<strong>Teach<strong>in</strong>g</strong> with <strong>the</strong> <strong>Bra<strong>in</strong></strong> <strong>in</strong> M<strong>in</strong>d<br />
direct phonics <strong>in</strong>struction more bra<strong>in</strong> compatible?<br />
Research suggests <strong>the</strong>re is value <strong>in</strong> each; a comb<strong>in</strong>ation<br />
is best.<br />
The Sudbury Valley School <strong>in</strong> Fram<strong>in</strong>gham,<br />
Massachusetts, is an example of a school that<br />
understands how read<strong>in</strong>g read<strong>in</strong>ess and <strong>the</strong> differences<br />
<strong>in</strong> learners’ bra<strong>in</strong>s can coexist. Their K-12<br />
program does not force read<strong>in</strong>g on any student.<br />
They believe that youngsters are already exposed<br />
to thousands of vocabulary words <strong>in</strong> <strong>the</strong> world.<br />
Instead of teach<strong>in</strong>g <strong>the</strong>m read<strong>in</strong>g, <strong>the</strong> school simply<br />
lets students choose to do it when <strong>the</strong>y are<br />
ready. As a result, some children read at age 5, o<strong>the</strong>rs<br />
at 6, some as late as 10. But accord<strong>in</strong>g to <strong>the</strong><br />
school’s founder, Daniel Greenberg, <strong>the</strong> school has<br />
100 percent truly functional, literate graduates.<br />
There are no read<strong>in</strong>g disorders or dyslexia, and<br />
everyone likes to read. It’s an approach that says,<br />
“Wait until <strong>the</strong> bra<strong>in</strong>’s ready to read, <strong>the</strong>n you can’t<br />
stop it!” (Greenberg 1991).<br />
Sweet Dreams<br />
Teachers often compla<strong>in</strong> about kids fall<strong>in</strong>g asleep <strong>in</strong><br />
school. Is it <strong>the</strong> parent’s fault or <strong>the</strong> school’s? Studies<br />
ask<strong>in</strong>g why kids seem to fall asleep so often <strong>in</strong><br />
middle and high school classes have now turned to<br />
biology. Researchers had already looked at two possible<br />
culprits that, <strong>in</strong> <strong>the</strong> end, didn’t seem to matter<br />
much: part-time work and go<strong>in</strong>g to bed late. The<br />
answer wasn’t social pressure, ei<strong>the</strong>r. It was puberty.<br />
Sleep is regulated by many chemicals, <strong>in</strong>clud<strong>in</strong>g<br />
am<strong>in</strong>es, glutocorticoids, and oleamide, a<br />
drows<strong>in</strong>ess-<strong>in</strong>duc<strong>in</strong>g chemical substance, says Dale<br />
Boger, a molecular biologist at Scripps Research<br />
Institute <strong>in</strong> La Jolla, California. A delayed accumulation<br />
of oleamide means a teen’s natural sleep<br />
clock generates a natural bedtime closer to midnight<br />
with a wak<strong>in</strong>g time closer to 8 a.m. This<br />
24<br />
change is believed to be stimulated by <strong>the</strong> hormonal<br />
changes of puberty. Sleep expert Mary<br />
Carskadon, formerly of Brown University, confirms<br />
that most teenagers are affected by this critical<br />
biological change <strong>in</strong> <strong>the</strong>ir <strong>in</strong>ternal sleep clocks (<strong>in</strong><br />
Viadero 1995). “We have kids so sleep-deprived,<br />
it’s almost as if <strong>the</strong>y’re drugged. Educators like<br />
myself are teach<strong>in</strong>g walk<strong>in</strong>g zombies,” says Cornell<br />
University sleep disorder expert James Maas (<strong>in</strong><br />
L. Richardson 1996, p. E-1). Sleep experts discovered<br />
that teens simply couldn’t fall asleep early, as<br />
<strong>the</strong>ir frustrated parents suggested. Carskadon calls<br />
it a “delayed phase preference,” and <strong>the</strong> body’s<br />
chang<strong>in</strong>g chemistry is <strong>the</strong> culprit. While many<br />
researchers are unsure of <strong>the</strong> direct cause, <strong>the</strong><br />
results are easy to see. They should be able to get<br />
to sleep earlier, but <strong>the</strong>y can’t. It’s like <strong>the</strong> biological<br />
clock <strong>in</strong>jected amphetam<strong>in</strong>es <strong>in</strong>to <strong>the</strong> bra<strong>in</strong>.<br />
Milton Erman, professor at <strong>the</strong> University of California<br />
<strong>in</strong> San Diego, says, “High school kids are<br />
grossly sleep deprived. . . . [I]t makes very little<br />
scientific sense to make <strong>the</strong>se kids function at<br />
<strong>the</strong>se very early hours” (<strong>in</strong> L. Richardson 1996,<br />
p. E-1). Richard Allen of <strong>the</strong> Sleep Disorder Center<br />
at Johns Hopk<strong>in</strong>s University studied two groups of<br />
teens. The later risers performed better academically.<br />
One started school at 7:30 a.m., <strong>the</strong> o<strong>the</strong>r at<br />
9:30 a.m.<br />
Researchers have discovered that at night, <strong>the</strong><br />
first few m<strong>in</strong>utes and <strong>the</strong> last few m<strong>in</strong>utes of our<br />
four-part sleep cycle take us <strong>in</strong>to a <strong>the</strong>ta state.<br />
That’s our own “twilight zone,” when we are half<br />
awake and half asleep. <strong>Bra<strong>in</strong></strong> wave cycles here are<br />
about 4–7 per m<strong>in</strong>ute as we drift randomly <strong>in</strong> and<br />
out of sleep. Ord<strong>in</strong>arily, our wak<strong>in</strong>g hours are spent<br />
<strong>in</strong> alpha and beta time, from 8–25 cycles per second.<br />
Dur<strong>in</strong>g <strong>the</strong>ta state, we can be awakened easily<br />
and often rehash <strong>the</strong> day or th<strong>in</strong>k of th<strong>in</strong>gs we have
