Oficina temática: uma proposta metodológica para o ensino do modelo atômico de Bohr

The research introduced in this paper is a qualitative review and it investigated the apprenticeship of the concepts related to the Bohr atomic model by the students from the first grade in high school during a thematic workshop. In this workshop, there was an experimental activity in which light emission from the electronic jumps which occur in compounds present in lightsticks, bracelets handed out in parties, was presented. The purpose was to associate the assumptions proposed by Bohr to aspects of the daily life of the students. The research was carried out in a high school in the city of Santa Maria, Rio Grande do Sul, Brazil and the results obtained allow us to assert that the developed thematic workshop contributed to the apprenticeship of the concepts related to the Bohr atomic theory.

The Chemistry Teaching through thematic: LAEQUI contributions to the area

The Laboratorio de Ensino de Quimica (LAEQUI) is a research group in the area Teaching Chemistry of UFSM. One of the main objectives of the group is contribute to improvements in education in Chemistry in basic and higher levels. In this work a brief theoretical foundation on the use of the thematic in teaching is presented as well as some research developed by LAEQUI. Yet are discussed the implications of research on learning of high school students and methodological approaches used, addition of group contributions to the area of Teaching Chemistry. At the end of this article some considerations are made about the thematic approach in chemical education, warning to need to move towards a more problem contextualization and consistent with your true feeling.
