The Economics and Management Sciences (EMS) Faculty at the University of the Free State (UFS) recently inaugurated its first Broadening Curricular Debate series, a concept conceived by the Dean of the Faculty, Prof Phillipe Burger. The inaugural debate, held on 22 November 2023 in the Equitas Senate Hall on the UFS Bloemfontein Campus, marked the beginning of a series designed to facilitate discussions among academics on crucial higher education matters.  Annari Muller, Chairperson of the Learning, Teaching and Digitisation Committee (LTDC), expressed the series’ purpose: “We organised this debate series to provide a platform for academics to discuss vital higher education matters. These sessions aim to stimulate critical conversations that empower UFS staff to enrich our curricula, enhance teaching practices, and shape broader educational strategies.’’ 

The motion presented to the house was, ‘The rapid integration of Artificial Intelligence in higher education perpetuates educational inequalities, widens the digital divide, and diminishes the value of personal instruction. The debate followed the structure of Intelligence Squared debates, with two teams comprising UFS staff from diverse departments, including the Department of Business Management, Department of English, Department of Public Management and the Department of Mathematical Statistics and Actuarial Science.

Naquita Fernandes, the Master of the House for the debate, emphasised the deliberate inclusion of members from diverse fields to infuse varied perspectives into the debate. “We believed that this diverse amalgamation of expertise would offer multifaceted insights, ensuring a holistic exploration of the subject matter. The debate structure was meticulously designed to encourage engaging discussions rather than formal academic presentations, allowing for a robust exchange of ideas.’’

The audience had the opportunity to vote on their stance before and after the debate, determining the winning team based on their ability to sway the audience with compelling arguments. The winning team, composed of Dr Hilary Bama (Senior Lecturer in the Department of Business Management), Dr Martin Rossouw (Senior Lecturer in Film and Visual Media), and Dr Rick De Villiers (Senior Lecturer in the English Department), successfully argued against the motion. 

The proposition team highlighted the existing gap between those with access to digital technologies and those without, advocating for a gradual and considered approach to AI integration in higher education. In contrast, the opposition team underscored the value of personal instruction in the face of AI, emphasising AI’s potential to provide constructive and effective feedback,  contribute to adaptive learning platforms, and accommodate unique learning styles and preferences. 

Following the debate, the audience was addressed by a team from Carnegie Math Pathways, providing insights into generative AI tools. Fernandes described the event as a proactive step in shaping the UFS academic landscape, moving away from reactive responses and exploring critical topics and strategies that could influence future policies and practices.

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.
