Compactação do solo: contextualizando o ensino de Física no curso técnico em agropecuária

Abstract

The finding that the teaching of physical discipline in Brazil, still practiced in a decontextualized, deficit reflects a training for students of agricultural colleges. This fact shows that the teaching of physics is still emphasized the memorization of formulas and numerical applications simply that the concepts are transmitted without taking into account the reality of everyday life and the prior knowledge that students bring in their cognitive baggage. This practice makes physical discipline, especially in agricultural technical schools, alienated with regard to social, environmental, technological and political. And that is detrimental to the training of future technicians, it is necessary that they leave with full training, that is, oriented training for citizenship, autonomy and strengthening the learning to learn. Changing this problem is possible when one takes into account that physics needs to be worked falling off of certain standards of educational references, emphasizing the search in contemporary epistemologies that takes into account the context, interdisciplinary, meaningful learning and research methodology. This study was conducted at the Federal Institute of Science Technology Education Para/Castanhal Campus with students from a class of second grade of High School Integrated Technical Course in Agriculture. The research aimed to verify how the teaching of physics can help to contextualize the study of soil compaction on the technical course in agriculture in the IFPA/Castanhal Campus, to improve their performance and making the subject look pass in a different light. A vision of teaching physics is present in their daily lives. The qualitative study was carried out by developing a proposal for analyzing data that were obtained through questionnaires, seminars, tests and activities in soil physics lab and field. The questionnaires with open questions about the subject matter physics and soil compaction before the survey showed that most physics students could not see with good eyes, that is not liked and they were not attractive and demonstrated ignorance of the subject soil compaction. During the activities, has changed the attitude of students regarding the physics and soil compaction. The questionnaires at the end of the research showed that the path to be followed to reduce the distance that separates the contents of physics and technical disciplines of running through methodologies that emphasize contextual, interdisciplinary, meaningful learning and design methodology. The seminar, the activities in soil physics lab and field stressed the need to stray from the traditional teaching. Thus the research sought to apply the context from a theme generator that is "solo" whose purpose was to investigate the degree of compaction of different areas of the managements of the Castanhal Campus IFPA. And establish the relationship between the basic concepts of physics and soil science, noting that they are the same.
