Abstract

The effects of three pedagogical activities concerning their effects on the development of spatial visualization skills are presented in this study. Those activities are based respectively on the interpretation and generation of technical drawings, wireframe models, and finally on the generation and interpretation of solid models. In the third activity it has also exercises where numerical controlled machines are used. The activities were applied to a group of under-graduate students in the form of short courses, and the results were measured by MRT testing. The crossover experimental design was used to organize the order of activities and to facilitate the drawing of meaningful conclusions. The statistical analysis was performed according by Bayesian methods. It is concluded that the activity that uses applications of technical drawings has more potential to develop spatial visualization skills. (AU)
