Video tutorials for strengthening mathematical reasoning in rural schools

Abstract

This article is based on a research work whose objective was to strengthen the competence of mathematical reasoning from spatial thinking and geometric systems in fifth-grade students in an educational center of a rural sector through didactic sequences supported with video tutorials that helped improve performance for meaningful learning. The approach of the project was qualitative with an action research design. The techniques used were participant observation, diagnostic tests, development of didactic sequences as evidence of the students’ production, field diary and final test. The diagnostic and final tests made it possible to evaluate the level of performance of fifthgrade students in the area of mathematics, specifically in spatial thinking and geometric systems. It was of great interest to learn about Ausubel’s theory to strengthen meaningful learning and the structure proposed by Tobón for the construction of didactic sequences, which helped improve performance in the area. By achieving the objectives achieved, mathematical reasoning is strengthened from spatial thinking for meaningful learning, with the help of educational videos where it is shown how to give a relevant management to the mediating material (geo plane, tangram and soma cube), to better understand the mathematical processes according to the Basic Learning Rights).
