Matrices and Images: A Didactic Proposal for High School Using the GNU Octave Programming Language
Matrices; Octave; Digital Images.
This research proposes a didactic approach to teaching matrices in high school, integrating mathematical concepts with the GNU Octave programming language. The proposal arises from the need to make the teaching of matrix algebra more meaningful and contextualized for students by using digital images as a pedagogical resource. Through the manipulation of images via matrix operations, students are led to understand abstract matrix concepts such as dimensions, operations, and transformations in a concrete and visual manner. The adopted methodology involves practical and experimental activities in a computational environment, promoting interdisciplinarity between Mathematics and Technology and encouraging student autonomy in problem-solving. The observed results indicate that the proposal fosters active learning, stimulates interest in mathematics, and contributes to the development of computational thinking.
