For the past two years, students in tertiary institutions have had to negotiate the choppy waters of emergency online tuition. In February, thousands of students at universities across the country will be returning to the shores of face-to-face learning. But it will require a process of reconnection that may take time and will have to be guided sensitively, says Prof Francis Petersen.


It is a fact of life that, in so many spheres, one’s journey is often as memorable – sometimes even more so – than one’s experiences at a destination. The South African education context is no exception. Many of us grew up with stories of parents and grandparents expanding at length about their difficult journeys to school ‘back in the day’. Some of the details of what happened inside the classroom may have faded over time, but the journey often remains etched in memory. Journeys that tell of sacrifice, of braving harsh weather and long distances – often on foot. A great victory already lies, after all, in the mere process of getting somewhere. 

The Online Move

There is little doubt that online tuition was a vital lifebuoy for education during the pandemic and lockdown, and that it will form an increasingly important part of our future educational landscape. The huge digital divide that the move to online education has exposed, remains a most pressing concern that needs to be addressed urgently in order to ensure that students from all socio-economic sectors and both rural and urban environments can access online resources. 

One consequence of online learning that is maybe not deliberated as frequently, is that it has essentially eliminated the need for a journey – in this case, the physical journey to a tertiary education campus. Once again, this fact comes with many perceived advantages: no transport costs, no travelling time, no risk associated with moving out of one’s comfort zone. Provided you have access to sufficient resources and connectivity (a topic for another time!), and provided you have a safe home environment conducive to learning (which many of our students sadly lack), it has become incredibly easy and convenient to access education – anytime, anywhere, and at your own pace.

But there are some aspects that can become complicated in the absence of a physical journey. 

Because journeys imply a few things:

A Journey Requires a Deliberate Decision About a Destination

People go on journeys because they want to get somewhere. They decide where they want to end up and then take the steps necessary to get there. The physical journey to a place of learning, of course, also reflects a more figurative journey towards an envisaged career and a successful future.  

Over the past two years, students have often reported feeling as if they were ‘drifting’ in the online environment, not always sure where they were heading, feeling a bit lost and disconnected. Maybe part of the reason for this lies in the fact that they were not physically going anywhere.  Without this physical aspect of the journey, it can become difficult to plot yourself, and difficult to convince yourself that you are moving ahead and making progress.

A Journey Requires a Measure of Sacrifice

A journey also almost always implies sacrifice in some form. Whether it is getting up early to catch a train, a bus, or two taxis to university, incurring fuel costs or transport fees, or just strolling to class across campus from your residence – a successful journey requires discipline and planning. And it takes some form of sacrifice of time and resources. 

Which brings me to the next point: 
 
A Journey Requires Commitment 

It takes commitment to make those sacrifices needed to complete a journey. And in turn, sacrifice fuels commitment. As human beings, we tend to treasure those things that were hard to obtain, and we do our utmost to hold on to them. The opposite of ‘easy come, easy go’, is equally true. It is often just as easy for students to opt out of online learning sessions, as it is to access it. And this is where the problem sometimes lies: commitment is not really tested or strengthened. 

Gaining Courage from Fellow Travellers

Probably the most poignant aspect of the journey analogy, is the fact that it makes you aware of other travellers. The students treading the campus pavements with you, passing you in passages, walking with you into class, are a constant reminder that your journey is not a solitary one. Fellow travellers – and fellow students – reaching out to one another, sharing tips and experiences, make the journey easier for everyone. Interacting with others and knowing that we are not alone, is a vital part of what makes us human, what makes our journeys meaningful.

Dealing with Fear

Countless COVID-19 research projects from all over the world seem to point to one basic bottom line: the absence of physical interaction has taken a huge psychological toll on most of our students. However, psychologists working on our campuses report a significant increase in students seeking psychological help in the run-up to the restart of contact learning. They say some students find the prospect of returning to campus stressful and even terrifying. It is a move that will take them outside their new comfort zones. Many students relate how they have been living in an ‘artificial online world’ for the past two years – not only academically but socially too. Students who used to be very sociable have been spending their non-academic time behind screens too, engaged in gaming, streaming services, and social media. Two years was long enough to blur memories of what used to be normal. Long enough to entrench new habits – not all of them conducive to good mental health – which can take time to change. It was also long enough to desensitise students to what they really need and want.

Psychological Support for Students

The value of providing our students with different forms of psychological support during these unusual and uncertain times cannot be overemphasised. At the University of the Free State (UFS), the various support initiatives we have implemented and expanded over the past two years have undoubtedly contributed to the fact that we could complete the academic years of 2020 and 2021 successfully. Among these initiatives are a 24-hour toll-free mental-health careline as well as an e-mentoring programme that offers socio-emotional support to students. Data analytics revealed that more than a third of our students engaged in these support interventions, and we see it as a major reason that, despite all the obvious challenges, we still managed to improve our overall institutional success rate in 2020 and 2021.  

Social Interaction a Basic Need

As tertiary institutions, we need to not only focus on what is convenient for our students at this time, but on what they actually need. And as human beings, we need social interaction. We need to read social cues, expressions, and body language, hear voice intonation, and where possible and appropriate, touch and feel. University life is, after all, about so much more than just attending classes. It is about engaging in sporting and cultural activities, about honing your interests, and finding new ones. It is about learning to collaborate and building networks and support groups, about forming friendships, and entering relationships. And sometimes, it is about just having fun.

Returning to Campus

Most universities are currently introducing some form of blended learning programme, combining online and face-to-face tuition. At the UFS, 67% of our modules on offer will be in a face-to-face format (at least in the early part of 2022), with the necessary COVID-19 protocols in place to ensure a safe environment for staff and students. As we welcome our students back on campus, it is vital that we as university leadership carefully and effectively remind them that their study years should be a holistic experience, encompassing different aspects of their being. We should encourage them to make use of the precious reconnection opportunities with those around them. And be patient as they negotiate their way in an old-but-new environment.

Let the journey begin.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
