Excuse-making by School Children

My last column on "Blaming the Victim" was a departure from my usual emphasis on improving learning and memory. But it did set the stage for this current post on the crippling effect of allowing children to make excuses for underperformance in school.

Most of us know how common it is for kids to make excuses ("the dog ate my homework" syndrome). When we adults were young, we also probably made excuses, blaming the textbook, the teacher, the school, and whatever else could serve to avoid facing the real causes of the problems.

Why do kids do that? The main reason is their fragile egos. Confronting personal weakness is especially hard for kids when they are embedded in an adult culture that inevitably reminds them that they are relatively powerless kids.

I remember a recent dinner-table conversation with my competitive 6th grade granddaughter, who was complaining about a test in which some of the questions were not aligned well with the instruction, which itself was deemed confusing. I said, "I understand that others did do better than you on the test. Wasn't everybody facing the same handicap?" No answer. Then I added, "It doesn't matter who the teacher is or what instruction you get. If you are not first in the class, it is your fault." Again, no response.

One approach that parents and teachers use is to bolster children's egos by praising them richly and often. Too much of a good thing is a bad thing. Too much praise makes kids narcissistic. Anybody who is not aware of the raging narcissism in today's youngsters must not be around young people very much. The most obvious sign is the compulsive checking of e-mail and texting, all in an effort by a child to be at the center of attention.

I and other professors notice narcissism in college students. In a selective college, most students think they are "A" students, and because of low standards in secondary school and grade inflation they are actually told they are A students. If they don't make As in college, it is somebody else's fault (usually the professor).

Scholars are beginning to address this growing narcissism. Eddie Brummelman at the University of Amsterdam in the Netherlands and his colleagues studied 565 children between the ages of 7 to 12. They picked this age group because most other such studies have been in adults, and they believed that early adolescence is when children develop narcissistic traits such as selfishness, self-centeredness and vanity.

Over 18 months, the children and their parents were given several detailed questionnaires that were designed to measure narcissistic traits and parental behavior. There was a small but significant link at each stage between how much parents praised their children and how narcissistic the children were six months later. Because the effect was only small, it suggests that other things also make people selfish and self-centered. I suspect the effect is larger in the U.S.

Maybe school culture is part of the problem. As in Lake Woebegon, "all kids are above average." For brighter students, the instructional rigor is so low that these kids get a false sense of how smart they are and how easy it is to be an "A" student.

I suspect that another factor is that students are not taught enough about how to be realistically self-aware. They may not even know when they are making excuses unless adults call them on it. Too often, parents side with the student in criticizing a teacher when the real problem is with the child.

Some of the blame shifting comes from biology. It is in human nature to claim ownership of things we do that turn out well, but disown actions that yield negative consequences. Experiments support this conclusion. The most recent experiments had a primary focus on our sense of time in association with voluntary actions. The experimental design was based on prior evidence that the perceived estimate of time lag between when we do something and when we think we did it is an implicit index of our sense of ownership. Investigators asked people to press a key, which was followed a quarter of a second later by negative sounds of fear or disgust, positive sounds of achievement or amusement, or neutral sounds. The subjects were then asked to estimate when they had made the action and when they heard the sound. Timing estimation errors were easily measured by computer. Subjects sensed a longer time lag between their actions and the consequences when the outcome (the sound) was negative than when it was positive.

Teaching Kids to Deal with Failure

There is a common denominator to most self-limiting styles of living. It is a fear of failure. Children express this fear by making excuses, which has the unintended effect of blocking the path to success. Excuses may provide immediate relief of anxiety, but it creates a self-limiting learning style that assures continued underachievement.

Whatever one’s station in life, one axiom is paramount: for things to get better for you, you have to get better. This point is well illustrated in an inspiring rags-to-riches success book by A. J. Williams. He points out that a main reason that people do not make the changes they need to is that they are afraid of failure. But, paradoxically, learning from failure is how many people turn their lives around and become happier. Children, I have noticed, are highly resistant to personal change, maybe more so than adults. I am dismayed at how often I show children how to memorize more effectively and they just can't bring themselves to study in a different way. It is as if they don't believe me enough to even try new approaches. Or maybe they have convinced themselves they are mediocre and need the shield of excuses to keep others from detecting their weaknesses.

