This paper presents a computer-aided learning app based-on iOS platform, for the students trying to learn the woodworking skills. The app contains an interactive evaluation tool that can assess the learning effectiveness. Traditional woodworking usually involves many aspects of skills and knowledge, such as understanding the properties of materials, familiarization of operation of woodworking tools, innovative manufacturing, and production skills, etc. Basic university woodworking courses include theoretical courses and practical ones. After summarizing and analyzing these courses, we designed an interactive learning simulation system of basic woodworking, a system divided into three parts: concept learning, tool operation, and material processing. In this study, 12 freshmen and sophomores of university students participate in pre-test and post-test of the experiment of learning effectiveness and they also do a survey of System Usability Scale. The results show that the multimedia interactive system can effectively improve the effectiveness of learning woodworking concepts, and can stimulate students' interest in learning. This result is also reflected in the SUS scale.
