Abstract
Information system developers often encounter the problem that clients do not understand the significances. Therefore, it is difficult to analyze “the demand”. Project Based Learning(PBL) has the same problem as well. To solve it, we thought go back to the basis of fundamental informatics. Moreover, we introduced an idea, “it is a human being who adds the value to the information, and if we produce a loop of languages which changes his/her behavior, a new value generates”, into PBL. In this PBL, we take the dental practitioner who is in the serious business situation as a model case. Firstly, we suggested the loop connecting the doctor, the client, with his patients, the end-users, with “the patient's card” as the information system (the first phase). Through it, he realized that using the information system increases the number of patients who revisit. Secondly, we proposed and constructed the website, another information system, which puts him in the loop of information (the second phase). It has his social contribution activities and a link with his SNS. As a result, it was the client who changed the most significantly. He voluntary engaged in encouragement of the prospective and present patients to come to his hospital as a sender of the information. People frequently point out the importance on the ability of “suggesting the information system”. We realized it is effective to produce “a trick” to encourage a client to change his/her behavior related to the information on construction of information system through this PBL.
