Promotion of spatial visualization with GeoGebra and Qubism 3D software; [Promoção da visualização espacial com os softwares GeoGebra e Qubism 3D]

By Chivai, Cacilda H.

Technology has driven new forms of teaching and learning with applications adapted to the various technological resources. For the discipline of Technical Drawing and Descriptive Geometry, technology has brought computer simulations that allow the visualization of experiences in 2D and 3D environments. In Mozambique, teachers adopt a traditional teaching method, without using technological resources, which can make it difficult to understand the content related to Orthogonal Projection and Cylindrical Section. However, in this study, we employed simulations using the Qubism 3D modeling software, as well as the GeoGebra dynamic geometry software, adapted for smartphones. Computer Simulations allow the construction of geometric elements in a dynamic way. For this reason, the objective of this research was to apply spatial visualization tests to verify whether the two software programs mentioned really facilitate the learning of the topics Orthogonal Projection and Cylindrical Section. This study was motivated by the fact that secondary school students have difficulty in spatially perceiving 3D representations and their transposition to the 2D drawing sheet. It was a quasi-experimental case study, in a mixed qualitative and quantitative approach, whose instruments used were pre-tests, post-tests, the Cube Test and the Santa Barbara Solids Test. A total of 100 students involved, randomly distributed in groups (experimental and control). From the analysis of the results of the application of the spatial visualization tests, the data suggest that the students developed spatial cognitive skills. The data also indicate that the Qubism 3D Modeling applications and the GeoGebra dynamic geometry software promoted spatial visualization skills in the experimental group. The research leaves open future investigations for applicability of technological applications in the study of various other subjects in the disciplines of Technical Drawing and Descriptive Geometry.

Qubism 3D Modeling and Geogebra: suitable softwares to promote 3D visualization in the topics of ortogonal projections and cylinder sections; [Qubism 3D Modeling e GeoGebra: softwares adequados para promover a visualização 3D nos temas de projeção ortogonal e seção de cilindros]

By Chivai, Cacilda Helena

In General Secondary Education in Mozambique, the use of technological resources for learning Technical Drawing and Descriptive Geometry is still rare. The aim of this research is to see if Qubism 3D Modeling and GeoGebra software simulations, in the subjects of Orthogonal Projection and Section of Cylinders, contribute to improving students 3D spatial visualization, considering students previous difficulties in this type of skill. For the study of Orthogonal Projections, we adapted Qubism 3D Modeling to help clarify the representations of orthogonal views. For the study of cylinder sections, we used the dynamic geometry software GeoGebra, as it facilitates the perception of the shape of the figure resulting from the section. This is a quasi-experimental study, following a qualitative approach, conducted in a school in southern Mozambique. The techniques employed included observation, note-taking and photographic records, and the instruments used were satisfaction questionnaires. Fifty students took part, 25 of whom tried out the Qubism 3D Modeling software and the rest used the GeoGebra software. These students solved practical exercises in Technical Drawing and Descriptive Geometry during the didactic intervention. The analysis of the results suggests that the students developed spatial visualization skills, and the data also indicates that the software applied promoted significant learning, making it possible to verify the learning resulting from the computer simulations. From the research already carried out, there are some curiosities and perceptions that can serve as a bridge for further research into the applicability of technology in the study of various subjects in Technical Drawing and Descriptive Geometry. © 2024 Lundiana.
