Knowledge survey questions with a confidence scale
A sample knowledge survey for an introductory statistics course, with nine items grouped under three course outcomes and a three-point confidence scale adapted from Nuhfer and Knipp. It is for lecturers and assessment leads who want item-level evidence of where students feel ready, to set beside exam results and course evaluations. Give it at the start and end of the course and compare. Koji can ask the follow-up about why a student feels unsure.
