Despite a recurring stream of educational fads, lectures
still dominate teaching approaches. In spite of such teaching reforms as
"hands-on" learning, small group collaborations, project-based
learning, and others, teachers generally can't resist the temptation to be a
"sage of the stage," instead of a "guide on the side." And
when they are not lecturing, teachers may assign instructional videos. Maybe
that's a good thing, because many students are not temperamentally equipped to
be active learners. Rather, they have been conditioned by television and movies
to function as a passive audience. Even the way we test learning with multiple-choice
questions conditions students to be passive by recognizing a provided correct
answer among three or four incorrect ones.
Then there is the problem of alternatives, such as learning
from reading. Too many students don't like to read academic material. They want
somebody to spoon feed the information to them. Most lectures are just
that—spoon feeding.
Given that the dominance of lecturing is not likely to
change any time soon, shouldn't teachers focus more on showing students how to
learn from lectures or from videos? It seems there is an implicit assumption
that passive listening will suffice to understand and remember what is presented
in lecture or video presentations. The problem is, however, that deep learning
requires active, not passive, engagement. Students need to parse content to
identify what they don't understand, don't know already, and can't figure out
from what they do already know. This has to happen in real time, as different
ideas and factoids come and go.
So how should students engage with presentations?
Traditionally, this means taking notes. But I wonder if note-taking is a dying
art. I don't see many students taking notes from lectures or web pages or
U-tube videos. Or textbooks (highlighting is a poor substitute). My concern was
reinforced the other day when I gave a lecture on improving learning and memory
to college students. The lecture was jam packed with more information than
anyone could remember without being actively engaged. Yet, I did not see a
single one of the 58 students taking notes. Notably, the class's regular
professor, who had invited me to give the lecture, was vigorously taking notes
throughout.
Why don’t students take notes? Are they too conditioned for
passive learning? Is it because they can’t write legibly in cursive, and
printing is too slow and cumbersome? Whatever the cause, it can be traced to
faulty teaching by previous teachers.
Just what is it that I think is valuable about note taking?
First and foremost is the requirement for engagement. Students have to pay
attention well enough to make decisions about the portion of the presentation
that will need to be studied later. Paying attention is essential for encoding
information. Nobody can remember anything that never registered in the first
place.
Next, note taking requires thinking about the material to
decide what needs to be captured for later study. This hopefully generates
questions that can be raised and answered during the presentation. In the
college class I just mentioned, not one student asked a question, even though I
interrupted the lecture four times to try and pry out questions. Notably, after
the lecture, about a dozen students came to me to ask questions.
Notes should be taken by hand. This is a good place to
mention note-taking with a laptop computer. Students are being encouraged to
bring laptops to take notes. Two important consequences of typing notes should
be recognized. One problem is that for touch typists, taking notes on a laptop
is a relatively brain-dead process in which letters are banged out more or less
on autopilot. A good typist does not have to think. And if you have not
mastered the keyboard, paying attention to which keys to hit is a distraction
from the content the learner should be thinking about. Hand-written notes
inevitably engage thinking and decisions about what to write down, how to
represent the information, and where on the page to put specific items. A formal
experiment has been published showing that students remembered more when they
took notes by hand than when they took notes by laptop typing.
A special benefit of hand-written note-taking is that
students create a spatial layout of the information they think they will need
to study. A well-established principle of learning is that where information is provides important cues as to what the information is. The spatial layout
of script and diagrams on a page allows the information to be visualized,
creating an opportunity for a rudimentary form of photographic memory, where a
study can imagine in the mind's eye just were on the page certain information
is, and that alone makes it easier to memorize and recall what the information
is.
This brings me to the important point of visualization.
Pictures are much easier to remember than words. Hand-written notes allow the
student to represent verbalized ideas as drawings or diagrams. If you have ever
had to learn the Kreb's cycle of cellular energy production, for example, you
know how much easier it is to remember the cycle if it is drawn rather than
described in paragraph form.
All learners take in information differently. There are at
least five common types of note-taking. Learners should select the type that
works best for them. The type selected may vary with the nature of the
information source. After reading the different descriptions of note-taking
styles below, it will be up to you to decide which style of notes you would
prefer to utilize.

