Confidence is key for effective peer feedback

Peer feedback is a powerful tool for helping chemistry students refine their scientific arguments, evaluate evidence and develop stronger reasoning. This type of formative assessment offers students the opportunity to improve a piece of work.

Yet in practice, many teachers find that peer review activities fall short of their potential. A research study offers a compelling explanation that the effectiveness of peer feedback depends less on the comments students receive and more on how they experience the task, particularly regarding the level of confidence they have in their own work.

The study shows that students with low confidence look for reassurance in peer comments and can feel destabilised by critique, even when it is constructive. Students with moderate confidence are more receptive. They actively search for specific suggestions that will help them improve. Highly confident students often treat peer review as a confirmation exercise. They skim for praise, discount criticism and rarely revise unless the feedback aligns with what they already believe.

These confidence-driven patterns interact with several structural barriers commonly seen in classrooms. Without explicit modelling, students often default to vague praise (‘looks good’) or blunt criticism (‘this is confusing’). Neither of which supports meaningful revision. Many also hold an expert bias, assuming that only the teacher can provide trustworthy feedback. When tasks have a single correct answer, there is little space for peers to offer substantive critique, making the activity feel artificial.

Peer feedback becomes genuinely productive when teachers design for collaboration, openness and metacognitive engagement. Reframing the activity is a powerful first step. When students understand that their role is to act as thinking partners rather than judges, they become more willing to explore alternative interpretations and to revise their own ideas.

Task design is equally important. Peer review works best in tasks where multiple defensible answers exist. Students have to justify choices, interpret data or evaluate competing explanations. These open‑ended structures create the cognitive space necessary for meaningful dialogue.

Scaffolding also plays a crucial role. Sentence starters and structured routines help students move beyond surface-level comments into reasoning-focused critique. A simple pattern, such as identifying one strength, one area for improvement and one concrete next step, gives students a manageable framework for offering useful feedback.

Feedback only becomes learning when students have time to act on it. Building in Dedicated Improvement and Reflection Time (DIRT) immediately after the exchange encourages students to revise while the feedback is fresh. Asking them to annotate their changes or justify why they chose not to use a suggestion deepens their evaluative judgement.

Low‑confidence learners benefit from exemplars, verbal rehearsal and reassurance that multiple answers are possible. Highly confident learners may need stretch prompts that require them to justify their decisions, especially when they choose to reject peer input.

Giving feedback is a powerful learning activity. Analysing someone else’s work helps students recognise strengths and weaknesses in their own reasoning.
