A construção do conhecimento em matemática através de estratégias diferenciadas em um curso técnico em agropecuária

Abstract

This research developed in PPGEA / UFRRJ as dissertation, we made a reflection on the teaching and learning of school mathematics emphasizing some teaching experiences that value abstraction, memorization, with content outside the reality of students, and in this context we enter the vocational education field in Brazil this perspective, think of as research problem: what strategies can be used for the teaching and learning of school mathematics contribute to the improvement of knowledge of the field professional? To contribute to this problem, identify the main difficulties encountered in the teaching and school mathematics learning in the professional technical course and research some methods in which these processes can significantly occur. We work with two groups of technical progress in agriculture, a control and the other experimental, that this work will treat as a field class to accomplish comparisons. We applied to two classes a pre-test to identify some difficulties in relation to the geometry of content and arithmetic, a questionnaire diagnosis and post-test. We also point may need to know what knowledge the students had about multiplication and division. The diagnostic questionnaire allowed us to check, missing school students, a considerable amount worked and some considered the school mathematics teaching offered in decontextualized and fragmented way. We performed for the two lecture classes with the help of video lesson. Then and only for the country group proposed a field of activity in which they measured the dimensions of the ponds and flowerbeds of the institute, they found the area available for planting as well as the outline of the region and measured the spacing between the vegetables planted in the flower bed . This activity aroused enough student interest and questions. After this activity, we applied one after posttest results of a questionnaire. We verified that followed the lectures of field classes improve the students' knowledge. We emphasize that we can make a difference to improve school mathematics teaching, with dynamic lectures and contextualized when accompanied by practical classes held outside the classroom context. We alert for the importance to the technical experience school mathematics in professional activities making it significant.
