Consideration of the design methodology of digital teaching materials for practical training classes on casting and forging

Experimental subjects in science and engineering courses at universities and other higher education institutions are one of the most important subjects for acquiring knowledge and skills. However, due to the lack of skills among young people these days, an increasing number of students are not interested in experimental subjects because they cannot perform the experiments well. This paper proposes design guidelines for digital teaching materials for practical training in manipulating tools using the body such that casting and forging. In this practical training, motivation of the students and awareness of learning may be reduced, when low skill levels worsen work costs and product quality. And it is assumed that students who will use the digital materials are beginners and are not familiar with the tools used in practical training. Under these conditions, this paper discusses the specifications for the design of digital teaching materials that can achieve the contents of each stage and proposes a method for realizing these specifications. The proposed method introduces spatial perception and 3D models of tools, taking into account not only the student’s knowledge and skills, but also the mentality of beginners. The effectiveness of the developed digital teaching materials will be examined through interviews with students.
