The teaching assistants (TAs) who lead each tutorial section are important arbiters of these norms. TAs who value (buy into) tutorials are more likely to convey their respect for the material a...

We measured student performance on a research-based conceptual instrument -- the Brief Electricity & Magnetism Assessment... S. J.

First, we misidentified the distance metric used in that paper. More importantly, the distance metric that we used was inappropriate to the coding scheme we developed for our data. Finally, we were not rigorous in how we defined the groups we identifi... R.Padraic Springuel, Michael C. Wittmann and John R.
