Instructions

A sample of a Learning Module is presented here. The general topic of DC circuits is addresssed, with a specific focus on particular misconceptions relating to current and voltage. The choice of concepts (or misconceptions) to cover in this example has been guided by research in Physics Education, in this case based primarily on Ref. 13. The problems can be viewed here without actually logging into a LON-CAPA course. Click on the link in the lefthand column of the table. Answers can be entered and evaluated. You can also click on the button provided to see a new problem variation. Each student will receive their own variation on the problem.
