  In this work-in-progress paper, we introduce the PerspectivesX tool which
aims to scaffold collaborative learning activities within MOOCs. The
PerspectivesX tool has been designed to promote learner knowledge construction
and curation for a range of multi-perspective elaboration techniques (e.g.,
SWOT analysis and Six Thinking Hats). The PerspectivesX tool is designed to
store learner submissions in a searchable knowledge base which is able to be
persisted across course re-runs and promotes the use of natural language
processing techniques to allow course moderators to provide scalable feedback.
In this paper we outline the design principles that structured collaborative
learning tools need to adhere to, design a prototype tool (PerspectivesX) and
evaluate whether MOOC platform extension frameworks are able to support the
implementation of the tool.
