Abstract:

The world is increasingly connected to information and communication technologies (ICT), it is almost impossible not to notice the presence of technologies around us, including in education. Technologies enable teachers to discover and develop more motivating and effective teaching and learning methodologies, making the teaching-learning process more dynamic, interactive and student-focused. Several free technological resources (RT) are currently available that can be used as tools to aid in the learning of Technical Drawing (DT) due to the fact that they allow and develop intuitive understandings of abstract phenomena. The aim of the research is to present GeoGebra simulations to help solve students' 3D spatial inability, promoting spatial learning in Descriptive Geometry (DG). Overall, secondary school students in Mozambique have difficulties in imagining objects in 3D, which makes it difficult to represent them in 2D. The research is a case study conducted with secondary school students, in a quantitative approach, a pre-test was applied in two groups, one experimental and the other control, the sample was randomized. The results were satisfactory, the students showed a development of skills in 3D spatial visualization and a taste for technology. The research brings contributions to teachers by bringing the smartphone as a tool that develops 3D spatial reasoning.
