John,
An external reviewer (peer review) is an excellent topic to bring up. It is always nice to have "fresh eyes" when you are developing a course. Others can see if it seems logical and organized when you can't because you are "too close" to the course. I hope that makes sense.
Also, ask students questions as you are teaching the course. Can you find what you need? Stop - Start - Continue --> What do you want me to stopd doing? What do you want me to start doing? What do you want me to continue to do. This formative feedback is exceptionally helpful.
Thanks again.
