Digging Deeper in Understanding

So I have begun working on my pre-calculus lesson plans for 2012-2013.  On Flipping with Mrs. Kirch, she talked about TWIRLS - thinking, writing, interacting, reading, listening, and speaking which she got from SIOP training.  I have never heard of SIOP but it stands for Sheltered Instruction Observation Protocol found at http://www.siopinstitute.net/index.html

Could be an interesting professional development institute to attend although most of my students are not English Language learners but focused instruction on TWIRLS make so much sense for classroom expectations.
