Roteiro de atividades experimentais com materiais de baixo custo: uma proposta para o ensino de Eletroquímica

Abstract

The traditional teaching method no longer meets the educational demands of today and experimentation has been identified as a fundamental didactic strategy to make teaching more meaningful. However, chemical education professionals have faced several obstacles to work with experimental practices, due to the school reality of the Brazilian basic network. Therefore, the present research aimed to build a script of experiments with low-cost materials for the teaching of Electrochemistry and evaluate its potential as pedagogical support material by making this material available to 08 high school teachers who teach in schools. of the Public Network in Picos Piauí. The script has a brief presentation, some of the essential safety standards in the "laboratory space" and the electrochemistry content that is organized into 4 chapters, where each chapter addresses a subtopic of this content, presenting a brief introduction, the title of the experiments, the objectives, the materials used, the experimental procedures and suggestions of questions for the analysis of the student's learning. The research method used was a qualitative exploratory and quantitative approach, using as data collection instruments a questionnaire with closed questions and multiple choices in order to identify the main difficulties of teachers in relation to experimentation and the relevance that they attribute the proposal of constructed didactic material. From the analysis of the results, it appears that the script constitutes a relevant tool to help teachers, thus facilitating their work and motivating them to insert the experimental approach in a more representative way in their pedagogical planning
