better
organized. Many things we try to remember do not have to be remembered if
we get better organized. Car keys, for example, should ONLY be in the car, your
pocket/purse, or the same place in your house. Ditto for many other objects,
such as purse, hat, glasses, etc. Life is a lot simpler when you have a place
for everything, with everything in its place. Habit relieves the memory.
2. Make a special
effort to pay attention, concentrate. Research shows that aging reduces a
person’s ability to focus and pay attention. This also means that seniors have
to work harder at filtering distractions, such as when we open the refrigerator
door and forget what we are looking for because we thought of something else
before we opened the door. New learning has to be consolidated to form lasting
memory, and this takes a little uninterrupted time and conscious rehearsal
right after you learn it. Seniors are especially susceptible to having
temporary memories wiped out by distractions.
3. Challenge yourself
mentally. Seek out new experiences, an active social life, and mental
demands such as learning a new language, playing chess, or getting an advanced college
degree. Learning new things always has the benefit of making you feel good
about yourself, and this is especially true for seniors who accomplish things
most people think they can’t do. By the way, there is abundant research
literature showing that a lifetime of vigorous learning helps stave off
Alzheimer’s disease.
4. Reduce Stress. Acute
stress helps you be alert, pay attention better, and increase your chances of
remembering what is happening at the time of stress. But chronic stress,
whether caused by the same or different stressors, clearly disrupts memory
formation and recall. Chronic stress and the hormones it releases can actually
kill neurons and shrink the brain (which shrinks with age anyway, and only gets
worse with chronic stress).
5. Eat foods with
vitamins and anti-oxidants. Make certain you have a balanced diet.
Supplements usually won’t help memory unless you have a nutritional deficiency.
But even with a good died, adding vitamins C, D, and E can be helpful. Several
research studies indicate a memory benefit from eating foods loaded with
anti-oxidants. Blueberries (especially on an empty stomach). Another potent
anti-oxidant is an ingredient in red wine, resveratrol, but there is no way you
could drink enough; however, resveratrol supplements are now on the market.
There is also suggestive evidence for memory improvement from omega-3 fatty
acids and folic acid. Pharmaceuticals to improve memory are in the works, but
you may have to wait quite a while before research shows which ones really work.
6. Don’t get obese,
especially in middle age.
Confocal microscopy reveals
that every added pound of fat adds approximately one mile of capillary tubing.
Obviously, all these added vascular tubing puts a strain on the heart. A diet
that produces new fat may well contribute to hardening of the arteries, which
in turn compounds the added workload on the heart. People who are obese
commonly have high blood pressure and other risk factors involving metabolism.
Obesity is a common cause of diabetes, which adds its own
toll on blood vessels and the heart, as well as on nerve cells. No wonder then
that obese people may develop mental deterioration. The problem may be worse in
women. The more a woman weighs, the worse her memory. No, I am not a chauvinist
pig. This claim comes from actual research —by a woman, no less. Diana Kerwin
and her colleagues at Northwestern University studied 8,745 ages 65 to 79 and
found that for every one-point increase in body mass index, the score on a 100
point memory test dropped by one point.
A likely cause of mental decline in most people is
diminished blow flow in small vessels that are easily plugged by cholesterol
and lipids or ruptured by high blood pressure. These “mini-strokes” are
probably quite common as we age, and though they go undetected, they cause a
cumulative damage which progressively affects our behavioral and mental
capabilities. Brain cells are among the most metabolically active of all cells:
they constantly fire electrical pulses and secrete relatively huge amounts of
secretions (neurotransmitters). The brain consumes about 20% of all the body’s
oxygen, even though it only ways about 3.5 pounds.
When brain cells do die or are damaged for any reason,
healthy neurons are assaulted by inflammatory chemicals, like cytokines, that
are released by the brain’s immune cell system. Fat deposits not only stress
the heart, they also increase the amount of cytokines, which are hormones that
can cause inflammation. Brain inflammation is also commonly caused by
infections such as colds and flu and by diets deficient in anti-oxidants.
7. Exercise the body.
Though exercise doesn’t do much to cause weight loss unless you are a
marathon runner of tennis singles champion, it has many other benefits
(improved circulation of blood to the brain, improved levels of HDL cholesterol)
that can directly benefit memory and cognitive function. Vigorous aerobic
exercise can improve your circulation and perhaps blood flow in the brain. But
there also seem to be memory benefits from exercise that is independent of
blood circulation. We don’t know why. Maybe relief of stress and improved mood
are factors. We know that positive emotions help memory, but for unknown
reasons.
