Dr Mirriam Moleko, a lecturer in the Department of Mathematics, Natural Sciences, and Technology Education in the UFS Faculty of Education, participated in the National Research Foundation’s Black Academics Advancement Programme fellowship and got the opportunity to visit universities and schools in the USA for three weeks.

After completing the National Research Foundation’s Black Academics Advancement Programme (BAAP) fellowship, a lecturer from the University of the Free State (UFS) now wants to train more teachers on issues of access and inclusivity in different mathematics settings. She also wants to establish a centre for access and inclusivity to promote quality teaching that caters to a diverse learner population.

Dr Mirriam Moleko, a lecturer in the UFS’s Department of Mathematics, Natural Sciences, and Technology Education in the Faculty of Education, participated in the BAAP fellowship, an initiative of the National Research Foundation (NRF) and the FirstRand Foundation (FRF), from 2021 to 2022. She also got the opportunity to visit universities and schools in the USA for three weeks.

Supporting emerging academics

Dr Moleko says the BAAP is a prestigious NRF programme which supports well-structured research projects with achievable aims, sound methodologies, and demonstrated prudent use of funds. The programme supports emerging academics to ensure that they develop strong research skills, collaborate with prolific scholars in their fields, visit other universities abroad, give public lectures, and attend international conferences to establish an international footprint.

“The programme allows the candidates awarded the grant to focus on research for two years” she says. “I managed to run my teacher community research project successfully during this period. My goal as an academic and a researcher is to produce work that teachers can relate to and be able to apply in their profession. I have always aspired to empower teachers to be knowledgeable and resourceful”.

“Furthermore, my goal is to strive to partake in critical conversations that are taking place within the mathematics education field, and to contribute my skills and knowledge in addressing the existing challenges, thus being part of the solution. I believe the skills that I have gained on how to conduct quality research will assist me in achieving my goals,” she added.

Benefit from funding

During the period of her fellowship she learned about forming partnerships and collaborating with other scholars in her field, which she believes is an important skill to possess as a developing scholar.

Dr Moleko says the programme played a pivotal role in the attainment of numerous significant accomplishments in her professional career thus far. She also benefitted in terms of funding, which helped her undertake autonomous research and advanced training in her area of expertise, as well as facilitated engagement in collaborative research ventures with esteemed professionals and researchers, both domestically and abroad.

“The research leave that I got enabled me to successfully conceptualise, strategise, and implement a research endeavour that yielded a more profound comprehension of the research gap that I had identified within the teacher community, thus culminating in multiple publications in esteemed periodicals.

“The NRF-BAAP funding also enabled me to undertake training, thereby refining my skill set and augmenting my comprehension of intricate principles. The experience proved to be a crucial factor in my vocational growth and bolstered my aptitude for scholarly inquiry. It also afforded me the chance to engage in mentoring endeavours for fledgling researchers.”

Transformation of the Professoriate Mentoring Programme

Dr Moleko, who is part of the UFS Transformation of the Professoriate Mentoring Programme, says this programme is an excellent initiative which is aimed at preparing young academics for future promotions and offering them skills to be competitive. The programme’s goals include building strong academics who will follow in the footsteps of the university’s current leaders.

She says the programme is critical in supporting young academics by connecting them with seasoned mentors and scholars from various fields of study. It is essential for young academics in terms of maximising their learning, expanding their network, and gaining opportunities to help facilitate their growth.

“I see the programme as a catalyst for change necessary for the university to realise the desired results,” Dr Moleko says.

During her visit to the USA she spent two weeks at Boston College and the University of Rhode Island, and also visited the Center for Applied and Specialised Technology, the Paul V. Sherlock Center on Disabilities (Sherlock Center), and the TechACCESS Center.

“The purpose of my visit was to establish networks and collaborate with prolific scholars outside South Africa on research engagements. Furthermore, the visit was intended for me to meet with my international mentors in person regarding research engagements.

“During my research visit, Prof Elizabeth Dalton from Rhode Island University and a UDL specialist, and I focused on several academic conversations and demonstrations of Universal Design for Learning (UDL) strategies and approaches, as well as the sharing of many online resources available to support the implementation of UDL in inclusive settings.”

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.
