In this study, we developed a system based on a problem-solving process model of the Japanese Patent Act to support knowledge acquisition among engineering students, who are better at interpreting the use of logical formulas and logic circuits than they are at reading legal texts. The knowledge acquisition support system helped students construct legal articles by themselves by using logical formulas and logic circuits. We found that this system was rated favorably by some students and that it was useful for their knowledge acquisition. Meanwhile, it is necessary to improve the system for those students who did not rate it favorably and to devise a support system for term exams. We speculate that such improvements will increase usage of the system, which in turn will lead to further support for knowledge acquisition.
