Prof Albert Weideman has designed language tests for South African institutions as well as universities in Namibia, Vietnam, Singapore, the Netherlands, and Australia

Prof Albert Weideman became involved in language testing in the 1980s and almost 40 years later, the South African Association for Language Teaching (SAALT) has now honoured him with a Lifetime Achievement Award for “his contribution to research and practice in applied linguistics, test design, and curriculum development in academic literacy”.

“It’s a wonderful honour to be recognised in one’s field in this way and I am humbled by the many congratulatory messages I have received from as far afield as the Netherlands, the US and Australia,” says Prof Weideman, senior research fellow in the Department of South African Sign Language and Deaf Studies at the University of the Free State (UFS). 

“I wish to dedicate it to the many dozens of MA students I have had, as well as to the many talented PhD students I have supervised,” he said upon receiving the award at the SAALT conference which was held at the University of Pretoria recently. 

Pioneer in the field of language assessment 

“His creative designs have enhanced the quality of academic literacy tests in South Africa,” says Prof Theodorus du Plessis, head of the Department of South African Language and Deaf Studies. The language courses which Prof Weideman has developed have been used at beginner, intermediate and advanced level, as well as for introducing teachers to innovations in language teaching.

During his career Prof Weideman has witnessed an interesting change in the assessment of language: “The focus of language testing has shifted from testing the so-called ‘skills’ of reading, writing, listening and speaking, to measuring communicative ability,” he says. 

He is very excited about the impact of the Fourth Industrial Revolution on language teaching, specifically when it comes to “computer adaptive language testing, and language-course delivery in a multiplicity of new media.”

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.
