Online and distance-learning campus makes the most of a pandemic

Dr Joleen Hamilton - Johan Roux JRX December 2019 — Dr Joleen Hamilton is one of the faces behind the short learning programmes hosted on the UFS South Campus. Joleen obtained her PhD in December 2019.

This year may have been one of the most challenging since the higher-education industry started, but the UFS South Campus in Bloemfontein has not rested on its laurels when it came to putting its technology and expertise to use in supporting not only tertiary but also basic education. Here are three examples of a large array of short-learning and other courses or interventions hosted on this always-innovating campus.

Online and short learning

Since the South Campus is the university’s online, distance-learning, and e-Education (ODeL) hub, it was in the ideal position to take certain courses and convert them to online short-learning programmes (SLP). These included a Euclidean Geometry programme arranged with the Free State Department of Education (FSDoE). Study guides were printed and couriered to the teachers who participated, and WhatsApp groups were used as the primary communication tool. Participants could submit their assignments via email or WhatsApp. An online forms platform was used to facilitate registration, as well as for pre- and post-tests and evaluation of the SLP.

Another two courses were Harnessing Social Media (five weeks) and TeachOnline (sixteen weeks): these SLPs were developed during the lockdown. The goal of both was to equip teachers with the skills needed to use technology as a mode of instruction during times like lockdown. Harnessing Social Media is a basic course that focuses on social-media platforms such as WhatsApp as a teaching tool. TeachOnline is a more advanced SLP that shows you how to use Google Classroom effectively. All the assignments were also completed and uploaded on Google Classroom. A total of 150 teachers were accommodated in the above three SLPs.

IDEAS Lab lends a hand

The IDEAS Lab’s studios, which would usually host the Internet Broadcast Project, were made available to the FSDoE, and technical assistance was provided to record the trimmed Annual Teaching Plan (ATP). The IDEAS Lab furthermore designed and published a YouTube channel where their IBP videos could be uploaded; the IBP’s recording time and subjects were also increased. Computer hard drives were used to distribute videos to schools.

Community Engagement project in Sterkspruit

Despite the pandemic and national lockdown, there was no concern that the South Campus would be prevented from displaying a meaningful 67-minute act of love. The tight-knit family on this campus reached out to an early childhood development (ECD) centre in need close to Sterkspruit which has 15 learners. Being aware of their extremely limited resources, and how cold the winters get in that area, staff members under the inspiration of Nelia Oosthuizen and Prof Lynette Jacobs, have since September 2019 been knitting squares that are then sewn together to form blankets. Knitting was certainly also a form of therapy for the staff members involved, and when lockdown eased and we could give them the gifts of love, the young learners at this ECD centre knew that somebody in a place far from theirs took the trouble to make a colourful, comfy blanket stitch by stitch to keep them warm.

Gauteng teachers empowered

The South Campus is dedicated to delivering quality distance education to sectors of society that would not necessarily have access to higher education. Its flagship programme, the Advanced Certificate in Teaching (ACT), has been delivered across six provinces of South Africa to more than four thousand semi-qualified teachers over the past four years, thereby ensuring that qualified teachers deliver quality education in some of the country’s remotest areas.

The South Campus Formal Programmes division, in collaboration with the Gauteng Department of Basic Education, has identified teachers within that province who would benefit from additional training. Funding for the students’ tuition and ICT training was secured from ETDP-SETA through the Campus Principal, Dr Maria Madiope. In 2020, a total of 563 Gauteng students were funded at a comprehensive value of more than ten million rands.

Nanotechnology breakthrough at UFS

2010-08-19

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
