The University of the Free State (UFS) is playing a leading role in South Africa when it comes to implementing multilingualism in teaching and learning and has been one of the first tertiary institutions to establish an Academy for Multilingualism. 

The university has been working on multilingualism in various formats since 2016, when a new Language Policy was approved by the UFS Council. At a recent Universities of South Africa (USAf) colloquium, UFS representatives could share outcomes and lessons derived from the institution’s journey towards an inclusive multilingual environment.

The state of language diversity

A key starting point was to establish the state of language diversity at the UFS. A biographic survey among 17 000 students revealed that around 27% of them had Sesotho as home language, followed closely by isiZulu at around 25%. Around 13% cited isiXhosa, just under 9% Afrikaans, and 8.5% Setswana. A total of 70% of these students had English as their language of instruction in their final school year.

Translanguage Tutorials in different academic departments were among the projects introduced this year. During these tutorials students can discuss questions in any language but give feedback to the lecturer in English. This allows students to develop a better understanding of the work while enhancing their confidence to interact in English. 

“There are numerous scholars who have published on the value of shuttling between two languages – the phenomenon known as translanguaging – in order to promote a deeper and fluent understanding of the subject matter,” says Letsela Motaung, a researcher at the Centre for Teaching and Learning (CTL). “We follow a rigorous recruitment process to identify tutors among our senior and postgraduate students, who then get intensive training in peer-to-peer learning and collaboration before going on to design translanguaging activities that they put into practice.”

“We are creating a space where students can make sense of the work in their own language. In this way, we take away the stress that some students associate with language, creating a relaxed atmosphere that facilitates learning,” explains Prof Francois Strydom, Senior Director at CTL. 

Improving academic competency

Another initiative is to provide voice-overs in Sesotho, isiZulu and Afrikaans over module lessons in English. These are made available as video files on the Blackboard online learning platform, and has so far involved the Faculties of Humanities, Theology and Religion, and Natural and Agricultural Sciences. “The goal with creating these voiceovers is to improve, first and foremost, academic competency. It’s almost like providing students with an electronic tutor that’s always available,” says Dr Peet van Aardt, Custodian of the Academy for Multilingualism.

The feedback from lecturers and students on both these programmes has been overwhelmingly positive, and plans are in place for incorporating more modules next year. 

A programme also gaining momentum is the Initiative for Creative African Narratives (iCAN), where students contribute stories written in different languages to facilitate learning from and about one another. 

“We want to establish a scenario where languages are deeply respected, creating a rich environment for common understanding,” explains Prof Strydom.

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.
