I wanted to take the opportunity to recommend this site which I've been using quite a bit lately for my personal jazz study. I'm sure that it would be a great reference for any classroom teacher as well. His site is probably the most comprehensive free guitar lesson site I've seen. While most sites with this much information are a little dry, Justin's is a lot of fun and he's a great teacher. He has a real gift for thorougly presenting a topic while keeping it as simple as possible.
The material is sequenced and grouped in a logical way that defies the tendancies of most of us musical/creative types. There are beginner and intermediate methods on the site with text and video. You'll also find intermediate/advanced material covering various styles such as blues, reggae and jazz.
His presentation of the CAGED system with it's corresponding chords, scales and arpeggios is the best that you'll find on the web. If you're a teacher, the graphics for his chord grids and scales are a great reference.
All of this material is presented free. So, donate or buy something.
