Improving Student Understanding of Coulomb’s Law and Gauss’s Law Available to Purchase

We discuss the development and evaluation of five research‐based tutorials on Coulomb’s law, superposition, symmetry and Gauss’s Law to help students in the calculus‐based introductory physics courses learn these concepts. We compare the performance of students on the pre‐/post‐tests given before and after the tutorials in three calculus‐based introductory physics courses. We also compare the performance of students who used the tutorials and those who did not use it on a multiple‐choice test which employs concepts covered in the tutorials.
