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’.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
