Biomoléculas e citologia: análise de conceitos bioquímicos aplicados no Ensino Médio

Abstract

In Basic Education the most used tool is the Didactic Book (DB), this being a teacher's guide in the classroom. Therefore, it is important to verify if this tool presents interdisciplinary approaches in order to relate the content to the context and reality of the student. One of the great challenges found in teaching is the correct use of DB in order to guide the student in the best possible way. The present work refers to an investigation in DBs of High School Biology, which proposes to analyze the approach of Biochemical concepts with emphasis in the contents of Biomolecules and Cytology. Since Biomolecules are the main constituents of cells, these subjects allow us to ascertain the possible connection between the biological and chemical areas, as well as to verify how the proposed contents are presented in the copies (visual aids, experiments, contextualizations, among others). With this, the topic Biochemistry is presented as a promising theme for interdisciplinary, contextualized and experimental purposes. The methodological processes that guide the present work are organized in three sections, being: (i) characterization of the research; (ii) data source: object of study; (iii) method of analysis and detail of the procedures performed. In order to do so, a review will be carried out in Biology DBs (1st grade), investigating the following criteria: sequence of concepts, number of pages addressing Biochemical content, contextualization, interdisciplinary connection and visual resources. For this, the analysis was organized into five categories. With the analysis, it was possible to verify that the DB under study is a rich tool in approaches, however it should clarify them more, because the DB has significant figures, being that in 46 pages were found 68 figures. Even so, at the time of the chapters there were suggestions of complementary readings, practical activities and in groups. The authors sometimes mention chemical concepts, however, the elements and mentions (presented) are there, however, the explanation Chemistry no. Thus, it is necessary to explore and explain the motive and the relation of such elements to be present in that space / figure / text, so that the student makes the interdisciplinary relationship between the two areas of knowledge. Finally, it is hoped that with the development of the research it will facilitate discussions about the theme and quality of DBs in Science and Biochemistry Education.
