One of the best articles I've read on education in a while; it's quite long, but worth it.
This is one of my favourite sections.
"Any wildlife biologist knows that an animal in a zoo will not develop
normally if the environment is incompatible with the evolved social
needs of its species. But we no longer know this about ourselves. We
have radically altered our own evolved species behavior by segregating
children artificially in same-age peer groups instead of mixed-age
communities, by compelling them to be indoors and sedentary for most of
the day, by asking them to learn from text-based artificial materials
instead of contextualized real-world activities, by dictating arbitrary
timetables for learning rather than following the unfolding of a child’s
developmental readiness. Common sense should tell us that all of this
will have complex and unpredictable results. In fact, it does. While
some children seem able to function in this completely artificial
environment, really significant numbers of them cannot. Around the
world, every day, millions and millions and millions of normal bright
healthy children are labelled as failures in ways that damage them for
life. And increasingly, those who cannot adapt to the artificial
environment of school are diagnosed as brain-disordered and drugged."
Although there are quite a few bit in it that I like.
Here is Carol Black's blog. I haven't looked through it yet, but the article was taken from here.
