No offense, but "assignment and syllabus design" scratches the surface at best. And while I understand the desire to let students experiment with teaching, it's worth keeping in mind it's an experiment on other human beings. (So, technically, subject to IRB review.) Again, this isn't your fault. This is a massive failure of the education system in general. We pretend that as long as somebody knows the subject, they're decent teachers. (We pretend that because it's cheaper, and we pretend it because otherwise established faculty would have to admit that a large number of their members are extremely bad teachers)
