The e-learning systems allow users to improve the traditional education systems granting flexibility, permanence, and synchrony. Many e-learning systems are based on the use of web applications and games. A trivia quiz is a game metaphor which allows to enhance the teaching-learning process in an entertaining, constant and motivating way for students. This work presents Edutrivias, a web system created to support the teaching-learning process through trivia quizzes. Edutrivias uses the trivia quiz as an educational resource that allows positive reinforcement, monitoring, control and effective feedback of student learning. The description of the web system and an exploratory case study are presented. Preliminary results show that Edutrivias generates a positive impact on students, encouraging self-learning and supporting knowledge retention.
