An aid to ‘uncovering’ mathematics: a select bibliography
BILL HIGGINSON
Some mathematics teachers have traditionally thought of their work in terms of “covering topics”. Given a class and a certain number of periods per week, one took a textbook and proceeded to cover the .material. It was all quite straightforward, but there were two problems. The first was that for all too many students, one might just as well have been covering “Geometric Constructions”, or whatever, with a blanket. The other problem was that over the years the danger of slipping into a pedagogical rut was very great.
