This paper investigates the role of instructional supports for argumentation-based computer supported collaborative learning (ABCSCL), a teaching approach that improves the quality of learning processes and outcomes. Relevant literature has been reviewed to identify the instructional supports in ABCSCL environments. A range of instructional supports in ABCSCL is proposed including scaffolding, scripting, and representational tools. Each of these instructional supports are discussed in detail. Furthermore, the extent to which and the way in which such instructional supports can be applied in ABCSCL environments are discussed. Finally, suggestions for future work and implications for the design of ABCSCL environments are provided. Article visualizations
