Engineering graphics is an essential tool for industrial designers. There are many factors that would affect the performance in engineering graphics; spatial ability is probably one of them, and working memory is another. Many studies have found that spatial ability can effectively predict complex performance. In this study, working memory was based on spatial working memory as well as spatial short-term memory. Therefore, structural equation modeling was used to investigate which factors affect engineering graphics. In the experiment, each variable is made up of three tasks and totally each participant conducted twelve tasks. According to the structural model, spatial ability directly affected performance in engineering graphics, but spatial working memory and spatial short-term memory did not. Thus, from the results of this study, spatial ability is a major factor affecting performance in engineering graphics. |
