Fernando Gouvêa in American Scientist:
Tools of American Mathematics Teaching, 1800–2000, by Peggy Aldrich Kidwell, Amy Ackerberg-Hastings and David Lindsay Roberts, is a historical survey of several of the objects that have formed, at some point during the past 200 years, the “material culture” of the American mathematics classroom. Each chapter is an essay focusing on one particular kind of object. Some treat things that are in general use, such as textbooks, blackboards and overhead projectors. Others study objects that are found almost exclusively in the mathematics classroom: protractors, blocks, beads, geometric models, slide rules, graph paper and the like. The four final essays focus on electronic technology.
In every case, we get both a close analysis of the objects themselves and a discussion of the available texts describing (and often promoting) their use.