8. Exercise the
memory. The more you make an effort to memorize, the easier it seems to
get. Practice the memorization tricks used by “memory athletes” that I describe
in my book. I describe in my book specific image-based systems (“peg systems”) for
performing astonishing memory feats, such as card counting, remembering long
strings of numbers, and remembering the gist of what is on every page of a
magazine or book.
9. Get plenty of
sleep. Many studies show the brain is processing the day’s events while you
sleep and consolidating them in memory. This kind of “off-line” rehearsal
occurs just for the learning experiences on the day of sleep. Naps help too!
How’s that for good news?
10.
Believe in your brain’s ability to get better. Of course genes and luck
have a lot to do with how well one ages mentally. But genes and luck seem to be
more common in people who do the nine things mention above. Too many seniors
buy into the popular myth that old dogs can’t learn new tricks. They resign
themselves to defeatism. But the bottom line is that, unless you have
Alzheimer’s disease, you can improve your mental sharpness. Getting older has
enough frustrations. Don’t compound them by tolerating mental decline. Enjoy an
improved brain.

TV and Education Re-visited
When television first became popular around 1950, it was
dominated by such shows as the Milton Berle comedy hour, “I Love Lucy,” and
professional wrestling. Those who missed out on the halcyon days of early
television might enjoy reading about
its history.
The potential for a damaging
impact on education was recognized at the outset. In 1950 Boston University's
President Dr. Daniel L. Marsh warned that “if the [television] craze continues
with the present level of programs, we are destined to have a nation of morons.”
Well here we are. Just look at how voters re-elect incompetents, panderers, and
demagogues.
Quick to jump into the breach
anticipated by the brain-eating monster of TV, a new movement of “educational
TV” sprang up. National Educational Television was born on May 16, 1954 and
was a non-profit effort to bring educational programs to the masses. The
network was not sustainable as such and was transformed into the Public
Broadcasting Service (PBS) in October, 1970, which continues to the present.
Many of the stations are university affiliates that have in modern times made
some attempts at education, but the programming now is devoted largely to music and news. In the
early days, if you got up at five AM you might learn a foreign language or
something else educationally useful. I remember around 1965 seeing my
5-year-old son looking at test patterns and then a college physics course,
while waiting for the cartoons to come on. I’m sure he didn’t learn much
physics. Today, educational efforts can still be found on television, but most
such programming is distributed over the Internet.
I, among numerous others, am most
concerned about how television affects childhood brain development and
capability for learning. It steals time away from doing things, such as
interacting with others and playing with objects. Language and communication
abilities are stunted because TV communication is unidirectional. Kids don’t
generate communication, they just receive it. The Raise
Smart Kid website cites scholarly reports showing that TV viewing takes
away time from reading and improving reading skills through practice. Kids watching cartoons and entertainment
television during pre-school years have poorer pre-reading skills at age 5.
The corrosive nature of
television’s effect on childhood intellect has only grown in recent years. The
Online College Course’s website has a telling info-graphic titled “This
is your child’s brain on television.” Can you believe it―by
the age of three, 1/3 of children have a TV in their room. The average child
watches 1500 hours of TV a year, but only goes to school 900 hours a year. Only
a few of the shows that young children watch have much educational value. There
are a few exceptions: Sesame Street
and Mr. Robert’s Neighborhood got
5-apple ratings for educational usefulness. But a lot of the other stuff is
just plain junk. Moreover, a lot of what kids see is not age appropriate,
commonly with sex and violence.
The website points out some of
the deleterious effects on attitudes and behavior when young children spend too
much time watching television. I want to focus on two issues related to
learning to learn. One area of concern is learning to read. Reading, for those who
do it well, is the most efficient way to learn. But kids these days tend not to
read well. Many don’t want to read, and they were probably conditioned that way
by watching too much television. TV is the easy way to get information: you don’t
have to do anything―just sit there like a lump and watch.
A study reviewed in the Huffington
Post revealed that American high-school students, when they do read, read
books that are at the fifth grade level. Of the top 40 books teens in grades
9-12 are reading in school, the average reading level of that list is grade 5.3.
