Impact of Sleep on Learning and Weight

UCLA researchers found that children who don't get enough sleep might wind up with an overweight body. Looking at sleep patterns of 1,900 children between the ages of 1 and 13, they found that children maintaining less than 10 hours of sleep a night had an 80% more probability of being obese. The study furthermore found that naps during the day did not offset the effect. The believe is that a lack of nighttime sleep throws off key hormones that affect weight and metabolism.

So how much sleep is needed per 24 hours?
Birth - 2 months: 12 - 18 hours
3 - 11 months: 14 - 15 hours
1 - 3 years: 12 - 14 hours
3 - 5 years: 10 - 11 hours
10 - 17 years: 8.5 to 9.5 hours
Adults: 7 - 9 hours
Insufficient sleep is also associated with chronic diseases such as diabetes, cardiovascular disease, and depression. The promotion of regular sleep is referred to as 'sleep hygiene'. Here are some simple sleep hygiene tips:

• Go to bed at the same time each night, and rise at the same time each morning.
• Sleep in a quiet, dark, and relaxing environment, which is neither too hot nor too cold.
• Make your bed comfortable and use it only for sleeping and not for other activities, such as reading, watching TV, or listening to music.
• Remove all TVs, computers, and other "gadgets" from the bedroom.
• Avoid physical activity within a few hours of bedtime.
• Avoid large meals before bedtime.

Dance and Core Academics

In an April 2011 speech, Secretary of Education, Arnie Duncan made the point that "for decades, arts education has been treated as though it was the novice teacher at school - the last hired and the first fired when times get tough". He was echoing a sentiment of many prominent educators who have championed the inclusion and/or expansion of arts in schools. Dance in particular has suffered as the smallest of the four art forms.

But that is changing. EdWeek reported on an elementary school in Maryland where students execute dance movements to simulate the elements of photosynthesis, including water, sunlight, carbon dioxide, and chlorophyll. They leaned, reached, and flowed with surprising grace. Want to bet that the retention and understanding of this lesson is much higher?

And that is the point. Cross curriculum or mutual learning takes place when core subjects are matched with rhythm and movement. GeoMotion, a company based in Orlando, FL, has developed a mat with numbers on it. By following the numbers and directional ques, students integrate math and other core subjects while working out. Their 'Meaningful Movement' program is based on integrated learning and it makes sense - it addresses all the levels of optimal learning to include:

• Rhythmical / Musical
• Visual / Spatial
• Body / Kinesthetic
• Auditory / Verbal
• Mathematical / Logical
• Interpersonal
• Intrapersonal

Very few teaching tools can claim the inclusive approach to learning. Does this mean that every teacher must be a dancer as well? Obviously not - but why not? The research sited on this blog in the past confirms over and over that cardiovascular activities increases learning without decreasing test scores if time is taken away from 'regular' classes.

A survey taken in 2000 indicated that only 14% of schools offered any form of dance (excluding PE activities).  Now 36 states offer K-12 teaching credentials in dance. The growth is spurted mainly through PE programs and is increasingly taught as an art form or exercise form. Purists maintain that the art of dance uses movement to create meaning about the human experience and is far more that just art or exercise. Irrespective, dance and other forms of art programs provides a variety of academic and social benefits to students. It seems a powerful way to to promote critical thinking and creativity amongst other skills.

It's time to put on those tapping shoes!

Hot Topics for November!

Now that everyone has weighted in on bullying - from People Magazine to the White House -  I am still confused by the definition of bullying. Is it physical contact, verbal abuse, false third-party stories or all of the above? The physical connotation I get. High school freshman year flash-backs confirm that on. Belittling and 'talk-down' is clear as well. But when someone writes something nasty about another on FaceBook and the ego suffers a bit, is it bullying? It certainly is when the ego is crashed to the point of suicide as recently happened. But where does one draw the line? There will always be someone louder, bigger, and meaner around - irrespective of age and circumstance. Its called 'life' and the nature of humankind. Should we then try to legalize morality to protect perceptions if actions cannot be defined?

Then there was the midterm elections and a dramatic shift in the political balance that could have a huge influence on education in the future. The National Education Association spent $40 million dollars to campaign for candidates from the Democratic Party. But the chairmanship for the committee dealing with educational affairs will be replaced by a Republican due to the House majority. Suddenly the Race to the Top program is in jeopardy, the reauthorization of the 'No Child Left Behind' can change again, and decentralization of education is back on the burner. All I know is that a strong opposition is healthy in any democracy, irrespective the ruling party.

Did you hear about predictions that online learning will overtake traditional classrooms in the next decade? The Los Angeles Times reports that there is no substitute for in-person classroom teaching but that type of education will become the minority by 2020.  Hopefully education leaders will not use it as an excuse to properly maintain real-life buildings!

In Scotland, primary schools are piloting philosophy to improve students' critical thinking and listening skills. Students are engaged in discussions on topics such as society, leadership, and which is better: being strong or being clever. Teachers report that "they have seen clear changes in their listening, in the way they express themselves and how they think". Seems like Plato and Aristotle had it right all this time. Who would have thought?
