Mineral named after UFS professor
Tredouxite (white) intergrown with bottinoite (light grey), a complex hydrous alteration product. The large host minerals are nickel-rich silicate (grey), maybe willemseite, and the spinel trevorite (dark grey).

More than five thousand minerals have been certified by the International Mineralogical Association(IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classificationwebsite, the Mineralogical Magazine and the European Journal of Mineralogy.

UFS awarded tenders worth R22,5 million for Maths and Science teacher-training
2010-03-17

The Centre for Education Development (CED) at the University of the Free State (UFS) has received tenders worth about R22,5 million over the past two years from four provinces to train Mathematics and Science teachers from underperforming schools.

The CED has received tenders from the following provincial departments of education: Free State, Northern Cape, North West and Mpumalanga.

“The centre has a good reputation for the training of teachers in these disciplines and has been involved with the upgrading of Maths and Science teachers for at least 15 years,” said Prof. Daniella Coetzee, Director of the CED.

It is currently busy with the training of North West teachers after being awarded a R13,5 million tender by the Province as part of its quest to improve pass rates in Mathematics and Natural and Physical Sciences in underperforming schools.

“The tender is for the upgrading of the knowledge and methodology of teachers for Mathematics and Natural and Physical Science, as well as the upgrading of the knowledge of subject specialists in the North West Province,” said Prof. Coetzee.

For this project the centre trains 1 000 teachers and 90 subject specialists from underperforming schools over a period of three years.

The programme commenced in February this year with a baseline assessment of the teachers to determine knowledge and methodology gaps upon which to focus in the training.

“After the programme has been completed we will also do a post-assessment to see if there had been progress,” she said.

The training is offered only on Saturdays at Vryburg, Klerksdorp, Makapanstad, Brits and Zeerust and is presented by lecturers from the CED as well as selected and trained tutors from the North West province.

“We have successfully completed another Maths, Science and Technology project for the North West Department of Education. We have also completed similar projects for the Northern Cape and one for the Free State Department of Education,” she said.

These completed projects entailed formal qualifications (Advanced Certificate in Education) in Maths, Science and Technology and were worth in excess of R5 million.

The CED has just been recently awarded yet another tender in excess of R4 million over a period of two years by the Mpumalanga Department of Education.

Prof. Coetzee had the following to say about the CED being the preferred choice of these provincial Departments of Education: “It has to do with the fact that the CED has been performing well with the upgrading of teachers. It has proven itself as a leader in the in-service training of Maths and Science teachers in South Africa.”
