Alisamento capilar: uma temática para a abordagem de proteína

Abstract

Considering the importance of knowledge about science and how it helps active and responsible participation in atual society, the present study aimed at detecting and evaluating the previous and subsequent knowledge of the didactic proposal that involved the hair straightening theme in the understanding of protein concepts. 27 academics of the 5th semester of the Graduation in Natural Sciences participated in this research being the didactic proposal applied and evaluated through a questionnaire, expository class, demonstrative experiment and resolution of a case study. In order to evaluate the answers present in the questionnaire, the questions were classified into two dimensions: 1st dimension, chemical knowledge of proteins; and the 2nd dimension, relation between hair straighteners and Biochemistry. Student’s answers were classified into categories corresponding to each degree of satisfaction, such as: SR (satisfactory response); PR (partial response); RU (unsatisfactory response) and NR (no response). As a result of this study, it was detected that the academics presented difficulties in understanding the concepts of proteins, even after exposure to proposal activity, demonstrated by the high PR index (37 responses) in the 1st dimension. Indeed, there was poor clarity in the responses’s development, which confirms the difficulty specific knowledge of Biochemistry. However, in the second dimension, data were satisfactory, since most of the answers obtained are in the SR category, with 70.5% in the pre-test and 85% in the post-test. Possibly, these data was obtained, because it is a greater approximation of the reality of the subject with the biochemical concepts. Data from the presented study demonstrated 18.5% SR, 74.1% PR and 7.5% RU, being the best result of the present study. Finally, part of this work validates the efficacy of thematic activities allied to daily topics, this confirms data already present in the literature. However, more studies are required to supply the understanding of cientific protein concepts, because the present proposal did not show improvement in this context.
