Teach More, Learn More, less sleep and back and shoulder pain

Insightful article I obtained from my teacher's facebook entry...

Don't read if you are rushed for time...

There are two interesting reports about Singapore’s students in Singapore’s main newspaper, the Straits Times, on 5 January 2009. The first report focuses on the sleeping patterns of Singapore’s teenagers. The second report is about the effect of heavy school bags that Singapore students carry to school.

The first report says that four in five of Singapore’s teenagers are not getting enough sleep. The average teenager is supposed to get more than eight to nine hours of sleep. According to the report half of those studied actually had only five to six hours of sleep.

Although the report did mention that one of the reasons for the lack of sleep among teenagers is because they chat online, it is also disturbing to read that many of these teenagers who lack sleep are high-achievers in school who believe that they can do without the recommended amount of sleep.

According to Dr Lim Li Ling, director of the Singapore General Hospital’s Sleep Disorder Unit:

“Some proudly let me know that they sleep only four hours a night. It’s not something they should feel proud about. It affects their brain potential - how much they can learn and consolidate.”

A study in the United States has shown that teenagers who are top students do even better with sufficient sleep. The report also says that the heavy school load and co-curricular activities are additional reasons for the teenagers’ lack of sleep.

We can infer from this report that the examination-centered Singapore school curriculum is clearly an important reason for this sleep deprivation with its long term health consequences. One also wonders about the mental health of these students.

The second report focuses on a study by Singapore’s Republic Polytechnic on the effect of a heavy school bags on Singapore’s students. The study done by Dr Michael Koh and Mr Tarkeshwar Singh of the Republic Polytechnic. They found that Singapore’s students tend to take shorter, quicker steps to offset the typically heavy loads that they carry to school. According to the report the changes in gait will not reduce the problems these students will face with regards to their posture, or their joints and ligaments which can lead to back and shoulder pains.

Another doctor, Dr Kevin Lim, an orthopaedic consultant at the KK Women’s and Children’s Hospital in Singapore, says that he treats up to five to ten children every week for such pains. The report says this is despite schools in Singapore now providing lockers for the students.

In case you are wondering why the locker solution has not worked, it is probably because parents and the schools themselves still insist that these students bring their text books and other accessories home so they can still use them for even more studying back home. One solution to this problem is to buy extra copies of text books; one set for home use and one set for the school. Quite a few parents have resorted to this which explains the perennial shortage of text books even before the new school calendar begins. But this applies only to those parents who can afford two sets of books!

The other reason is that for each subject there is usually a text book, activity or work book, plus the books for writing. Seldom is the student told which of these books are required for the next day of school. In fact, many teachers just insist that students bring all their books for the subjects. Multiply the number of books for each subject by the number of subjects each day (which is at least four each day). That will give you an idea of the load. Don’t forget also the stacks of printed notes and worksheets given to the students by the teachers. This is how Singapore students do well in examinations and TIMSS!

When schools in the neighboring countries like Indonesia, Vietnam and China seek the Singapore school model for themselves, I wonder how many of these schools go beyond Singapore school’s excellent examinations performance and TIMSS results when they choose the Singapore school model? What price are parents in these countries willing to pay for “educational” success with their children’s long term health? It is clear from these two reports that the Singapore education system breeds success at the expense of the students’ health. This is a natural effect of the schools’ heavy load and the pressure to excel in the high stakes examinations.

Lastly, one wonders about the state of the teachers in Singapore’s schools. With the teaching and preparation that they have to do to meet the targets set for the high stakes examinations , the large class sizes and the accompanying heavy marking load, we wonder about the state of physical and mental health these teachers are in. So much for the “Teach Less, Learn More” (TLLM) initiative of the Ministry of Education (MOE).

Job Credits

For the past decade, the government has emphasized creative thinking in schools, today it has walk the talk by introducing a new measure known as "Job Credits" in its latest budget to fight the recession.

Job Credits is set to become the new buzzword in economics in a few years' time. This innovative measure introduces a fresh approach to retaining jobs in an economy and is an out-of-the-box measure never before implemented by any country. The idea is that the government would hand out "credits" or rebates to companies and the size of the 'credit' would depend on the number of workers the firm employs. For each worker employed, the firm gets a 12% rebate on the wage of the worker. The credits would be handed out every 3 months or 4 times a year. This innovative approach contributes directly to the government's aim of protecting the jobs of Singaporeans.

I must say that this time round I am impressed by the quality of the solution conceived by the budget team. It's something that is simple, to the point and effective in achieving its objective.

An Economy of Faith and Trust

Got this from my lecturer.

Quoted from http://www.nytimes.com/2009/01/16/opinion/16brooks.html?_r=1&partner=permalink&exprod=permalink&pagewanted=print.

Once there was just Newtonian physics and the world seemed neat and mechanical. Then quantum physics came along and revealed that deep down things are much weirder than they seem. Something similar is now happening with public policy.

Once, classical economics dominated policy thinking. The classical models presumed a certain sort of orderly human makeup. Inside each person, reason rides the passions the way a rider sits atop a horse. Sometimes people do stupid things, but generally the rider makes deliberative decisions, and the market rewards rational behavior.

Markets tend toward efficiency. People respond in pretty straightforward ways to incentives. The invisible hand forms a spontaneous, dynamic order. Economic behavior can be accurately predicted through elegant models.

This view explains a lot, but not the current financial crisis — how so many people could be so stupid, incompetent and self-destructive all at once. The crisis has delivered a blow to classical economics and taken a body of psychological work that was at the edge of public policy thought and brought it front and center.

