The purpose of this work is to make a comparative analysis between different approaches to MOOC that are developed in the Polytechnic of Leiria. We compared 4 course formats created by our institution based on classifications and taxonomies that have been proposed by several authors as a way to understand the diversity of the MOOC format. The main goal of this comparison is, on one hand, to classify our typology of courses, both in terms of learning design and institutional investment, and notice if parameters that distinguish these approaches affect the student's path and consequently the course completion rate. We used the table compiled by Major & Blackmon (2016) adding new aspects such as technical and human resources, teacher´s role and content types. Results have shown us that there is no significant variation relative to the completion rate, although there is a variation regarding the institutional effort.