Another study established that 67% of U.S.
students are reading below grade level. I know these are real problems. I
interact with dozens of teachers at professional development workshops, and every
teacher I have asked say their students are two or more years behind grade
level.
The other problem that nobody
seems to talk much about is the learning passivity imposed by television. Young
people are being conditioned, much like Pavlov’s dogs, to be passive learners.
Learning how to learn well requires active engagement. Good learners must train
themselves to generate and sustain interest, to pay attention, to grapple with
ideas, and integrate knowledge into ever-evolving learning styles and thinking schema.
Reading does that. Good learners do things with their learning: they grow the
depth of understanding, they hone creativity skills. “Hands-on” learning activities
can help young people develop such skills, although “minds-on” activities are
much better. In any case, promoting such skills is something that TV, even
educational TV, does rather poorly.
So the next time you get up in
arms about our failing schools, remember that a childhood filled with TV is
probably a big part of the problem.

Brave New World of Gene Change in Brain
In recent years scientists have discovered mobile pieces of genetic material that move around inside cells. These pieces are called retrotransposons. They can copy themselves and insert near and into DNA and thus induce mutations. Australian research recently reported in the journal Nature reveals that retrotransposons can alter the genome of human brain cells. In fact, retrotransposons more effectively penetrate neuron genes than those in blood cells that were used for comparison. Thousands of retrotransposon mutations were seen in two of the five areas examined from brains of human post-mortem donors.
Though these pieces of DNA are not genes, they interact with genes that hop around to different sites within a chromosome (perhaps you heard about Barbara McClintok’s 1983 Nobel Prize winning discovery of “jumping genes”). All cells have enzymes that cut transposons out of a string of DNA, which then insert back in at other locations in the DNA. Sometimes the cut includes an adjacent gene along with the transposon, and thus when reinsertion occurs the gene hitchhikes along to the new location. The jumping around is not random; it occurs preferentially into active protein-coding regions, even sometimes in a different chromosome. The potential for changing function is enormous, yet we don’t know just what functional consequences occur. We do know that the process is most common in humans and higher primates.
We have known for some time that all cells are influenced by epigenetic effects; that is, events in the environment can alter the genome. The mechanism may well involve retrotransposons. Gene manipulation may be especially robust for altering learning and memory. It may be no accident that retrotransposon mutations were seen in human hippocampus, the brain region most directly involved in forming memories and the one part of the brain where new cells are continuously born in adults. Memory of learned events results from more or less lasting changes in the junctions (synapses) among cells in the circuits that processed the learning. These lasting changes are enabled by new protein production in those synapses. That protein is under genetic control (thus a memory can be sustained because the genes can replace any protein that degrades over time).
Aldous Huxley, 1894-1963 |
The implications of this discovery for learning and memory―and brain function in general―are inestimable. More importantly, and here is where the “Brave New World” comes in, there should be the potential for manipulating gene functions in predictable and lasting ways by using synthetic transposons (which should be easy to manufacture). Transport of synthetic retrotransposons into neurons might be accomplished by packaging them with a harmless virus; the basics of “transfection” technology are already well established. The hard part will be in discovering what transposons produce desired changes in brain function. But it seems reasonable to test various retrotransposons in the hope that some can be found that will help to cement or magnify memories and perhaps others that erase unwanted memories, as occur in post-traumatic stress syndrome. There is a potential down-side, however. Some retrotransposons may be a cause of cancer.

What's New in Brain-based Learning
In an earlier post, I
explained the new trend of “neuro-education.” Science is discovering many
things about learning and memory that have not yet been incorporated into
school programs. Schools are so focused on teaching kids what to know to pass government-mandated
tests that they don’t seem to get around to teaching students how to develop
their capacity to learn and remember.
On-line Universities.com has
just posted a very
nice item on how “neuroscience is changing the classroom.” The post
explains nine neuro-education interventions:
1.
Cognitive
Tutoring. There is a current system for algebra
that employs computer-based
AI to adjust to student needs as well as to track student progress and thought
processes so teachers can better help them learn.
2.
High
School Starts Later in the Day.
Because adolescents don’t get enough sleep and are not fully functional in
early morning, some schools are starting school later. I agree with this policy
and go further to suggest an afternoon nap (recent memories are consolidated in
a nap).