In this new body of thought, you get a very different picture of human nature. Reason is not like a rider atop a horse. Instead, each person’s mind contains a panoply of instincts, strategies, intuitions, emotions, memories and habits, which vie for supremacy. An irregular, idiosyncratic and largely unconscious process determines which of these internal players gets to control behavior at any instant. Context — which stimulus triggers which response — matters a lot.

This mental chaos explains how people can respond so quickly and intuitively to so many different circumstances. But it also entails a decision-making process that is more complicated and messy than previously thought.

For example, we don’t perceive circumstances objectively. We pick out those bits of data that make us feel good because they confirm our prejudices. As Andrew Lo of M.I.T. has demonstrated, if stock traders make a series of apparently good picks, the dopamine released into their brains creates a stupor that causes them to underperceive danger ahead.

Biases abound. People who’ve been told to think of a high number will subsequently bid much more for an item than people who’ve been told to think of a low number. As Jonah Lehrer writes in his forthcoming book, “How We Decide,” there are certain circumstances (often when there are many options) in which gut instincts lead to the best decisions, while there are other circumstances (sometimes when there are a few options) when calm deliberation is best.

Most important, people seek relationships more than money. If behaving a certain way helps a stock trader or a regulator fit in with his crowd, he’s likely to keep doing it without too much rigorous self-examination.

A thousand mental shortcomings contributed to the financial meltdown. Republicans have tried to explain it by pointing to irresponsible policies at Fannie Mae. But that only explains a piece of what’s happening.

This crisis represents a flaw in the classical economic model and its belief in efficient markets. Republicans haven’t begun to grapple with the consequences.

For years, Republicans have been trying to create a large investor class with policies like private Social Security accounts, medical savings accounts and education vouchers. These policies were based on the belief that investors are careful, rational actors who make optimal decisions. There was little allowance made for the frailty of the decision-making process, let alone the mass delusions that led to the current crack-up.

Democrats also have an unfaced crisis. Democratic discussions of the stimulus package also rest on a mechanical, dehumanized view of the economy. You pump in a certain amount of money and “the economy” spits out a certain number of jobs. Democratic economists issue highly specific accounts of multiplier effects — whether a dollar of spending creates $1.20 or $1.40 of economic activity.

But an economy is a society of trust and faith. A recession is a mental event, and every recession has its own unique spirit. This recession was caused by deep imbalances and is propelled by a cascade of fundamental insecurities. You can pump hundreds of billions into the banks, but insecure bankers still won’t lend. You can run up gigantic deficits, hire road builders and reduce the unemployment rate from 8 percent to 7 percent, but insecure people will still not spend and invest.

The economic spirit of a people cannot be manipulated in as simple-minded a fashion as the Keynesian mechanists imagine. Right now political and economic confidence levels are running in opposite directions. Politically, we’re in a season of optimism, but despite a trillion spent and a trillion more about to be, the economic spirit cowers.

Mechanistic thinkers on the right and left pose as rigorous empiricists. But empiricism built on an inaccurate view of human nature is just a prison.

Office Politik

It is with sadness that i realize that office politics exists in every work environment. As long as you work in an office, you cannot escape from it.

Recently, I thought that I had found an ideal working environment where there is no office politics and colleagues help one another out. I was wrong. Every moment we are watched and observed by others in the office. Regardless of whether we like it or not, we are constantly being monitored by others. Consciously or sub-consciously, judgements are being passed.

When you think all went well and you have a rare harmonious working relationship with your colleague, your boss informs you that one of your colleagues has 'commented' that you are chatting with people more than you should; that you should probably work harder because everyone else is working hard.

It gets depressing. It is one fact of life that you thought you have heard about and accepted. Sadly, acceptance only comes about when you have experienced it yourself.

The need to portray that you are always working hard during office hours is ever present. The constant need to maintain a certain image is always there. The constant need to cover your back is always there. Now i understand why people say that you wear a mask to work every day. Everyone does... It's hard to forge close friendship in an office. That's why secondary school and junior college school days are memorable.

Uncle Sam is watching......

Bad Relief Teaching Experience

Someone asked why I had joined teaching. I did not join because I had some wonderful or memorable relief teaching experience. In fact, I had quite a negative experience while relief teaching.

I ORD-ed in March, so I wasn't able to get any long term relief teaching assignment. I got placed in the reserve list. Only if a teacher was on MC, would I get a call in the morning to go do relief teaching. It was that ad-hoc.

I got called up to do relief teaching at a neighbourhood secondary school in the west. The first class was a Normal (Academic) Sec 2 class. They were supposed to have Arts lesson, so I brought them to the Arts room. A guy and a girl started to quarrel. The guy called the girl a pig and the girl was unhappy. She went to the sink and filled a container with water. She went on to splash the water at the guy. But the water did not hit the guy; instead it landed on me who was trying to break up the fight. I remarked: "So you are happy now?" Then the two of them went back to their seats and the class was quiet for the next two period. Well~ At least they were quiet. Small sacrifice on my part -- my shirt was totally wet.

After that, I went to stand in for a Sec 3 Express class. They were very noisy and I had no way of making them silent. A girl came up to me and asked: "Teacher, can i stamp you?" She was holding a stamp in her hand. You know, the type that teachers used to stamp stars on our assignments when we were young. The ink stamp. Of course, I replied: "No, you can't." Then i went to do my rounds in the class to ask them to lower their volume. The girl followed behind and stamped me on my back.

"What are you doing!"

I was irritated.

"Stamping you lor!" she replied calmly.

I didn't know whether to laugh or to cry.

Yup~ Just two of the more memorable traumatic experiences I had while relief teaching.
