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.

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
