before, during, and after class to attempt to make mass instruction a meaningful educational experience. In order for a student to be certified as an educated layman, many schools require that he achieve a minimum grade point average in a broad range of courses, that he demonstrate competence in a particular field of study, that he be educated in computer or foreign languages, and that he swim one hundred yards or drown trying. Such requirements, for better or worse, mean that many stu dents will be enrolled in lecture-discussion courses as un derclassmen. This being the case, the classroom format typical of these courses must be closely examined. The modest revisions to the lecture-discussion method of fered here provide a reasonable means of educating large classes without the high cost and major revisions usually necessary in the use of educational technology (1). It should be quite plain, however, that there are no easy routes to improving the service course, nor are there any panaceas for the problems associated with it. It is hoped that this brief essay will stimulate changes in existing methods of instruction and encourage the exploration of new ways to teach required courses.
