A temática cores no ensino de química

Abstract

In this research, we use as study focus the thematic "Colors". The study was developed in two stages, the subjects involved in the first stage are undergraduate students in Natural Sciences of Federal University of Pampa (UNIPAMPA) Campus of Dom Pedrito / RS and in the second stage are the third year high school students in Augusto Ruschi School of basic education localized in Santa Maria / RS. The first stage had as goal to investigate the conceptions of undergraduate students about the thematic Colors by application of an investigative questionnaire with some affirmative, objective and descriptive questions. At this stage, we seek to investigate the conceptions of future teachers, related to teaching and learning processes, the use of thematic, experiential activities and others, as well as to verify the scientific knowledge of them related to the thematic "Colors". The results indicated that the use of thematic in teaching is a good strategy and that the thematic "Colors" is an interesting proposal for use in teaching. Still, we realized the undergraduate students presented difficulties and confusion relation to scientific knowledge related to the thematic. Thus, the difficulties observed in the first stage of this research helped in the preparation of the second. The second stage of the research had goal to investigate the contributions the thematic "Colors" on learning of knowledge related to Science, with emphasis on knowledge of Chemistry through thematic workshops associated with different teaching strategies as: experimental activities and case studies. The instruments used for data collection, pre and post questionnaires, descriptive and illustrative activities, case studies and mind maps were analyzed according to the Discursive Textual Analysis, allowing to detect advances in students learning through proposed thematic approach. Regarding the results, we concluded that the teaching of science was favored using the thematic "Colors" because it allowed that students participated actively in the construction of their own knowledge, and enabled a higher relation of scientific contents with the daily life of students.
