Experimentação investigativa com materiais alternativos no ensino de química: proposta metodológica aplicada em uma escola de Cocal

Abstract

The main objective of this research was to insert the proposal of investigative experimentation with alternative materials as a teaching methodology, aiming at facilitating student learning. The use of alternative approaches, such as demonstrative, illustrative, descriptive and investigative types of experimentation, is a strategy capable of making the teaching process more attractive and effective, in addition to stimulating the development of critical thinking in students. In this sense, classes based on investigative experimentation played a fundamental role in promoting knowledge and motivating students in relation to the discipline of Chemistry. However, it is worth mentioning that this research adopts a field approach, in which diagnostic questionnaires were applied to obtain information about the students and their conceptions in relation to investigative experimentation, as well as experimental classes and analysis of forms filled out during the application of this methodology were analyzed. These forms and questionnaires were the tools used to assess the knowledge acquired by the students through the use of the proposal. The results showed that investigative experimentation with alternative materials in the teaching of Chemistry is a viable and effective methodology