Louis Armstrong, the famous trumpeter, told an instructive story about fear when he was a boy. One day when his mother asked him to go down to the levee to fetch a pail of drinking water, he came back home with an empty pail. Upon noticing the empty pail, his mother said, “I told you to bring back a pail of water for us to drink. How come your pail is empty?” Louis replied, “There’s an alligator there, and I was scared to death.” His mother then said, “You shouldn’t be afraid. That gator is as afraid of you as you are of him.” To which Louis answered, “If that’s the case, then that water ain’t fit to drink.”

If there is an alligator keeping you away from what you need to do, have faith you will prevail over your demons. But as long as a child lets fear get in the way, her pail will stay empty.

Other kinds of fear are also self-limiting. Many children fear commitment to learning. Commitment exacts an emotional price requiring dedication, passion, and self-discipline. Children fear confusion and difficulty. They fear disapproval.

Kids need to put their under-performance in perspective. Failure and under-achievement are not permanent. They are not pervasive reflections of inadequacy. Children can acquire learning skills that lead to success. Unfortunately, schools don't teach much about learning skills, being focused on teaching to high-stakes tests.

Kids need to recognize their weakness and strive to fix them. But to bolster their motivation and general attitude about school, they need to recognize what they have done well and strive to do even more of that. Dwelling on under-performance is counter-productive.

The Most Important Thing Kids Need to Learn

Excuse-making prevents a child from developing the attitude that will best serve them throughout life: a sense of personal efficacy, a state of perceived control over one's life. I explain this more thoroughly in my book, "Blame Game, How to Win It." But a summary here will have to suffice.

How children perceive their personal power determines how much effort they will expend to control their lives. If they lack a genuine sense of power, excuse-making applies salve to their wounded egos. Self-efficacy is not the same as self-esteem. Psychologist, Albert Bandura, puts it this way: “Perceived self-efficacy is concerned with judgments of personal capability, whereas self-esteem is concerned with judgments of self-worth.” Both are important for happiness, but it is perceived self-efficacy that drives academic achievement. One practical application where this distinction is apparently not recognized is with school teachers who think the cure for low achievement in school is to foster self-esteem. Teachers should emphasize self-efficacy. Children learn self-efficacy from teachers and parents who enable them to master their environment. Students who are filled with self-doubt do not put much effort into school work. They make excuses. As kids are progressively given the skills to achieve, they develop a sense of confidence in their ability to succeed, which will motivate them to strive for more achievement. When I was a kid, I only became a good student when I discovered, more or less by accident, that I could make good grades. Discovering that I could make good grades if I tried motivated me to do just that. This sense has to be earned. It does not come from excuses.

Decision making :learning from one’s mistakes.

Teenagers are notorious for poor decision-making. Of course that is inevitable, given that their brains are still developing, and they have had relatively little life experience to show them how to predict what works and what doesn’t. Unfortunately, what doesn’t work may have more emotional appeal, and most of us at any age are more susceptible to our emotions than cold, hard logic.

Seniors also are prone to poor decision-making if senility has set it. Unscrupulous people take advantage of such seniors because a brain that is deteriorating has a hard time making wise decisions.

In between teenage and senility is when the brain is at its peak for good decision making. Wisdom comes with age, up to a point. Some Eastern cultures venerate their old people as generally being especially wise. After all, it you live long enough, and are still mentally healthy, you ought to make good decisions because you have a lifetime of experience to teach you what future choices are likely to work and which are not.

Much of that knowledge comes from learning from one’s mistakes. On the other hand, some people, regardless of age, can’t seem to learn from their mistakes. Most of the time the problem is not stupidity but a flawed habitual process by which one is motivated to make wise decisions and evaluate options. Best of all is learning from somebody else’s mistakes, so you don’t have to make them yourself.

