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.

Discovery in Scorpius constellation may signify clean energy for Earth

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
