Conceptual design of question-answer processing method for operator educational system

It is necessary to develop an interface with easy communication for the practical use of an operator educational system. This paper describes the concept of the 'answer output processing method' which makes the communication easy using the characteristics of the operator educational system. The main features of the method are as follows: (1) The prototype of the operator educational system is provided with educational materials which are expressed in terms of cause and effect relationships of events. Answer generating functions are introduced to infer the relationships easily during the question-answer process. (2) It is easy to provide the materials of the educational unit optimally adapted to the degree of achievement which is already included in the prototype and is also easy to change the level of the materials based on the questionary history which is newly introduced for recording the question-answer performed everywhere in the learning process.
