University of Pittsburg Research-based Electrostatics Tutorials
The following materials cover Coulomb's Law, Gauss's Law, the superposition principle, and symmetry and were developed by Chandralekha Singh and the University of Pittsburgh PER Group. The materials are appropriate for a calculus-based introductory physics course.
The tutorials are designed for use after traditional instruction as in-class supplements, out-of-class homework, or student self-study tools. The authors recommend the tutorials be given in-class to students working in groups of 2-3. A majority of groups can finish a pre-test and tutorial in a 1 hour 50 minute period.
Optional pre- and post-tests are available. If used, pre-tests should be given after traditional instruction and before the tutorial. Post-tests should be given the following class so those who do not finish may do so at home. Each test requires 15-20 minutes to complete. Professors may give a pre-test in-class after traditional instruction, a tutorial as homework, and the post-test the following class.