Learning from your mistakes can be negative, if you fret about it. Learning what you can do to avoid repeating a mistake is one thing, but dwelling on it erodes one’s confidence and sense of self worth. I can never forget the good advice I read from, of all people, T. Boone Pickens. He was quoted in an interview as saying that he was able to re-make his fortune on multiple occasions because he didn’t dwell on losing the fortunes. He credited that attitude to his college basketball coach who told the team after each defeat, “Learn from your mistakes, but don’t dwell on them. Learn from what you did right and do more of that.”

It would help if we knew how the brain made decisions, so we could train it to operate better. “Decision neuroscience” is an emerging field of study aimed at how learning how brains make decisions and how to optimize the process. Neuroscientists seemed to have honed in on two theories, both of which deal with how the brain handles the processing of alternate options to arrive at a decision.

One theory is that each option is processed in its own competing pool of neurons. As processing evolves, the activity in each pool builds up and down as each pool competes for dominance. At some point, activity builds up in one of the pools to reach a threshold, in winner-take-all fashion, to allow the activity in that pool to dominate and issue the appropriate decision commands to the parts of the brain needed for execution. As one possible example, two or more pools of neurons separately receive input that reflects the representation of different options. Each pool sends an output to another set of neurons that feed back either excitatory or inhibitory influences, thus providing a way for competition among pools to select the pool that eventually dominates because it has built up more impulse activity than the others.

The other theory is based on guided gating wherein input to pools of decision-making neurons is gated to regulate how much excitatory influence can accumulate in each given pool. [i]The specific routing paths involve inhibitory neurons that shut down certain routes, thus preferentially routing input to a preferred accumulating circuit. The route is biased by estimated salience of each option, current emotional state, memories of past learning, and the expected reward value for the outcome of each option.

These decision-making possibilities involve what is called “integrate and fire.” That is, input to all relevant pools of neurons accumulates and leads to various levels of firing in each pool. The pool firing the most is most likely to dominate the output, that is, the decision.

However circuits make decisions, there is considerable evidence that nerve impulse representations for each given choice option simultaneously code for expected outcome and reward value. These value estimates update on the fly. Networks containing these representations compete to arrive at a decision.

Any choice among alternative options is affected by how much information for each option the brain has to work on. When the brain is consciously trying to make a decision, this often means how much relevant information the brain can hold in working memory. Working memory is notoriously low-capacity, so the key becomes remembering the sub-sets of information that are the most relevant to each option. Humans think with what is in their working memory. Experiments have shown that older people are more likely to hold the most useful information in working memory, and therefore they can think more effectively. The National Institute of Aging began funding decision-making research in 2010 at Stanford University’s Center on Longevity. Results of their research are showing that older people often make better decisions than younger people.

As one example, older people are more likely to make rational cost-benefit analyses. Older people are more likely to recognize when they have made a bad investment and walk away rather than throwing more good money after bad.

A key factor seems to be that older people are more selective about what they remember. For example, one study from the Stanford Center compared the ability of young and old people to remember a list of words. Not surprisingly, younger people remembered more words, but when words were assigned a number value, with some words being more valuable than others, older people were better at remembering high-value words and ignoring low-value words. It seems that older people selectively remember what is important, which should make it easier to make better decisions.

Decision-making skills are important of learning achievement in school. Students need to know how to focus in general, and focus on what is most relevant in particular. They are not learning that skill, and their multi-tasking culture is teaching them many bad habits.

Those of us who care deeply about educational development of youngsters need to push our schools to address the thinking and learning skills of students. "Teaching to the test" detracts from time spent in teaching what matters most. Today's culture of multi-tasking is making matters worse. Children don't learn how to attend selectively and intensely to the most relevant information, because they are distracted by superficial attention to everything. Despite their daily use of Apple computers and smart phones, only one college student out of 85 could draw the Apple logo correctly.[iii]

Memory training is generally absent from teacher training programs. Despite my locally well-publicized experience in memory training, no one in the College of Education at my university has ever asked me to share my knowledge with their faculty or with pre-service teachers. The paradox is that teachers are trained to help students remember curricular answers for high-stakes tests. What could be more important than learning how to decide what to remember and how to remember it? And we wonder why student performance is so poor?

What Happened to The Wonder of Learning?

