The other thing I wondered about is the different expectations. If your instructor still thinks myspace is where the cool kids hangout....
Well having grown up in the UK and been to computer lessons in school (in the 1980s) I'd say that my expectations were that the teachers knew the subject material. When it came to maths, physics, chemistry etc. the teachers I had really knew their stuff and I learnt a heck of a lot from them but with computing it was far more variable.
I almost got into real trouble in one class using BBC Micros. We were told to write a program to add two numbers together which was incredibly trivial so, having the same computer at home, I thought I'd do the assignment in a more challenging way and teach myself assembly to add the numbers using the 'Advanced User Guide' which they had at school but I'd not got at home. I ran into some problems (you had to loop the assembly code through the parser twice to compile it) and when I asked for help and she saw the code she threw a fit. I was threatened with detention for not doing the assignment etc. etc. despite my protestations and explanation.
Fortunately the senior computing teacher walked in before anything got set in stone and she got him to come over to show him how badly I'd been behaving. His response was 'leave him to me' at which point he sat down and proceeded to show me what I was missing and then set me the challenge to figure out how to add two numbers which gave an answer greater than 255 (since it was an 8-bit machine) and how to store negative numbers using 2's complement. I learnt more computing in the 10 minutes he spent with me during one of his free periods than I learnt in the entire rest of the term with the idiot we had who was supposed to be teaching us.
So this is hardly a new problem. Teachers have a duty to make sure that the know what they are teaching and, worse, if their reaction to someone who may know more than they do is anger and hostility then they really have no business at all being a teacher at all. Who cares what they think about "fashion" - that's only relevant to education when it comes to engagement and sometimes being hopelessly out of date can be more engaging than being up to date.
