Cursive Writing Makes Kids Smarter


Ever try to read your physician’s prescriptions? Children increasingly print their writing because they don’t know cursive or theirs is unreadable. I have a middle-school grandson who has trouble reading his own cursive. Grandparents may find that their grandchildren can’t read the notes they send. Our new U.S. Secretary of the Treasury can’t (or won’t) write his own name on the new money being printed.

When we adults went to school, one of the first things we learned was how to write the alphabet, in caps and lower case, and then to hand-write words, sentences, paragraphs, and essays. Some of us were lucky enough to have penmanship class where we learned how to make our writing pretty and readable. Today, keyboarding is in, the Common Core Standards no longer require elementary students to learn cursive, and some schools are dropping the teaching of cursive, dismissing it as an “ancient skill.”[1]

The primary schools that teach handwriting spend only just over an hour a week, according to Zaner-Bloser Inc., one of the nation's largest handwriting-curriculum publishers. Cursive is not generally taught after the third grade (my penmanship class was in the 7th grade; maybe its just coincidence, but the 7th grade was when I was magically transformed from a poor student into an exceptional student).

Yet scientists are discovering that learning cursive is an important tool for cognitive development, particularly in training the brain to learn “functional specialization,”[2] that is capacity for optimal efficiency. In the case of learning cursive writing, the brain develops functional specialization that integrates both sensation, movement control, and thinking. Brain imaging studies reveal that multiple areas of brain become co-activated during learning of cursive writing of pseudo-letters, as opposed to typing or just visual practice.

There is spill-over benefit for thinking skills used in reading and writing. To write legible cursive, fine motor control is needed over the fingers. Students have to pay attention and think about what and how they are doing. They have to practice. Brain imaging studies show that cursive activates areas of the brain that are not affected by keyboarding.

Much of the benefit of cursive writing comes simply from the self-generated mechanics of hand- printing letters. During one study at Indiana University to be published this year,[3] researchers conducted brain scans on pre-literate 5-year olds before and after receiving different letter-learning instruction. In children who had practiced self-generated printing by hand, the neural activity was far more enhanced and "adult-like" than in those who had simply looked at letters. The brain’s “reading circuit” of linked regions that are activated during reading was activated during cursive writing, but not during typing. This lab has also demonstrated that writing letters in meaningful context, as opposed to just writing them as drawing objects, produced much more robust activation of many areas in both hemispheres.

In learning to write by hand, even if it is just printing, a child’s brain must:
  •            Locate each stroke relative to other strokes.
  •            Learn and remember appropriate size, slant of global form, and feature detail characteristic of each letter.
  •       Develop categorization skills.

Cursive writing, compared to printing, is even more beneficial because the movement tasks are more demanding, the letters are less stereotypical, and the visual recognition requirements create a broader repertoire of letter representation. Cursive is also faster and more likely to engage students by providing a better sense of personal style and ownership.

Other research highlights the hand's unique relationship with the brain when it comes to composing thoughts and ideas. Virginia Berninger, a professor at the University of Washington, reported her study of children in grades two, four and six that revealed they wrote more words, faster, and expressed more ideas when writing essays by hand versus with a keyboard.[4]

There is a whole field of research known as “haptics,” which includes the interactions of touch, hand movements, and brain function.[5] Cursive writing helps train the brain to integrate visual, and tactile information, and fine motor dexterity. School systems, driven by ill-informed ideologues and federal mandate, are becoming obsessed with testing knowledge at the expense of training kids to develop better capacity for acquiring knowledge.

The benefits to brain development are similar to what you get with learning to play a musical instrument. Not everybody can afford music lessons, but everybody has access to pencil and paper. Not everybody can afford a computer for their kids−maybe such kids are not as deprived as we would think.


Take heart. Some schools just celebrated National Handwriting Day on Jan. 23. Cursive is not dead yet. Parents need to insist that cursive be maintained in their local school.

How Teacher Labor Market Affects Teaching Quality

Turnover of U.S. teachers is a major reason for our educational problems. In 1987, the modal value of teacher experience has dropped from 15 years to just one year in 2007-2008. Today, 50% of new teachers drop out within five years of entering teaching. Obviously, more and more students are being taught by novice teachers. Once teachers get enough experience to start having positive effects, they quit.

I won't go into the reasons teaching seems unappealing. While salary can be a factor, in my experience with teachers, it is working conditions they find most objectionable.

Numerous other sources have debated such causes as lack of status, misbehaving students, apathetic parents, our general anti-intellectual culture, etc. What I want to highlight here is a new study that explores the relationship between teaching quality and experience - with emphasis on science teaching.

The first good thing this study did was define teaching quality in terms of value added, and they used huge numbers of students and teachers. They monitored over the course of five years the effect of high school teachers on 1.05 million end-of-year exams from over 624,000 individual students and 7,961 teachers. The study covered all the science and math courses and three non-science courses (history, civics, English). Of the issues they examined, two were especially noteworthy: 1) do novice science and math teachers improve with experience? and 2) does the experience effect vary by subject matter? The researchers framed the study this way because numerous prior studies made it clear that teachers and teacher experience are clearly the most important variable affecting student learning.

The next good thing they did was use sophisticated statistics that adjusted for other variables such as prior achievement of students and classroom and school environments. They also disentangled any possible affect due to the possibility that teachers who leave teaching early are less effective, thus giving a misleading impression that the remaining teachers are more effective than they really are.

Results showed that in all subject areas, teacher effectiveness increased in near-linear fashion for the first three years. But then a plateau was reached, and actually showed a decrease by year five for biology teachers. Results also showed science and math teachers who quit by year four were typically less effective than those who stayed on the job.

The implications seem clear. New teachers benefit greatly from early teaching experience, but soon "top out" in effectiveness. Moreover, it is the science and math teachers who have the greatest capacity for improvement, with the steepest growth curves observed for teachers of physics and chemistry. Obviously, students don't learn as well from new science and math teachers as they do from more experienced ones.

In terms of the job market, the high turnover of teachers leads to lower average effectiveness. Another way to think about it, not mentioned in the paper, is the possibility that students don't learn science and math very well because their teachers are not very effective in early years and many of them leave teaching by the time they get good at it. This could account for the poor showing of U.S. math and science students compared with students in other countries.

It's time that educational policy makers addressed three problems revealed by this study: 1) attract better science and math students into teaching careers, 2) provide better initial preparation of science and math teachers, and 3) reduce high teacher attrition.

Save Us From the Education Experts

The New Framework for K-12 Science Education. 
What They Missed.

The National Research Council of the National Academies recently released their landmark epistle, A Framework for K-12 Science Education. This book advocates the practices, crosscutting concepts, and core ideas that students should know at each K-12 grade level. The purpose is to influence the science educa

While I applaud the purpose, I find much to criticize about these recommendations from this august body of experts. I won’t burden you with the details on everything I find lacking, but one whole category of recommendations seems to have been overlooked. Their guidelines say almost nothing about brain and behavior. Students are humans, and the most distinctive and important feature of being human is the brain and the behavior it controls. Why don't we require students to understand more about their brain and behavior, particularly as to the relationships to social interactions, emotions, and learning and memory? This is the one category of human experience where children especially need guidance and education. And in this category something that is especially applicable to school children is the science about learning and memory. We tell school children WHAT to learn (much of which is irrelevant to their life at the moment), but not HOW to learn. That is really bizarre. U.S. education needs to be rescued from the clutches of the establishment “experts.”
