This study intends to put available a plan of direction to a job line connecting of three areas: Graphic Design Studies, Human-Computer Interaction (HCI) and Pedagogy. The lack of researches that involves these three areas reveals the lack of suitably defined criteria to build distance learning support. This investigation analyses the designer performance as an area that can make easy to understand the information and the communication in the learning environment mediated through internet. Information and communication problems were considered essential factors in the educational environment configuration for the studies done in this present dissertation. This investigation brought up the necessity to consider the use of Design tools to configurate distance learning environments, specially in this moment where information technology is sensibly transforming individual`s enviroments and the social relationship. This research presents a Guide to Interface Design s analysis, the goal is to test usability aspects in distance learning environments, under the focus of Design, Human-Computer Interaction and Pedagogy. Such procedures intend to develop the interfaces focused on the user and enhance educational environments standards, making the distance learning more productive and interactive. The Guide validation, object of this present dissertation, was done with the use of the environment Oficina Projeto Didático, offered by CCEAD (Coordenação Central de Educação a Distância da PUC-Rio, which uses LMS (Learning Management System) denominated Aulanet.
