Sarah, I too attended a 5 day Kagan Workshop summer 2008 and implemented the program and structures fully in my class this past year. After attending a WBT seminar and researching, reading, printing...I intend to implement only the WBT at first just to collect data and prove to myself that it is making a difference and then if so, continue and blend it with what I know works for me with Kagan. I am predicting that a blend of the 2 will make for an incredible teacher and excited high performing students.
I also am thankful to have learned one at at time. Learning and implementing both in the same year may have been a disaster. You know, not really good at either one. I suggest that a teacher only implement one way until mastered and then blend the two.
