- 2. What makes a good peer instruction question? sgts.ucsd.edu 2 clarity Students waste no effort trying to figure out what’s being asked. context Is this topic currently being covered in class? learning outcome Does the question make students do the right things to demonstrate they grasp the concept? distractors What do the “wrong” answers tell you about students’ thinking? difficulty Is the question too easy? too hard? stimulates thoughtful discussion Will the question engage the students and spark thoughtful discussions? Are there openings for you to continue the discussion? (Adapted from Stephanie Chasteen, CU Boulder)
