Research on Computer-Supported Collaborative Learning (CSCL) is a multidisciplinary field located at the intersection of cognitive psychology, computer science, and education. Yet, the different epistemological and theoretical backgrounds of these disciplines often make fruitful exchange between them difficult. CSCL urgently needs to develop and use boundary concepts that can bring these fields closer together to improve cumulative research and development of computer-supported learning environments. Scripting Computer-Supported Collaborative Learning focuses on one term with the potential to become a real boundary concept in CSCL—"scripting".
