‘It has been argued that for feedback to be effective, it needs to be provided quickly, close to the act of learning production. However, increasing student numbers, and additional demands on lecturers, makes this goal look unachievable. A radical solution may be needed to combat this: could Generative AI provide useful feedback to students at speed? This paper explains how a Generative AI tool was built to produce feedback to students on the MSc in Law and Professional Practice at King’s College London and examines the results of a study as to the advantages, and disadvantages, of using Generative AI to produce feedback. The results of the study have shown that while the students valued the speed of the feedback produced by Generative AI, and elements of its quality such as the specificity, structure and organisation of the feedback, ultimately they would view AI-generated feedback as a supplement, rather than a replacement, for lecturer feedback.’
