Academy for multilingualism
Dr Peet van Aardt, custodian of the new Academy for Multilingualism

The University of the Free State (UFS) established an Academy for Multilingualism at the beginning of 2021. The academy aims to promote Sesotho, isiZulu, and Afrikaans on institutional and social levels through various academic and community-based projects and initiatives. Multilingualism is conceptualised as a tool that leverages language richness to improve academic excellence and promote an inclusive institutional space.

The UFS Language Policy was approved by the Council in 2016, when English became the primary language of instruction at undergraduate and postgraduate levels on all three campuses. Through the policy, the university has pledged to enable a language-rich environment that is committed to multilingualism, with particular attention to English, Afrikaans, Sesotho, and isiZulu.  The academy serves as a vehicle to further imbed the implementation of the Language Policy.

Comprehension gaps
The Student Language Preference Survey completed in June 2020 indicated that many students have difficulty in understanding their lecturers in class due to language differences. “We also looked at multilingual models from places like South America, India, and South Africa in order to structure our approach,” says Dr Peet van Aardt, custodian of the academy. “Multilingualism has become a popular research field,” he explains, “and we hope to collaborate with universities that are implementing it successfully.” The academy is in the process of generating multilingual academic aids, not only to support learning, but also to create a more representative space on the university’s campuses.

The new look of academic languages
In close collaboration with the university’s Centre for Teaching and Learning, as well as the different language departments on the campuses, the Academy for Multilingualism will, among others, facilitate multilingual academic glossaries, abstract translations, voice-overs for lessons, and tutorials. “Our aim is to ingrain the academy in the university’s academic and social outlook through intra-institutional collaboration and becoming a leading institution on the world map of multilingualism,” Dr Van Aardt concludes.

Language links
The Academy for Multilingualism puts the UFS among the frontrunners of this approach.  “Language is a barrier to learning for many students,” Dr Van Aardt explains. “You just have to walk around on our campuses (or browse our social media platforms) to appreciate the many different languages that are used.” Dr Van Aardt believes that overcoming the language barrier to learning not only promotes knowledge gain but will also help students to develop an identity within their own language cultures.

Lithium-ion batteries research set to improve ordinary lives
2016-02-11

Description: Dr Lehlohonolo Koao  Tags: Dr Lehlohonolo Koao

Dr Koao is making a much-needed contribution in improving lives of ordinary people through his research on lithium-ion batteries.

The future of relevant and top-notch scientific research at the Qwaqwa Campus is in good hands. Dr Lehlohonolo Koao is one of the five members of the Vice-Chancellor’s Prestige Scholars Programme (PSP) on the Qwaqwa Campus.

The need to improve the efficiency of heating mechanisms in his immediate community in Qwaqwa, and the support he receives from the PSP, have become catalysts for his current research project on lithium-ion batteries. According to Dr Koao, the study will focus on producing batteries that last longer, store more energy, are cheaper to manufacture, and are environmentally friendly when being disposed of. These are key factors in solar energy.

‘’The majority of households in my neighbourhood have benefited from the government’s project of providing households with solar panels to help with lighting, cooking, and heating without worrying about the ever-increasing electricity costs,’’ said Dr Koao.

‘’Since my arrival in the area, I have realized that the heat absorption rate of the batteries used by solar panels is not enough. As a result, these batteries also lack enough power to sustain the supply throughout the day, especially on a cloudy day,’’ he said.

His research project focuses on improving the efficiency of lithium-ion batteries that are now commonly used in portable electronics, such as cell phones and laptops. This kind of battery is rapidly replacing the usual lead-acid batteries. Dr Koao’s determination to contribute towards a safer and more efficient heating absorption system has made him move away completely from his PhD study on lighting material.

‘’My previous study was on reducing the power usage on domestic and industrial lights as they use more electricity. This study, on the other hand, will enhance power retention in the batteries for improved daily life since cell phones, solar panels, and laptops, to mention only a few, are now a way of life,’’ he added.

Dr Koao is a Senior Lecturer in the Department of Physics, where he specializes in solid state materials.
