This research study was specifically concerned with the development, testing, and revision to an instructional theory for studying the mathematical concepts of equivalence and equation solving with multiple representations and multiple tools. Following a design research approach, a collaborative teaching experiment was conducted with a ninth-grade…

This special issue of the Canadian Mathematics Education Study Group/Groupe Canadien d'Étude en Didactique des Mathématiques (CMESG/GCEDM) Proceedings looks at CMESG/GCEDM's collective history, reflects on where the group has been, and who the members have become as an organization. Through a selection of excerpts from past proceedings, the…

Presents the findings of a study on the learning experiences of undergraduates enrolled in a writing-intensive algebra course. The study revealed that writing activities are successful in terms of facilitating student comprehension of mathematical content. The use of words allows student writers to gain ownership of the algebraic content. (DDR)

The concerns of two teachers at a school where computer-integrated instruction was being used in five second-year algebra classes were studied. High levels of personal and management concerns, coupled with low refocusing concerns, were found. Both teachers were judges as mechanical users of computer materials. (MNS)