Matrix Notes
Outline Notes
These notes are
arranged in terms of topic, sub-topic, sub-sub topic, and so on. Each item is
on a separate line and is indented. Each topic or sub-topic can be numbered and
lettered. Here is an example for information on cell biology:
1.
History
A.
Initial discoveries
1).
Robert Hooke
2).
Early microscopes
3).
Etc.
2,
Cells
A. Definition/cell theory
B. Organelles
1) Mitochondria
2) ER
3) etc.
The numbering and
lettering can become distracting. I prefer to use headings, sub-headings,
sub-sub headings. This is readily automated in a word processing by using a
styles menu (Heading 1, Heading 2, Heading 3, and so on). Here is an example:
History (main heading)
Initial discoveries (subheading)
Robert Hooke (sub- sub-heading)
Early microscopes
Cells
Organelles
Mitochondria
ER
Etc.
Outline notes are
most useful when you have to capture information quickly. If you don’t have
much time to think, outlines are usually easy to construct because that is the
way most information is presented in lectures, videos, and textbooks. A
presenter typically presents a main thought, then explains it with some detail,
and then moves on to the nest main idea.
For more
understanding and to promote memory, it is important to think about the words
that appear in an outline. Other note-taking methods require reconstructing the
initial information in a different format, and this requires some thinking.
Thinking is the best way to improve understanding, and it also automatically
promotes memory formation.
Charting Notes:
These notes are put in a table with column headings. Here is an illustration based on cell biology information:

Mind Mapping
Ideas can be mapped in ways that show how they relate to
each other. The map drawing should begin with outlined notes, because few
people can think fast enough to construct a map in real time during a lecture
or video. In simple mind mapping, basic ideas are stated within circles and
arrows are drawn from “parent” to “daughter” circles. A useful addition is to
write in brief text along the arrows that explain what the relationship is.
When this addition is included, the map is called a concept map. Here is an
example:
Each circle object in the map can be expanded to whatever
level of detail is required. In the map above, for example, from “History” you
could add a circle for “Hooke” with a labeled connecting arrow saying “the
first pioneer was.” Maps like this are easily made with paper and pencil. If you
want more formal maps, these can be done in a computer drawing program like
Powerpoint or more automated concept mapping software that is available from
multiple vendors.
Matrix Notes
Matrix notes place information in a table, where the columns
might be categories of information and the rows contain items within each
category. The columns represent one category of information (such as topics and
the rows another, such as items. Here is the basic idea:
Core Ideas
|
History
|
Cells
|
Cell Theory
|
Organelles
|
Structure
|
|
|
|
|
Relation to tissues
|
|
|
|
|
Energy production
|
|
|
|
|
Proteins
|

Etc.

As with concept maps, the process should begin with outlined
notes, because few people can think fast enough to construct a matrix in real
time during a lecture or video. Also, as with concepts maps, the main advantage
is that the learner has to think about the content. The best way to remember
anything is to think about it. Such thinking may also provide insights that
would otherwise not occur.
Matrix notes can be more comprehensive and force thinking
about content in a wide range of contexts. Matrix notes are most useful when
cross-cutting relationships need to be clarified.
The advantages for learning are that the learner
conceptualizes the ideas in the process of constructing the matrix. Because
ideas are presented in one view, preferably in units of one page at a time, it
is easy to see cross-cutting relationships that otherwise are not so apparent.
Such organization is an aid to stimulating insight. In addition, the fixed
spatial layout is a memory aid, because knowing where a given piece of
information is located makes it easier to remember the information.
To conclude, learners will remember more if they take notes
of the learning material. The reason is that note taking requires more
attentiveness, engagement with the information, thinking about relationships
and applications of the information. Notes also provide a condensed personal
copy that can be filed for later reference.

Aw, this was an amazingly decent post..
