O estudo de caso como metodologia ativa de aprendizagem no ensino de reações químicas.

Abstract

Chemistry education plays a fundamental role in student's formation, providing them with knowledge about the properties of matter, chemical transformations, and the relationship of chemistry with the world around them. However, traditionalist teaching of chemistry, based on passive transmission of information and emphasis on memorization of concepts, has often been criticized for limiting students' understanding and demotivating them towards the subject. in this context, this study aims to analyze the contributions of the case study approach in chemistry education. The research was conducted in a 3rd-grade class of high school at Ecit Adilina de Sousa Diniz, employing a methodological approach in three stages. in the first stage, the theme was introduced through questionnaires to assess students' prior knowledge. In the second stage, practical teaching activities were developed using the case study methodology, applying the case of "miraculous mixture." finally, in the third stage, a new questionnaire was administered to evaluate participants' progress in knowledge after the implementation of the teaching methodology. the results obtained indicate that the use of the case study approach in chemistry education provided a more meaningful and contextualized learning experience. students were able to relate chemical concepts to everyday situations, stimulating their curiosity, critical thinking, and active participation in the learning process. this methodological approach proved to be effective in promoting a deeper understanding of chemical content and contributing to the development of essential skills such as problem-solving and informed decision-making.