3.
Spaced
Learning. Students learn more when episodes of learning are spaced
out over time rather than pushed into one single episode. Many teachers
already do that, but all of them should, because research has clearly
established this is the best way to form lasting memory.
4.
Individualized
Instruction. This is too labor intensive to be very
practical, but digital tools are becoming available to help. In addition, teachers are being encouraged to expose
students to novel experiences when presenting information to build entirely new
neural connections or to connect new information to previous experiences
students have had. A problem in the past, I think, is that teachers have
surrendered to the notion that learners should always use their preferred mode
(visual, auditory, kinesthetic). I think they should use all three to expand
their capabilities.
5.
Less Down Time.
The blog used another heading, but two ideas here are well established yet in
great need for more implementation. One is to get students to read more. Research has
clearly established that people who
read more challenging books often have a greater variety and
number of neural connections. Yet, most adolescents notoriously avoid
reading, and many teachers let them get away with it. The other sorely needed
intervention is to have shorter summer breaks, year-round school, and more
frequent short breaks.
6.
Better Identification and Remediation of Learning
Disabilities. ADHD and dyslexia are
the two big problems. Research is still revealing that we have not optimized
remediation practices, but useful things are available that are not always put
into practice.
7.
Fun Learning Environment. Positive reinforcement is the most powerful teaching
tool there is. A fun environment, even including friendly games and
competition, works. More teachers should try it, as long as they don’t get so
wrapped up in the games that academic rigor is watered down.
8.
Team Learning.
Students remember information better over the long
term if they learn in groups. There are well-known formalisms for
effective team learning. Doing
this over the Internet can be especially useful. Not enough teachers know
or use team learning in optimal ways.
9.
Neuro-education Findings. The idea is to spend less time on teaching content and
more on strengthening and developing the brain
itself. There is a whole lot already known that is not being implemented
in schools. More application is inevitable.
I do what I can with my e-book, Better Grades, Less Effort, and with my new book, Power Memory 101, which the publisher is releasing
this August.
NOW RECRUITING TEACHERS: I am developing a new teaching resource for middle-school
science. The lessons are based on “brain-based” teaching or “neuro-education.”
The idea is to teach students aspects of brain function that will help them
perform better in school. I have now added some of this material to the brain section of our Organ Systems module of our middle-school website.
In addition, I have invented a
new system for teaching, learning, studying, and remembering all in the same
visual and conceptual environment. That environment is created as a “one-card”
virtual flash card that contains neuro-education material that would cover 1-3
typical class periods. The system is based on a PowerPoint file that contains a
table. Icons representing key concepts are placed on the top left corner of a
cell, with associated text information placed as bulleted text in the
corresponding cell. Each object is then tagged for animated display upon mouse
click anywhere off screen. Lectures, study, and self-testing occur in
slide-show mode wherein the user navigates the single screen by mouse click
from icon to associated text box to next icon, etc.
The system would seem to have
the following beneficial features: comprehensive, holistic access to all the
information, compact, flexible/extensible, cohesively organized, easily and
quickly studied, self-tested in flash-card style, embodied key memorization
principles, and easily constructed and modified.
What I Pledge to You:
1. You get a free e-copy of
the flash card and access to the instructional material.
2. My promise to maintain
your anonymity, while retaining the right to pool survey data from all
participating teachers and their students.
3. An e-copy explaining how
to create and use the one-card flash-card invention.
4. Notice of when and where a report of the
findings is published, and an electronic copy of the report.
What You Need to Agee to Do:
1. Agree to teach at least
one middle-school class period this Fall from the “flash card” and give a study
copy to each student.
2. Fill out a simple website
survey of your opinions. Have your students fill out a simple website survey of
their opinions.
3. Get on the waiting list by sending me your
name and e-mail address to wklemmATSIGNcvm.tamu.edu |

Teaching Kids to Think
Learning how to learn is a major objective of schooling.
Yet, in my view, the emphasis in most schools is on WHAT to learn, not HOW to
learn. My Improve Your Learning
and Memory blog is aimed at filling that gap, yet these useful ideas have a
hard time penetrating curricula that are designed to teach to
government-mandated tests.
