Unidades de Ensino Potencialmente Significativas (UEPS)em Ambientes Virtuais de Aprendizagem (AVA) como instrumento de aprendizagem significativa de física no ensino médio

Abstract

This work uses Potentially Meaningful Teaching Unit (PMTU), the instructional strategy proposed by M. A. Moreira, in a Virtual Learning Environment (VLE) in the Moodle platform, as a tool for learning physics in high school, through an instructional sequence. The AVA has been configured according to the sequence of PMTU. The sequence consisted of applying a diagnostic evaluation, use of previous organizers, initial presentation of problem-situations involving simulations of the site Interactive Simulations (PhET), review and theoretical restatement of the problem-situation at higher level of complexity, individual summative evaluation, the final lecture and assessment of learning. This sequence was developed through activities in the classroom and extra classes. The theme worked throughout the sequence was the physics of flight, and the contents discussed were the principles of dynamics and Bernoulli's principle. From the beginning it became clear the connection between the instructional sequence based on meaningful learning and the potentiality offered by a Virtual Learning Environment: the first one guiding the activities and the second providing a backdrop for their development of the student, aiming at the critical (re)construction of new knowledge. The content was presented in different formats, varying from traditional viewing videos and reading texts in the classroom, for the use of various features available in Moodle VLE, such as the use of PhET simulators, participation in forums, production of online texts among others. Performed the analysis of the results presented by the students after the migration from traditional teaching methods for the PMTU methodology based on the combined use of the VLE Moodle, it was observed significant increase in the student performance measured by the grades obtained by the students in a given quarter in comparison with the previous one. The results show that the method provides learning more dynamical, comprehensive, and participative and in tune with the technological resources that are part of their reality.
