Explorando Circuitos Eléctricos con el apoyo de Material concreto: Evaluación de una propuesta didáctica

Abstract

This research analyzed the academic impact of implementing teaching guides with concrete materials on electrical circuits in the second year of high school at the Guillermo Mensi Educational Unit during the 2024-2025 period. The study adopted a quantitative approach and worked with two groups: experimental and control. The independent and dependent variables were the teaching guides with concrete materials and academic performance, respectively. Students in the experimental group worked with the proposed approach, while the control group followed the traditional approach. Data collection involved a pretest and posttest on knowledge of electrical circuits, which were validated by expert judgment. The data were subsequently processed and analyzed using statistical tests of normality, homogeneity of variance, and comparison of means, which allowed for the analysis of results between the experimental and control groups. The Student t-test, with a p-value less than 0.05 (p < 0.05), indicates significant improvements in the academic performance of the experimental group. The study shows that the implementation of teaching guides with concrete materials facilitates the understanding and application of topics such as Ohm's law and electrical circuits, indicating that the approach used fosters effective learning.
