Nice thread idea! Although I do think we're too tired/busy/run ragged 95% of the time to even consider whether this is a 'positive' experience! Generally my PGCE experience has just been one of 'trying to survive the day'.
Aaanyway, that said...I am feeling (gasp) a bit happier today. I think because I came up with a good lesson idea, planned it to the smallest detail, delivered it well, got a BOTTOM SET to do a good hour's worth of quality work...and got them to (genuinely) enjoy it (believe me, they let you know when they don't). Check me out!
Pretty sure I'll be back to run ragged by next week, but we've all got to remember to enjoy our triumphs. Chin up folks!
