In this presentation we present a study in which we explored the use of a research assignment on instructional design of MOOCs by MOOC students. The use of a research assignment was expected to be of interest for both students and the designer. The assignment is based on a framework to analyse MOOC designs with the objective to identify best practices. It builds on four principles: constructive alignment, task complexity, interaction and formative feedback. The exploration indicates that students positively appreciate this kind of assignments. Moreover, the crowdsourcing alike approach showed to be a valuable way for MOOC designers to get awarded with data gathered by their participants. The participants, be it a small sample, were able to apply the framework to analyse MOOCs and identify best practices. We will discuss the framework and the results of its application. Finally, we will conclude with the experiences of the users.
