We have developed a computer assisted instruction (CAI) system for simulating 3-dimensional mechanism construction. In this study, the system was applied to out-of-class learning of gear mechanisms. Fundamental questions and exercises on gear mechanism construction were delivered to students who take the class in machine mechanism design as the contents of the Leaning Management System (LMS). Since few students dropped out in exercises of mechanism construction, the system seems to be useful for out-of-class learning. And, the analysis of the access logs obtained from the LMS reveals that there are four typical learning styles among the students. The analysis of the logs also suggests that the system with simple user interface to construct mechanism is recommended to some students. Additionally, answers to the questionnaire indicate that the system is effective for students to improve motivation for studying and understanding of gear mechanism.