I read a lot about educational theory and research so that I can share "best practices" for better ways to teach and learn with my readers. Shared here are the ideas in a most informed and intelligent article on learning, written by Catherine L'Ecuyer, a Canadian lawyer with an MBA now living in Barcelona, Spain.[1]The article explains the fundamental importance for motivating children to learn: the sense of wonder.

This notion resonated with me, because I know it to be true from personal experience. To this

day, I have vivid memories of the excitement I had as a six-year old in Fort Myers, Florida, as I walked to my first day of school. Yes, in those days it was safe for kids to walk several blocks to school unattended. And yes, there was, at least for me, no kindergarten, pre-kindergarten, or day care.

Sauntering to school, I became entranced with all the new sights and sounds, stopping several times along the way to savor a new experience. A vivid memory was my stop at a beautiful flower I had never seen before. I physically probed the bloom, astonished at the elegant expression of nature. On that day, the prospect of school was a most joyous opportunity. It did not take long for school's pedantic nature, drills, and drudgery to squelch my sense of wonder. It was only in late middle school that my sense of wonder was resurrected, and that only occurred because I had a crush on my teacher and wanted to impress her with my learning. For many children, their inherent sense of wonder that school stamps out never returns.

Clearly, a child's state of mind affects how learning and the school environment are regarded. Among the more relevant states is stimulus seeking. That is why for example I wanted to explore the innards of that beautiful flower. Then too, there is the basic human responsiveness to positive reinforcement. If a learning experience is perceived as wondrous, it is perceived as good and beneficial, serving as incentive to have other such learning experiences. It obviously helps for a child to be aware of such perceptions.

L'Ecuyer adds the sense of wonder to the list of fundamentals of the motivation to learn. She makes the point that wonder is innate in children, especially when they are young. As a child matures, much of this sense of wonder can fade. For some people, the more they learn, the less wondrous the world seems. Among adults, scientists seem to be an exception (to a biologist, pond scum is beautiful and wondrous).

L'Ecuyer argues that modern educational paradigms are behaviorist and conflict with nurturing the sense of wonder in children. By behaviorist, she means that the guiding principle of teaching is that the environment directs learning with its emphasis on teachers, curriculum, and high-stakes testing. The popular mantra is that learning is better when it is provided earlier and in abundance. Curricula are designed to bombard students with information and testing. Do we really think that is motivating?

The problem is that children can be overwhelmed by too much too soon. Yet government policy increasingly advocates pre-kindergarten. Young developing brains do not respond well to too much stimulus, too much curriculum, and too much high-stakes testing. Children become preconditioned to expect high levels of stimulation, leading to attentiveness disorders. Children become passive and bored. The associated loss of the sense of wonder diminishes a child's motivation to cope with all this stimulus and pressure.

L'Ecuyer cites convincing research showing that compared to adults children learn at a slower pace than adults. They need more calm and silence. They are more intrigued by mystery. They need to trust in a human attachment figure, most commonly a caring mother.  Unfortunately, our educational culture assumes that we don't teach enough curriculum and don't demand enough of children. Children learn to pass tests, not love learning. Our multi-tasking culture only adds to sensory and cognitive overload that interferes with learning and mental performance in general. The family breakdown in our culture diminishes a child's trust in primary caregivers and degrades attachment to them. Schools cannot provide such trust and attachment. Nor can pre-kindergarten or day-care.

These are basic reasons why I push for a reform in education that stresses teaching learning skills to young children, as opposed to the domination of traditional curriculum and excessive high-stakes testing. I am writing such a book now. When children have good learning skills, learning stops being an onerous chore. The "Learning Skills Cycle" that I advocate begins with motivation, and motivation begins with a sense of wonder.[2]

Educational policy makers seem confused about why so many students fall behind. Every year, over 1.2 million students drop out of high school in the United States. That’s a student every 26 seconds – or 7,000 a day. About 25% of high school freshmen fail to graduate from high school on time.[3]At the college level, only 59% of full-time four-year college students graduate within six years.[4]Most college data use a six-year limit because so many college students can't finish in the usual four years.

