A critique strategy I like to use once students have the basic idea of the process down, is to form them into small groups to evaluate each others’ work. I’ll either form them, or allow them to self-form into groups of three, and give them time to round-robin their work. For guidance, I might write questions they should address on the board. I’ll also instruct that each of them will be responsible for presenting one of their peer’s work to the greater class.
This can be a nice technique for helping them to converse more deeply about an individual project, to help them develop their presentation skills and to allow the quiet student to feel more comfortable expressing themselves in a smaller group.
