The aim of this paper is to present a model for developing computer-based laboratory activities in the undergraduate course Introduction to Linear Algebra at the Pontificia Universidad Católica de Chile, and to discuss some of the findings observed during the implementation. The purpose of the model is to introduce students, both from the mathematics degree program and prospective secondary mathematics teachers to basic programming concepts through problem-solving, using questionnaires presented in an HTML format. To facilitate learning, these questionnaires will be solved using SageMath as a computational algebraic system of support and Canvas LMS as a learning management system. The presented model aims to leverage the advantages of digital tools to enhance the teaching and learning of linear algebra. The integration of SageMath and Canvas LMS enables an interactive and asynchronous learning experience, where students can explore mathematical concepts at their own pace and receive immediate feedback. However, it is also emphasized in the article that it is important to consider individual differences among students and adapt the model accordingly to meet their needs and abilities.
