Dr Bernard
Dr Eleanor Bernard heads the Centre for Teaching and Learning on the Qwaqwa Campus.

“I realised that our students are not regularly exposed to and immersed in an English first language environment. So, for two years, I created control groups and tested how to implement a film club to support their language learning as well as engage them. In the end, I created a framework that university language teachers can use, with very specific guidelines as to how to make it successful.”

For her PhD study in Higher Education Studies, Dr Eleanor Bernard created a play on traditional learning by implementing a film club as a way of enhancing the basic interpersonal communicative and English literacy skills of non-native speakers on the Qwaqwa Campus. Dr Bernard is the Assistant Director of the Centre for Teaching and Learning on the Qwaqwa Campus. She will be graduating with her PhD in Higher Education Studies during the December 2021 graduations. The title of her study is: Implementing a film club to enhance English second-language students’ basic interpersonal communicative and basic English literacy skills.

Building on her passion for language learning and acquisition, Dr Bernard wanted her study to be a fun and interesting way of enhancing the already existing General English language module by creating a space for exposure and social interaction. She did this by forming student groups that would regularly watch films and opened spaces for engagement as a way of focusing on the language development of the students.

“The highlight for me was sitting in a university lecture venue, while watching Tsotsi or Pitch Perfect with students, and seeing them interacting, laughing, and enjoying a usually very serious space. Also, the wonderful discussions they shared on Blackboard around elements such as lobola, or stereotypes. Lastly, seeing how by the end of the year, they would walk into my office and interact with me more confidently in English,” she said.

Language studies has been a part of her academic journey from her Honours qualification. She has an MA degree in Language Studies from the UFS. She said working on the Qwaqwa Campus with language and literacy modules, she loved the process of watching students blossom as they gained more confidence in using the English language. “I especially love receiving a student at the beginning of the year, who you can see struggling and almost battling through the content and the skills. And then to see the change by the end of the year, and how their confidence increased.”

‘No learning can take place without engaging students’
She said she hoped faculties would also see the value of focusing on the language development of students as a baseline for academic literacy skills development.

“No learning can take place without engaging students, and there are so many guidelines and practical ways to ensure this engagement, including in language learning. Student success is not just about performance or final marks, but also about students completing a year where they have interacted with others and learned to care for them, where they have been changed to want to impact societies and communities, and where they have acquired skills that they will use when they enter the world of work.”

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.
