Dr Ria de Villiers is passionate about education as a vehicle to ensure that people are fully engaged in work and life.

The world is rapidly changing, and the Department of Education (DBE) is responding with a plan that aims to prepare learners to adapt to a new world. Ecubed (E3), a DBE programme using playful project-based learning as a learning methodology, unlocks an entrepreneurial mindset in school learners. The E3 programme focuses on entrepreneurship, employability, and education, emphasising learning as a lifelong process. Dr Ria de Villiers is the Curriculum and Schools’ Implementation Manager for E3.

Dr De Villiers, an alumna of the University of the Free State (UFS), is passionate about education as a vehicle to unlock competencies and agency, ensuring that people are fully engaged in work and life. Dr De Villiers therefore invests great effort in contributing to a more relevant education system. “I feel compelled to do something about the challenges we see in education, especially since it is such a vital part of our human (and societal) development,” she says. 

Loving the buzz at schools, the smell of dust and chalk, Dr De Villiers really has a heart for teachers. “Teachers are often unacknowledged, and the work they do is critical,” she believes. She realised that as a teacher, her reach was too small to solve the problems in the South African education system. Therefore, she works as a teacher trainer, where she feels she can have a broader impact.

Her work as implementation manager for E3 allows her to make a positive impact on the education sector, while managing the creation of new learning materials online and face to face, as well as working in teacher development.

The difference in a changed world

Talking about E3, she says the programme prepares learners to acquire skills, knowledge, attitude, and mindset to be business owners or employers while being lifelong learners. The traditional way of teaching is changing, and with skills acquired through the E3 programme, school leavers will be ready to attend a tertiary institution, be prepared for the job market, and/or be able to start a business.

This is not the first time that Dr De Villiers has found herself in the education arena. She received her doctorate in Applied Linguistics from the UFS Faculty of the Humanities under the supervision of Prof Willfred Greyling in the Department of English. Her dissertation was titled, The impact of a discourse-based teacher counselling model in training language teachers for outcomes-based education. Assisting government and teacher unions with the training of teachers helped her to obtain the data for her PhD, in which she proposed a teacher-counselling model to promote teacher efficacy and agency. 

Teaching across borders

A big part of her career was spent in the education environment, although she worked as a businesswoman and freelance consultant for more than 30 years – first as teacher and university lecturer, and later as co-founder of Future Entrepreneurs, a publishing and teacher-support business. 

But it was when she started a language school that her communication business, Jika Communication and Training, came into being; it was not long before this enterprise developed into a leading training organisation for entrepreneurship education programmes endorsed by the International Labour Organisation (ILO). Together with the ILO, she worked on a series of 30 business simulation games and role-plays to promote progressive teaching methodologies, learner-centredness, and activity-based experiential learning. 

Teaching others about learning also allowed Dr De Villiers to cross South African borders when she facilitated the reworking of the vocational curriculum for the Indonesian government. She has done training at all teacher-training colleges in Dar-es-Salaam and Zanzibar for the Ministry of Education in Tanzania. 

A more humane, learner-centred approach

In our changing world, and as it pertains to the education system, Dr De Villiers truly believes that training and teaching needs a more humane, learner-centred approach, with mutual respect between trainer and learner. 

She remains inspired to continue making a difference in the sector. “I want schooling to improve and gear itself for a rapidly changing world. I want young people who are out of work to find their voice and place in the economy. I want every school learner to develop the agency and confidence to stand up in class and ask a question without any fear of losing face. And I want teachers to develop that agency too as they become more and more autonomous, self-reliant, and confident enough to teach using progressive methodologies.”

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.