Over the last 40 years, all the educational fads we have tried apparently do not work. In this time we have had such high-profile government initiatives as "Goals 2000, New Math, Nation at Risk, No Child Left Behind, Race to the Top, Common Core, Next Generation Science Standards, Charter Schools, and Head Start." Where is the evidence that any of this works? SAT scores have not improved, even declining in some years, while funding for educational has increased dramatically, on the order depending on the state of 200%.[5]

Despite much ballyhoo and funding, Head Start's effects wash out within a few years. Nonetheless, many states think Head Start did not start early enough and that what is needed is government funded pre-kindergarten. Nobody considers what this too-soon, too-much, too stressful education does to childhood sense of wonder and motivation to learn.

The key question asked by L'Ecuyer is this: Are today's educational paradigms and policies promoting the sense of wonder and motivation to learn or squelching it? While all our government programs to improve education seem valuable, the results say otherwise. Teaching is now driven by high-stakes testing. While accountability is necessary, when high-stakes testing becomes the focus of education, it poisons the learning atmosphere. The law of unintended consequences applies. Today's educational environment suffocates the wonder and love of learning for its own sake.

Study Smart Beats Study Hard

Keep your "nose to the grindstone" is the advice we often tell young people is an essential ingredient of learning difficult tasks. A joke captures the matter with the old bromide for success, "Keep your eye on the ball, your ear to the ground, your nose to the grindstone, your shoulder to the wheel: Now try to work in that position."

Over the years of teaching, I have seen many highly conscientious students work like demons in their study yet don't seem to learn as much as they should for all the effort they put in. Typically, it is because they don't study smart.

In an earlier post, I described a learning strategy wherein a student should spend short (say 15-20 minutes) of intense study followed immediately by a comparable rest period of "brain-dead" activity where they don't engage with intense stimuli or a new learning task. The idea is that during brain down-time the memory of just-learned material is more likely to be consolidated into long-term memory because there are no mental distractions to erase the temporary working memory while it is in the process of consolidation.

Now, new research suggests that too much nose-to-the-grindstone can impair learning. Margaret Schlichting, a graduate student researcher, and Alison Preston, an associate professor of psychology and neuroscience at the University of Texas tested the effect of mental rest with a learning task of remembering two sets of a series of associated photo pairs.  Between the two task sets, the participants rested and were allowed to think about whatever they wanted. Not surprisingly, those who used the rest time to reflect on what they had just learned were able to remember more upon re-test. Obviously, in this case, the brain is not really resting, as it is processing (that is, rehearsing) the new learning. But the brain is resting in the sense that new mental challenges are not encountered.

The university press release quotes the authors as saying, "We've shown for the first time that how the brain processes information during rest can improve future learning. We think replaying memories during rest makes those earlier memories stronger, not just impacting the original content, but impacting the memories to come." Despite the fact that this concept has been anointed as a new discovery in a prestigious science journal, the principle has been well-known for decades. I have explained this phenomenon in my memory books as the decades-old term of "interference theory of memory,"

What has not been well understood among teachers is the need to alter teaching practices to accommodate this principle. A typical class period involves teachers presenting a back-to-back succession of highly diverse learning objects and concepts. Each new topic interferes with memory formation of the prior topics. An additional interference occurs when a class period is disrupted by blaring announcements from the principal's office, designed to be loud to command attention (which has the effect of diverting attention away from the learning material). The typical classroom has a plethora of other distractions, such as windows for looking outside and multiple objects like animals, pictures, posters, banners, and ceiling mobiles designed to decorate and enliven the room. The room itself is a major distraction.

Then, to compound the problem, the class bell rings, and students rush out into the hall for their next class, socializing furiously in the limited time they have to get to the next class (on a different subject, by a different teacher, in a differently decorated classroom). You can be sure, little reflection occurs on the academic material they had just encountered.

The format of a typical school day is so well-entrenched that I doubt it can be changed. But there is no excuse for blaring loudspeaker announcements during the middle of a class period. Classrooms do not have to be decorated. A given class period does not have to be an information dump on overwhelmed students. Short periods of instruction need to be followed by short, low-key, periods of questioning, discussion, reflection, and application of what has just been taught. Content that doesn't get "covered" in class can be assigned as homework—or even exempted from being a learning requirement. It is better to learn a few things well than many things poorly. Indeed, this is the refreshing philosophy behind the new national science standards known as "Next Generation Science Standards."

