This study investigates the potential of multimedia learning materials to improve the possibilities of knowledge construction processes about computer graphics technology. The primary hypothesis was that information in multimedia format, could contribute to overcome epistemological obstacles students encounter, more effectively than printed literature, and improve the quality of their learning. We designed multimedia learning materials, using appropriate pedagogy and instructional strategies. We gave them to the students and used them for teaching. The results suggest that the hypothesis could be corroborated, thus indicators of knowledge level and quality of the students, showed a significant upswing.
