The UFS has taken an evidence-based approach to managing the impact of the COVID-19 pandemic. Within the first week of lockdown, the Rector and Vice-Chancellor, Prof Francis Petersen, put appropriate governance structures in place, consisting of a COVID-19 Senior Executive Team and seven task teams focused on managing the different aspects and responses to the pandemic. One of these task teams was the Teaching and Learning Management Group (TLMG), chaired by the Vice-Rector: Academic, Dr Engela van Staden. This multi-stakeholder group represents all the environments in the university responsible for teaching, learning, and support to the academic core.

The core function of the TLMG was to ensure that teaching and learning could continue in order to help staff and students to complete the academic year successfully. The first step in the evidence-based response was to understand students’ device access, data access, and connectivity.  The Centre for Teaching and Learning (CTL) developed a survey to which 13 500 students responded. The results showed that 92% of students had an internet-enabled device, 70% could get access to the internet off campus, and 56% had access to a laptop.

The survey was followed by the Vulnerable Student Index (VSI) developed by the Directorate for Institutional Research and Academic Planning (DIRAP), which helped the university to create a better understanding of the vulnerability of about 22 000 students at the UFS. 

#UFSLearnOn is born

Based on VSI results, the UFS immediately initiated the purchase of 3 500 laptops to be distributed to assist more students. In addition, the #KeepCalm, #UFSLearnOn and #UFSTeachOn campaigns were launched. These campaigns are aimed at creating the best possible support for academic staff and students respectively, by adapting existing support and practices most suited to an emergency remote-learning environment. The departure point of both campaigns was to design a response for the constrained environments of our students. 

The #UFSLearnOn for students creates materials that students can download on cellphones and that would provide them with skills and ideas on how to get connected and create an environment where they could study at home. The #UFSLearnOn website has been viewed by more than 77 000 students to date, and the resources were shared with other universities to support a collaborative approach to addressing the COVID-19 challenge. A total of 177 000 Facebook users have been reached by these #UFSLearnOn materials.

The #UFSTeachOn campaign focused on supporting staff to transform their materials and teaching approach to a new reality. Staff members who attended training sessions numbered 3 800, a testament to their commitment to create the best possible response. Both the #UFSLearnOn and #UFSTeachOn campaigns are continuing, with an overwhelmingly positive response from staff and students.

Multi-pronged approach

However, these campaigns would become two of the 16 strategies the UFS has developed to manage the risks created by the pandemic. Creating responses is, however, not enough; you need evidence that these initiatives are making a difference. Therefore, the CTL was tasked with creating a monitoring system using data analytics. To date, 34 reports have served at the weekly TLMG meetings. The reports monitor the number of staff and students on the Learning Management System (LMS), measuring how much time they are spending learning, and whether they are completing assessments. 

During the peak of the first semester, 90% of students were online, supported by academic and support staff. The average performance of students per faculty per campus was monitored. The use of data analytics allowed the UFS to identify students who were not connecting, as part of the #NoStudentLeftBehind initiative. 

A ‘no-harm intervention’

Gugu Tiroyabone, Head of Advising, Access, and Success in CTL, says that this intervention was designed to effect behavioural change while not scaring a student, in an effort to enhance chances of success: “Under the banner of No Student Left Behind (NSLB) at the UFS – a ‘no-harm intervention’ – the task team continuously reflects on the numbers, which provides insights on student behaviour relating to access/engagement on the LMS system. The quantitative data is integrated with students’ qualitative narratives to tailor individualised responsive support through academic advising, tutorial support, and other student-support services in faculties and student affairs. The NSLB was one of many other faculty and institutional initiatives deployed during the pandemic to promote equitable outcomes despite the disparities students face as a result of the pandemic. The NSLB has fast-tracked the use of analytics and student narratives to transform the way we support students and enhance student success by effecting behavioural change that promotes student and institutional agency. NSLB has been an exercise of shared efforts to cultivate effective learning, teaching, and support that has exemplified the UFS’ organisational growth-mindedness. Numbers and words tell a better story – this has helped us become an agile, focused, and responsive institution.”

Keep moving forward

This approach has resulted in 99,95% of students participating in the first semester. The 0,05% (or 204) students who were not able to participate are being supported to continue their studies successfully. 

The success of the UFS’ approach is not only borne out by quantitative evidence, but also by qualitative feedback, such as the following quote sent to an academic adviser on 24 August:

“Thank you so much (adviser’s name); if it wasn't for you, I would have dropped out, deregistered or even committed suicide during this pandemic. I want to say that I have passed all my modules with distinctions, all thanks to you. After all the difficulty of learning I have experienced during this period. Please continue your great work to others (you were truly meant for this job) and God bless you.”

There are hundreds more testimonials like these, which testify to the inspiring efforts of students and staff at the UFS to finish the academic year successfully with very low risk. Some of these testimonials have been captured in the CTL publication, Khothatsa, which means ‘to inspire or uplift’.

Fight against Ebola virus requires more research
2014-10-22

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.
