E-Learning in the Teaching of Mathematics: An Educational Experience in Adult High School Moreno Guerrero, Antonio José Aznar Díaz, Inmaculada Cáceres Reche, María Del Pilar Alonso García, Santiago This study has been financed by the “Study and analysis of technological resources and innovation in teacher training in the field of Higher Education and its applicability to the development of the Santander Region (Colombia)”, in the Framework Cooperation Agreement for the strengthening of research and education, signed between the Corporación Escuela Tecnológica del Oriente, the Secretariat of Education of Santander and the AreA HUM/672 Research Group of the University of Granada. Code: ISPRS-2017-7202. Period: 2017–2021. Currently, the e-learning method, due to the period of confinement that is occurring due to COVID-19, has increased its use and application in the teaching and learning processes. The main objective of this research is to identify the effectiveness of the e-learning method in the teaching of mathematics with adults who are in high school, in contrast to the traditional expository method. The study developed is quantitative, descriptive and correlational. The research design is quasi-experimental, with a control group and an experimental group. The results show that the use of the e-learning method has a positive influence on motivation, autonomy, participation, mathematical concepts, results and grades. It can be concluded that the e-learning method leads to improvement in adult students who are studying the mathematical subject in the educational stage of high school, provided that it is compared with the expository method. Therefore, this method is considered effective for its implementation in adults. 2025-03-26T13:04:07Z 2025-03-26T13:04:07Z 2020-05-22 journal article Moreno Guerrero, Antonio José et al.
