"2 or 3d - you in action"

construction, validation and application of an educational game for teaching molecular geometry

Abstract

Much has been said about the challenge of teaching chemistry and it is clear from classroom experience that some content is more challenging than others in the teaching process, such as molecular geometry. This has led to the need to formulate alternative methodologies, giving students the opportunity to develop the skills and competences needed to build their knowledge. With this in mind, the aim of this article is to describe the stages of construction, validation and application of the didactic game "2 or 3D - You in Action", made from alternative materials in order to verify and assist the learning of molecular geometry content in a second grade high school class. This research was described and the data was collected using semi-structured questionnaires, which were analyzed using the inductive method. The results point to the relevance of the game as an auxiliary tool in the learning of molecular geometry, since it allows interaction and cooperation between the teams, encouraging them to transfer knowledge and, above all, to learn from mistakes, exploiting their protagonism and favoring learning.
