At the 31st Annual Conference of SAARMSTE, were from the left: Prof Loyiso Jita, Dean of the UFS Faculty of Education; Prof Dr Susanne Prediger, plenary speaker, Prof Francis Petersen, UFS Rector and Vice-Chancellor; Dr Maria Tsakeni, Head of the UFS Department of Mathematics, Natural Science and Technology Education and Conference Chair; Dr Tulsi Morar, SAARMSTE President; and Prof Mogege Mosimege, Research Chair in Mathematics Education and Director of Initial Teacher Education at the UFS.

The University of the Free State (UFS) hosted the 31st Annual Conference of the Southern African Association for Research in Mathematics, Science and Technology Education (SAARMSTE) on its Bloemfontein Campus from 17 to 19 January 2023.

After two years of hosting the SAARMSTE conference virtually, it was presented as a hybrid conference for the first time. In attendance were delegates from the continent, the USA, India, Australia, and Europe.

The conference theme was: Intersecting Research, Policy and Practice for a Sustainable Praxis in Mathematics, Science and Technology Education: New possibilities and directions for the post-COVID-19 Pandemic Era.

 

Sharing best practices and discussing common challenges

SAARMSTE President, Dr Tulsi Morar from the Nelson Mandela University, believes that the conference provided fertile ground for delegates to share best practices, to discuss common challenges experienced during the pandemic, and to celebrate how these challenges were overcome. "It is only through our reliance and strength that we have succeeded, and because of our experiences, we can grow and innovate to be better prepared for any further challenges," he said.

Opening the event was Prof Francis Petersen, Rector and Vice-Chancellor of the UFS. He said the conference provided meaningful discussions for the challenges the world has to solve, stating that with challenges also come possibilities.

“We live in a time of significant change in the realm of technology, which has an impact on the world of work. Graduates will need to change their thinking in the world of work. They need to understand the future world of work,” Prof Petersen stated.

He also touched on curriculum reform, saying that a critical challenge for South Africa's education system is the decolonisation of the curriculum. What is being taught must make meaningful sense in our context. “The UFS has made significant progress in curriculum transformation since 2016,” he added.

With delegates as well as speakers from other countries present at the conference, Prof Petersen also talked about the UFS’ Global Citizens initiative. He said no country can operate in isolation. We need to learn from each other to move forward as a collective. “It is also vital to deliver global citizens,” he said.

“The importance of the SAARMSTE conference cannot be overemphasised in our current education landscape. We need sustainable relationships to be developed at conferences such as these in order to ask questions, think differently, and renew ourselves,” he concluded, stating that the role of humanities and social sciences in society is critical and that SAARMSTE can add value in this context.

 

Thinking indigenously about Technology education and its implementation

Contributing to robust discussions on Science, Technology, Engineering and Mathematics education, three keynote speakers shared their views during the three-day conference.

Prof Dr Susanne Prediger, Director of the newly established DZLM, the German National Centre for Mathematics Teacher Education, delivered the first keynote address of the conference. She talked about Fostering students’ understanding of procedures and underlying basic concepts: Design research for mathematics classrooms and teacher professional development in the post-pandemic era.

She said that although providing students with rich and deep mathematical learning opportunities is a common request in Mathematics education, many students are still only exposed to superficial learning. According to her, this was aggravated by the school closures during the pandemic and will continue in the post-pandemic era if Mathematics teachers are not sufficiently supported and prepared.

The second plenary was delivered by Prof Mishack T Gumbo from the University of South Africa. He is a Research Professor of Indigenous Technology Knowledge Systems Education in the Department of Science and Technology Education. The title of his talk was: A relook into Technology Education: Raising a transformational issue, where he focused on education, specifically the curriculum of Technology Education as a school subject.

The third plenary was delivered by Dr Gillian Roehrig from the University of Minnesota in the United States. Dr Roehrig is known for her research that explores issues of professional development for K-12 Science teachers, with a focus on the implementation of integrated STEM learning environments and the induction and mentoring of beginning secondary Science teachers.

Her paper, titled The Hows and Whys of Integrated STEM Education, explored the development of a conceptual and curricular framework for integrated STEM, and the benefits of using interdisciplinary approaches to address the policy goals of preparing students as STEM-literate citizens and for the future STEM workforce.

UFS involved in project to light up the townships
2006-06-06

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships   

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.   

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens.  The red, green and blue spots on the television screens originate from these kinds of phosphor materials.  “At that stage plasma television screens were only a dream.  Today it is sold everywhere,” said Prof Swart. 

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material.  We also started to concentrate on the effectiveness of nano phosphors.  In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre.  These particles can provide light as soon as they are illuminated with, for instance, sunlight.  The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials.  Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.   

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.  

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project.  The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited.  “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years.  “During this time we want to determine how the effectiveness of the phosphors can be increased.  Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
