Structuring CSCL through collaborative techniques and scripts

This paper is rooted in the research field of Computer Supported Collaborative Learning (CSCL), where the debate is lively around whether and to what extent structuring the interactions among students enhances the effectiveness of the collaborative process. The paper discusses two different design approaches to structuring collaboration: the former approach, adopted in the context of an Italian online course, is based on the use of a set of collaborative techniques, while in the latter, proposed in a German context, collaboration scripts are used to guide students step-by-step. The study describes and then compares the strengths and weaknesses of the two approaches. What can be learned from the two experiences? Is there any possibility - and with what advantages - of integrating the two approaches, so as to gain from both
