Qubism 3d Modeling in Teaching Orthogonal Projections

Education benefits from the globalization of effective tools that facilitate student learning. Education in Mozambique is still traditional without any technological resources, such as computers, data show, applied software and smartphones. This traditional model drives some difficulties in 3D perception in technical drawing (TD) subjects. Technological tools with 3D visualization allow the enhancement of the learning process in an interactive and innovative way, giving the teacher the power to select the most appropriate technological resource for the desired subject. Qubism 3D modeling (Q3DM) and the cube test (CT) are the technological resources selected for this study, as they present usability features capable of promoting 3D spatial skills in the study of orthogonal projections (OP). The research was conducted in a secondary school in southern Mozambique, it is a quasi-experimental case study, supported by a mixed quantitative and qualitative approach. The instruments used were a pre-test and a post-test applied to two groups of students; one experimental and one control. Fifty students solved practical exercises on OP and their level of spatial visualization was measured with the CT. The study aims to investigate whether the use of Q3DM as a teaching-learning tool promotes 3D spatial visualization of objects in the context of technical drawing. From the analysis of the CT results it is inferred that the students who used Q3DM had better results on the cube test.

Technologies came to revolutionize the teaching of technical design; they brought resources that enabled 3D and 2D graphic simulation. The objective of this research is to understand how the implementation of the dynamic software GeoGebra on the topic of cylindrical sections can improve 3D spatial visualization in students because of the challenges in understanding the 3D representations and transporting them to the 2D sheet. This is a quasi-experimental case study in a mixed qualitative and quantitative approach which was conducted in a grade 12 class on the subject of descriptive geometry. The instruments used were a pre-test, post-test and Santa Barbara Solids Test. The students of the experimental group used GeoGebra and obtained better results in the post-test than the students in the control group, which suggests an improvement in learning; however, the Santa Barbara Solids Test results showed that the difficulties in visualizing views of the projected solids in a two-dimensional plane persisted. This study is also intended to test software in a classroom with students who have never experienced a 3D technology in their educational practices and direct future research in the complex content of descriptive geometry with the help of software.
