The article describes mathematicians' pedagogical perspectives on proof in the teaching of first year university students at a mathematics department in Sweden. A conceptual frame that was used in the data analysis combines theories about proof from earlier mathematics education research with a social practice approach of Lave and Wenger. A…

Describes a method whereby data are first analyzed episode-by-episode in comparison to each other. Conjectures thus generated are then meta-analyzed to create chronologies structured by general assertions grounded in students' mathematical activity. Clarifies the relation between psychological and social processes. (TO)

Describes the role of an instructional sequence and two accompanying computer-based tools in supporting students' developing understandings of statistical data analysis. Documents the emergence of the sociomathematical norm of what counts as a mathematical argument in the context of data analysis. (Author/MM)

In this paper, characteristics of mathematics classrooms in the East Asian countries of Hong Kong and Japan are discussed based on an analysis of the data of the TIMSS 1999 Video Study. The data shows that although students in these East Asian countries did not talk a lot in the classroom, they were exposed to more instructional content. The…
