Nowadays, University needs to assess the university teaching activity in a framework where new ways of learning are being carried out. ANECA offers a model and set of procedures that guide the activities of the university, without prejudice to the autonomy of it. Therefore, as the new settings are not being analyzed in depth, this paper makes a research proposal for assessment of university teaching in virtual learning environments, that includes four componentes: planning and content of the course, teacher's activity, interaction with peers and environment. These factors have been identified through the development of a causal model and its estimation using a structural equation analysis. [ABSTRACT FROM AUTHOR]
