Exercises to enhance the learning of the chemical properties of dihydrogen for 10th-grade

Abstract

From Basic Secondary Education, a better foundation in student knowledge is required due to the transformations in Pre-University Education. This research aims to develop a set of exercises to enhance the learning of the chemical properties of dihydrogen for 10th-grade students at IPU Roberto Ramírez Delgado. The theoretical references that support the teaching-learning process of the Chemistry subject are addressed, the current state of Chemistry learning among students is diagnosed, a set of exercises is proposed to promote the learning of the chemical properties of dihydrogen, and an evaluation of the results achieved from implementing the set of exercises in pedagogical practice is conducted. The research employs theoretical, empirical, and statistical methods. Among the theoretical methods: analysis-synthesis and induction-deduction. Among the empirical methods: observation, surveys, pedagogical tests, and document analysis. From mathematical statistics: techniques of descriptive statistics and percentage calculation. The set is applied in pedagogical practice, achieving significant changes that enhance students' learning in the Chemistry subject.
