I've also taught elementary school children. 4th, 5th, 6th, 7th, and 8th grade science.
The kids I taught were at a Montessori school and had been since kindergarten. Montessori kids (that have been in the program a long time) are notorious self-starters and the entire school excelled at the standardized tests and the teachers do not spend much time at all on test preparation.
I realize that I taught with what was probably an exceptional group and that my story isjust one anecdote.
But I still think kids *can* do this stuff and that we have a crisis in education that involves teachers, parents and kids not applying themselves.
