Several presenters presented their themes during the translanguaging virtual session. The seminar sought to improve participants' awareness of using more than one language in lecture rooms across the institution, particularly for tutoring and academics.
Language continues to be a barrier to access and success for many students at South African higher education institutions. Despite their status as official languages, indigenous languages have in the past and at present, structurally not been afforded the official space to function as academic and scientific languages.

Language policy for higher education seeks to address the challenge of the underdevelopment and underutilisation of official African languages at higher education institutions whilst simultaneously sustaining the standard and utilisation of languages that are already developed. 

The University of the Free State (UFS) Centre for Teaching and Learning hosted a multilingualism virtual seminar on 20 July 2022 that aimed to broaden an understanding of utilising more than one language within lecture rooms across the university, specifically for tutoring and academics. The following speakers presented various topics at the seminar:

Prof Makalela stated that the foundation of sustainable growth is excellent education, but the issue is, are we any closer to what one considers quality education? “You can’t, in my opinion. How can we know if you don’t examine epistemic difficulties at this level?” he further enlightened. 

Linguists believe that the practice of “translanguaging” can aid in learning, and the word has recently gained popularity in literature on bilingual and multilingual education with various universities incorporating these changes in their policies and to ensure that it’s all-inclusive as indicated by Dr Tolani Hlongwa. She further explained that languages are tools to navigate better understanding, whilst English should be used as a tool to communicate, not to measure intelligence.

What is the UFS’ role in addressing this?

The university’s language policy expresses its commitment to multilingualism, with particular emphasis on Sesotho, Afrikaans, and isiZulu. This policy ensures that language is not a barrier to equity of access, opportunity, and success in academic programmes or to access to the UFS administration. 

The UFS also developed an Academy for Multilingualism. This academy hosts the Multilingual Mokete, a popular annual tradition celebrating different cultural expressions in visual art, poetry, storytelling, drama, music, and songs by different language groups and in the different languages that are dominant at the UFS (i.e. English, Afrikaans, Sesotho, isiZulu, and Sign Language. 

In partnership with the University of Cape Town (UCT) and UKZN, the UFS will also conduct a Multilingualism Education Project colloquium on the new language policy framework for South African public higher education institutions on 28-29 September 2022. This language policy used in the new policy framework for public higher education institutions as well as its impacts will be examined in this virtual seminar. This is also an opportunity for diverse stakeholders to contribute suggestions on how to improve the existing status of language policy.

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.
