The current study seeks to analyze university students' perceptions of online peer assessment (PA) with regard its effectiveness as a learning tool and as a contributing factor to motivation and interaction. Participants also responded to questions about self-perceived writing strength, attitudes toward peer review, and experiences with peer review. The survey was administered via link online for students who report having completed peer review in online courses. Results from participants revealed that students generally believe peer review to be effective, helpful to learning, increasing communication skills, and as contributing to a stronger written end product. Students also agreed that peer review increases interaction, participation, and a sense of community. Attitudes toward peer review indicate that female students are more intimidated by giving peer reviews than their male classmates, but they felt less intimidated online as compared to face-to-face. More experienced students and students farther along in their college careers are less likely to give peer reviews that are affected by the ones they receive. The results indicate that peer review is an important teaching and learning tool that merits more research with particular attention to gender and other demographic data.
