A group of three students sit around a table, working on laptops. A quote is overlaid: "Is there a way to conduct peer assessment that is valid and perceived as fair?"

I’ve got it! What if they grade each other?

In previous posts, I’ve discussed how collaborative assignments pose a challenge for valid assessment because the resulting product typically reflects pooled ability and effort (for a good review, see Webb et al. 1998). One way instructors have attempted to overcome…

Do Cohesive Groups Matter?

In previous posts (here and here), I’ve been writing about the different ways that groups can be created for class projects, and whether the method of group assignment has an impact on learning. In this post, I want to focus on one…

Are Group Assignments a Waste of Time?

Are group assignments effective pedagogy or a waste of time? This is the question asked by researcher Michael Thom (2020) in his recent paper examining the scholarship on collaborative pedagogy. To be clear, I’m being literal here. The title of…
