Combining multimedia and self-assessment CAD tools in an interactive web environment to learn engineering drawing

ABSTRACTInteractive Web Environments and multimedia tools are very common in engineering studies. However, these resources are very limited when graphical resolution is needed during the learning process. A learning environment that combines video and self-assessment Computer-Aided Design (CAD) tools was developed to analyse this problem and to determine if the combined use of these two tools may be important in learning these subjects. A comparative study of 124 engineering students was carried out. They were randomly assigned into three groups: Group-A using only traditional tools, Group-B using traditional tools and CAD tools, and Group-C using traditional tools, CAD tools, and video training. The statistical analysis of the results showed that a greater number of students of Group-C passed the test and improved their scores. Therefore, the combined use of these two types of resources can be an important aid in the study of subjects requiring graphic tools for their learning.
