Sequência didática sobre matéria e substâncias: desenvolvimento, aplicação e análise de sua contribuição para o processo de ensino aprendizagem

Abstract

A large portion of high school students struggle to contextualize and relate chemical knowledge to their everyday lives. In this context, in order to overcome the obstacles imposed by traditional education, there has been a growing need to capture students' attention and generate a willingness to learn. Thus, the use of alternative methodologies that make chemistry education increasingly meaningful for students has become essential. With this in mind, the present study developed a didactic sequence focused on the theme of matter and substances. In constructing this didactic sequence, various methodological resources were included with the aim of igniting greater interest in the subject of chemistry among students and making them more engaged and active in the process of knowledge construction. The didactic sequence was designed to span 4 classes, each with two 45-minute periods, and it was implemented at the Dr. Gaspar Vianna State High School across 4 freshman classes. The analysis of the results indicated that the methodology succeeded in sparking students' interest in the subject of chemistry. Additionally, it confirmed the effectiveness of using games and experimental activities in the teaching and learning process, leading to the conclusion that the use of didactic sequences enhances the quality of chemistry education.
