Normally, I come out of them inspired to implement a few new things in my classroom.
Normally, I have no problem filling out the reflection sheets and talking about, "What are you going to try to implement" or "What are a few of the things you learned in this workshop."
Sadly, I didn't feel like I learned much from the technology sessions that I took. Now, it could be because I try to use technology a lot already or it could be because I wasn't looking for the newest app or the latest site - I was looking for innovative ways that the technology was being used to transform learning and improve thinking...and that's what was lacking.
I did, however, have a much more positive experience taking an OTF session on teaching geography and how to help make my students people who might change the world. The focus was on critical thinking and relied a lot on materials published by the Critical Thinking Consortium https://tc2.ca/
If you don't already know of the work they do I strongly suggest you check them out. Also, find out if your board is a "partner", because some of the material is then available to you which you otherwise might have to purchase. Check it out (but make sure you have LOTS of time!) :-)
