How Dev Bootcamp Teaches: ActiveRecord

I'm Jesse, one of the co-founders of Dev Bootcamp, and the acting curricular editor-in-chief. We get lots of questions about how Dev Bootcamp approaches teaching, what our curriculum is like, and how it differs from other schools and competitors. I thought I'd share some of that with you, starting with a brief overview of our theory of learning and then sharing our introduction to ActiveRecord.

This will be light on theory and heavy on ActiveRecord, so if you're not familiar with SQL or Ruby it might be hard to follow. Mea culpa.
