Objetos virtuais de aprendizagem aplicados ao ensino de física: uma sequência didática desenvolvida e implementada nos conteúdos programáticos de física ondulatória, em turmas regulares do nível médio de escolarização que utilizam um sistema apostilado

Abstract

The use of digital learning objects (DLO) in the classroom has become more relevant and frequent. Therefore, reflecting on pupils and teacher s attitude, in real-class situations about the insertion of new educational technologies has proved pertinent and up to date. This paperwork presents a didactic sequence about Physics of Waves using mainly PhET Interactive Simulations. The methodological approach is based on the Meaningful Learning Theory by Ausubel and coworkers and the Face-to-Face Collaborative Method developed by Moreira. The sequence was applied in two Physics classes of two different Brazilian High Schools which use a Teaching Structured System. All the activities are designed in the form of a preliminary, Interaction with the DLO, and outcome and planned for double 45-minute classes. The continuous use of Maps of Concepts in order to follow the evolution of concepts understanding of the student has allowed to conclude that there have been effective learning gains in the process of hierarchical organization and relationship between the concepts involved in the Physics of Waves. The work described here has shown that it is possible successfully insert DLO in the regular classrooms of a traditional private school. However, the most important result from this work has been the change in the attitudes of students and teacher and their behavior in the classroom. After this practice, the teacher has planned the classes more carefully, introducing new teaching initiatives, and the students have experienced a more active and protagonist role in the process of knowledge building.
