The Instructional Improvement Questionnaire (IIQ) is a four-part questionnaire designed to collect evaluative feedback from students on their instructors and courses. The class characteristics section collects data from the student on variables such as grade point average, sex, class level, grade expected, time spent studying for the course, etc. The instructor evaluation section consists of 20 items that allow the student to rate various aspects of instructor performance. On each item the student rates his teacher on a five-point scale. The course evaluation section consists of 20 statements about various aspects of the course. Students respond to each statement on a five-point scale. The optional item section consists of 60 response positions that the instructor may use to record student responses to locally supplied items. Collected IIQ's are processed in two phases: answer sheets are optically scanned and responses are coded and written on magnetic tape; a program analyzes the data and produces a printed report of the results. There are four sections and an optional fifth in the computer report corresponding with each response section of the IIQ. A summary of research that has been conducted on the IIQ is then reported in three categories: faculty reactions to the IIQ, studies of reliability of results, and studies of the relationship between selected class characteristics variables and IIQ results. Sample computer reports are appended. (RC)
