Prof Liezel Nel, who received the 2020 Excellence in Learning and Teaching Award in the category Research in Teaching and Learning, says this recognition of her work is undoubtedly an inspiration to continue her research with even more vigour and enthusiasm.

Prof Liezel Nel, Adjunct Professor in the Department of Computer Science and Informatics at the University of the Free State (UFS), was announced as winner in the category Research in Teaching and Learning at the 2020 UFS Excellence in Learning and Teaching Awards, hosted by the Centre for Teaching and Learning in September this year.

Prof Nel, who is passionate about the Computer Science discipline due to its ever-changing nature, says she not only constantly revises the subject material, but also the way in which she presents it to students. “In order to be an effective facilitator, I adjust my teaching and learning strategies based on the needs of my students and their pace and depth of understanding,” she says.

As an adjunct professor, she currently teaches Web Development and Internet Programming modules on both undergraduate and postgraduate level. Prof Nel also supervises master's and PhD projects in the field of Computer Science Education. 

She believes in a research-informed way of teaching that is sensitive to the needs of individual students in a diverse educational context. Prof Nel is constantly investigating innovative ways in which the teaching and learning experiences of Computer Science students can be enhanced. “My teaching philosophy is geared towards the empowerment of my students in order for them to take control of their own learning experiences,” she adds.

Best teaching experience

She is in the position of working with students who are entering higher education for the first time and is of the opinion that especially first-year students need to be exposed to the best possible teaching experience.

“My students and I work together to overcome many of the unique challenges they are experiencing in order to better prepare them on an academic and a personal level for the successful completion of their higher education journey and for a successful career in Computer Science,” she says.

Besides the role that Prof Nel is playing in preparing first-year students, she also participates in the development of postgraduate students. “By involving all my postgraduate students in teaching and learning-related projects, I believe that I am playing a valuable role in shaping a new generation of teaching and learning scholars,” declares Prof Nel.

Continuous excellence

Her work to enhance the learning experiences of her students has received both local and national recognition. Since 2009, she has received numerous awards, including the UFS prestige award for Excellence in e-learning, the UFS prestige award for Excellence in Teaching; and the UFS Vice-Chancellor’s award for Scholarship of Teaching and Learning. Prof Nel also received the National Excellence in Teaching and Learning award from the Higher Education Learning and Teaching Association of Southern Africa and the Council for Higher Education (CHE).

Prof Tredoux turns theories regarding the formation of metals on its head

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.
