I always try to make 'whole class critiques' an enjoyable period and not a
chore. We push the tables together (or chairs) so everyone is in closer
proximity. Occasionally we have a snack (juice or candy). This year I've
had successful critiques, where I try to do a minimal amount of talking.
I give the students a handout with sentence stems. Here are a few:
I'm pleased that.... I realize.... (Student name) could have...
I definitely thought.... The (element/principle) was used because.... Etc.
I usually have them first go once around completing a sentence stem I've
chosen. Of course, they can be written with different critique and grade
levels in mind. Critiques are actually becoming something the students and I
look forward to, instead of dreading!
