Data, quality, and capacity building were among the main topics of discussion at the third annual Teaching and Learning Conference hosted by the Centre for Teaching and Learning at the University of the Free State (UFS).

Dr Engela van Staden, Vice-Rector: Academic, welcomed delegates on the first day of the conference. The three themes of the conference were quality, capacity and excellence. “These three constructs have never been more relevant in South African higher education than now,’ said Dr Van Staden. “The quality of education, globally, and specifically in SA, is being questioned. Both public and private sectors are demanding graduates that need to meet the challenges of the 21st Century.” 

The aim of the teaching and learning conference is to foster more collaboration between academics at the UFS. A total of 14 academics from across all seven faculties presented during the two-day conference. Dr Whitty Green from the Department of Higher Education and Training (DHET) delivered the keynote on the first day and Prof Corlia Janse van Vuuren delivered the second day keynote.

The inclusion of technology in the world of work and the use of data analytics are fundamentally confronting our learning and teaching place. “And I hope some of the issues will be addressed in the presentations,” Dr Van Staden said. 

Bringing down silos of research and teaching

Dr Green spoke about the Enacting the National Framework for Enhancing Academics as University Teachers. “Academics are teachers and researchers and they have to engage with the community. There are multiple roles and these roles intersect,” Dr Green said. In order to build capacity in the system it is important to understand the multiple natures of the roles and try to work with them. This is the reason why the teaching development grant and teaching grant have been pulled together to form the University Capacity Grant. “We are trying to break down the silos of research development and teaching development at universities,” he said.

Prof Janse van Vuuren, Head of the UFS School of Allied Health Professionals, delivered her keynote address on Quality, Capacity and Excellence: Dotting the Is and crossing the Ts in a changing, data-driven Higher Education Environment. She shared her story to establish a faculty-based operational framework for teaching and learning.

“I did not know how to bring all of the issues ranging from research, teaching and learning and student success into one framework,” said Prof Janse van Vuuren. She developed a faculty-based operational framework for teaching and learning for the Faculty of Economic and Management Sciences.

The third annual UFS Teaching and Learning Conference took place from 26 to 27 March 2019.

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.
