Editorial: the role and influence of key stakeholders in the learning technology community

In this issue of ALT-J we have six articles that address three broad topics of video, costbenefit analysis and the emergent learning technology community. The first two articles present case studies on the use of video in teaching and learning. Shephard et al. describe their experiences of re-purposing a back 'care video' for video streaming, and use these experiences to highlight key challenges that others may face when attempting to re-purpose a video. Blake and Scanlon use their experiences of analysing video recordings of students, who were using computers to support their collaboration in solving statistical problems, to argue that such video analysis provides useful rich data with which to interpret and understand students' experiences.
