Learning: No Pain, No Gain

The “best” teachers are the one’s who make learning easy. At least that is what the poorer students say. They may be wrong. The popular belief that it is easier to learn things that are easy rather than harder is also probably wrong. Easy material may not elicit enough attention and engagement to produce lasting learning. So, educators may need to re-think the whole notion of what makes a teacher effective. Making learning easier makes the teacher more popular, but that does not necessarily translate to real student achievement.
Kent State psychology professors have just reported a study of this matter with college students. They find that when students think something is easy to learn they may have only a superficial level of learning that does not last much beyond the next test. Just staring repeatedly at learning material is not nearly as effective as forcing retrieval of the information. Moreover, students can develop an easy-learning attitude that leads to bad study habits and an ineffective learning style.
Other research that I have summarized elsewhere shows that students likely do not know material as well as they think they do. That is, if they perceive they have “got it  in the bag,” they may find out they are sadly mistaken at test time. Likewise, students tend to quit study too soon, thinking the material was easy and they have learned it. In fact, repeatedly studying material you assume you know makes it more likely that you really do know it.
Easy learning, as in a single cramming session, is deceptive. It is not nearly as effective as the harder learning of spreading out the study over many days and weeks. The self-testing under the delayed conditions is much more effective precisely because it is harder to recall material learned days ago .
In the Kent State studies, college-aged students were asked to study for a week a pack of 48  flashcards that paired Swahili vocabulary words with their English translations. The students were divided into two groups and in both groups, students asked  to use a mediator — word, phrase or concept — link both words of a pair. Students in one group were given practice quizzes where they were shown a word and asked to name the other member of the pair. An examination at the end of the week revealed that the practice-quiz group performed much better on the final exam, especially if they were asked to recall the mediator.
In a study recently reported at an American Educational Research Association  meeting in by Katherine Rawsom at Williams College, students studied 35 Swahili-English word pairs on flash cards. The students were asked to practice until they got the vocabulary correct using either the entire stack or five stacks of seven cards each. Researchers instructed students to study the flashcards until they had gotten each translation correct either once, five, or 10 times, before taking a final quiz a week later. Getting the stack correct five times was three times more effective for the final quiz than the stack was correct only once. Also, study of one big stack was better than five little ones.
Students had predicted just the opposite. They expected studying smaller groups of flashcards would be more helpful than studying the big stack, and they expected no real benefit from studying cards more than once. They remembered about as many words as they expected to recall when studying the entire pack, 43 percent to 46 percent. Yet those who had studied the small stacks expected to remember nearly 60 percent of words yet recalled only 17 percent. In general, students were incorrect in two ways: 1) they give too little value to learning strategies that are difficult (using multiple sessions on the big stack), and 2) they give too much credence to strategies that were later documented to be less effective.
The deceptiveness of ease of learning was reinforced in a study reported in Psychological Science by Nate Kornell and collaborators at three other universities. Participants  were asked to predict how easily they would remember vocabulary words after studying them once or multiple times. Some of the words were presented in the standard font size on the person’s computer screen, while others were presented four times larger —something that makes the text feel easier to process but prior research shows does not improve memory. In addition, for some words, participants were told they would be allowed to study more than once.
The participants uniformly predicted that studying the words in larger font would help them remember more than studying the words multiple times. In fact, increased font size did nothing to help them, but studying even once more improved their recall of the new words.
Some school authorities have it all backwards. They want teachers to make the material as easy to learn as possible. I don’t mean to excuse teachers whose instruction is disorganized and confusing. But teachers who challenge students with difficult material and assignments, as well as frequent testing, are actually doing their students a favor. They are just the opposite of the accusation of being “bad” teachers.
This also relates to “dumbing down” the curriculum, which may actually interfere with learning. If we raised standards, we would find that students have to get more engaged. Better learning is  predictable. I think that when learning is difficult, learners are obliged to be more engaged. And it is the engagement that achieves lasting learning. Of course this only works for students who are motivated to learn.

