Higher education institutions rely on part-time faculty to teach a large percentage of courses in a range of disciplines. Existing research indicates that instruction by part-time faculty can negatively impact academic outcomes, student retention, and subsequent interest in a field of study. This study investigates if using a motivational information system can help close this performance gap. It introduces a type of motivational information system called an educational engagement information system (EEIS). EEISs draw on principles of behavioral economics, motivation theory, and learning cognition theory to help students want to improve their performance. The study compared student failure status in course sections taught by part- and full-time instructors both with and without an EEIS. Results suggest that using an EEIS can help improve student failure rates in courses taught by part-time faculty members and bring students' performance to parity with the performance of students taught by a full-time instructor. Features of an EEIS, such as the additional structure, grade and outcome trackers, and motivational elements, can augment a part-time instructor's approach and may compensate for limitations sometimes associated with part-time instruction including limitations of expertise, time, or rewards that can have a negative impact on students' academic outcomes. As a result, students can experience higher completion rates and better performance.
