We reflect on the evolution of an instrument designed to gather data about student actions with dynamic textbooks in university mathematics in a large-scale project. We also discuss the evolution of our understanding of the mediating role of this instrument in gathering data remotely that allow us to access student use and reconstruct their…

Discusses student-teachers' awareness of research and its potential role in their work as teachers, both as methodology for themselves as practicing researchers-in-action and as material developed by others. Some of the influences that led to the rise of the "teachers as researchers" program are included. (KR)

Discussed are research methods as applied to research in the mathematics classroom. Included in the discussion are objectivity, development, evaluation, observation, reflection, research design and methods, and data reduction. (CW)
