Differentiation

Recently I did a short gig making suggestions for some lesson plans that will be published online.  One of the items I had to assess was the differentiation presented in the plans.  While the ideas were great and varied, there was no differentiation presented.  Likewise my school had a presenter do an in-service on the very subject and he too just gave us a bunch of different (great) ideas on ways to teach, but did not explain differentiation.  As I see it differentiation is having different ways to teach the same lesson, but bases it on the needs of the individual user.  To help my department out, I put this in-service together on differentiation so that we can do a better job with it.
