Problem Based Learning (PBL) is a new teaching-learning method originated from the changes that have occurred in the world economical basis and in the information and communication technologies. The purpose of this paper is to describe the architecture of PBL Virtual Environment and the initial simulation results of tutorial sessions carried out by staff and students participating on the Computer Engineering course at the State University of Feira de Santana (UEFS). The modeling of the PBL method and its mapping in XML schema based on the PBL tutorial sessions have allowed to implement an application that suports presential and distance PBL tutorial sessions. The main contribution of this paper consists on findings obtained from the application of PBL Virtual Environment to a group of students related to the course of Computer Engineering (UEFS). These findings would be used to improve the development of collaborative learning environments. KEYWORDS Problem-Based Learning, PBL Virtual...
