Maths Science and Technology Read More — 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.

Research into surrogate milk important to wildlife conservation

Research is being done at the University of the Free State (UFS) to analyse and synthetically imitate the unique milk of various wildlife species. This research is not only of scientific value, but also serves the conservation of South Africa’s wildlife species. At the forefront of this research is Prof Garry Osthoff from the Department of Microbial, Biochemical and Food Biotechnology.

Orphaned rhino calf pulled through with surrogate milk
“There is still a lot of research to be done. Naturally the research is of scientific importance, but with surrogate milk having the same composition as the mother’s milk of a specific species, orphaned calves or cubs of that species could be pulled through during a difficult time of weaning. Bearing in mind that exotic animals fetch thousands and even millions of rands at auctions, it goes without saying a game farmer will do everything possible to provide only the best nourishment to such an orphaned animal. In such a case, synthetically-manufactured milk would be the right choice,” says Prof Osthoff.

The fruits of his research were recently demonstrated in Germany when a rhino calf was left orphaned in the Leipzig Zoo. Prof Osthoff’s article: “Milk composition of a free-ranging white rhinoceros during late lactation” was used as a directive for applying surrogate milk for horse foals (which is already commercially available), since the composition of horse and rhino milk largely corresponds. The surrogate milk was used with great success and the rhino calf is flourishing. He mentions that such an orphan is often given the wrong nourishment with the best intentions, resulting in the starvation of the animal despite the amount of cow’s milk it devours.

Milk formula for baby elephants in the pipeline
With baby elephants left orphaned due to the increase in elephant poaching for their ivory, several attempts have been made to create a milk formula in order to feed these elephants. To date, many elephants have died in captivity from side effects such as diarrhoea as a result of the surrogate formula which they were fed.

Prof Osthoff recently received a consignment of frozen milk which he, together with researchers from Zimbabwe, will use to work on a milk formula for elephants. They are studying the milk in a full lactation period of two years. During lactation, the composition of the milk changes to such an extent that a single surrogate formula will not be sufficient. Four different formulas should probably be designed.

Prof Osthoff says that of the different species he has researched, elephants are the most interesting and deviate most from the known species.

Although his research to develop surrogate milk is adding much value to the wildlife industry, and although he finds this part of his work very exciting, his research focus is on food science and nutrition. “What is currently authentic in milk research is the study of the fat globules with content, the structure and composition of the casein micelle, and the prebiotic sugars. The knowledge which is gained helps to improve the processing, development of new food products, and development of food products for health purposes,” says Prof Osthoff.
