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.”

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
