From 21 to 23 November, more than 160 delegates gathered at the Golden Gate Highlands National Park in the Eastern Free State for the fourth biennial conference on Scholarship of Teaching and Learning (SOTL) in the South, dubbed SOTL 4 the South.

This year’s iteration was proudly hosted by the University of the Free State (UFS) and organised by Dr Jared McDonald, Chief of Staff in the Office of the Vice-Chancellor and Principal; Dr Eleanor Bernard, Assistant Director in the Centre for Teaching and Learning on the UFS Qwaqwa Campus; and Prof Zach Simpson, Editor-in-Chief of the SOTL in the South journal. Established and emerging scholars, as well as postgraduate students working in the field of teaching and learning from across disciplines in Southern Africa, came together to share ideas, debate perspectives, and learn from experiences related to the conference theme: Teaching and Learning for Sustainable Futures.

The programme included presentations on a wide variety of topics, such as the challenges and opportunities of artificial intelligence in higher education, academic literacy, student success, teaching and learning for sustainable development, curriculum design, and digital futures. The programme also included two keynote presentations by leading scholars in education for sustainability, Prof Heila Lotz-Sisitka, Distinguished Professor and SARChI Research Chair in Global Change and Social Learning Systems in the Environmental Learning Research Centre at Rhodes University, and Prof Kasturi Behari-Leak, Associate Professor of Higher Education Studies and Dean of the University of Cape Town’s Centre for Higher Education Development.

The organisers were delighted with the quality of the scholarship that was shared. “This conference has been 18 months in the making, and we are grateful to all the delegates for embracing, and engaging with, the conference’s theme. We are also appreciative to all the reviewers on the Scientific Review Committee who were generous with their time, reflections, and critiques in assisting us to deliver a compelling, impactful programme,” said Dr McDonald. Dr Bernard added that “the conference would not have been possible without the generous support of the University of the Free State’s Executive Management and Centre for Teaching and Learning, as well as the senior management of the Qwaqwa Campus, who have supported the conference from the time it was just an idea”.

Prof Zach Simpson expressed his gratitude to the UFS for its support and assistance. “The last in-person conference of SOTL in the South was in 2019, before the COVID-19 pandemic. It was wonderful to see so many scholars come together in a beautiful location to engage with a compelling and topical conference theme.” Selected papers have been invited to contribute to a special issue of SOTL in the South, edited by the organisers and due for publication in mid-2024.

SOTL is an informal ‘body’ that is not affiliated with any particular parent organisation or institution. Its aim is to advance scholarship in teaching and learning across the Global South – conceived of not just in geographic terms – but as concerned with questions of power, access, inequity, and marginalisation, even where these might be present in the Global ‘North’. Moreover, it aims to give voice to novice SOTL practitioners and to serve as a platform for academics, particularly novice academics, to contribute their scholarly work.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
