In POLS 100 (Politics and Government), students proposed a thesis and identified at least five sources before writing their term paper. My feedback on the proposal became part of the next task. Students revisited their thesis and sources as they developed the argument.
The next time I teach this assignment, I would ask for a short revision note. Which change did the writer make to the thesis or the evidence, and why? That would give me a way to see how the proposal feedback shaped the paper.
