Time capsule: Practical instruction and learn-by-doing pedagogy “strange and alarming”

In November 1936, the March of Time! newsreel introduced the progressive education movement championed by John Dewey as a series of “Strange and alarming teaching innovations which today threaten to change the entire method of public school education in the United States.”

Domesticated gym rats
From “A Wild Workout for the Real World“:
And with that one word — “practical” — Erwan Le Corre [founder of MovNat] exposes a key weakness in modern exercise: Our workouts are domesticated, while the world out there is still plenty wild…
“Being fit isn’t about being able to lift a steel bar or finish an Ironman,” Le Corre says. “It’s about rediscovering our biological nature and releasing the wild human animal inside.“

Babies
The documented first year of four babies in four different corners of the world:
Update: This NYT Magazine story on the moral life of babies is a great complementary reading to the movie:
The mental life of young humans not only is an interesting topic in its own right; it also raises — and can help answer — fundamental questions of philosophy and psychology, including how biological evolution and cultural experience conspire to shape human nature. From Sigmund Freud to Jean Piaget to Lawrence Kohlberg, psychologists have long argued that we begin life as amoral animals. One important task of society, particularly of parents, is to turn babies into civilized beings — social creatures who can experience empathy, guilt and shame; who can override selfish impulses in the name of higher principles; and who will respond with outrage to unfairness and injustice.
A growing body of evidence, though, suggests that humans do have a rudimentary moral sense from the very start of life. With the help of well-designed experiments, you can see glimmers of moral thought, moral judgment and moral feeling even in the first year of life. Some sense of good and evil seems to be bred in the bone. Which is not to say that parents are wrong to concern themselves with moral development or that their interactions with their children are a waste of time. Socialization is critically important. But this is not because babies and young children lack a sense of right and wrong; it’s because the sense of right and wrong that they naturally possess diverges in important ways from what we adults would want it to be.
Trick or treatment
Dr. Harriet Hall has a fascinating article on the placebo effect over at eSkeptic:
We not only know placebos “work,” we know there is a hierarchy of effectiveness:
- Placebo surgery works better than placebo injections
- Placebo injections work better than placebo pills
- Sham acupuncture treatment works better than a placebo pill
- Capsules work better than tablets
- Big pills work better than small
- The more doses a day, the better
- The more expensive, the better
- The color of the pill makes a difference
- Telling the patient, “This will relieve your pain” works better than saying “This might help.”
Dr. Hall also discusses four factors that explain how the placebo effect works — expectancy, motivation, conditioning, and endogenous opiates. Also in the article, a section on whether animals respond to placebos, and a summary of the ethics of the matter.
In this great video, Dr. Ben Goldacre, author of Bad Science, explains the role of the placebo effect in medical research.
Science’s dirtiest secret: The shortcomings of statistics
From an important article and commentary by Tom Siegfried in ScienceNews, the magazine for the Society of Science and the Public:
It’s science’s dirtiest secret: The “scientific method” of testing hypotheses by statistical analysis stands on a flimsy foundation. Statistical tests are supposed to guide scientists in judging whether an experimental result reflects some real effect or is merely a random fluke, but the standard methods mix mutually inconsistent philosophies and offer no meaningful basis for making such decisions. Even when performed correctly, statistical tests are widely misunderstood and frequently misinterpreted. As a result, countless conclusions in the scientific literature are erroneous, and tests of medical dangers or treatments are often contradictory and confusing.

Neuroplasticity 101
GoCognitive produces a great series of videos for educators, researchers, and the general population about a wide variety of topics in cognitive psychology and cognitive neuroscience. Below, “Dr. Ione Fine from the University of Washington explains the basic mechanisms underlying neural plasticity – how the brain can change in response to the specific processing demands of an individual (e.g., by building expertise, after cortical lesions early in life, etc.). The interviewer is Jade Francetich, an undergraduate student of psychology at the University of Idaho.”
This 2003 essay review on the limits of plasticity by Michael S. C. Thomas in the Journal of Cognition and Development makes a great complement to the above video. Abstract:
The more scientists learn about the brain, the more we learn about its infinite plasticity.… If there is a challenge to one part of the brain, we can learn to revive other parts to make all sections of the mind work together. (Elaine Colliar, “mind-mapping” champion, on how a visualization technique might be used to overcome reading impairments in developmental dyslexia; Kenyon, 2002)
We should encourage the public’s interest in developmental brain science and applaud attempts to base early childhood policy and practice on a scientific basis. However, in some instances, public enthusiasm far outstrips our scientific understanding. Too often the messages broadcast by advocates and the media do not accurately reflect what scientists currently knowabout synapses, critical periods, neural plasticity, and how experience affects the brain.

Key takeaways from a fitness trainer
Mike O’Donnell, a professional health and fitness coach, shares insights from his career as a trainer. A sample:
- Pushups are the best upper body workout designed….no machine can replace that…you don’t need any equipment and you can do them anywhere.
- If you eat whole foods that have been around for 1000s of years, you probably don’t have to worry about counting calories.
- If I had to pick one sport for a child to start with it would be gymnastics, the strength/speed/balance/body control they will learn can be applied to any sport down the road.
- I hate to jog…. I love to run.

