Query: Teaching assistants' performance at identifying common introductory
  student difficulties revealed by the conceptual survey of electricity and
  magnetism   We discuss research involving the Conceptual Survey of Electricity and
Magnetism (CSEM) to evaluate one aspect of the pedagogical content knowledge of
teaching assistants (TAs): the knowledge of introductory students' alternate
conceptions in electricity and magnetism as revealed by the CSEM. For each item
on the CSEM, the TAs were asked to (1) identify the most common incorrect
answer choice of introductory physics students and (2) predict the percentage
of introductory students who would answer the question correctly in a
post-test. Then, we used the CSEM post-test data from approximately 400
introductory physics students (provided in the original paper describing the
CSEM) to assess the extent to which the TAs were able to identify the alternate
conceptions of introductory students related to electricity and magnetism. In
addition, we conducted think-aloud interviews with TAs who had at least two
semester of teaching experience in recitations to explore their reasoning about
this task. We find that the TAs struggled to think about the difficulty of the
questions from introductory students' perspective and they often underestimated
the difficulty of the questions. Moreover, the TAs often expected certain
incorrect answer choices to be common among introductory students when in fact
those answer choices were not common.
