AI tested as university exams undergo digital shift

For a couple of minutes earlier this 12 months, a university entrance examination disrupted Slovakia’s cellphone community. As Covid-19 unfold, Scio, a Czech schooling firm that manages entrance exams for greater than 80 schools at Czech and Slovak universities, switched from holding its exams in particular person to carrying them out on-line. But, throughout one examination in Slovakia, the third-party system it used crashed for greater than an hour, prompting hundreds of anxious college students to name Scio’s Czech hotline.“We had been advised that . . . for a couple of minutes on one supplier it wasn’t attainable to name Slovakia as a result of 10,000 folks had determined to name the Czech Republic to ask what was occurring,” says Martin Drnek, a supervisor at Scio.The episode was one of many many types of disruption brought on by the speedy shift from the bodily to the web world ushered in by the pandemic. Education worldwide has been thrown into chaos by Covid-19, with lockdowns and different disruption affecting greater than 220m tertiary-level college students, in response to Unesco, the UN’s cultural organisation. At universities, not solely have lessons moved on-line, however entrance exams have undergone a digital shift to adapt to a Covid-affected world.One of the largest challenges of such exams is that there are — or ought to be — no second possibilities. All candidates should take an examination underneath the identical situations and on the identical time, for the sake of equity and to keep away from questions leaking. So, now that exams are being performed on-line, synthetic intelligence and machine-learning know-how are being harnessed to determine and stop dishonest.After negotiating the primary 12 months of the pandemic utilizing software program supplied by different corporations, Scio developed its personal to check and monitor university candidates. It paired with Born Digital, a Czech start-up based by Tomas Malovec in 2019, which specialises in AI and machine studying strategies. The ensuing on-line examination system is because of go dwell this 12 months.

If we’ve on-line instructing, it’s good to simply accept college students who’ve expertise with on-line schooling and who know the way to work on-line

Beyond essentially the most fundamental downside of guaranteeing that the system is secure, one of many greatest challenges of switching to on-line exams, says Drnek, is familiarising college students with a system they could by no means have used earlier than — each in order that they will carry out to the most effective of their skills and so they don’t by chance do something that may very well be construed as dishonest.The software program, known as ScioHyperlink, addresses this in numerous methods, says Malovec. To spare college students any issues in downloading the software program to observe them throughout exams, it’s embedded within the examination webpage.Then, to make sure the suitable particular person is performing the check, ScioHyperlink pictures the candidate’s face and identification doc utilizing their webcam. It requires them to carry out a 360-degree scan of their environment by webcam, and screens their behaviour through the check by way of the webcam, together with the pc’s different methods, together with the microphone. If a candidate engages in actions deemed to be suspicious, the software program warns them in actual time.“In most circumstances, persons are not making an attempt to cheat. They simply don’t know they’re doing one thing forbidden. For instance, somebody calls they usually choose up their cellphone — it may very well be simply their mom asking them one thing,” says Malovec. “[If they are warned] they will appropriate it instantly.”If somebody is making an attempt to cheat, nevertheless, Born Digital’s AI mannequin has numerous methods of catching them. It can detect whether or not different persons are current within the room, and has been skilled to recognise if somebody is sporting earphones to be fed info. It also can recognise forbidden aids such as books or gadgets, such as smartphones and calculators — one thing Malovec says was not simple. “A cellphone is regularly only a black rectangle, so it’s not easy. There was a number of enjoying with issues like this [during development],” he says.


Born Digital’s software program doesn’t itself rule whether or not somebody has cheated. Instead, it alerts examiners to the purpose through the examination at which a possible breach occurred. This permits them to overview footage of the incident with out trawling by hours of in any other case unimpeachable examination conduct.Malovec says college students will probably be “ingenious” on the subject of evading the monitoring know-how, however factors out that the software program is all the time studying. He additionally predicts universities will more and more embrace on-line exams, saying that is solely the start of a interval of change.Juraj Mokry, vice-dean of the medical college at Comenius University in Bratislava, says on-line entrance exams also can point out whether or not candidates will be capable to address on-line instructing, which he expects to proceed as soon as the pandemic subsides. “If we’ve on-line instructing, it’s good to simply accept college students who’ve expertise with on-line schooling and who know the way to work on-line,” he says. “It’s not solely about excellence in chemistry and biology. It’s additionally testing how they will deal with issues with computer systems and every little thing.”However, he stops wanting arguing that on-line exams ought to utterly exchange in-person exams. “We ought to supply some variability,” he says. “Like with schooling, one particular person prefers to study from a display, one other from a textbook, one other prefers to pay attention. It ought to be the identical right here.”
