The main objective of this work is to propose an efficient approach of the electric field
concept so that it will be done considering that the education area lacks about efficient
approaches related to the proposed theme. The electric field theme was used,
considering that the students have several difficulties in their comprehension, though it
is worth noting that their comprehension must be associated with a good
contextualization for the Physics teaching. For the execution of our proposal, we
selected a 2nd year class of Integrated Technical Education in Electrotechnics course at
Federal Institute of Amazonas, Manaus Centro Campus. The respective class in the 1st
year had already studied “Electric field” through the Technical discipline called
“Electricity”, however the students had several difficulties on the subject, it was detected
through the answers presented by the students through an initial questionnaire.
Therefore, in order to fill this gap, we planned an expository lecture about electric field,
developed with experiments assistance. Based on the experimental practice, we used
some experiments, such as Electrostatic Generator, Magnetism Kit (field lines), through
these materials, it was possible to make an analogy for the conceptual understanding
of “Electric Field” theme with the support of the elaborated presentation. With the
perspective to enhance students' learning related to the subject understanding, we set
up the “flat capacitor” experiment coupled with the “electrostatic generator”, in which we
emphasize that this experiment was used in order to make the learning much more
meaningful. After this step we applied a final questionnaire to analyze the contribution
in terms of knowledge in students´ understanding. Our proposal was based on Jerome
Bruner's constructivist theory, which has as its intermediation process the educators´
role as a fundamental factor not only transmitting, but also related to the interpreting
culture. The proposed activities, in this research take in consideration the teaching by
discovery and the proposal of a spiral format curriculum, in which the content is
proposed superficially and in depth according to the student's learning.
