This document summarizes the results of a Group Concept Mapping (GCM) study conducted to identify guidelines for designing MOOCs. Experts generated 113 ideas that were sorted into 79 statements and rated on importance and difficulty. Multidimensional scaling and cluster analysis identified 7 clusters of guidelines: Assessment, Organizational Issues, Hybrid Construction/Technological Affordances, Instructional Strategies, Self-Directed Learning, Learning Design Theoretical Background, and Learning Networks. The clusters were rated on importance and difficulty, with Organizational Issues and Learning Design rated most important and easiest respectively. Pattern analysis found little difference in ratings between cognitive styles.
