 So I'm here now with Bird Violin, who gave a great keynote speech today at the opening ceremony of the Eden Conference in Bruges. And Bert, I heard you mention quite specifically that exams are a good thing. Now, often people would say maybe they're not a good thing. What do you say about that? Yeah, I was afraid that I was a bit too optimistic on that. But it's true. I mean, research shows that exams are really beneficial. You really learn from doing exams. So I thought I had to make a point about that and try and convince people about the usefulness of those exams. Well, both the teachers and the students are the learners because they are both concerned when it's about making exams more sexy, more popular, more useful. And that's what I wanted to talk about here. So you mentioned teachers working and learning with students. Is that important, do you think? I'm convinced they should. I mean, going back again to the technology side of the things, I think teachers and learners should really meet each other in analysing the results of those platforms and things. I mean, we talk about big data and there are lots of data available on when and how and where and so on. But I'm sure the key to analysing that in a good way is when teachers and learners get together and do that together, really. Yeah, that's something where I think teachers can learn from learners and learners can learn from teachers very much. So you mentioned big data, which I would call learning analytics. I think we're agreed on that. What are the limits of learning analytics? There must be a few. I think the limit is in our imagination. I just had an interesting discussion a few minutes ago with someone about it, but the idea is probably not the technology and the algorithms. It's finding good use cases where AI and big data can be of a real use for us. And I think that's the biggest challenge, finding very specific questions where big data and AI can find solutions for. So probably the problem is not with the data and not with the technology. It's with our imagination and how we can make sure that the things that we develop are really, really helpful. I'm afraid we don't check that often enough. So just how far can we go with AI? How will it impact upon education and learning and teaching in the future, do you think? I think the impact will be massive. It has started and it will evolve and I think it will have an impact on almost everything. Distance, no distance, people, humans, no humans, exams, no exams, permanent evaluation. You will be followed by an algorithm rather than by just some specific measures that are being taken. I think it will be very impressive. Massive, in one of the recent things that I have discussed with a professor, he generated a tool, he developed a tool that generates questions automatically based on text input. So that's where AI takes over the role of a teacher in creating knowledge, in creating exams, in creating questions. What I've seen was impressive, I mean the quality, let me retake, what I've seen was impressive that half of the questions was rubbish, but the other half was excellent quality really. The impact will be massive, I'm pretty convinced that is. But thank you for joining us today.
