Finally, I want to emphasize that I am not an enemy of curriculum reform. I have been
teaching for more than thirty years, and have reformed my own curriculum many times. I
have written quite often about some of my own reforms, in case there is anything in them
that might be of value to others. I value very highly the anecdotes and stories that fine
human beings and gifted and sensitive teachers tell, about what worked for them in their
classrooms. True reforms can be proposed and debated without the necessity of doing
double-blind studies.