U. S. Students Memorize Too Much?

Making kids memorize too much is the problem with U.S. schools, according to a new movie documentary, "Race to  Nowhere." This movie, produced by a housewife and first-time film maker, is being embraced all across the country by teachers and parents. It is a hot item, especially in New Jersey, where the teacher's union has locked horns with Governor Christi over cost cutting of teacher benefits. Wall Street Journal assistant editor, James Freeman, has done us all a favor by exposing this clap-trap propaganda. Yet this movie is called "a must-see" by the New York Times, an endorsement source that may tell you all you need to know about the movie. Schools, especially in New Jersey, are helping to arrange public showings. Parents, teachers, and educational policy makers are urged to join this propaganda campaign and shown how to do so on the  movie's web site.

But let us examine the premise. Are  students really stressed out by too much memorization? I am not a uninformed housewife. I  have worked with middle-school teachers and their schools for 10 years in developing and deploying science curriculum. I think students are asked to memorize too little, not too much. The movie contends that students don't know much because they are overwhelmed with more material than their little brains can handle. B.S.! I know what state standards require. Trust me, students are not asked to learn too much.

I wrote a book recently, Blame Game, How to Win It (available at Amazon), that focuses on the damaging consequences of misplaced blame. I point out that people make excuses for problems to avoid confronting the pain of dealing with the real causes. The book is not oriented around schools, but it certainly could have been, because schools are prime examples of misplaced blame.

For example, the movie places blame on George Bush for the "No Child Left Behind" (NCLB) law. Many, perhaps most, teachers share in this perverse belief that standards and accountability testing are the cause of poor schools. Nobody wants to remember that schools were just as bad during Jimmy Carter and Bill Clinton eras when there was no NCLB. SAT scores, for example, were just as low then as they are now. The real problem with NCLB is "No Child Pushed Forward." The emphasis in schools I know about is on the lowest common denominator of getting the lowest performing students to meet standards. Students who really care about learning and those who have talent are being cheated by NCLB. We have to rely on the U. S. Army to inspire our kids to "be all they can be."

Progressives also falsely blame insufficient funding for education. The evidence is abundantly clear that there is no correlation between spending per pupil and academic achievement. Time magazine, not noted for conservatism, points out in an article last December that spending on public schools more than doubled in inflation-adjusted dollars between 1970 and 2007. Moreover, up to 44% of school expenditures today are kept "off budget," so the real expenditures are grossly under reported

Few people, especially teachers,  blame the teachers. And few parents or teachers blame the kids. Kids are considered victims of an over-demanding education establishment. Nobody seems to admit that kids might be spoiled with indulgences of all sorts, which includes having their poor performance blamed on anything but them. Anybody who thinks there are not large numbers of lazy, unmotivated kids who are uninterested in learning hasn't been in a classroom lately. Dedicated teachers knock themselves out trying to get such kids up to standard. The problem is not the standards or NCLB.

A lot of kids think they are smarter than they really are. They get this inflated view reinforced from doting parents and anybody over 50 gushing over how smart kids are to multi-task with all their electronic gizmos. I have explained before in earlier posts  that experts have shown multi-tasking to be educationally destructive. Other studies show that kids over-estimate what they know for upcoming tests and undervalue added study.

Here's a paradox. Nobody blinks or complains when school athletic coaches get in the kids' faces to upbraid them when they are being lazy, unmotivated, and under performing. But let a teacher do that and he/she would likely be fired on the spot. Teachers can make excuses for their students. But coaches know that excuse-making won't cut it on the playing field. Why should classrooms be any different?

To return to the point of progressives that school is too hard, I have examined state science standards in great detail because I write middle-school science curriculum. The standards do not demand too much emorization. They don't demand enough, especially the kind of memorization where students have to know how to use knowledge in their thinking. I think that the low-level of memorization required of students today is a main reason why so many students have  under-developed thinking skills. Too many of them mouth platitudes and parrot what others have said. They can't think on their own because they don't know enough to generate original and rigorous thought. Yet, too many educators dismiss the importance of memorization, assuming falsely that kids can think with an empty head. Educators tried that a few years back with "new math," which failed miserably. Now, it appears the same ill-begotten beliefs are re-surfacing in the context of state standards and accountability testing.

