" Of all I saw and learned this past half year, one thing stands out. What goes
on in the class is not what teachers think-- certainly not what I had always
thought. For years now I have worked with a picture in mind of what my
class was like. This reality, which I felt I knew, was partly physical, partly
mental or spiritual. In other words, I thought I knew, in general, what the
students were doing, and also what they were thinking and feeling. I see now
that my picture of reality was almost wholly false. Why didn’t I see this
before? "
