A method for modeling a tacit knowledge has been developed. Tacit knowledge is a type of knowledge that is difficult to describe with words or symbols such as sports techniques, design skills, etc. It is difficult for us to obtain and share this type of knowledge. In this paper, we discuss a new method to create a model of tacit knowledge by showing an example of web site designing. Usually, capable designers can express their intensions precisely through their works. This is to say, appearances of their works reflect their intention. Thus, it is expected that capable designers' tacit knowledge can be extracted from their works. Knowledge of the design was extracted from actual web pages on the Internet. Then, knowledge models were created by utilizing a Bayesian network. The created models were verified by LOOCV technique. The result shows that one of the created models illustrates part of a designers' knowledge accurately.

Authors conducted a workshop as an experiment to improve the engineering design ability and international sense of college students. Six Japanese students and 11 Thai students participated in the workshop. 17 students were divided into 4 teams and they proposed a new communication medium for each team. The students received several lectures and group work for the proposal. The students answered a questionnaire before and after participating in the workshop. As a result of analyzing the questionnaire, Japanese students realized that their ability was improved more than Thai students. In addition, students in other fields than engineering students said that their abilities improved.
