Because our PD was on the Middle School campus, I had students in 1st and 4th grade and faculty take videos of the Lower School campus from their own perspective and posted those to a website for people to look at. We used those along with a Pinterest page of creative learning spaces for the empathy portion of the design process. I also took people through a "Speed Dating" type interview process where they had a few minutes with a few different people to share what types of spaces they personally find inspirational.
We modified our "How might we" statements to focus more deeply on a particular question.
The day culminated in the making of prototypes. Faculty used a variety of materials to build their imagined spaces and then presented them to the faculty.
Overall, I think the PD day was a great success! I attribute that to a few things, a great facilitator (LOL), and a real problem to solve. Just as when we looked at Back to School Night, we are going to find ways to actually implement everyone's ideas. I think this is a key element for successful DT work. Otherwise it is just an exercise and doesn't have the same impact on the participants.
