Improving Students' Understanding of Coulomb's Law and Gauss's Law
  Location: HC 3023 & 3023A
  Date: Tuesday, Aug.2
  Time: 1:55 PM -2:05 PM
  Author: Jing Li, University of Pittsburgh
  Co-Author(s): Chandralekha Singh
  Abstract: We discuss the development and evaluation of five research-based tutorials on Coulomb's law, Gauss’s law, and the superposition principle to help students in the calculus-based introductory physics courses learn these concepts. The tutorials were developed based upon research on students' difficulties on relevant topics. We discuss the performance of students on the pre-/post-tests given before and after the tutorials, respectively, in four calculus-based introductory physics courses. We also compare the performance of students who used the tutorials with those who did not use them. We find that students performed significantly better in classes in which tutorials were used than in the classes where students learned the material via traditional lecture only. We also found that the students who worked on the tutorials and performed differently in the pre-test all have improvement in the post-test.
