A study of effective application of CG multimedia contents for help of understandings of the working principles of the internal combustion engine (the learning effects of the animation and the e-learning contents for explanation of working principles)

In order to help the understandings of the working principles of an internal combustion engine, the multi-media contents were developed and used for the lesson of the machining practice exercise. Moreover, the learning effect of the contents was examined with the aid of the drills and questionnaires. As the result of the examinations, it follows that the rate of the right answer of the drills was about 60% with the use of the drawings of the principle of an engine working, and that its rate of the drills turned to about 80% after e-learning training. In the case of the Diesel engine lesson, the learning effect was appeared remarkably in comparison with the Otto cycle engine.
