"Well Bloggs, how did you feel about that
I know that's an often used line ..but I possibly went to the same big teachers school as Beags and so like him lines like that, and also the dreaded " How do you think it went" were a "no no" - and I still hate it when it's an opening gambit these days when I've been under check. I think it's really unfair on the student to ask him/her to assess their own performance from the "get go" but then again I've always been a softy
Personally it's a long time since I checked anyone but once upon a time my debrief template was:
1. Start by getting the pass/fail bit out of the way (and boy I used to really hate the fails) ...
2. Tell them what you really didn't like ,
3. Discuss any points of interest/grey areas,
4. Tell them what you did like....because even in the most dire fail there's was always something the student can take away as a "well done",
Always end on a positive point for the stude (and then you can chop him/her anyway
).
