As Sallie was Googling at the Summit at WLC, I was presenting at a one to one conference down the road at CUW. We explored the philosophy in connection to the possiblities offered by chromebooks, tablets, etc. In my research, Dave Tess and Jason Schmidt came through with some information on the latest chromebooks and their inability to project easily through VGA projectors. This is another reason that chrombooks can't be considered a teacher's main device, IMHO. Also, this information impacts purchasing of classroom projectors for the future.
Take a look at PicKATime for conference scheduling. Ours is up right now so you could look at it on our site - emanuelnl.org/school
Works great and parents love it; not free through. $50 a conference. We think it is worth it. The secretary sets it all up and teachers have access and see their own scheduled conference times.
I find youcanbook me works well for teachers setting up individual conference tmes with me for purposes of their tech growth planning throughout the year.
