This paper proposes a model for usability learning in a collaborative manner. The model has been applied in a controlled experiment with advanced students from the computer science programs in four public universities in Latin America, that belong to community called LACXSER (Latin American Co-laboratory on Software Engineering Research eXperimental). The application of the model facilitated the collaborative work between geographically dispersed educational institutions and served as a medium for teaching and learning topics related to assessing the usability of interfaces, through a scheme of distributed collaborative work.
