Leading PBIS Professional Development

This coming Tuesday, we are having a professional development day in our county.  My principal (I'm at a high school)  has asked me to lead an hour long session on PBIS.  We have kicked off PBIS this year, and so far, it has gone smoothly.  We have good buy in from the faculty and students as well.  The initiatives we have concentrated on, tardies to class and cell phone abuse, have really improved.  So, I am a little concerned about losing some of this positive energy by making the faculty sit through an hour long training. We all know how teachers hate meetings!  In order to combat this, I sent out a survey last week asking the faculty what additiional information about PBIS they would want to know.  I received some good feedback from this so I plan on addressing those questions.  I also plan on doing a data analysis on the referral data.  I will show our top behavioral concerns and show the improvement we have made.  Finally, I plan on leading a discussion on an area where our data shows we have regressed from last year - classroom disruption.  My feeling is that classroom disruption referrals are up from last year because students can no longer get lost into their cell phone.  I plan on talking about strategies and best practices to increase student engagement in the classroom and to talk about how building relationships with students will lead to less classroom disruptions. Hopefully this will be an engaging hour and we won't lose any of the momentum we have built up.  Can you think of anything I am missing or anything else I should discuss?
