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.

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
