Um estudo dos avanços conceituais dos estudantes sobre calor e temperatura decorrentes da aplicação de uma estratégia de ensino inspirada na teoria de Lakatos

We report here a study about the application of a formal teaching strategy about heat and temperature concepts applied among high school students. The strategy belongs to a research trend which deals with epistemological analogies and has an innovative character related to the students’ preparation for rational debates between conceptions and/or rival theories, using didactical rational reconstruction (DRR) which aims to help scientific concepts rational learning. We investigate the outcomes of this preparation and students’ conceptual development, analyzed through a qualitative-interpretative methodological approach.

O tratamento probabilístico da teoria cinética de colisões em livros de química brasileiros para o ensino médio

This paper presents and discusses an analysis of the approaches and the didactic treatment of the kinetic model of collision between particles in chemical reaction (collision theory model) presented by brazilian chemistry textbooks for the medium level. Our starting point at this search was the correct and scientific model for this theory which is based on random events, but most of all the books investigated does not consider this fact like an important and very precious didactic aspect. We utilized in the investigation the writing discoursive analysis technique.

As atividades de demonstração e a teoria de Vigotski: um motor elétrico de fácil construção e de baixo custo

The experimental demonstration is one of the traditional activities used in the ambit of the Science teaching and of the scientific divulgation. However, this activity has not been fully explored yet in the classroom, because teachers have faced considerable difficulties due to the lack of demonstration equipment. In this work we present the explanation of an easy and low-cost assembly of an electric motor, to be used in Physics classes in High School. In addition, we employed Vigotski’s theory to guide this experimental activity in the classroom.
