An Oregon (PCC) school adopted OER in Math. I have detailed handwritten notes (see me if interested). Their most important advice is to understand colleagues concerns.
Some things- look me campus-wide team building we are already doing.
Other things- generating buy in- we do not have to do as Michael Nealon and TB have bought in already.
They also say their notes will be in the proceedings. They are not there as of 11-10-2017.
