Enhancing students’ linguistic abilities
Language teaching professionals from Southern Africa attended a two-day symposium on foreign language acquisition practice on the UFS Bloemfontein Campus.

Language teaching professionals from across Southern Africa recently gathered at the University of the Free State (UFS) to discuss the need for benchmarking and standardising teaching and assessment practices. 

With the aim of empowering lecturers and researchers responsible for language acquisition and delivering competent students to ensure their employability globally, the educators addressed the challenges of language acquisition in the region. It was the first time that educators from different language disciplines, including Dutch, German, French, Afrikaans, isiZulu, Sesotho, and Sign Language, met to discuss standardisation and best practices in teaching and assessment.

The symposium, which was hosted on the Bloemfontein Campus on 8 and 9 June 2023, brought together educators from the UFS, North-West University, University of Cape Town, University of the Western Cape, University of KwaZulu-Natal, University of Pretoria, Rhodes University, University of South Africa, Stellenbosch University, University of the Witwatersrand, University of Limpopo, and Sol Plaatje University. They were joined by participants from the University of Namibia and the National University of Lesotho, providing a regional perspective. 

Standardising language acquisition in Southern Africa 

Prof Angelique van Niekerk, Head of the Department of Afrikaans and Dutch, German and French, says the meeting marked a movement towards delivering competent students in order to increase their employability in languages such as Dutch, German, French, Afrikaans, isiZulu, Sesotho, and Sign Language. 

“It is probably the first time that the different language disciplines and colleagues from disciplines involved in language acquisition in Southern Africa have met to discuss the need for benchmarking and standardising.” 

“The symposium was not on multilingualism per se, but as language scholars, we support multilingualism. Social cohesion is affected positively if people and their culture and language are accepted and thus used.”

Talking about the need for a reference framework for benchmarking languages, Dr Michelle Joubert, Subject Specialist in the UFS Centre for Teaching and Learning, told delegates in her keynote address that a coordinated system provides a basis for the mutual recognition of language qualifications. 

“Our aim is to develop a framework of standards for indigenous and foreign languages to reflect the political and social realities of a multilingual and multicultural South Africa, which aims to form a single South African education, employment, and residential space for its citizens.”

In another keynote address, Dr Carina Grobler, Subject Chair and Lecturer in French at the North-West University, highlighted effective assessment tools to enhance students’ ability to learn additional languages. 

Prof Van Niekerk says many new initiatives, such as the sharing of resources on centralised platforms, were some of the gains following the symposium; a follow-up event is planned for 2024.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
