These papers from the fifth annual meeting of the Canadian Mathematics Education Study Group are organized similarly to the meeting, presenting materials from the lectures, working groups, special groups, and panel groups, as well as ad hoc groups. Iverson delivered one lecture on computer programming, stressing the place of APL, while Kilpatrick lectured on theoretical and methodological reasons why research in mathematics education has made little impact on classrooms so far. Working group reports concerned research and the classroom, computer education for teachers, issues in the teaching of calculus, and revitalizing mathematics in teacher education courses. Special groups reported on the place of geometry in the elementary school and an example of mathematics, the Rubik cube. Panels considered mathematics and language, and the relationship of history and the teaching of mathematics. In the appendix are reports from individual members of the working groups and panel groups, concerning a variety of mathematics education topics. (MNS)
