In my case, at the very least, I had a fair amount of support.

First of all, I explicitly signed up to teach. At my university, fewer than ten undergraduates per semester teach a class, and typically it's for students who want to hang out and teach something they like. In order to teach, they have to take an introductory class on pedagogy first, which mostly covers assignment and syllabus design.

The student-taught-course program at my university exists far more for the (undergraduate) instructors' benefit than to teach students; its job is to give students a chance to experiment with teaching early on.

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)
