Excellent presentation of lessons, well written assignment instructions, excellent response of grading tutor. My only suggestion is that you add a video (at least one) for the Teaching Large Classes course. After watching instructors teach very high level students in small class settings, it was extremely difficult to extrapolate this information to create a viable lesson for a large class. Regardless of the amount of instruction on how to organize for teaching in this environment (which was plentiful!), an actual presentation would have made all the difference... especially to a visual learner such as myself or someone who has never set foot in a classroom, let alone been charged with presenting information to 60 teenagers(!) Please help future students by providing a video for this course.
