摘要:Traditional university instructional formats and methods are experimenting an increasing lack of effectiveness, mainly because student's lack of motivation. The NUCLEO e-learning system tries to approach the learning scenario to the engaging and immersive formats of the videogames. It provides a futurist scenario in which students (represented by avatars) have to collaborate to solve a learning “mission”. The proposal is based in two socio-constructivist approaches, problem based learning and computer supported collaborative learning and it makes use of adaptation techniques to optimize group effectiveness and to individualize the educational strategy by considering students' learning styles.
