IMO ethics and patience are two very important virtues that shlould be heavily be stressed to new bow hunters. Archery tackle has it's limitations and the hunter needs to understand this before ventureing into the woods. Unfortunately I don't think either ethics or patience can be taught. The best you can do is guide them in the right direction because once they are a field it's completely up to them.

I'm sure your course probably already hits on these but IMO they can't be stressed enough.
