O uso da prática experimental no ensino da dilatação térmica dos sólidos como ferramenta metodológica

Abstract

In this paper we describe the dynamics of the application of a Teaching Project in Physics. Based on this assumption, the work aims to evaluate the feasibility of using experimental practices in teaching phenomena related to the thermal expansion of solids in order to promote meaningful learning. The study object was two 2nd Year classes (morning and afternoon) with a total of 63 students and the Federal Institute of Piauí-Campus São Raimundo Nonato-PI. The research was qualitative in nature, with the intention of obtaining a positive expression regarding the use of experimental practices as a teaching tool, while emphasizing that the data analysis assumes a quantitative character. Initially, a questionnaire was applied to assess the students' previous development regarding the content that would be covered. Then, the types, characteristics, and some practical applications of thermal expansion were explained. After that, the practical part was presented to the students by means of three low cost experiments. Finally, the same questionnaire was reapplied as in the beginning, in order to analyze the students' evolution regarding the teaching methodology used. Based on the data analysis generated through the questionnaires, a significant increase in student learning was observed with the methodology used. Therefore, we conclude that the results achieved were extremely satisfactory.
