“A quality higher-education learning experience is a transformative experience for both students and lecturers who develop their minds in criticality, as well as social and self-identity, in addition to other skills and competencies.” This was the message from Dr Patience Mukwambo at the launch of her recently published book – ‘Quality in Higher Education as a Tool for Human Development: Enhancing Teaching and Learning in Zimbabwe’.

The book is a product of her doctoral research and was launched by the office of the SARChI Chair in Higher Education and Human Development, where Dr Mukwambo is a full-time researcher and was introduced at an event held at the Bloemfontein campus of the University of the Free State (UFS) on 21 October 2019. 

Depressing higher-education system

Dr Mukwambo was joined in conversation by Prof Brian Raftopoulos, a Mellon Senior Research Mentor in the Centre for Humanities Research at University of the Western Cape. 

Both scholars testified to the concept of critical thinking, alluding to the depressing state of education in Zimbabwe due to limitations posed by a non-expanding economy and a repressive political space. 

Prof Raftopoulos told the audience the idea of critical thinking has a long genealogy in radical thought which has deepened its roots in modern-day society. 

“What you have seen through the introduction of STEM (Science, Technology, Engineering, and Mathematics), is the increasing idea of functionalising education for a work economy. More often than not, you will hear the state saying it is up to school-leavers to create their own jobs,” said Prof Raftopoulos. According to Dr Mukwambo, part of the challenge is that “critical thinking is omitted on purpose and therefore universities lack a moral compass to work from”.

“While the broader economy might be constraining there are opportunities to develop critical thinking in the classroom, although it might not be uniform across all universities,” said Dr Mukwambo.

Equipping graduates with critical-thinking skills contributes to a range of benefits, such as improved wellbeing, economic outcomes, political engagement, and human capital formation. Quality in teaching and learning is therefore indeed a step in the right direction, towards social justice.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
