N.D. Finkelstein, W.K. Adams, C.J. Keller, P.B. Kohl, K.K. Perkins, N.S Podolefsky, and S. Reid, "When learning about the real world is better done virtually: A study of substituting computer simulati
This paper compares teaching circuits using a a virtual lab and using a real lab.
Prompts: 1. Has this paper persuaded you to use the PhET or similar simulation when you teach circuits? Why or why not? (Note: If you do not teach circuits, consider what you would do if you did teach circuits.)
2. In general, what are the strengths and weaknesses of virtual labs? What are the strengths and weaknesses of hands-on labs?