Give our kids a rest: the right kind of mental rest.

Grit's Role in Learning

What do you think is the major determinant of whether our children excel in school? IQ? Good teachers? Good schools? Good standards and curricula? No, I say it is the students' motivation, or just plain grit. Other teachers think so too.

Education reporter, Libby Nelson, calls attention to the issue of grit in student learning achievement. Teachers and parents sometimes put too much emphasis on intelligence, when the more typical problem in education is that students don't try hard enough and are not sufficiently persistent in trying to achieve excellence.

Indeed, excellence is not even a goal for most students. Many students just want to do the minimum required to pass tests. A few students don't care at all. They just drop out. One student told a teacher friend of mine, "I don't need to learn this stuff. Somebody will always take care of me."

Nelson points to evidence of grit's importance with these examples:

·         West Point cadets who scored highest on a scale of grit were more likely to complete the grueling first summer of training.

·         National spelling bee contestants with more grit ranked higher than other contestants of the same age who had less grit.

·         College admissions officers know how important grit is (more important than SAT tests) but they don't know how to measure it other than grades, which of course may be inflated and inaccurate indicators of grit.

Clearly motivation is essential. I regard motivation as the cornerstone of what I call the "learning skills cycle." Learning begins with being motivated to learn, and successful completion of every step in the cycle strengthens motivation. However, every step in this cycle (organization, attentiveness, understanding/synthesis, memory, and problem solving/creativity) requires a degree of grit—the more, the better.

As applied to specific learning tasks, grit is central to all the ideas in the learning skills cycle. In the case of memory, for example, the well-known strategy of deliberate practice requires disciplined grit. Students diligently need to use established memory principles in a systematic way. This includes constructing a systematic learning strategy that includes organizing the learning materials in an effective way, intense study focus in short periods, elimination of interferences, use of mnemonic devices, and frequent rehearsals repeated in spaced intervals. Learning success depends on mental discipline and persistence.

Students differ enormously in their level of grit. It would be nice if we knew how to teach grit. Surely, parental influence is central. Parents lacking in grit are unlikely to model or teach it to their children. Some schools, especially private schools, teach grit by having high expectations and programs that help students discover the positive benefits that come from having more grit. One of those benefits is confidence, because grit promotes achievement and achievement develops confidence.

Confidence in the ability to learn is necessary for a student to try hard to learn. Here is the area where teaching skills count most: showing students they can learn difficult material and thereby building the confidence to take on greater learning challenges.

Students who have passionate goals are much more likely to invest effort and persistence in doing what is needed to achieve those goals. It is unrealistic to expect grade-school children to have well-formulated career goals. But certainly by early high-school, students should be forming specific lifetime goals. What a career goal is probably does matter as much as having one in the first place. Achieving a goal, regardless of whether it is later abandoned or not, teaches a youngster that grit is necessary for the achievement. The student learns that grit has a payoff.

Grit may not always lead to excellence in students with innate limited abilities. But grit allows such students to "become all they can be," as the Army recruitment slogan claims. Moreover, the benefits of grit perpetuate beyond success at any one learning challenge. Learning anything requires physical and chemical changes in the brain needed to store the positive attitudes that come from learning success and the learning content itself. In other words, the more you know, the more you can know.

How Schools Make Learning Harder Than Necessary

Keep your "nose to the grindstone" is the advice we often give as an essential ingredient of learning difficult tasks. An old joke captures the problem with the old bromide for success, "Keep your eye on the ball, your ear to the ground, your nose to the grindstone, your shoulder to the wheel: Now try to work in that position."

Content that doesn't get "covered" in class can be assigned as homework—or even exempted from being a learning requirement. It is better to learn a few things well than many things poorly. Indeed, this is the refreshing philosophy behind the new national science standards known as "Next Generation Science Standards."

Give our kids a rest: the right kind of mental rest.
