This was her first time teaching a class by herself. She struggled to build enough confidence to take command of the room. She would ask, "Does anybody want to comment on this painting?" rather than, "How does this painting illustrate concept x?" Very few students took up her offer.
She also struggled to organize the lectures, homework and exams. The requirements for the exams changed several times as students repeatedly stated that existing requirements were too ambiguous or broad to study for.
She seemed to have shored herself up by the end of the semester, but she's still very green. Get her while she's malleable.
