Outils numériques dans l’apprentissage de la conception mécanique : analyse des liens entre représentations externes et capacités visuo-spatiales dans le processus de conception

Abstract : In a co-located mechanical design activity involving learners, are the actions undertaken and the external representations mobilized related to their spatial skills? Through this question, our study explores the characteristics of the ongoing process in the co-located collaborative mechanical design activity in relation to the spatial skills of the learners and the characteristics of the external representations with which they interact. We address the question in a descriptive aim by analyzing the situation under a prism inspired by distributed cognition. Thus, we retain an individual socio-cognitive dimension and an interactional socio-technical one. The first relates to human agent’s traits and the second to human interactions, including the ones with external representations. This work is based on test measurement of spatial skills of 63 Senegalese, bachelor and graduate level students in mechanical engineering. The socio-demographic characteristics of students, those related to their educational background and their mastery of computer aided modeling tools are collected using a survey. To these elements are added the video recordings of the collaborative activity of six dyads involved in the design of improving solutions for an existing mechanical system. Wilcoxon and Kruskal-Wallis comparison tests, applied to the data, allow us to give a description of the studied situation. One notable feature of the sample studied is that learners who graduated from high school had higher spatial visualization scores compared to those who had a technician's certificate. The results show that learners with the weakest spatial abilities are more involved in solution drawing and in actions aimed at understanding the problem and solutions. On the other hand, the actions related to the evaluation of solutions and the ones inciting solution genesis are more the fact of learners with the highest spatial visualization scores. In the use of external representations on digital and stereoscopic media, the durations invested by learners with high spatial abilities are higher than those of learners whose spatial abilities are lower, although these latter use them earlier. However, there is no significant difference in the durations of non-spatial and paper-based external representations’ use.
