Samples of Rubrics and Checklists for Assessment
Here is Sheila Toth's oral presentation rubric. I think it is clear and simple so that students can also use it to assess their peers. This collaboration rubric may be very useful to assess the projectwork process: at the beginning: how far students are participating, sharing responsabilities; and while they are working on their projects: having conversations, reviewing each other's work, etc. Finally, this is a sample of power point presentation assessment sheet that you may find useful too.
