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.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
