S4F2024
The Science-for-the-Future (S4F) unit in the Faculty of Education hosted a summit on 13 September 2024. The event, which was held on the University of the Free State Bloemfontein Campus, was well attended by nearly 300 guests from across the country.

Teachers from across the country and representatives of nine other universities recently gathered at the University of the Free State (UFS) to celebrate the achievements of the S4F Teacher Professional Development programmes as well as the successful collaboration between the UFS and other universities in this regard.

The Science-for-the-Future (S4F) unit in the Faculty of Education hosted a summit in the Centenary Complex on the Bloemfontein Campus on 13 September 2024. The acting Vice-Chancellor and Principal of the UFS, Prof Anthea Rhoda, delivered the keynote address at the summit. Representatives from the South African National Roads Agency (SANRAL) – the official funder of the Science for the Future initiative – were also present, along with about 300 attendees, representing teachers, participating universities, representatives from the Department of Basic Education, and other stakeholders.

In her welcoming address, Prof Matseliso Mokhele Makgalwa, Vice-Dean of the Faculty of Education, said the event focuses, among others, on fostering collaboration and innovation across academic and professional communities. She later highlighted the fact that the project implementation period of three years makes provision for continued visits to the participating schools to sustain the continuity over time.

Dr Cobus van Breda, Programme Director of S4F and Project Manager of the Universities Collaboration initiative, elaborated on the rationale of the project as well as the collaboration with nine other universities. He stated, “We know from research that there are many factors that prevent learners, especially in rural areas in South Africa, from excelling in Mathematics and Science. These include subject content knowledge, lack of teaching resources at school and at home, language of learning and teaching that differs from home language, along with a lack of parental involvement, among others.” He said the project aims to address these rampant challenges by not only empowering teachers with the necessary teaching skills and content knowledge, but also providing classroom resources to benefit learners and adding a parental involvement component to the project. 

To scale the project benefits for the rest of the country, the UFS has partnered with nine other universities; collectively, more than one hundred thousand project participants (teachers, learners, and parents) could be impacted during 2024. The collaborating universities are Nelson Mandela University, the Walter Sisulu University, the University of Limpopo, the University of KwaZulu-Natal, the University of Mpumalanga, Sol Plaatje University, the University of Venda, Stellenbosch University, and Nort-West University.

Representatives from the Department of Basic Education and other institutions were also given the opportunity to highlight the impact of the initiative in their respective institutions. Maki Molale, Senior Education Specialist  from the Free State Department of Basic Education, reflected on the contribution of the project and said, “In the Department of Education we report on these key areas: teacher development, direct learner support, parental involvement, the utilisation of resources and partnerships … they are all addressed in this project.” She thanked the University of the Free State and the funder, SANRAL. Dr Glynnis Daries from Sol Plaatje University spoke on behalf of the collaborating universities and explained from an academic perspective to attendees how the project implementation strategy of S4F relates to Bronfenbrenner’s bioecological theory of human development and how the respective project components showcase the five levels of this theory.

During the keynote address, Prof Rhoda emphasised the importance of Mathematics skills, teaching children the capacity to solve problems and how it is extremely important to be analytical in one’s approach to resolving complexities and to work through problems in a methodical and logical manner. In the end, if one does this, no challenge is insurmountable. She commended the teachers present for fulfilling a vital task and pointed out the heavy responsibility on their shoulders. In this regard, she said, “As the UFS, and through the Science for the Future project, we are proud to support you in your work. The project is a vehicle through which we fulfil the central goals of the UFS, which are to impact the community in a positive way, and to instil a culture of excellence in a caring environment. We will continue to support you in your work and do all that we can to make your work more fulfilling and impactful – this is the promise of the UFS to our partners through this project.”

In acknowledging the contribution of the respective collaborating universities, Prof Rhoda emphasised that partnerships and collaborations are not easy to build, and most importantly, to maintain … “but what I’m hearing through these engagements today is that these partnerships are not just being maintained, they are expanded … the collaboration impacted the different institutions as well as, most importantly, the communities, close to and around them”. She alluded to the fact that universities’ roles are not just to retain and accept students, but universities have an important role in being the anchor within the society and communities in which they find themselves. According to her, the contribution of SANRAL and other project funders thus extends far beyond teachers’ professional development and community empowerment, it contributes towards assisting universities in engaged scholarship activities.

In reflecting on the parental involvement component of the programme, Themba Mhambi – Chairperson of the SANRAL Board – said that apart from being a maths and science project, and a project that is developmental, that is nation building, “… it becomes a kind of template for perhaps how our education system needs to be re-constructed … reclaiming the old times when parents and teachers worked together with the child in the centre”.

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.
