Dance Coach is a collection of Quicktime Videos of ballroom dance patterns. You can use them to learn how to dance, but keep in mind that they are not intended to be perfect representations of the patterns. Thus, you can learn how to dance by learning how to critique dance.
A curriculum will eventually be built up around this collection, but in the meantime, send in an email with comments and suggestions.
I publish articles which connect Learning Theory and Ballroom Dance in Dancing USA Magazine. This publication is well worth the subscription price. It contains reviews of where to dance, interviews with dancers, and much more.
