Statement by Prof Francis Petersen, Rector and Vice-Chancellor

The university’s executive management is aware of the statement on COVID-19 alert Level 2 measures in the post-school education and training sector delivered by the Minister of Higher Education, Science and Innovation, Dr Blade Nzimande, on 26 August 2020.

During the statement, Dr Nzimande indicated that the University of the Free State (UFS) is one of six universities that is deemed to be at medium risk of not completing the academic year. The statement was surprising and disappointing, since through an engagement between the Department of Higher Education and Training (DHET) and the UFS almost a week ago to understand the university’s approach to the completion of the 2020 academic year, as well as the interpretation of specific information provided by the university in its COVID-19 Responsiveness Multi-modal Teaching and Learning Programme to the DHET, the DHET was clear that the UFS was not at a medium risk, but indeed at a low to very low risk of not completing the academic year.

Since the statement by Dr Nzimande, I received a letter from the Deputy Director-General: University Education at the DHET, Dr Di Parker on 28 August 2020 confirming that the university’s risk rating has been adjusted to a low risk rating. The DHET also recognised the good work done by the UFS towards successful completion of the academic year. 

Let me explain why the DHET delegation expressed its opinion that the UFS was at a low to very low risk of not completing the academic year. The UFS has taken an evidence-based approach to managing the impact of the pandemic. Within the first weeks of the national lockdown, the Special Executive Group (SEG) was formed, which meets weekly to discuss various aspects of the institution’s operations and to forecast and plan the impact of the pandemic. As the university’s COVID-19 nerve centre, the SEG has several task teams, one of which is the Teaching and Learning Management Group (TLMG).

The core function of the TLMG was to ensure that teaching and learning could continue to help staff and students to successfully complete the academic year. The first step in the evidence-based response was to conduct a survey among UFS students to assess their access to devices and data. Altogether 13 500 students responded to the survey. The results showed that 92% of students had an internet-enabled device, 70% could get access to the internet off campus, and 56% had access to a laptop.

Based on this evidence, we immediately initiated the purchase of 3 500 laptops to be distributed to NSFAS- and Funza Lushaka-funded students and students with disabilities. In addition, the Keep Calm, #UFSLearnOn, and #UFSTeachOn campaigns have been launched. These campaigns are aimed at creating the best possible support for academic staff and students, respectively by adapting existing support and practices most suited to an emergency remote-learning environment. The departure point of both campaigns was to design a response for the constrained environments of our students.  

The #UFSLearnOn campaign for students creates materials that students can download on their cellphones and that would provide them with skills and ideas on how to get connected and create an environment where they could study at home. The #UFSLearnOn website has been viewed by 77 000 students to date; the resources were shared with other universities to support a collaborative approach to addressing the COVID-19 challenge. In addition, 177 000 Facebook users have been reached by #UFSLearnOn materials.

The #UFSTeachOn campaign focused on supporting staff to transform their materials and teaching approach to a new reality. Altogether 1 409 staff members attended training sessions, which all ran overtime due to the commitment of staff to create the best possible response. Both the #UFSLearnOn and #UFSTeachOn campaigns are continuing, with an overwhelmingly positive response from our staff and students. 

However, these campaigns would become two of the 16 strategies the university has developed to manage the risks created by the pandemic. Creating responses is, however, not enough – evidence is needed to make a difference. Therefore, the Centre for Teaching and Learning (CTL) was tasked with creating a monitoring system using data analytics. To date, 26 reports have served at the weekly TLMG meetings. The reports monitor the number of staff and students on the Learning Management System, how much time they are spending on learning, and whether they are completing assessments. 

During the peak of the first semester, 90% of students were supported online by academic and support staff. The average performance of students per faculty per campus has been monitored. The use of data analytics allowed us to identify students who were not connecting, as part of the No Student Left Behind initiative. Out of the 41 000 students at the UFS, 989 students were identified who had not connected with learning. These students were contacted individually and to date, 80% of these students have been helped to connect. Additional plans are being developed to support the other 20% to plan for the successful continuation of their studies. The success of our approach is not only borne out by quantitative evidence, but also by qualitative feedback such as the following quote received by an academic adviser on 24 August 2020:

“Thank you so much [advisor’s name]; if it wasn't for you, I would have dropped out, deregistered, or even committed suicide during this pandemic. I want to say that I have passed all my modules with distinctions, all thanks to you. After all the difficulty of learning I have experienced during this period. Please continue your great work to others (you were truly meant for this job), and God bless you.”

There are hundreds more quotations like these that testify to the inspiring efforts of our students and staff to finish the academic year successfully with very low risk. 

The UFS will continue with its project management and risk-adjusted management approach and is fully committed to ensure that no student is left behind and that the 2020 academic year is successfully completed.

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.
