A study was conducted at Lakeshore Technical College (LTC) to assess the relationship between students' overall ratings of their instructors and their ratings of particular aspects of their courses. The study sample included 262 first-year students enrolled in at least one general education course and one occupational course in fall 1986. Students were asked to evaluate the course in terms of its difficulty, out-of-class preparation requirements, the grade they expected to receive, usefulness of course information, its planning and organization, presentation of subject matter, assignments, exams, textbooks, instructional materials, and bias. In addition, students were asked to evaluate the instructor in terms of knowledge of subject matter, clarity, enthusiasm, use of class time, encouragement of student participation, feedback, and interaction with students. Study findings included the following: (1) significant differences in students' overall ratings of instructors were found between male and female students; (2) student ratings of instructor knowledge of subject seemed to be independent of other items; and (3) 5 of 29 items were significantly related to overall instructor evaluation (i.e., "instructor spoke in a way that helped me learn"; "course was well planned and organized"; "instructor encouraged thinking, problem solving, and decision making"; "instructor explained materials clearly"; and "instructor demonstrated interest in my learning"). Based on study findings, recommendations for modifying instructor evaluations were developed. The report includes 117 references and the instructor evaluation form. (AAZC)
