Teaching by investigation. Simple harmonic motion. Physics Teaching.
The present work aims to present a teaching proposal with an experimental practice, using an
educational product developed for the study of simple harmonic motion, elastic force,
gravitational acceleration and viscous resistance. In the course of our research, we used teaching
and research methodologies such as Meaningful Learning, Inquiry Teaching, Mathematical
Modeling and Positive Heuristics. Didactic sequences were developed and applied to the
educational product, where it was possible to observe the performance and participation of
students during the proposed activities. In addition to that, a statistical analysis was carried out
with the grades obtained by High School students in the evaluations proposed in the classes of
the 2nd year A and 2nd year B of EREM Augusta Cordeiro de Melo, located in the city of
Calçado, in the Agreste region of Pernambuco, Brazil. In this analysis, we verified that
statistically there was no evidence of better performance among the students of 2nd year A that
participated in the experimental activities and those who did not. On the other hand, for the 2nd
year B, it was possible to verify that for a significance level of 15% there is evidence that the
performance among the students participating in the experimental activities was better than the
students who did not participate in the activities.
