In recent years, researchers have extended this perspective to a variety of educational and instructional contexts, for example, problem-based learning in medical education (Glenn et al, 1999), laboratory work in physics education (Ford, 1999;Lindwall and Lymer, 2008), the role of technology in architectural education (Lymer et al, 2009;Ivarsson, 2010), online learning environments (Garcia and Jacobs, 1999;Çakir et al, 2009), as well as postgraduate training in mathematics (Greiffenhagen and Sharrock, forthcoming There are important respects in which the 'analytic mentality' (Schenkein, 1978) of ethnomethodolology and conversation analysis differs from the aims and methods of much research in CSCL, in particular, (1) the emphasis on analytic description rather than evaluation, (2) the focus on manifest rather than hidden aspects of interaction, (3) the dissolution rather than integration of supposedly different levels of social organisation.…”
