Enhancing students’ linguistic abilities

21 June 2023 | Story Amanda Tongha | Photo Samkelo Fetile

Language teaching professionals from across Southern Africa recently gathered at the University of the Free State (UFS) to discuss the need for benchmarking and standardising teaching and assessment practices.

With the aim of empowering lecturers and researchers responsible for language acquisition and delivering competent students to ensure their employability globally, the educators addressed the challenges of language acquisition in the region. It was the first time that educators from different language disciplines, including Dutch, German, French, Afrikaans, isiZulu, Sesotho, and Sign Language, met to discuss standardisation and best practices in teaching and assessment.

The symposium, which was hosted on the Bloemfontein Campus on 8 and 9 June 2023, brought together educators from the UFS, North-West University, University of Cape Town, University of the Western Cape, University of KwaZulu-Natal, University of Pretoria, Rhodes University, University of South Africa, Stellenbosch University, University of the Witwatersrand, University of Limpopo, and Sol Plaatje University. They were joined by participants from the University of Namibia and the National University of Lesotho, providing a regional perspective.

Standardising language acquisition in Southern Africa

Prof Angelique van Niekerk, Head of the Department of Afrikaans and Dutch, German and French, says the meeting marked a movement towards delivering competent students in order to increase their employability in languages such as Dutch, German, French, Afrikaans, isiZulu, Sesotho, and Sign Language.

“It is probably the first time that the different language disciplines and colleagues from disciplines involved in language acquisition in Southern Africa have met to discuss the need for benchmarking and standardising.”

“The symposium was not on multilingualism per se, but as language scholars, we support multilingualism. Social cohesion is affected positively if people and their culture and language are accepted and thus used.”

Talking about the need for a reference framework for benchmarking languages, Dr Michelle Joubert, Subject Specialist in the UFS Centre for Teaching and Learning, told delegates in her keynote address that a coordinated system provides a basis for the mutual recognition of language qualifications.

“Our aim is to develop a framework of standards for indigenous and foreign languages to reflect the political and social realities of a multilingual and multicultural South Africa, which aims to form a single South African education, employment, and residential space for its citizens.”

In another keynote address, Dr Carina Grobler, Subject Chair and Lecturer in French at the North-West University, highlighted effective assessment tools to enhance students’ ability to learn additional languages.

Prof Van Niekerk says many new initiatives, such as the sharing of resources on centralised platforms, were some of the gains following the symposium; a follow-up event is planned for 2024.

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.
