FROM THEORY TO PRACTICE: THE INFLUENCE OF LOW-COST EXPERIMENTS IN TEACHING COLLIGATIVE PROPERTIES

Abstract

Traditional teaching still predominates in schools, especially in Chemistry classes, which are filled with theories and formulas, where the teacher transmits information, and the students become mere receivers. This approach creates a disconnection between the content and the students' everyday lives, leading them to consider chemistry an irrelevant discipline. Additionally, the lack of experimental activities in classes limits active learning. This study aimed to evaluate and propose the use of low-cost experiments and their relation to everyday life to improve the learning of colligative properties. The research was conducted with two second-year high school classes, one from a private school and another from a public school. After the intervention, the questionnaires showed a significant increase in correct answers, highlighting that student became more interested and participatory in experimental classes, resulting in an enhanced understanding of the concepts covered.
