CG.LAB: plataforma interativa para o ensino de álgebra linear aplicada a computação gráfica

Abstract

Linear Algebra is a fundamental component in various fields of computing, especially in Com- puter Graphics, where concepts such as vectors, matrices, and geometric transformations are

widely used. However, teaching this subject presents challenges due to its abstract nature and the difficulty students face in visualizing practical applications. This work presents the development of CG.lab, an interactive web platform that functions as a Virtual Learning Laboratory (VLL),

focused on teaching Linear Algebra applied to Computer Graphics. The platform offers interac- tive exercises with 2D and 3D visualizations, allowing direct manipulation of points, vectors,

and matrices. It also incorporates initial gamification elements, such as daily missions, usage streaks, and immediate feedback, aiming to enhance student engagement. The methodology included requirement gathering through brainstorming, followed by system development and the application of a case study with students from a Computer Graphics course. This is an applied research with a mixed-methods and exploratory approach. The evaluation was conducted through a questionnaire, whose results indicated positive perceptions regarding usability, interactivity, and the tool’s contribution to content comprehension, in addition to collecting valuable suggestions for improvement. As future work, the implementation of these suggestions is proposed, along with the expansion of gamification elements and new evaluations with students from both Linear Algebra and Computer Graphics courses.
