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.”

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
