Yes, I started to teach how to fix broken code in some classes: read and understand errors, where to look, etc. These are skills they really need but we let them figure them out by themselves. By teaching them how a code can be broken and how to fix it they figure out what is correct code.
It's much better this way than the other way around IMHO.
And yes they are scared to do mistakes, it's even worse in electronics classes!
