The Qubism 3D modeling simulator (Q3DM) was used as an aid in teaching visual representations of Orthogonal Projections (OP) in the 1st Cycle of General Secondary Education [1]. This study demonstrates the applicability of this type of computer simulator in teaching the technical design content. This simulator allows to obtain real and motivating representations, it also has the advantage of allowing the manipulation of the image to obtain a representation with imaginary auxiliary lines parallel to the projection planes. The Visual Education discipline is one of the subjects in which students from the 1st cycle of General Secondary Education in Mozambique express less interest; in the opinion of these students, the contents are difficult to understand due to the abstract concepts that are used [2]. In this work, it was investigated whether the Q3DM simulator can help in the development of skills in students regarding the process of connecting the abstract/imaginary to the concrete / real. The purpose of this research was to use the software Q3DM to identify the three orthogonal views of given pieces; visualize the abstract graphical representations and check if the Q3DM simulator helps to clarify the visual representations of the OPs. The methodology used in the investigation was a quasi-experimental design without control groups to demonstrate causality between an intervention and outcomes [3]. A single pre-test measurement is taken, an intervention is implemented, and a post-test measurement is taken. This quasi-experimental design study use both pre-test and post-test measurements as well as nonrandomly selected control groups. The results indicate that it is possible to classify the visual representations of OPs using the Q3DM simulator [4]. The results also suggest that the use of simulators in Visual Education classes can be a very useful tool to encourage, motivate and improve students' academic success in this discipline.
