Opinion article by Dr Peet van Aardt, Centre for Teaching and Learning and Head of the UFS Writing Centre, University of the Free State. 


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.

UFS boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
