Uma proposta de plano de unidade para o tema energia por meio de uma abordagem CTS&A

Abstract

The objective of this work was to elaborate, develop and evaluate a unit plan for the study of Energy using a critical theoretical and methodological perspective of teaching and learning with a focus on the CTS & A aspects. We use as theoretical reference the theory of Meaningful Learning, Conceptual Maps, CTS & A relations, Physics Teaching and the use of the Unit Plan in the teaching-learning process. We conducted a qualitative research, applied in a first year high school class composed of students between fourteen and fifteen years of age, located in a college of the state education network of Paraná, in the municipality of Tapejara. After the elaboration of the unit plan, we sought to collect the data for our research from the various activities that we use as collection instruments. The data were analyzed by comparing the application of the instruments before the intervention and after the proposed intervention through work with the unit plan. In this way, we establish categories of analysis for each of the data collection instruments used. With the analysis we found that in all activities, students in general have made significant progress. For example, in the comparison between the initial and final conceptual maps, we found that students evolved in all established categories. Considering the initial and final questionnaires, we saw that all the questions proposed, there was a marked improvement in the identification of the different energy types, as well as their actions and transformations. In view of the results obtained, we can see that the objectives listed were achieved, since they point out that the intervention promoted by the unit plan was successful in discussing Energy significantly through the assumptions of the theory of Meaningful Learning.
