Teaching strategy based on Genially in natural sciences in high school for the improvement of academic performance

Abstract

Genially is closely linked to active methods by allowing the creation of interactive teaching materials where the student is no longer a passive recipient. The objective was to develop a Genially-based teaching strategy for Natural Sciences in high school to improve academic performance in seventh grade. The approach was quasi-experimental, applied, cross-sectional, and correlational. The diagnostic instruments and the proposed solution were supported by the use of theoretical methods. The diagnosis was based on empirical methods and the use of mathematical and statistical tests (Cronbach's alpha, R-squared, Kolmogorov-Smirnov and Shapiro-Wilk, Student's t-test, Spearman's R-squared, Iadov indices, and NPS) processed with SPSS software. The Genially-based teaching strategy was implemented with six activities, for which the format and methodological suggestions for their implementation are established. The average grade point average (6.38-8.38 in the experimental group) showed a statistically significant increase and the variables studied were correlated with academic performance. The NPS and Iadov indices show values above 50, demonstrating its applicability, its contribution to solving the problem, and the willingness to make it widely available.
