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.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
