It has become a central issue not only in sociocultural studies but also in the experimental research on CSCL. Investigating these various forms of orchestration raises several methodological challenges for CSCL research which cannot be elaborated fully here. Among the most important methodological challenges are the following: 1. How to ensure knowledge accumulation in CSCL orchestration research when concepts and methods become increasingly heterogeneous? g. Arnseth & Ludvigsen, 2006). Given the call for including rather more heterogeneous concepts from different social planes and potentially from different scientific disciplines, the threat of fostering the problem of low knowledge accumulation is high.

Tools can be regarded as a way of constructing and expressing what is learnt from the inquiry process using this representation (tools as means). Systems or phenomena can be presented using these external 2 Developments in Inquiry Learning 27 representations. , 2002; Grosslight, Unger, Jay, & Smith, 1991; Harrison & Treagust, 2000; Zacharia, 2005). In this case, understanding is linked to the tools and the representations these tools employ. The final products of these tools can be considered as representational constructs that reflect learners’ understanding and skills (Papaevripidou, Constantinou, & Zacharia, 2007).
