El uso de la tecnología para el aprendizaje de funciones trigonométricas en el nivel preuniversitario

Abstract

Abstract:The objective of this degree work was to analyze the use of technology as a tool of improvement for learning trigonometric functions at the pre-university level. HE chose Khan Academy as the educational technology, for its accessibility, ease of use, perception of trigonometric concepts and their compatibility with Based Learning in Trouble (ABP). The quantitative methodology included a sample of 50 students divided into control and experimental groups. A pretest was applied to both groups to evaluate initial knowledge and a Posttest to measure progress using technology as a resource of learning. A didactic sequence was designed that integrated PBL with the ERCA cycle (Explore, Reflect, Conceptualize, Apply) supported by Khan Academy. The results showed a positive perception towards the tool and improvements in understanding and solving trigonometric problems. The Mann-Whitney U statistical test revealed a significant difference (p-value = 0.00 < 0.05) between students who used Khan Academy and those that are not, confirming its effectiveness and suggesting its integration into the curriculum pre-university to improve academic performance.
