SUMMARY:

The general objective of this research was to investigate the use of manipulative materials in the teaching of Descriptive Geometry, seeking to understand their contribution to the teaching and learning of geometric concepts. To achieve this goal, we specifically established the following objectives: to develop a didactic sequence that could facilitate the appropriation of knowledge; to produce an activity book with the practices developed and consolidated; to analyze students' perceptions of the teaching of Mathematics and the production of their knowledge, based on the use of manipulative materials. The guiding question was: How can manipulative materials favor the understanding of concepts of Descriptive Geometry? The research was based on the hypothesis that the process of teaching and learning Mathematics, when based on meaningful learning through manipulative materials, could promote a positive attitude, awaken interest and improve students' performance in this subject. The study was motivated by the need to experiment with more effective teaching strategies to promote students' understanding and interest in Mathematics, especially in view of the lack of motivation and difficulties observed in the learning process of this area, often associated with the inherent complexity of the content. The research was conducted with a third-grade high school class from a state public school in the city of Natal, RN. The process involved the use of manipulative materials to facilitate spatial visualization and understanding of orthogonal projections. Data were collected through audio and video recordings, focus groups, and field diary notes, and were analyzed qualitatively. The results indicate that the use of manipulative materials contributed to increased student engagement and motivation, in addition to favoring the understanding of the concepts worked on. It was observed that the concrete manipulation of geometric solids provided a better perception of the relationships between orthogonal views, helping in the transition between three-dimensional and two-dimensional representations. However, some challenges were identified, such as limitations related to time management for executing the activities. Based on these observations, it was suggested that the activities be reorganized into smaller stages, aiming to optimize time and favor monitoring of student development. Data analysis allowed us to conclude that the use of manipulative materials, combined with strategies that integrate theory and practice, favors the development of skills related to spatial visualization, understanding of orthogonal projections and geometric reasoning. Thus, the initial hypothesis, that the application of these resources could promote a positive attitude and improve students' performance in Descriptive Geometry, was confirmed by the results obtained.