Yet another, apparently unmet, challenge in education seems
to exist: teaching students how to think. A recent U.S. Dept. Education survey
reported in the Nation’s
Report Card suggests that science students may be learning how to perform
simple investigations but do not do well
in thinking about the meaning and implications of the results and how to
use data to make decisions.
About 2,000 students in each grade level 4, 8, and 12 were
tested in three real-life science problem-solving scenarios in an interactive
computer test environment. Anybody can take the tests, which are posted on the
NRC website; the tests are easy and fun. The test records results of each
simulation (you control the test parameters), your answers to the questions,
and then provides the average test scores of students who participated in the
survey. The test I took (8th grade bottling honey problem) consists
of computer simulations where speed of a steel ball dropped into four different
liquids is recorded at different temperatures. Students can repeat various
temperature conditions at will, and then they answer questions requiring
deductive conclusions. The questions were not hard, but you do have to pay
attention and think. What is disturbing is that on several of these questions
the vast majority of students got it wrong. Even when they got the right
answer, many students could not give the proper explanation for why it was
right.
Last month, the agency reported results from a
paper-and-pencil test given last year which showed that less than a third of 8th
graders performed at a “proficient” level.
Results like these are prompting a re-thinking of national
science standards, which I discussed in a
recent blog. The new emphasis is to shift from rote memorization of subject
matter to building students’ deeper understanding of core science concepts, how
they connect, and how they can be applied to the real world.
My response to this need is to explore how scientists
communicate and share their thinking to solve problems. The answer is that they
publish their research in articles that emphasize how and why they conceived of
the problem, how they designed experiments, and how they interpreted the
results and their implications. The results of research are only one aspect of
the report. Yet, in school science, teachers and government tests typically
focus on the results of research, and even then after the results have been
filtered through multiple layers of re-formatting and condensation.
I asked myself, “Why can’t we teach science more like the
way it actually occurs in the real world?” The answer is that of course we
could, but scientific journal articles are too difficult for students to
understand. Or are they? What if good science writers re-wrote research reports
in simple, clear language that even an 8th grader can understand?
And then we could require students to critique the paper in terms of rigorous
questions that required students to think critically and creatively.
Well, I am trying to start just such an initiative. I have
re-written about six published research
reports thus far, hopefully at middle-school level, and provided a set of
24 scaffolding questions to guide student thinking.
We will see whether or not this catches on with teachers and
educational administrators.

A Portal for On-line Memory Techniques
A reader of this blog, Bruce Hopkins, recently told me about
his new web-site portal for web-sites on memorization techniques. This site (bruce.hopkins@memorymethods.com)
is a wonderful resource. I just checked a few of the links and was pleased with
what I found. Much of the information I already know, being the “Memory Medic,”
but I learned some new things.
For example, the site that explains the “phonetic
system” for memorizing numbers (http://www.got2know.net/)
convinced me that you don’t always have to create words that are nouns. I have
always thought nouns were essential, because they can be represented in a
visual image. For example, I represent the number one with “tie,” but this site
also suggests “the, do, and it.” While the latter three words have no visual
image, they can be used to construct acrostics. That brings me to the site’s supposed
best feature: it claims you can type in any long number and get an acrostic.
But I could not get the interactive part of the site to work either on IE or
Chrome.
A few sites focus on specific
topics, such as medicine or chemistry. The medical site (http://www.medicalmnemonics.com/)
has a browsing index that allows you find all their memory tips for a given
body function. The chemistry site (http://img.com.tripod.com/mnemonics/chemistry.htm)
has some good acrostics for memorizing the periodic table.
Another site has an interesting
approach to memorizing text verbatim, as in Bible verses, speeches, quotations,
etc. (http://www.productivity501.com/how-to-memorize-verbatim-text/294/).
The emphasis is on recalling not repeating. This fits nicely with my view that
self-testing is the key to good memorization. In this site’s approach, you
re-write the text’s first letter of each word, and then practice recalling the
original words by looking at the letters. The site even has dialog boxes where
you can type in the text to memorize and it will display the first letters of
each word you typed.
Another interesting site
generates the equivalent of flash cards (http://fullrecall.com/). The software is similar to common flashcard
programs: knowledge is stored in question-answer pairs. You add the
question-answer pairs yourself. In review mode you are presented the questions,
one by one. To every question you'll think about an answer, and after a while
you'll be confronted with the correct answer. After seeing the correct answer,
you'll be asked for a grade that estimates how well you remembered the correct
answer.
