I don't know if it would help, but I used a scanner to listen in on ATC comms when I started my PPL(H) course. I was already used to operating radios, but was concerned that bad habits would creep in and I'd start using non-standard phrases when using airband. It really helped me and I've suggested a couple of friends do the same. To my knowledge, they all found it useful.
I realise that your request is for a different purpose, but it may well help if you're able to listen to several different "levels" of ATC. Not to record them, though, for obvious reasons.
