The Second Information Technology in Education Study — Module 2 (SITES‐M2) in Germany investigated 12 cases of innovative pedagogical practice using technology (IPPUT) in primary, lower and upper secondary schools. One theme that emerged from the analysis of these cases was students' cooperation. It seems that the co‐occurrence of ICT‐use and students' cooperation and collaboration is not accidental. The focus of this paper is an analysis and classification of the students' cooperation identified in the IPPUTs.

In the development of didactics of mathematics as a professional field in Germany, subject-related approaches play an important role. Their goal was to develop approaches to represent mathematical concepts and knowledge in a way that corresponded to the cognitive abilities of the students without disturbing the mathematical substance. In the 1980s, views upon the nature of learning as well as objects and methods of research in mathematics education changed and the perspective was widened and opened towards new directions. This shift of view issued new challenges to subject-related considerations that are enhanced by the recent discussions about professional mathematical knowledge for teaching.
