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’.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
