Many current Web-based learning environments facilitate the theoretical teaching of a subject but this may not be sufficient for those disciplines that require a significant use of graphic mechanisms to resolve problems. This research study looks at the use of an environment that can help students learn engineering drawing with Web-based CAD tools, including a self-correction component. A comparative study of 121 students was carried out. The students were divided into two experimental groups using Web-based interactive CAD tools and into two control groups using traditional learning tools. A statistical analysis of all the samples was carried out in order to study student behavior during the research and the effectiveness of these self-study tools in the learning process. The results showed that a greater number of students in the experimental groups passed the test and improved their test scores. Therefore, the use Web-based graphic interactive tools to learn engineering drawing can be considered a significant improvement in the teaching of this kind of academic discipline.
