Análise e aplicação de atividades sobre estrutura atômica na perspectiva CTS e ensino por investigação

Abstract

The research was conducted by analyzing the chapter on atomic structure of the textbook Chemistry 1 book Year of the authors Mortimer and Machado (2013) after reading the chapter were found 6 activities that were reviewed for the presence or absence of aspects that show the education for research as well as the CTS approach. In the first stage the analysis of the criteria was built from a categorization that classifies activities as the presence or absence of these from the considered theoretical. We found a few aspects related to these approaches in the analyzed activities, which was expected because the work has not been built in this perspective, but in constructivist perspective. In the second stage an activity that contemplates and emphasizes aspects of teaching by research and CTS approach built by Bonfim, Silva and Amaral (2013), was applied in groups of nine years of basic education II. The application showed that the dynamics of working in CTS approach follows own ways that require time and space as described in the theoretical framework.
