What Types of Students Participate in End-of-Course Ratings?
With an increasing number of rating systems now online, the question of who completes those surveys (since not all students do) is one with important implications. Are those students dissatisfied with the course and the instruction they received more likely to fill out the online surveys? If so, that could bias the results downward. But if those students satisfied with the course are more likely to evaluate it, that could interject bias in the opposite direction.