Another flashcard site (http://www.flashqard-project.org/)
is very robust. Each computer generated flash card can accept multiple images
(remember images are easier to remember than words) and has a search tool for
on-line images. It even has a score tracker.
Some of these sites have links to
other sites. For example, I stumbled on Anki, a flash card system that
synchronizes your cards across multiple computers, and has a smart-review
algorithm that schedules the spacing of self-testing sessions based on how
difficult you thought each given card was to answer. See http://ankisrs.net/
In addition, there are links to several
mind map programs, dictionaries, repositories of synonyms and rhymes.
I look forward to seeing Bruce’s
portal evolve as he finds and adds new memory sites.

More on Jazz-band Teaching & Learning
I probably need to explain a couple of learning principles
mentioned in the original post on jazz-band teaching and learning. One principle
is operant conditioning, which is inherent in band classes. It will truly pay
off to find creative ways to employ operant conditioning in academic-course
classes, because it is the most powerful teaching technique I know of. I assume
they teach this in colleges of education, because kindergarten teachers do a
version of it all the time with the “gold-star” reward paradigm. Fully
implemented, the idea is that little successes bring little rewards, and as the
desired behavior becomes established, the bar is raised for further reward, or
positive reinforcement as the psychologists call it. A repeated process of
“successive approximation” can lead to astonishing results in short order. I
think that something like this is operating in band class.
The reward in jazz-band, and that includes orchestra band
class, is the immediate gratification a student gets when playing a few new
notes or chords, for example. In band, learning something new is usually done
in small readily accomplished steps, and there is immediate feedback from
hearing what is played and/or comments from classmates or the band director. Contributing
successfully to the band effort is also rewarding, because all students know
they are “on the team” and making a needed contribution. For emphasis, I repeat
the four key elements of operant conditioned learning:
- learning occurs in small
successive steps
- with each step the student
DOES something
- feedback is immediate
- positive reinforcement follows.
The second key principle is “deliberate practice,” which is also
an inherent feature of band class. The idea is not only to practice but to planning
specific strategies and tactics for the practice. Teachers, of course, have a
plan for teaching each given content item, but that is not the same as the
student having a learning plan. Teaching and learning are not the same, and the
problem in schools is usually traceable to inadequate learning.
The
best learners bring conscious design, awareness, analysis, and correction of
error to their learning efforts. This is exactly what has to be done in band
class. For example, the learner, guided by the band director, has to develop an
approach to move from each small step of mastery, such as playing a few new
bars, to learning the whole sheet music score.
“Memory athletes” use this kind of memory
practice to rise above their own innate memory capability, which is usually not
much better than anyone else’s capability. This is the kind of practice
performed by superstars in any field: music, art, business, sports, science
(and straight-A students and stellar jazz-band players).
Superstars reach that level of
achievement by:
•
Having the passion,
resources, and time to learn their craft. This means making a commitment to becoming a better learner.
•
Working hard at their
craft with smart, intentional planning
to improve their basic competencies in very specific ways. In the process of
mastering a specific learning task, they are also “learning-to-learn.”
•
Raising
their goals to new and more challenging goals. This
includes identifying people to compete against.
•
Structuring practice in
ways that provide constant and detailed
feedback.
•
Continually expanding their knowledge base. This
includes learning the tactics others use successfully in study.
•
Focusing on improving weaknesses.
•
Receiving
encouragement and help from others. This means
having access to a circle of friends and mentors who value achievement.
The
last bullet item comes from fellow students in the band, because they need each
other to perform well and share in the applause when they perform in public. Peer
support is central to success of athletic teams. Academic classes would surely
benefit from finding ways to develop team spirit.
All of these things require students to be motivated. I
emphasized this in the original post, in the context of the passions generated
by jazz. Passion is harder to generate in academic classes, but it is no less
important.

What All Teachers Should Learn from Jazz-band Teachers
I just came back from a
jazz festival at Katy High School in Texas that show-cased student stage bands
from ten schools mostly near Houston, but some as far away as Beaumont and
Brownsville (the latter band stole the show).