Critical and  creative thinking skills are best honed when students are expected to think for themselves, have opinions they can defend with facts and reason, and can persuade others to recognize flaws in their knowledge and thinking. But public schools have a politically correct culture where conformity is valued and individuality is suspect and anti-social. Conformity and tolerance of ignorance and irrationality are considered the virtues to seek, because all belief systems and views are typically considered equivalent (unless they are conservative). Unequal outcomes are just not fair. So standards have to be set low enough so everybody can master them. We therefore don't expect much and we don't get much.

Those who are bent on placing blame on public schools are often looking in the wrong places.Their blame game should target real causes, such as:

  • misguided education professionals
  • dumbed-down curricula and lowered expectations of students
  • teachers who make excuses
  • students and  parents who make excuses
  • political correctness and the philosophy that unequal outcomes are unacceptably unfair
  • devalued memorization. 

Don't hold your breath waiting for any this getting corrected soon. In the meanwhile, urge the kids in your life to read my e-book on learning how to learn: Better Grades, Less Effort, available at Smashwords or Amazon.

A New Way to Fix Ailing Schools

Most people may be tired of hearing about failing schools, because it has been so frustrating trying to get our schools fixed. It’s hard to find any good news about U.S. public schools. Public schools in the U.S. should embarrass us. As arguably the most advanced nation in the world, the U.S. ranks near the bottom of first-world nations in the education of its children.
Examples of student ignorance include survey results showing that two thirds of American teens can’t begin to identify when the Civil War occurred. A poll I read the other day stated that  40% of young adults didn’t know who the U.S. fought in the Revolutionary War! Unbelievably, 20% of students don’t know who the enemies of the U.S. were in World War II. A third do not know that the Bill of Rights guarantees the freedom of speech and religion. Just half know that The Federalist Papers were written to encourage ratification of the U.S. Constitution. The percentage of 17-year-olds who report reading for fun daily declined from one in three in 1984 to one in five in 2004. The middle-school teachers I work with say that most of their students are below grade level in reading.
College students are not impressing either. Less than half of college seniors know that Yorktown was the battle that ended the American Revolution or that NATO was formed to resist Soviet expansion. Overall, freshmen averaged 50.4% on a wide-ranging civic literacy test; seniors averaged 54.2%.
If you are still sanguine about U.S. student competence, you should read Frederick Hess’ book, “Still at Risk. What Students Don’t Know, Even Now.”
So  what’s the fix? Politicians and teacher unions say we don’t spend enough money. They ignore the many formal studies showing there is no correlation between how much money a school district spends and the academic achievement of its students. Nor can money explain this: the  Washington, D.C. school district spends more per student than any district in America, yet its students rank at the bottom. Still not convinced that we spend enough of education? Explain this: cost per pupil, adjusted for inflation, doubled between 1975 and 2005, while test scores remained flat.
There is a new way that is actually the old fashioned way of restoring the pre-eminent role that memorization has in academic success.
I recently read Josh Foer’s provocative new book on memory, “Moonwalking With Einstein.” Foer is a journalist, who once had the same fallible memory as the rest of us until he discovered memorization techniques. He got interested in memory improvement while covering the U.S. Memory tournament. He learned the tricks used by “memory athletes,” and within one year of training, he became the U.S. Champion.
The techniques he learned were not new. They were actually perfected by the poet Simonides and others back in 5th Century B.C. Greece when everything had to be memorized because there were no written places to look up information. These techniques allow “memory athletes” to do such astonishing feats as memorize the precise order of 1,528 random digits in less than an hour  or memorize the sequential order of two decks of cards in less than five minutes. A memory champion from Malaysia memorized the entire 56,000 word, 1,774 page Chinese-English dictionary. Foer himself learned how to memorize the sequence of playing cards in one minute and 40 seconds, setting a U.S. competition record. Foer spent many days visiting with, as well as competing against, these memory athletes. What he learned was that he and the other memory athletes had just average memories when they didn’t use their special techniques.
