A comprehensive, user-interactive software package for the IBM PC or compatible, resulting from an ongoing effort by the author to enhance the teaching and learning processes in the instruction of introductory electromagnetics courses is described.1 The associated topics are distributed throughout the realm of introductory electromagnetics, ranging from coordinate systems to antenna fundamentals. The PC-assisted instruction involves the use of the software in the classroom integrated with the lecture-discussion of the subject matter, as well as outside the classroom by the student at his/her own pace and leisure. Following brief descriptions of the 15 programs of the software package, four examples are presented in detail to illustrate the teaching and learning nature of the software. Student responses to the PC-assisted instruction are included. © 1990 IEEE
