“Let me suggest one answer [to the problem of going into depth and avoiding excessive coverage] that grew from what we have done. It is the use of the organizing conjecture. They serve two functions, one of them obvious: putting perspective back into the particulars. The second is less obvious and less surprising. The questions often seemed to serve as criteria for determining where [students] were getting and how well they were understanding.”
