“…Some scholars therefore reject the idea of learning as an activity system (Holzkamp, 1983), whereas others insist that learning can be planned and analyzed as activity system (e.g., Davidov, 1988;Lompscher, 1999). A snapshot of activities described in the CHAT educational literature include redesigning instruction (Jonassen & Rohrer-Murphy, 1999; S. Lee & Roth, 2003a), planning for teacher learning (Ball, 2000;Edwards & Protheroe, 2004;Grossman, Smagorinsky, & Valencia, 1999;Kärkkäinen, 1999), providing for learning or physical disabilities (Bakhurst & Padden, 2001;Daniels & Cole, 2002;Kosonen & Hakkarainen, 2006), and managing schools (Gronn, 2000;Spillane, Halverson, & Diamond, 2004); all these concrete activities, as true of activities in general, are characterized by the collective nature of their motives (Leont'ev, 1981). In the realization of collective motives, an activity system contributes to the survival of society and therefore the survival of each individual, in and through whose actions society is realized and exists (Holzkamp, 1991).…”
