This review article summarizes 37 empirical studies on assessment feedback provided to undergraduate students for written work across various disciplines. The studies explored: (1) students' perspectives on the effectiveness and utility of feedback, finding mixed opinions on what constitutes effective feedback; (2) teachers' divergent styles of providing feedback and lack of guidance on learning improvement; and (3) divergences between teachers' beliefs and practices regarding assessment criteria and the dual roles of feedback. Overall, the studies point to issues with achieving the dual goals of formative and summative feedback through current assessment practices.
