The other thread dealt with a particularly narrow point of questioning, but IMHO a few simple general rules consistently and diligently applied by instructors would measurably improve students use of the radio when teaching the PPL. They are:
1) Make every student wait a few seconds before transmitting after a frequency change to avoid interfering with an existing conversation.
2) Before every flight take 2 minutes and practice a few calls with the student. That is pick a random part of the flight and play ATC. Be a hard case and make the student repeat the call until it is perfect.
3) Set the best possible example when you are talking on the radio. It is easy especially after a long day or when you are bored, to either take short cuts ( eg "upta 2.5 ABC", instead of "climbing two thousand five hundred ABC" or waste airtime with "witty" observations, irrelevant asides, slang etc etc. Particularly for ab initio, their only point of reference is you. If you set a bad example that is what the student will do, and the cycle continues
The above it is pretty motherhood, but it takes discipline on the part of the instructor to consistently apply it. Be that instructor.....
