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.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
