This article examines three important facets of the incorporation of new technologies into educational practice, focusing on emergent usages of the mathematical tools of computer algebra and dynamic geometry. First, it illustrates the interpretative flexibility of these tools, highlighting important differences in ways of conceptualizing and…

The idea of "interpretative flexibility" underpins new approaches to studying technological artefacts and curricular resources in use. This paper opens by reviewing, in this light, the evolving design of dynamic geometry, its pioneering use within classroom projects, and early sketches of its mainstream use in ordinary classrooms. After…

This paper argues that better understanding of the educational integration of new technologies calls for broader account to be taken of the complex ongoing practices of school mathematics education. To frame its concerns, the paper opens by drawing on key studies of the general place of technology in classroom practice and teacher thinking. The…

Drawing on evidence from lesson observations, teacher interviews and project reports, this paper examines the pedagogical perspectives and strategies of teachers working to incorporate use of Internet resources and associated ICT tools into humanities, social studies and science lessons in English secondary schools. The eight teachers were…
