A contextualização do experimento de baixo custo no ensino da física: possibilidades de criar um ambiente para mudança conceitual em sala de aula

Abstract

Positive environments, where the student may develop appropriate experiments in arder to get better understanding of the physical phenomena Qike a good laboratory) are not easily available at the good majority of the schools. Using low cost experiments for teaching physics tum out to be, therefore, an excellent option for exploratory studies. Based on the conceptual change model, we suggest the application of a new methodology in which the low cost experiments become a motivation for learning. In this work one explore, based on this methodology, the topics "movement" and "free fali". Our case study showed that the adopted methodology contributed in a positive way to the learning process, making it possible a conceptual improvement of the students. However, it was not possible to verify the occurrence of conceptual change in a broader sense in the present work.