The festival was also a
teaching event, with each band or ensemble performing for 30 minutes, followed
by 30 minutes of critique from six professional jazz musicians (two of whom
were music professors at universities). The critiques were shared with the small
audience consisting almost exclusively of family and friends, even though this
festival was advertised for the general public. Performances were staggered so
that if you didn’t want to hear a critique you could go hear a student combo
and vice versa. The facilities were magnificent, highlighted by the presence of
a natatorium, impressive athletic fields and stadium, and a Performing Arts
Center where the festival took place. If Texas schools are hurting for funds,
it certainly wasn’t evident at Katy High School.
I was astonished at how
accomplished these students were. I asked myself, “How did those kids learn
such complex music? The music played was mostly the big-band music of Goodman,
Basie, Kenton, Ellington, and others from the eras of swing and “progressive/modern
jazz of the 50s and 60s.”
Jazz is sophisticated
stuff. Yet these 16 to 24 kids in each band could do what a lot of adult
musicians cannot do. One band was a middle-school band, and the professional
musicians who critiqued each band’s performance were amazed that these 7th and
8th graders “played like adults!” Jazz fans everywhere
lament that jazz seems like a dying art form overwhelmed by the simpler music
of country, rap, hip-hop, and whatever it is that most kids listen to these
days. But the professional “coaches” at the festival reassured the audience
that “jazz is in good hands.” Fortunately, many school and university music
programs teach jazz.
Learning to playing any
musical instrument is hard, but playing jazz is the ultimate challenge. In jazz
you not only have to know the tunes, you have to use the chord structure and
complex rhythms to compose on the fly. A jazz professor from the University of North Texas counseled in one of his critiques, “I know you have sheet music you
have to follow, but when you hear something in your head, play it. That’s what
we (jazz musicians) do – improvise!”
Another jazz professor,
during a critique session had two bands re-play a number from their
performance. About one third of the way through, he silently and casually
walked through the rhythm section (piano, guitar, bass, and drums) and picked
up the sheet music. The kids went right on playing without skipping a beat,
because they had already memorized the sheet music. His point was they were
using the sheet music as a crutch and not engaging with each other. Musicians
talk to each other with their instruments, and listening is a big part of jazz
improvisation. Students needed to be engaged with what each member of the
rhythm section was doing, and, moreover, the rhythmic section needed to
interact with the saxes, trombones, and trumpets.
Hearing such wonderful
music from children raised a nagging question. Why can’t kids master
complicated science, math, language arts, or social studies? Why does everybody
struggle so mightily to get kids to pass simple-minded government-mandated
tests in academic subjects?
And then it hit me.
Jazz-band teachers do the right things in teaching that other teachers need to
learn how to do.Two things are essential
in teaching, the professionalism of the teacher and the motivation of the
students.
Most school jazz programs provide both. Sad to say, this is not so
true of traditional curriculum.
Consider professionalism. It was clear that these band directors really knew what they were doing. Some had professional playing experience. Most, I am certain, were music majors in college. Think about what they have to do. They take young kids who know little about music beyond humming a tune and teach them music theory, teach them to read music, and teach them to play the different instruments in a band. And then they have to teach students how to compose on the fly. You can’t do that without being a real professional.
As for motivation,
teaching and learning jazz involves clearly identifiable motivating features.
Jazz-band teachers can’t take credit for some of these features, but creative
teachers in other subject areas can think of similar motivating things they
could be doing, based on what is involved in jazz.
First, there is PASSION.
Jazz stirs the emotions, from blues to ballads to hot swing. If Benny
Goodman’s music doesn’t make you want to jump up and dance, you better check
your pulse to see if you are still alive. That brings up this point: jazz is
FUN! Learning chemistry, for example, is almost never considered by students to
be fun —but teachers should be thinking of ways to make it fun.
Some academic subjects
do have intrinsic emotional impact. If, for example, the emotions of history
students are not stirred by the Federalist Papers, or the turmoil of the Civil
War and the country’s other wars, then history is not being competently taught.
If the beauty of the laws of physics and chemistry or the biology of life are
not evident in the teaching of science, it is the teacher’s fault.
Second is that jazz is
PERSONAL. A jazz student intellectually owns his instrument. He or she owns the
assigned space on the bandstand. One critiquing musician at the festival
reminded students they own that space and if the sheet music stand or the audio
at their station was not left just right from the previous band, they must fix
it. It is now their space.
