I created these for my intermediate students and they really bought into it. I started off writing them myself, but as time passed we took the time to learn how to write sincere, detailed praise and thanks and it took off from there. Looks great on coloured paper and taped to the entrance of the classroom door. At the end of the year, pile up each student's 'shout-outs' and present them. I have pinned a couple other templates - for variety on the wall.
Interesting idea!! A secret student is randomly selected and the teacher monitors that student for the day. If the student does well, he/she is recognized and is rewarded. If he/she does not do well, the student is not named and the teacher just tells the class that the secret student did not have a good day but tomorrow will be a better day.
