In the late seventies, Guy Brousseau set himself the goal of verifying experimentally a theory he had been building up for a number of years. The theory, consistent with what was later named (nonradical) constructivism, was that children, in suitable carefully arranged circumstances, can build their own knowledge of mathematics. The experiment,…

Addresses the challenges, risks, and rewards of teaching about linear functions in a technology-rich environment from a constructivist perspective. Describes an algebra class designed for junior high school students that focuses of the representations and real-world applications of linear functions. (MDH)

Describes the structure and content of SummerMath for Teachers, an experimental mathematics course designed to help inservice teachers become mathematical thinkers. The course was organized around mathematical explorations and focused on mathematical processes. Includes excerpts from teachers' journals. (Contains 17 references.) (MKR)