Memory training can have major impact on school systems.  Foer cites the example of Raemon Matthews, an award-winning teacher in a minority-enrollment vocational high school in South Bronx. His students come from a neighborhood where nine out of ten are below average in reading and math, four out of five live in poverty, and nearly half don’t graduate from high school. Students and visitors entering the building must pass through a metal detector and their bags inspected by a policeman.
Matthews teaches memory techniques. His students stay after school for an extracurricular class in memory. Every class begins with a three-minute memorized recitation. Students memorize every important fact, date and concept in his history class. He requires every essay to contain at least two memorized quotations. A group of his African-American students competes every year in the adult U.S. Memory championships. His corps of elite, all-minority, students have all passed the New York state academic skills test each of the last four years, and 85% of them had a grade of 90 or higher.
Memory techniques obviously increase one’s knowledge. Perhaps even more important, memorization promotes mental  discipline. Kids could use a lot more of both knowledge and mental discipline.
So why don’t we teach memory techniques to school children in every school? Of course, you will say there is no practical reason to  remember long strings of numbers or card sequences like they do in memory tournaments. Even in Vegas, they know how to neutralize card counters. But the principles of memory techniques have great practical value for learning history, math equations, geography, science — anything academic. I had pretty good success academically using these techniques when I was in school, finishing as valedictorian and making A in every class every year since the 6th grade, despite having an IQ only slightly above average. One teacher snorted that I had no right to make such good grades: I was just an over-achiever. This was some 60 years ago when teachers didn’t give away grades to stroke student self-esteem or to avoid whining over grades. The techniques I used in school, plus others I didn’t know about then, are shared in my current e-Book for students, “Better Grades. Less Effort.”
At numerous science teacher meetings over the past four years, I have given presentations on memory principles and techniques in the hope that teachers will teach memorization skills to their students.  But I don’t think I am getting through. Teachers don’t seem to show much interest and the number of e-Book sales is miniscule, despite being priced at a very affordable $2.49 in any format.
I scratch my head in astonishment. I jumped all over these ideas when I was a student. Why don’t others do it?
It could be a combination  of things. For one, we have a progressive educational  culture that regards memorization as old fashioned and out-dated. After all, we can just Google what we want to know.  Nobody seems to believe or understand that a good memory contributes to IQ and thinking productivity. Memory is critical to thinking. You think with what you know and you can’t think in an information vacuum. I doubt that many teachers know that a good memory enhances thinking ability (I have an earlier post on that).  Teacher Matthews is quoted as reminding  us that “You can’t have higher-level learning — you can’t analyze — without retrieving [memorized] information.” He adds, “You can’t learn without memorizing, and if done right, you can’t memorize without learning.”
The educational establishment dismisses Matthews’ philosophy, which they regard as  a conservative throwback to the days when it was standard practice for students to memorize things like the Gettysburg Address, the Bill of Rights, famous poems, and other classics of our cultural heritage. Today, unfortunately, at all levels of the educational system, the role of memory in learning is under appreciated, and even disparaged.
In science teaching, in particular, it is common for teachers to actively disparage memorization. Part of the reason is the long tradition of old-fashioned science teaching in which pointless memorization was demanded of students. I was subjected to a lot of that in my student days: memorizing all the bumps on bones, classification details of plant species, biochemical pathways, and so on. Too much of this still goes on in the college science courses that pre-service science teachers have to take. No wonder so many college students steer away from science. No wonder so many science teachers hate memorization.
The buzz word in science teaching these days is “inquiry.” When I try to tell teachers how important it is to teach kids how to memorize, they look at me as if I don’t understand real science. Pardon me, lady/sir, your ignorance is showing, I AM a scientist. Trust me when I say understanding and knowledge are fundamental pre-requisites to meaningful inquiry. And without knowledge, the results of research are just data.
