Peer review is an active learning technique in which students evaluate peer assignment submissions and provide each other feedback. There are several benefits to using peer review in a course, including increased attention to detail and quality and engagement in constructive critique (Chong, Goff & Dej, 2012). Peer review may also help students develop effective problem-solving strategies (Wagner & Rutherford, 2019). Peer reviews can impart cognitive benefits for both students who conduct reviews and students who receive peer feedback (Knight & Steinbach, 2011). When implemented effectively, the peer review process equips students with valuable feedback and promotes classroom community.

While student populations have become increasingly diverse, many groups, including first-generation, non-native English speakers, and individuals with disabilities, still face barriers and bias that can derail their success in college (Super et al., 2020). Traditional grading practices—including penalties for late work, writing in dialects other than standard English, and even plagiarism— are prone to bias and only perpetuate disparities, the research says (Feldman, 2019; Savini, 2021).

Problem Based Learning is a teaching method used to facilitate student knowledge acquisition. This teaching method is often confused with Project Based Learning, which centers on students applying knowledge. The focus of Problem Based Learning is students acquiring the knowledge. Since the two methods use the same acronym, they are easily confused, but have different objectives for students.
