Blind procedures vs. discovery and mathematical experiences. As we mention in our HS Source Book, we feel that all too often the standard approach to teaching math is based on “blind procedures”; students simply follow procedures without any understanding of what they are doing. In contrast, we have tried to put together our high school workbooks so that, whenever possible, the students are led on a path of discovery.

We also feel that mainstream mathematics emphasizes procedural skills too much. Often, 90% of classroom time (or more) is spent having the students slog through countless “problems”, all in the name of checking off topics on the LIST, and ensuring ourselves that our students have good “skills” (at solving meaningless problems). In contrast, we believe it is important to have a healthy balance between procedural skills and real “mathematical experiences”.
