An evaluation model was developed to aid the classroom instructor in more effectively teaching his course by providing him with the basic data upon which to make judgements about student abilities, course attitudes, grade distributions, test appropriateness, etc. The MERMAC system was designed so that each instructor could obtain the data in a usable format and also be able to provide relatively immediate feedback to the students taking an examination or filling out a course evaluation questionnaire. A description of the software system and its interface to the evaluation model is presented. (Author)
