A didactic unit was elaborated as a proposal for teaching concepts related to
Electrodynamics, thus starting the studies of Physics. The approach of the theme made
by this teaching unit is based on the concepts of electric current, potential difference,
resistors and Ohm laws, making use and debating the various teaching strategies, such as
texts of scientific dissemination, experimentation, teamwork and etc. Seeking to answer
the question: How can the implementation of a didactic unit, with different
methodological approaches, such as team work, reading of scientific texts and
investigative experiments, contribute to the debate and learning of content concepts
related to Electrodynamics? As a theoretical framework, Davydov's theory of
developmental teaching and Vigotsky's theory of cultural historical learning were used
for all activities. The way it was decided to deal with the problem was to provide
circumstances that are far beyond the mere act of memorizing the content charged in
university entrance exams, turning students into active subjects, or rather protagonists
before the activities proposed to them. Activities were carried out whose performance
evidenced the research procedures and the way science is developed, contextualized
socio-economically and culturally, so that it was possible for students to appropriate the
procedures they used to create the numerous physical theories, in order to understand the
same way as science is done. The activities were developed in a total of eight fifty-minute
classes, with students from the second grade of high school. In order to make it possible
for teachers to understand how each activity was done by students, an analysis of all
material produced based on Bardin's Content Analysis method (1977) was performed.
Directions are pointed through these analyzes, so that teachers who make use of this
material have the possibility to improve their activities. Therefore, the educational
product will be made available to teachers who show interest in knowing or making use
of this material.
