Most classroom learning sucks

Excerpt from:

Creating Passionate Users: Most classroom learning sucks
The most depressing result of Skyler’s transition to public school was when she came home one day a few weeks into her 7th grade, and said, “In real school, they don’t seem to like it when you question the teacher…” She was horrified to be labeled somewhat of a troublemaker, because she’d been treated for so many years as a thinking person, encouraged to challenge and question and not assume it was her fault if she didn’t understand something. Suddenly dropped into the US public school system, she quickly learned that it’s a very different world. She knew more about learning theory and the brain than most of her school’s administration, and her tolerance for poor/weak educational experiences was pretty low.

She did have some fabulous teachers throughout the rest of her public school days, but wouldn’t you know it–they were always the teachers getting into trouble with the school administration or even parent’s groups. In a later post I’ll tell you a shocking story about one of her teachers who made the national news, twice, for encouraging students to think–and act– for themselves. He was nearly fired during a witch hunt that both local and national media seized on (although most later offered apologies when it became obvious what was really going on).

Learning doesn’t happen in the middle!

10-Jan-2005 By Jim

Filmmakers know that the feeling the audience leaves with has a huge impact on the movie’s success. It’s what the audience remembers, and determines how (and whether) they talk about the movie to others. When filmmakers do audience testing, they’re trying to get the ending right, and that’s why usually the best music of the movie is saved for the ending credits.

It’s the psychological princple known as primacy-recency, and it matters to advertisers, writers, entertainers, and teachers.

Beginnings

When it comes to retention and recall, the middle sucks.

People tend to remember beginning and endings better than middles.

So the solution is simple: have more beginnings and endings in your message.

A 90-minute lecture with no breaks means that most of the material is presented somewhere in the vast cognitive wasteland of the middle.

A series of 15-minute mini-lectures punctuated by exercises for deeper processing of the new content, means a lot more beginnings and endings, so more opportunities for better learning, especially better recall and retention.

The more granular the message “chu

Circadiana: Everything You Always Wanted To Know About Sleep (But Were Too Afraid To Ask)

08-Jan-2005 By Jim

Excerpt from:
Circadiana: Everything You Always Wanted To Know About Sleep (But Were Too Afraid To Ask)
Until not long ago, just about until electricity became ubiquitous, humans used to have a sleep pattern quite different from what we consider “normal” today. At dusk you go to sleep, at some point in the middle of the night you wake up for an hour or two, then fall asleep again until dawn. Thus there are two events of falling asleep and two events of waking up every night (plus,
perhaps, a short nap in the afternoon). As indigenous people today, as well as people in non-electrified rural areas of the world, still follow this pattern, it is likely that our ancestors did, too.The bimodal sleep pattern was first seen in laboratory animals (various birds, lizards and mammals) in the 1950s, 60s and 70s, i.e, before everyone moved their research to mice and rats who have erratic (un-consolidated) sleep patterns. The research on humans kept in constant conditions, as well as field work in primitive communities (including non-electrified rural places in what is otherwise considered the First World) confirmed the bimodality of sleep in humans, particularly in winter.

Popping melatonin pills is one of the latest crazes. Melatonin failed as a sleeping pill and its uses as a scavenger of free radicals are dubious at best. It can shift one’s clock, though (rebeldoctor.blogspot.com…). However, it cannot help against jet-lag or effects of shift-work (shift-lag) as melatonin is likely to shift only the main brain pacemaker in the suprachiasmatic nuclei. The problem with jet-lag and shift-lag is dissociation of rhythms between cells in different tissues, i.e., your brain clock may resynchornize to the new time-zone/schedule in a couple of days, the clocks in your heart and lungs in a week, and in your stomach and liver in a month. In the meantime, everything in your body is desynchronized and you feel really bad. If you keep changing your work shift over and over again, you never get to achieve complete synchronization, leading to long-term effects on health, including significant rise in heart attacks, stomach ulcers, and breast cancer.

Well, intercontinental flight is here to stay, and some shift-work is neccessary for the modern society to survive. It is now understood that some people (chronotypes) adjust to night-shifts and even properly executed (non-rapid, phase-delaying) rotating shifts, better than others. People have always tried to self-select for various schedules, yet it has recently started to enter the corporate consciousness that forcing employees into unwanted shifts has negative effects on productivity and safety, thus bottom line. See Chernobyl, Bhopal, Exxon Valdese and Three Mile Island accidents – all caused by sober but sleepy people at about 3am, just like thousands of traffic accidents every year.

TSUNAMI — Delivering aid stymies UN

08-Jan-2005 By Jim

National Business Review (NBR) – Business, News, Arts, Media, Share Market & More
While the United Nations appears to be adept at having meetings, the organisation is hopeless on the ground say career foreign service officers in tsunami-affected regions.

As news media are increasingly dominated by footage of US, Australian and regional military forces actually delivering aid to stricken survivors of the Boxing Day tsunami, UN officials are carping about housing in major cities far removed from the front lines and passing around elaborate business cards.

Organising to organise seems to be the word of the day for the UN, say career US foreign service officers anonymously, who fault the international organisation for taking credit where none is due and proving hopeless at actually delivering relief.

A blog (The Diplomad) run by “career US Foreign Service officers” — many serving in what they call the “Far Abroad” as a eupehmism for what appears, often, to be Sri Lanka — is loading the internet with accounts of UN ineptitude in the wake of the tsunami disaster.
