O Produto Educacional as Contribuições de Dalton para o Ensino de Química: o que Dizem os Professores de Química da Educação Básica?

Abstract

The teaching of Dalton's model is still a challenge for teachers of basic education, because, generally, it is limited to the mere presentation of the model or even to a simplification of this model through analogies. Thus, the present work aimed to produce the educational product "Dalton and his contributions to the teaching of Chemistry: a proposal of didactic guide" and evaluate it by teachers of Chemistry of basic education of MS. The educational product was constructed based on the concepts of active learning methodologies (MAA) with emphasis on the Problem-Based Learning Methodology (BPA). The proposed educational product is configured as a didactic guide and presents, in a differentiated way, the approach of Dalton's main contributions to Chemistry, offering the teacher diversified activities. The research on the approach was qualitative without intervention. The data collection instruments were two questionnaires, the initial and the final, the first aiming to raise the profile of the teachers participating in the research, and the second, to investigate the view of chemistry teachers about the educational product. Based on the results of the research, it is possible to infer that teachers contributed significantly with didactic-pedagogical questions, in-depth discussions about the History of Science, about the epistemology of science and issues related to the daily life of schools. Regarding the potential of the evaluated material, the teachers view potentialities as presenting other contributions of Dalton other than the representational model of the atom, the dynamicity of the material with the presence of links and QR Codes that facilitates the handling of the material and the way the material is presented. Finally, we defend the necessary participation of teachers who are teaching in basic education for the evaluation of educational products as a fundamental step in the preparation of teaching materials.
