Ensinando o conceito de campo elétrico a partir do fenômeno do raio
Abstract
This dissertation is a report of the development and application of a Potentially
Meaningful Teaching Units (PMTU), proposed by Moreira, approaching the
concept of electric field for high school level. Aiming to contextualize it, the
starting point of PMTU is the lightning phenomenon, which is difficult to
reproduce at the school lab, is worked with digital educational objects (DEO)
and the students were engaged actively in all activities, showing great
motivation to study the phenomenon and learn the concepts involved. The
construction of conceptual maps by the students with collaborative ways, also
allowed them to interact socially, trying to negotiate meanings. The theoretical
basis of PMTU uses mainly the Theory of Meaningful Learning of Ausubel. The
results gave evidence of the occurrence of significant learning by students, and
the acceptance regarding the strategies used.
