When delivering the unit’s content, instructors can use the pre-test results to gauge student understanding by asking questions related to areas where they had difficulty on the exam. Comparing the scores of both exams can be used to assess student performance following an instruction period. This allows instructors to identify any areas where further improvements are needed, or certain topics that require additional attention/focus before moving onto other concepts. This means that, when planning, delivering, and assessing an entire course, it’s important to examine pre-test results. They can help the instructor improve his or her pedagogical practice while helping their students understand concepts.
