This document discusses Marta Cáceres-Piñuel's PhD research on MOOCs and their role in creating open communities of knowledge. Her hypothesis is that MOOCs enable more than just massive online courses - they create new online spaces for knowledge sharing. She analyzes data from surveys and learning analytics from two MOOC platforms to study how students interact and form knowledge networks. A case study examines a MOOC on transversal competencies for entrepreneurship with over 260,000 total students and 5,602 students in the course. The document provides background on the theoretical frameworks of networking analysis and connectivism that inform the research.
