Evaluation of the Impact of an Online Educational Platform on the Development of Mathematical Competencies in Elementary School Students

The research aims to assess the impact of the online educational platform Khan Academy (KA) on the development of mathematical competencies in regular basic education students. A longitudinal methodology was employed to evaluate this impact on the students. An experimental group of 25 students was formed, who were selected through convenience sampling, considering specific inclusion and exclusion criteria. Pretest and posttest assessments were applied to measure various mathematical competencies. The study reveals that, before the use of Khan Academy, students had varying levels of mathematical skills. Following its implementation, a significant improvement was observed in competencies related to solving quantity, shape, movement, and location problems, although there was less progress in solving regularity, equivalence, and change problems. These findings suggest that Khan Academy may be effective in enhancing academic performance in mathematics, but it is emphasized the importance of being a complement to conventional education to address specific student needs. The competency related to the ability to communicate mathematical knowledge was strengthened, highlighting the versatility of the platform. In conclusion, the implementation of Khan Academy emerges as a valuable educational tool, positively impacting the achievement of key competencies and specific mathematical skills. Khan Academy proves to be an effective pedagogical strategy when carefully integrated under teacher guidance.
