The use and permittance of artificial intelligence tools such as ChatGPT at the University of the Free State (UFS) should be discouraged, writes Dr Peet van Aardt.

A decade ago, academics were encouraged to find ways to incorporate social media platforms like Facebook and Twitter in their teaching. Seeing as students were spending so much time on these platforms, the idea was that we need to take the classroom to them. Until they found out young people do not use social media to study, but rather to create and share entertainment content.

During the late 2000s, News24.com, the biggest news website in Africa, went on a mission to nurture and expand what was known as “community journalism” because everybody started owning smartphones, the news outlet’s leadership thought it was the opportunity to provide a platform for people to share photos, videos and stories of news events that took place around them. Until they realised that the vast majority of people didn’t want to contribute to journalism; they merely wanted to consume it.

Lest we assume students will use AI in a responsible and productive manner, at the UFS Writing Centre we find that students over-rely on ChatGPT in their assignments and essays. We should do everything in our power to discourage its use because it threatens what we do at a university on three levels.

It’s an educational issue

There are five main academic literacies we want to teach our students: reading, writing, speaking, listening and critical thinking. When students prompt ChatGPT to write their essay for them, immediately the reading and writing literacies are discarded because the student does not write the essay, nor do they read any source material that would help them form an argument. Critical thinking goes out the window, because it is merely a copy-and-paste job they are performing. And speaking? We see in the Writing Centre that students who use ChatGPT cannot discuss their “work”. The student voice is being killed.

There are lecturers who take the approach of motivating students to use prompted content from ChatGPT in order to critique and discuss the AI output. This is fine, should the students be operating at a level where their academic literacies have been established. In short: for postgraduate use it might be acceptable. Undergraduate students need to go through the process of becoming scholars and master their subject matter before they can be expected to critique it. It is basic pedagogy, and our duty as staff at the UFS, because it aligns with the Graduate Attribute of Critical Thinking.

It’s a moral issue

In addition to the academic literacies we attempt to instil in our students are attributes of ethical reasoning and written communication. The fact that AI tools “scrape” the internet for content without any consent from the content creators means that it is committing plagiarism. It is theft – “the greatest heist in history” as some refer to it. Do we want our students to develop digital skills and competencies on immoral grounds? Because often this is the reason given when students are encouraged or allowed to use AI: “The technology is there, and therefore we must learn to go with the flow and let the students to use it.” By this reasoning one can make the argument that the UFS rugby team (go, Shimlas!) must use performance-enhancing substances because it will make the players faster, stronger and “the technology is there”.

Academics also face a moral dilemma as there seems to brew a view that fire should be fought with fire: that AI can assist and even lead in tasks such as plagiarism detection, assessment and content development. But fighting fire with fire just burns down the house. Let us not look to AI to lessen our workload.

It’s an economic issue

Technology in education should be used to level the playing field. Companies develop online tools with a primary goal of making money – despite what the bandwagon passengers in the East and West promise us. Their operations cost a lot of money, and so they release free versions to get people hooked on it, and then they develop better products and place them behind a paywall. What this then means is that students who can afford subscription costs get access to the premium product, while the poor students get left behind. How can we assess two students who cannot make use of the same version of a tool? This will widen the gap in performance between students from different economic backgrounds. And consider the deletion of the authentic student voice (as alluded to earlier), these AI tools just represent a new platform for colonisation and therefore have no place in our institution.

OK, so what?

Lecturers who want advice on how to detect overreliance on AI tools can have a look at this video, which forms part of the AI Wayfinder Series – a brilliant project by the UFS’s Interdisciplinary Centre for Digital Futures and the Digital Scholarship Centre. These centres also have other helpful resources to check out.

But as an institution we need to produce a policy on how to deal with the threat and possibilities of AI. (Because in society and in certain disciplines it can make a contribution – just not for undergraduate studies in a university context.) Currently, a team that includes staff from the Faculty of Law and that of Economic and Management Sciences is busy drafting guidelines which departments can implement. Then, after a while, a review of these guidelines-in-practice can be done to lead us on the path of establishing a concrete policy.

If we as educators consider the facts that the use of AI tools impede the development of academic literacies (on undergraduate level), it silences local, authentic voices and it can create further economic division among our student community, we should not promote its use at our institution. Technology is not innovative if it does not improve something.

NRF grants of millions for Kovsie professors

Two professors received research grants from the National Research Foundation (NRF). The money will be used for the purchase of equipment to add more value to their research and take the university further in specific research fields.

Prof Martin Ntwaeaborwa from the Department of Physics has received a R10 million award, following a successful application to the National Nanotechnology Equipment Programme (NNEP) of the NRF for a high-resolution field emission scanning electron microscope (SEM) with integrated cathodoluminescence (CL) and energy dispersive X-ray spectrometers (EDS).

Prof Bennie Viljoen from the Department of Microbial, Biochemical and Food Biotechnology has also been awarded R1,171 million, following a successful application to the Research Infrastructure Support Programme (RISP) for the purchase of a LECO CHN628 Series Elemental Analyser with a Sulphur add-on module.

Prof Ntwaeaborwa says the SEM-CL-EDS’ state-of-the art equipment combines three different techniques in one and it is capable of analysing a variety of materials ranging from bulk to individual nanoparticles. This combination is the first of its kind in Africa. This equipment is specifically designed for nanotechnology and can analyse particles as small as 5nm in diameter, a scale which the old tungsten SEM at the Centre of Microscopy cannot achieve.

The equipment will be used to simultaneously analyse the shapes and sizes of submicron particles, chemical composition and cathodoluminescence properties of materials. The SEM-CL-EDS is a multi-user facility and it will be used for multi- and interdisciplinary research involving physics, chemistry, materials science, life sciences and geological sciences. It will be housed at the Centre of Microscopy.
“I have no doubt that this equipment is going to give our university a great leap forward in research in the fields of electron microscopy and cathodoluminescence,” Prof Ntwaeaborwa said.

Prof Viljoen says the analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilises a combustion technique and provides a result within 4,5 minutes for all the elements being determined. In addition to the above, the machine also offers a sulphur add-on module which provides sulphur analysis for any element combination. The CHN 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal and fuel oils, as well as some inorganic materials such as soil, cement and limestone.

The necessity of environmental protection has stimulated the development of various methods, allowing the determination of different pollutants in the natural environment, including methods for determining inorganic nitrogen ions, carbon and sulphur. Many of the methods used so far have proven insufficiently sensitive, selective or inaccurate. The availability of the LECO analyser in a research programme on environmental pollution/ food security will facilitate accurate and rapid quantification of these elements. Ions in water, waste water, air, food products and other complex matrix samples have become a major problem and studies are showing that these pollutants are likely to cause severe declines in native plant communities and eventually food security.

“With the addition of the analyser, we will be able to identify these polluted areas, including air, water and land pollution, in an attempt to enhance food security,” Viljoen said. “Excess levels of nitrogen and phosphorous wreaking havoc on human health and food security, will be investigated.”
