Artificial intelligence is full of potential and has been trumpeted as our saviour, the way forward, the answer to all the world鈥檚 ills and the future of learning. But this is not the true picture. Yes, AI has much to offer in education, but it鈥檚 not the be all and end all.

Tremendous advances have been made in the field thanks to new algorithms, availability of massive datasets and huge computing power at low cost. True, the time saved by lecturers on marking assignments could be used to enrich teaching, but unfortunately many silver linings have a cloud.

One downside is that lecturers will not get to know their students as thoroughly as is desirable if they never do any marking. Some middle ground is needed 鈥� AI could mark some assignments, but for a lecturer to accurately assess and understand a student鈥檚 ability, it is vital that the lecturer sees a significant amount of a student鈥檚 output.

When the Institute for Ethical AI in Education (IEAIED) set up focus groups to consider students鈥� views on the use of AI, several students were indeed concerned that lecturers wouldn鈥檛 get to know them as well as needed to if their work was being marked by AI algorithms. The IEAIED has drawn up guidelines for universities and schools to consider when introducing AI, so ethical issues do not offset the benefits.

Another concern that arose in focus groups was how to cater for students who are struggling with the course. While it is great news that the most able can benefit from a system whereby students learn at their own pace using a personalised AI programme, does that mean that those who struggle get the lion鈥檚 share of a lecturer鈥檚 time? What is the downside of this, if any? It can鈥檛 simply be the case that lecturers鈥� teaching time is axed because the AI is doing their work. Those who struggle will still need plenty of explanation and interaction from a lecturer, but others also need to be intellectually challenged to achieve their full potential.

At the University of Buckingham, we are already looking at ways of using AI to predict student outcomes. The aim is to identify at-risk or borderline students for early intervention. We used past students鈥� performance data, such as assignment marks and exam marks at each stage of their study, to train machine-learning models to predict the students鈥� final degree outcome.

At first sight, the capacity of AI to predict a student鈥檚 final grades from the first set of exams seems like a panacea. But considering the practicalities throws up all sorts of difficult questions: if AI predicts a student will fail or drop out, how should that be handled? Will a university鈥檚 action be driven by the need to put bums on seats, or will it act in the best interest of the student? Would seeing such early predictions motivate students to do better or demotivate them to think higher education is not for them? And what about students who are not deemed at risk or borderline 鈭� will they get no attention?

AI can certainly harvest a plethora of data on all aspects of students鈥� lives, but this raises another issue. Gaining information about how a student studies and the number of times they visit the library might help AI algorithms predict their performance, but surely the learner is entitled to know which data are being measured and how they are used.

Attending lectures, tutorials and spending time in the library are not the only learning activities. Students use YouTube as well as online resources and communities to learn. How would AI account for these data points?

Another less-discussed aspect is data ownership and who can profit from that data. Unlike the free services offered by internet search providers and social media platforms to whom we give our data for free for them to profit from, education costs students. So, should they be entitled to a payment from universities and edtech companies that profit from using their data?

The fundamental question, though, is whether it is right to use past students鈥� data to predict the performance of new students. We are all far too familiar with last year鈥檚 A-level fiasco.

Clearly, AI can be a force for good in higher education. It can be the answer to many a lecturer鈥檚 prayers in terms of reducing onerous tasks. But it cannot be introduced at any cost. All sides must be considered before AI is brought in, so that the benefits in learning it can bring are not cancelled out by the ethical problems its use entails.
