CTL Conference 2023
UFS staff took part in the panel presentation and panel discussion at the pre-conference workshop on graduate attributes and employability.

The University of the Free State (UFS) recently hosted its annual Teaching and Learning Conference, bringing together educators, students, and thought leaders across the educational spectrum.

This year’s conference focused on reshaping the future of education, emphasising blending traditional teaching methods with innovative technologies to nurture essential graduate attributes through thoughtful, intentional assessment design.

The programme was spread over five days, from 11 to 15 September 2023, and was themed ‘Quality blended learning and teaching: Enhancing graduate attributes through assessment’. It kicked off with two pre-conference workshops: one on graduate attributes and employability, on 11 September, and one on alternative assessment, on 12 September.

The conference served as a platform for sharing ideas and strategies to elevate the quality of education, ultimately enriching students' learning experiences. Discussions revolved around creating adaptable, career-ready graduates capable of navigating an ever-evolving job market. 

Graduate attributes and employability

Cathy Sims, Executive Director of the South African Graduate Employers Association (SAGEA), emphasised the institution's importance in facilitating a seamless transition for students from academic institutions to the workforce. She also highlighted the need for collaboration between the institution and employers to ensure that students are equipped with necessary and scarce skills across various industries.

"Institutions must prioritise cultivating graduates with a well-rounded skill set, encompassing technical expertise and strong interpersonal abilities,” she said. “This can be achieved through thorough research and robust partnerships with employers. I admire the proactive approach taken by UFS in this regard, with [UFS Vice-Chancellor and Principal] Prof Francis Petersen actively participating in numerous panel discussions. Events like the 2023 Investing in Mining Indaba exemplify the kind of conversations that address the skills gap head-on."

The panel presentation by lecturers from different faculties highlighted the work being done to promote graduate attributes at the UFS. During the panel discussion led by Prof Francois Strydom, Senior Director at the UFS Centre for Teaching and Learning (CTL), lively discussions were held around bridging the gap between industry needs and higher education efforts, as well as practical ways to prepare students for the world of work.

Looking to the future

Attendees heard that the rapidly growing use of technology and applications like ChatGPT has led to a transformative shift in teaching and learning at educational institutions, helping to foster innovative and efficient ways to educate and empower students. However, Prof Johannes Cronjé, from the Department of Information Technology at the Cape Peninsula University of Technology, expressed concerns regarding an overreliance on technology, which may lead to the removal of interpersonal skills and understanding of context. 

Following the keynote address by Prof Cronjé, Dr Peet van Aardt and Zonnike Coetzer from the CTL addressed ways to deal with ChatGPT in teaching academic literacy. The rest of the programme was dedicated to creative ways to use ChatGPT in assessment, presented by Dr Ina Gouws from the UFS’s Faculty of Humanities, and a practical session on redesigning a module by Dr Michael von Maltitz, from the UFS's Faculty of Natural and Agricultural Sciences.

The two pre-conference days paved the way for the virtual conference, which took place from 13 to 15 September via Blackboard Collaborate. The keynote speakers for each of the conference days focused on the theme and provided much food for thought. 

On the first conference day, Prof Jillian Kenzie of Indiana University, USA, provided a fresh perspective on how assessment can be used to assure student learning and success. Dr Muki Moeng of Nelson Mandela University started the second day with a discussion on graduate attributes. She highlighted that the higher education sector is faced with worldwide challenges such as rapid technological changes, political turbulence, decolonisation of the curriculum, climate change, and more. Higher education should respond to these changes and reinvent itself while trying to stay true to what a university is “understood to be”, and how it should look in the contemporary world.

Prof Corlia Janse van Vuuren of the UFS’s Faculty of Health Sciences was the keynote speaker on the last day. She talked about the continued theory-practice gap and questions raised regarding the relevance of teaching and learning. “Universities might need to reflect on whether all stakeholders, specifically students, are moving towards the same goal concerning the development of graduate attributes,” she said.

During the conference UFS staff members also showcased the innovative and excellent work they are doing in learning and teaching: 53 papers were delivered in seven different categories over the three conference days.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
