Abstract

This paper examines how a teaching intervention, focusing on the relationship between the period of a simple pendulum and its length, can improve the understanding of oscillations in 71 sixth-grade students. The intervention was carried out with the help of sensors equipped with smartphones and the "Phyphox" application. To collect data, students were given a questionnaire before and after the intervention, and then the responses were analyzed using the three-tier test. The results showed that the teaching intervention had a substantial effect on changing students' alternative perceptions of this topic.
