Análisis general de prácticas y recursos digitales en la enseñanza de la Estequiometría y diseño de una propuesta didáctica mediada por TIC para estudiantes de segundo año de bachillerato de la Unidad Educativa Miguel Malo González

Abstract

Abstract: Stoichiometry poses a challenge for motivation and active work in the classroom and for academic performance. The purpose of this study was to analyze teaching practices and the use of digital resources in the teaching of stoichiometry in order to design an ICT-mediated teaching proposal for second-year high school students at the Miguel Malo González Educational Unit. The methodology was mixed, descriptive and explanatory in scope, bibliographic, field-based, and inductive-deductive in nature. A sample of 13 students was used, with a pretest, posttest, and satisfaction survey. The results of the pretest indicated an average of 68,5% correct answers. Therefore, a teaching proposal was designed that incorporated active methodologies, TPACK, ERCA, and DUA, which, after a three-week intervention, showed an overall improvement in the posttest of 81,5%, as well as high scores in student satisfaction, motivation, and acceptance. It was concluded that active methodologies and digital tools serve to stimulate motivation and lead to meaningful learning in stoichiometry.
