Remote Teaching and Learning during COVID-19

The COVID-19 pandemic has created profound disruptions in our economy and society. Due to the challenges of this pandemic, most universities have decided to move from face-to-face classes to online teaching (more accurately defined as emergency remote teaching and learning) so as to complete the 2020 academic year, and to prevent the spread of the virus.

Online learning vs emergency teaching and learning

Online learning is the result of careful instructional design and planning, using a systematic model for design and development. With remote emergency teaching and learning, this careful design process is absent. Careful planning for online learning includes not just identifying the content to be covered, but also how to support the type of interactions that are important to the learning process. Planning, preparation, and development time for a fully online university course typically takes six to nine months before the course is delivered.

Emergency teaching and learning is a temporary shift of instructional delivery to an alternative delivery mode due to crisis conditions. Hence, one cannot equate emergency remote teaching and learning with online learning, nor should one compare emergency remote teaching and learning with face-to-face teaching. What is crucial is the quality of the mode of delivery, and although assessment methodologies will differ between face-to-face teaching and remote teaching and learning, the quality of the learning outcomes should be comparable.

Funding to universities

The financial model used in a South African (residential) university consists of three main income sources: (i) the state or government through a subsidy (the so-called ‘block grant’), (ii) tuition fees, and (iii) third-stream income (which is mainly a cost-recovery component from contract research, donations, and interest on university investments). The National Student Financial Aid Scheme (NSFAS) contributes to the tuition fees through a Department of Higher Education, Science and Innovation Bursary Scheme, providing fully subsidised free higher education and training for poor and working-class South Africans (recipients will typically be students from households with a combined income less than R350 k per annum).

The negative impact of COVID-19 on the income drivers of the university can, and probably will, be severe. Although the subsidy from the state or government can be ‘protected’ for a cycle of two to three years through the National Treasury, the pressure on income derived from tuition fees (that component which is not funded through NSFAS) will be increasing, as households would have been affected by the nationwide lockdown and with the economy in deep recession, a significant number of jobs would have been lost. The economic downturn, due to both COVID19 and a sovereign downgrade by all rating agencies, has already negatively impacted local financial markets as well as the global economy. The multiplier effect of this would be that the value of investments and endowments decreases (at the time of writing the JSE was still 20% down compared to the previous year), and philanthropic organisations and foundations will most probably reduce or even terminate ‘givings’ to universities.

Industry, private sector, and commerce will re-assess their funding to universities, whether for research or bursary support. Overall, it is possible that the income sources for universities can be affected negatively in the short term, but it will definitely have longer-term implications on the financial sustainability of universities. In this regard, it would be important for universities to perform scenario planning on the long-term impact of COVID-19 on the financial position of the university, and to adjust their strategic plans accordingly.

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.
