This study is based on action research conducted with 117 students attending their introductory English language courses at two universities in Bangladesh. Peer feedback (PF), an essential part of collaborative learning, is an important alternative mode of assessment and can provide a deeper and clearer understanding of the learners’ aptitude and thus, aid the instructor in facilitating the learners. Not only can the learners benefit in terms of critical thinking while evaluating their peers, but also the peers can improve through the knowledge-sharing process. The objective of this study was to modify the notion of PF among the students as they were found to be producing vague, short, and shallow remarks on their peers’ writing. The study uses the PF comments on peers’ writing collected during the observation stage of an action research project to identify the weaknesses in the participants’ feedback to their peers. Then, it documents the process during which the causes of the weak PF are discovered and addressed, and learners are made more aware of the importance and benefits of PF. Finally, it examines the outcomes of a second round of PF, illustrating the improvement in the quality of the PF and the increased satisfaction of providers and recipients of the PF.
