ocTEL BIG and little questions

I enrolled on ocTEL last year but found it very difficult to keep up. Here starteth attempt number 2!

I have two BIG questions ...

1. How to inspire colleagues to take up optional training and enahnce their teaching with technology. nothing is as big as that in my context
2. How to measure impact when we do change treaching. We are asked all the time by accrediting bodies, managers ... I would like to learn how others do this and be able to respond better to requests in future