How well a student has
learned jazz is public knowledge. They can’t hide. What you know and can do is
on public display, all the time in practice sessions with fellow band members
and, of course, in public performances. In marked contrast, it is against the
law for teachers in other subject areas to reveal grades on individual
performance, even within the more private area of the classroom. The belief
system in education these days is that you should not allow an unprepared and
under-performing student to be embarrassed. What dingbat policy maker came up
with that? I know; it comes from the perverse politically correct movement that
ignores the reality that self-esteem needs to be earned.
Third is that jazz is
ultimate CONSTRUCTIVISM. All teachers know about constructivism, which is the
idea that students have to do something to show they have mastered the learning
task. Student jazz bands and combos demonstrate personal accomplishment all the
time in rehearsals and stage performances. But in many traditional courses, the
main constructive thing students do is fill in circles on a Scantron test
answer sheet. In science, “science fairs” encourage constructivism, but these
are usually one-time events. Students need to be doing something every
day to demonstrate their learning. In English, how often to students write and
re-write an essay, poem, or short story? Does anybody write book reports anymore?
Do students spend hours of writing and editing comparable to what a
jazz student spends in practice? In social studies, how many students are
required to explain and debate capitalism, socialism, fascism, democracy, and
republican government?
Fourth, jazz is SOCIAL
Jazz students perform as a group, either in a big band or combo. Recall the
earlier example from the festival where the professionals had to emphasize this
point by taking away the sheet music. Students had to learn to talk and listen
to each other through their instruments. In traditional education, there is a
movement called collaborative learning,the idea of learning
teams, but many teachers don’t use this approach or do it without regard to the
proven formalisms needed for success. Regardless of academic subject, students
benefit when they learn how to help each other learn.
Part of the social
aspect off jazz is competition. In many schools, many students don’t have to
compete to get into a music class. But once in, they have to display learning
in order to advance into more prestigious classes (think the “One O'Clock Lab Band”
band at the University of North Texas). In whatever music lab they are in, they
have to compete for “first chair” in their instrument section. It is like
competing to make the varsity and then the first team in sports. Where is the
equivalent in science, social studies, or language arts?
Unlike traditional
education, where the goal is to meet minimum standards on state-mandated tests,
jazz band directors make very clear their HIGH EXPECTATIONS that everybody in
each band class should become as proficient as they can. The whole point of
their teaching is mastery and excellence. They expect excellence and they get
it, as witnessed by festival performances such as I saw. Thanks to the
unenlightened thinking of No Child Left Behind law, our public education has
degenerated into “No Child Pushed Forward.”
And finally, consider
the matter of REWARD. Somewhere in the college courses of teachers they learned
about “positive reinforcement,” and most teachers try to use these ideas to
shape the learning achievements of their students. But jazz performance
provides public reward, in the form of public applause.
Is there anything comparable in the teaching of science, social studies, or
language arts? Is publishing (inflated) Honor Roll lists in the newspaper the
best we can do?
So in a nutshell, the
reason jazz students do so well is because their learning environment is built
around:
- Passion
- Personal ownership and accountability
- Constructivism
- Social interaction
- High Expectations
- Reward
What I took home from
this experience is a renewed feeling that outside of jazz music programs our
schools are letting our children down. These young musicians prove that when
motivated, challenged, and taught professionally, they can do astonishing things. The printed program for
the festival concluded with the comment, “The future belongs to those who are
able to capture their creative intelligence. Jazz music education and
performance develop the ability to create and produce the ideas that are
individually unique.”
Why doesn’t the rest of
education do that?
This festival experience leads me to suggest a "Ten Commandments for Better Teaching:"
Ten Commandments for Better Teaching
1. Love your students as yourself.
2. Be professional. Know the stuff you teach.
3. Instill passion for the content - especially, make knowing fun.
4. Make learning personal. Show students how to own their learning.
5. Take away the hiding places of unprepared and under-performing students. Let them embarass themselves.
6. Show students they have to earn self-esteem. You can't give it to them. Praise success and do so publicly when it is earned.
7. Require students to do things that show they have mastered what you are trying to teach.
8. Give students opportunities to "strut their stuff" in public, in and out of the class.
9. Help students learn how to work with others as a team.
10. Expect excellence. Do not teach to the lowest common denominator.