No, today, we must be progressive, not old-fashioned. Modern educational theory gained traction from the  dominant educational philosopher, John Dewey, who challenged the value of memory, asserting that what is important in education is not knowledge but experience. Currently, mainstream educational theory embraces such attributes as insight, creativity, inquiry learning, and self expression. But these emphases, laudable as they are, lead to a bias against the role of memory in learning.
The bias against memorization may be even worse at the college level. A  faculty colleague chastised me for my emphasis on memorization. This colleague thinks education should be all about understanding and using knowledge to solve problems. We need, he says, to teach students how to think. This colleague is like so many teachers these days who emphasize insight, creativity, inquiry learning, communication skills, and the like without appreciating the role of memory.
I agree wholeheartedly with these higher aims of education. But in the process of educational reform, the progressives discount the importance of memory. Paradoxically, increasing emphasis is being placed on end-of-year high stakes testing, and successful student performance depends heavily on how much they remember from instruction earlier in the year. The teachers I know all complain about having to repeat the same material over and over. They think “one-try” learning is not possible.
My dealings have been with science teachers. They confront another new problem of the fad of “inquiry learning.” Science seems to progressive educators as the natural home for the Dewey’s experiential philosophy. As a successful scientist for over 50 years I can tell you that Dewey certainly did not fully understand science (nor do many teachers today). Science is all about creativity and discovery, but that does not spring from an untutored mind. Creativity comes from a mind that knows, and remembers, a lot.
Consider how Darwin constructed the theory of evolution. He amassed, and remembered, volumes of factual observations over decades, and using this information he was able to put together a coherent theory that had baffled scholars dating back to St. Augustine and earlier. This point is not realized by many science teachers, many of whom teach Creationism instead of the scientific evidence for the origin of species.
In biological sciences, it is no accident many biologists make their most important contributions when they are older, after they have learned a lot. Do you think I could have written this book when I was performing public memory stunts at 16? I may have known the memory  techniques, but did not yet have the knowledge.
Scientific illiterate educators like to point to Einstein who many believe was a poor student. What they apparently don’t know is that when Einstein worked on his research, he was a master learner and memorizer. He read and learned virtually everything written by Newton, Galileo, Bohr, Planck, Doppler, Reimann, Boltzman, Faraday, Maxwell, Poincare, Lorentz, dePretto, Bose, and numerous other scientists over the centuries. He learned Minkowski’s mathematics and curved geometry. He even knew Ben Franklin’s electricity research and cited one of his papers. In short, Einstein’s was so creative because he remembered and built upon the knowledge of numerous predecessors and contemporaries. If he were going to school in 21st century America, the 22nd century world would never hear of Albert Einstein.
Mastering the classical memorization techniques requires creativity. Foer’s book shows how he used creativity to become a memory champion. My book gives other examples of how I used creativity to succeed in school. The ability to be creative requires a “proper inventory, a bank of existing ideas to draw on,” as Foer puts it. The Einstein example above is a classic illustration of the point.
  Another possible explanation for neglect of memory skills is that many people, teachers and students alike, think their memory ability is fixed and can’t be improved. This view is false. Formal studies reveal that people can even increase their working-memory span and in the process increase IQ. Other studies show that students preparing for exams erroneously believe that their performance on the test will not be improved by further study beyond what they think is the best they can do. Also, students know less than they think they know and therefore stop studying for an exam too soon.
Underperforming students have an understandable lack of faith in their academic ability. They don’t try to succeed, because past efforts have failed. They come to believe they are stupid, with mediocrity as their destiny. There is a psychological term for this: learned helplessness.
Teachers need convincing that the more students know, the more they can know. Teacher Matthews makes the point, “Even if facts don’t by themselves lead to understanding, you can’t have understanding without facts.”
Educational fads come and go, yet nothing seems to do much good. Why not try what used to work in education: old fashioned memorization? By the way, the best memorization techniques require learners to think.
