Problems with using real-time formative assessment
From Physiki
Using real-time formative assessment causes stress. Just think about going to a meeting. It is stressful if you have to "perform" in the meeting. Likewise it is stressful for students to have to think and solve problems rather than to just sit in class and take notes. It is particularly stressful if their answers are judged "right" or "wrong" and that judgement determines a grade.
We have found that giving a small amount of credit for an honest attempt at answering InkSurvey questions is enough to reduce stress while keeping them on task learning and not gaming the grade (texting answers etc).
