This paper lists 15 commonly held misconceptions concerning quantum mechanics, such as "Energy eigenstates are the only allowed states" and "The wave function is dimensionless." A few suggestions are offered to help combat these misconceptions in teaching.

We investigated student difficulties in learning quantum mechanics in an upper division quantum course at the University of Maryland. A set of exam questions and interviews has been developed to probe student understandings of the quantum wavefunction. We find that many students are confused about the relation between the wavefunction and the kinetic energy and often appear to interpret the wave function as an energy. They often display a strong "friction-like" model in which the wave function "loses energy" in tunneling through a barrier.
