Ria de Villiers_web read more — 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.”

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including: Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained. The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5. The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small. In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
