First may I say welcome to Whole Brain Teaching!
I was first introduced to WBT while attending a conference in Sacto this August. Though I have not yet had the opportunity to use the program with my special ed. SDC/LD students, I am excited to start using it on Sept. 8th, when classes begin here in Sacto. I would suggest that you watch all of the videos that are available, and give it a try. My classes are small, 15 in one group and 13 in the other, and I plan to use the program for both groups. The first week of school is dedicated to getting to know our students, and I'm excited to start the program with my students. I watched Chris Biffle use the program on all of the teachers at our training, it was beautiful.
I look forward to hearing what you found after trying the program, I know you will not be disappointed....and look forward to reading your posts soon.
