Utilização de experimento confeccionado com materiais de baixo custo como ferramenta metodológica no ensino de física

Abstract

We analyze the process of teaching and learning physics in two classes a 2nd year and one of the 3rd year of high school with thirty (30) students. We use qualitative experiments made with inexpensive materials, as a methodological resource for improving school performance. Track which were the previous conceptions of the students on the topics covered in class, then use visual aids to do introduction to the concepts studied. We also use an approach of themes using concept maps, emphasizing the ramifications of the concepts involved, always finishing classes with a summary of what was discussed. We evaluate the learning gain of students for 20 (twenty) classes, for this, we use qualitative questionnaires every two (02) classes. We observed a significant increase in school performance in the class, using data obtained from the evaluation questionnaires and engage students in activities in the classroom.
