Practicing is a huge factor in preparation which can help ease any doubts that we might have. This probably explains why (as Brian mentions in his post) many of the doubts arise as students are preparing for their final semester and student teaching. Another great way to get experience with a more realistic group is to contact public school teachers around your college/university and ask if you can come in to observe. Chances are, as you observe more, you may have the opportunity to get some hands-on teaching experiences (sectionals, small groups, individually).

Teachers have it tough – there is a huge responsibility. I haven't been in a classroom yet so I don't know how my classroom management skills will go – that would be one of my doubts that I am working on.

In one subject we have gone through possible scenarios that might occur – from the silly to the serious – and how to manage them.

I'm pretty sure your questions were rhetorical – but I am interested to know what other people are thinking on this matter. Especially those that have been teaching music for many years