A missing link in efforts to close the achievement gap

Equity Matters Research Review No. 6
Healthier Students Are Better Learners:
A Missing Link in Efforts to Close the Achievement Gap
NATIONAL–“Healthier Students Are Better Learners“ brings together the most recent findings in fields ranging from neuroscience and child development to epidemiology and public health. Charles Basch focuses on “educationally relevant health disparities” in seven areas — vision; asthma; teen pregnancy; aggression and violence; physical activity; breakfast; and inattention and hyperactivity — that disproportionately affect the educational opportunities and outcomes of urban minority youth. He argues that unless they are addressed in a coordinated fashion at the federal, state and local levels, efforts to close the education achievement gap will be compromised. Nevertheless, he strongly emphasizes that while these seven areas are important, “the expectation is not that every urban public school should have the same priorities,” and priorities may vary according to local need and capacity.

Sexy Gaia
Frank Forencich shares the story of his first “earth orgasm” — a humorous and thoughtful reflection on the sexual energy of mother nature.
For my part, I can vividly recall a number of earth-shattering earth-orgasms, mostly from my days as a climber in the mountains of California. Climbing, like many outdoor sports, is all about getting your body into intimate contact with the natural, tactile world. Exposure promotes vivid sensation, anticipation and engagement. Gravity provides focus and sharpens attention to the here and now. Tactile awareness deepens as fingers and toes probe for subtle variations in form and texture. Skin becomes alert and aware. Every sense comes alive, passionate, desiring ever more. Long summer days of perfect rock, perfect weather, powerful physicality and the sweet caress of a gentle breeze.
There was usually a climax of course, when we reached the safety and panorama of the summit, but this was but a single orgasmic moment surrounded by hours of caress and erotic pleasure. Even the moonlight descent, with our bodies scraped, bruised and fatigued by our efforts, was sensual magic, a feast for eyes, ears and spirit. Only when we reached the highway would the spell be broken.

Picture this: Run hard and get dirty

PatitucciPhoto produces some of the most beautiful and inspiring outdoor sports photography I have ever seen. Check out this collection of trail running pictures.
Also worth browsing — their gallery of images divided into thematic categories for movement, endurance, living, and travel. Via DolomiteSports, you can also view galleries of photographs by activity, such as hiking, road biking, mountain biking, and skiing. It’s enough to make me save for an adventure vacation to the Italian Dolomites.
Shifting the focus from “teaching” to helping students learn
Continuing our discussion about effective teaching (or as my friend Josh Leeger rightly amends, effective communication)…
Eric Mazur‘s engaging talk “Confessions of a Converted Lecturer“ at the University of Maryland on 11 November 2009. The abstract reads: “I thought I was a good teacher until I discovered my students were just memorizing information rather than learning to understand the material. Who was to blame? The students? The material? I will explain how I came to the agonizing conclusion that the culprit was neither of these. It was my teaching that caused students to fail! I will show how I have adjusted my approach to teaching and how it has improved my students’ performance significantly.”

Touched to win—you feel me?
A new study by researchers at U.C. Berkeley has found that the level of physical contact shared among teammates is associated with team success.
In a forthcoming paper to be published by the journal Emotion, psychologists Michael W. Kraus, Cassy Huang, and Dacher Keltner “coded every bump, hug and high-five in a single game by each team in the NBA.” As summarized by the NYT, “good teams tended to be touchier than bad ones… The same was true for players.” Boston Celtics all-star Kevin Garnett, for example, reached out and touched four of his teammates within 600 milliseconds of shooting a free throw. Less productive players rarely initiated physical contact with others.
To correct for the possibility that the better teams touch more often simply because they are winning, the researchers rated performance based not on points or victories but on a sophisticated measure of how efficiently players and teams managed the ball — their ratio of assists to giveaways, for example. And even after the high expectations surrounding the more talented teams were taken into account, the correlation persisted. Players who made contact with teammates most consistently and longest tended to rate highest on measures of performance, and the teams with those players seemed to get the most out of their talent.

A new teaching taxonomy
Doug Lemov, founder of the charter-school network Uncommon Schools, has catalogued 49 clear and specific techniques that promise to improve teacher effectiveness, including:
- The cold call,
- The difference between praise and acknowledgement,
- The use of hand signals to correct behavior, and
- The integration of joyful activities and physical movement into a structured learning environment.
More about Doug’s taxonomy of teaching, classroom management, and the history of teacher education can be found in the NYT Magazine‘s must-read article, “Building a better teacher“:
Among the factors that do not predict whether a teacher will succeed: a graduate-school degree, a high score on the SAT, an extroverted personality, politeness, confidence, warmth, enthusiasm and having passed the teacher-certification exam on the first try.
When Doug Lemov conducted his own search for those magical ingredients, he noticed something about most successful teachers that he hadn’t expected to find: what looked like natural-born genius was often deliberate technique in disguise. “Stand still when you’re giving directions,” a teacher at a Boston school told him. In other words, don’t do two things at once. Lemov tried it, and suddenly, he had to ask students to take out their homework only once.
It was the tiniest decision, but what was teaching if not a series of bite-size moves just like that?
Lemov thought about soccer, another passion. If his teammates wanted him to play better, they didn’t just say, “Get better.” They told him to “mark tighter” or “close the space.” Maybe the reason he and others were struggling so mightily to talk and even to think about teaching was that the right words didn’t exist — or at least, they hadn’t been collected. And so he set out to assemble the hidden wisdom of the best teachers in America.
