CTS no contexto do novo ENEM e do ensino de química

Abstract

The National Secondary Education Examination (ENEM), established in 1998, has become, over the years, the main process of evaluation of Basic Education in Brazil, projecting itself as an important element of dissemination of new educational values. The concept of evaluation incorporates a proposed evaluation of the development of skills and core competencies to the full exercise of citizenship, one of the STS approach objectives, through interdisciplinary items involving secondary education subject knowledge, in which chemistry is inserted. In this context, this qualitative research aimed to analyze, based on the assumptions of the STS curriculum perspective, the relations between the skills and abilities (C & H) of Natural Sciences and their ENEM Technologies (CNT) with questions associated with Chemistry education of this examination in the period 2009-2015 (new ENEM) and the factors that influence these relationships. The exploratory reading of documents and scientific papers on the Enem and on STS, as well as my teaching experience, allow me to infer, a priori, the existence of some level of approximation between the STS focus on documents and Enem questions. This perception instigates me to research how and to what extent this occurs. Therefore, we investigate how occur the approximations between the theoretical assumptions of the STS approach with the CNT competencies and skills and the questions associated with the teaching of chemistry applied in the new Enem. For this, we must ensure that the competencies and abilities have associations with the theoretical assumptions of the STS perspective, in addition to analyzing the content and structure of the questions associated with the chemistry teaching, examining whether and how it occurred to approach these issues with the STS educational perspective principles and what conditions determine the mediation of this proximity relationship. To obtain the information it was used three data collection techniques: observation, verification of official documents of the Brazilian education and analysis of questions applied to the new ENEM. As question analysis tool it was used the Textual Analysis Discourse (TAD). Excerpts from interviews with teachers question makers from UFPA were utilized to support the discussions of the results obtained. The results showed that whereas C & H Natural Sciences and their Technologies have a strong association with the assumptions of the STS educational perspective, the new 11 ENEM questions present approximation at different levels from the theoretical framework of the STS approach. The results also showed that among the 156 analyzed questions, and which are associated with the teaching of Chemistry, those with the highest occurrence are those that do not provide this approximation. We conclude that the affinities between the natural sciences competencies and skills and their Enem Technologies with the issues associated with the teaching of chemistry for this examination, in relation to the STS approach, occur insufficiently for various reasons, and factors such as for example, the educational model in Brazil, the traditional formation of teachers question makers and the little understanding of this curriculum conception converge for this lack of concordance. Although it is evident the need for greater linkage of the questions with the STS approach, this research seeks to provide contributions to a more meaningful chemistry education and provides a detailed analysis of the Enem chemistry items, aiming to subsidize the construction of questions with knowledge that get closer to the STS educational perspective, which constitutes a strong current trend in the teaching of Chemistry and Natural Sciences.
