We have studied whether repeated exposure to complicated physics concepts, such as quantum tunneling, fosters increased understanding. For three students, we have multiple interview, survey, and examination data over three years. We present data from a single student whose understanding of energy conservation in tunneling improved with repeated instruction, but whose ability to correctly sketch wave function solutions and discuss their meaning showed little progress.
