Three introductory electromagnetism conference sections were given groupwork, applets, or nothing in class before each exam, and the resulting exam grades were compared. To correct for differences between tests and between sections, each section was given groupwork, applets, and control in different orders. Each group performed within 3 points of the control, within the statistical margin of error. A different set of students was given applets and groupwork the next term and interviewed about the experience.
