A física e o meio ambiente: construindo os conceitos de estados físicos da água, de mudanças de estado e de ciclo da água pela integração de uma atividade experimental com uma atividade computacional

Abstract

In this work we evaluated the integrated use of an experimental activity (EA) and a computational activity (AC) as mediators resources to promote learning of the concepts “physical states of water”, “changes of the physical state of water” and “water cycle” by students in the 4th year of elementary school. The goal was to work the physics concepts making use of the Science, Technology, Society and Environment approach. In order to systematize the knowledge produced, the study set out to develop a field activity. In order to investigate such problem it has been conducted a qualitative research making use of questionnaires, semi-structured interviews and a daily class journal. The historical and cultural perspective of human development, in particular, served as a guiding reference for this work. The results show that the development of such didactical sequence, based on a multimodal environment, using two resources in an integrated manner, promoted more effectively the learning of the concepts “physical states of water”, “change the physical states of water” and “water cycle” by students in the 4th year of elementary school.
