The "Effecting Principled Improvement in STEM Education" ["epiSTEMe"] project undertook pedagogical research aimed at improving pupil engagement and learning in early secondary school physical science and mathematics. Using principles identified as effective in the research literature and drawing on a range of existing…

Lesson Study is rapidly becoming one of the most adopted models of teacher professional development worldwide. In this paper, we examine the teachers' discussions that are an integral part of the Lesson Study research cycle. In particular, we investigate the "dialogic mechanisms" that enable teachers' pedagogical intentions to be…

In response to continuing concerns about student attainment and participation in science and mathematics, the "epiSTEMe" project took a novel approach to pedagogy in these two disciplines. Using principles identified as effective in the research literature (and combining these in a fashion not previously attempted), the project developed…

Drawing on the work of researchers in several disciplines, this article describes and discusses methods which can be used for analysing joint activity during computer-based, side-by-side, collaborative activity in educational settings. It is argued that the choice of methods in any particular study should take into account the range of…
