UFS CTL Teaching and Learning Conference
The University of the Free State (UFS) recently held its annual Teaching and Learning Conference. The theme of this year’s conference was Celebrating excellence in learning and teaching, coinciding with the Centre for Teaching and Learning’s (CTL) 10-year celebrations.

The University of the Free State (UFS) recently held its annual Teaching and Learning Conference which began with three pre-conference workshops on the Bloemfontein Campus on 12 and 13 September and ended with a virtual conference hosted from 14 to16 September 2022.

The aim of the UFS Learning and Teaching Conference is to provide academics and academic support staff the opportunity to showcase their innovative learning and teaching practices within different disciplines, as well as to advance the scholarship of teaching and learning at the institution. The theme of this year’s conference was Celebrating excellence in learning and teaching, coinciding with the Centre for Teaching and Learning’s (CTL) 10-year celebrations. During the pre-conference workshops, the focus was on blended learning, curriculum development, and student engagement. 

Dr Engela van Staden, Vice-Rector: Academic, opened the virtual conference on 14 September. She highlighted that universities contribute to the country’s economy through the type of graduates they produce. Therefore, the lecturers are vital; they must use various learning and teaching strategies and diligently perform their jobs to prepare students for the world of work. 

“We must stay current and grasp new advancements in our discipline and teaching methods. These techniques should also recognise students' diversity and multilingualism. With the new Language Policy, we should ensure that our dominant languages are used in academia in years to come. We are here to assist students in becoming employable graduates, and one of the elements that CTL has embarked on is the support we are receiving from them through various programmes, such as Enterprising your Degree: ePortfolio Development (EDED), which provides our students with platforms to market themselves in many professional fields,” Dr Van Staden said. 

Furthermore, Dr Van Staden emphasised the importance of research in enabling and empowering students to remain relevant. COVID-19 has also demonstrated the importance of the teaching approach and tested its efficacy in the classroom. This has resulted in the UFS moving towards becoming a digitalised institution. She stated that the institution has an agreement with the Free State Department of Health to conduct robotic surgery. She further explained that this is not about replacing academics, but about improving teaching and learning. 

In his welcoming address on the second day of the virtual conference, Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, said that the reduction of the achievement gaps between a diverse group of people over the past decade demonstrates that the UFS is not just talking about innovation, equity, quality, and success, but about walking the talk – practically implementing what they profess, to make a real difference in the lives of the students, and to ensure the relevance of the institution.

“During the COVID-19 pandemic, the effective use of advanced data analytics was one of the contributing factors that enabled us to transition to an online learning and teaching environment successfully. It has allowed us to identify a lack of participation in online tuition, to reach out to individual students at risk, and respond with appropriate support mechanisms – thereby ensuring student success,” Prof Peterson added.

He further explained that Vision 130 commemorates 130 years of the UFS’ existence and is also a strategy to reposition the university for 2034 to ensure stability and clarity for planning and decision-making, while leaving scope for adaptation and agility. This vision will, among other things, promote 
• academic excellence, quality, and impact;
• maximum societal impact with sustainable relationships; and
• a diverse, inclusive, and equitable university.

Sizofunda Ngenkani: The Politics and Voice and Merit Principles in Higher Education

Prof Pearl Sithole, Vice-Principal: Academic and Research on the Qwaqwa Campus – one of the keynote speakers – asked, “What impact does our education have on the world? Consider our social enterprise. This demonstrates that there are stumbling blocks that prevent us from learning. We understand that education is a two-way street – capabilities and quality of access. Much has been done to demonstrate that education is more than a classroom endeavour, yet something must explain why education has failed to have the intended influence in societies. This is targeted at the interaction between society and education, and as academics, we are up to the task to ensure that these issues are solved through various programmes.”

Building future excellence through scholarship, collaboration, and action for impact

In his keynote address, Prof Francois Strydom, Senior Director: CTL, presented some of the strategies that have contributed to CTL’s success since its inception in 2012, despite some of the challenges that institutions of higher learning encountered. 

“Scholarships, collaboration, and action have always been instilled in us. We have integrated higher education research, organisational development, and management literature, considering international and national institutional viewpoints and settings. We acknowledge and promote faculty contributions and the dedication of teaching and learning managers who are supported by deans and academics to enhance the quality of teaching and learning,” said Prof Strydom.
He also emphasised the different programmes and research that contributed to this result. There are 223 national and 52 international conference papers, 288 research reports, two books, 93 articles/book chapters/peer-reviewed conference publications, and 35 postgraduate student supervisions.

Following the conference, the centre will be hosting its annual teaching and learning awards event on 12 October 2022 to recognise and award the excellent work done in learning and teaching at the UFS.

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.
