Collectivism and behaviorism are the main educational paradigms that describe the two most popular types of MOOCs, called cMOOCs and xMOOCs. Some aspects of the pedagogical approach in this sort of courses are the subject of study and debate at present, such as the quality of these new learning mechanisms. In this paper, some reflections are shown about the problem of pedagogy that must be solved, such as pedagogical approaches and in the same way, the approaches of different authors to contribute to the adequate quality of MOOCs.
