| Research Abstract |
Subjects studied in this research are as follows. (1) Reconsideration and rearrangement of materials to teach in Electromagnetics of university level. (2) Suitable teaching methods depending on different student's ability and individuality. (3) Frame work of ICAI system on learning of "Electromagnetics Exercises. (4) Professor's knowledge base described by a production rule. (5) Student model by which student's learning process can be evaluated. (6) Infitence mechanism through which student's errors in his/her answer can be found. (7) Classification of problems by key to solution, and answer index system.
Electromagnetics in university is taught from Static electricity to Maxwell equations, using the vector analysis. However, the lecture, which is given in the form of mixture of electromagnetic phenomena and the vector calculations, is not suitable to students who are weak in mathematics. Also, some students are interested in the practical applications of electromagnetics, rather than m

athematical treatments. We propose to classify students into 3 courses, that is, math, usual and application courses, according to their interest and ability, and to teach different materials in respective course. We construct the ICAI system, which is constituted by an eletromagnetic mode and a guidance mode. In the electromagnetic mode, a problem is produced by a computer, referring a student model which represents an index of each student's understanding level. If a student's answer is not correct, the mode transfers from the electromagnetic to the guidance mode. In the guidance,mode, a few easier problems are presented with any suggestions. Data on the solving process is recorded in the student model. Professor's Knowledge base is written by production rules. Learning systems on exercises of "Vector analysis, "Static electricity and "Electric circuit are prepared for the above mentioned 3 courses, respectively.
Besides the above study, an answer index system is constructed. If a student, who has an unsolvable problem, can answer a few questions presented by the computer, the computer suggests him/ her a key of solution of this problem. Less
