Process
How a warm or cold reputation fades over a semester
A three-step process showing what happened to student ratings of an instructor described in advance as warm or cold, measured before students met the instructor, after one lecture and at the end of the semester. It is for quality teams deciding when to ask students to rate teachers. The lesson is to avoid ratings based on thin contact. Koji lets a team-taught module ask about each teacher soon after their sessions.
What's in this process
- Before meeting the instructor: Students read a warm or cold description. The rating gaps were largest here.
- After a first 30-minute lecture: Most of the gaps had faded once students saw the instructor teach.
- At the end of the semester: All warm or cold gaps had practically disappeared.
