Matric learners hone maths skills at Kovsies

MEC for Education, Dr Tate Makgoe, presents an award to Khesa Maphakiso from Beacon High School at the ceremony.

Projections indicate that by 2020 about 80% of all jobs will require some level of competency in Science, Technology, Engineering and Mathematics (STEM). Also, given the rising unemployment rate and the subsequent demand for entrepreneurial skills in the past few years, STEM education has become a priority for South Africa.

A step in the right direction

Equipping young people to be efficient in the world of work and business is a major driver behind the country’s education system. The MEC for Education in the Free State reiterated the importance of STEM subjects. Dr Tate Makgoe addressed about 200 top-performing Grade 12 learners from quintile 1-3 schools in the province who were attending the South African Institute for Chartered Accountants (SAICA) maths camp.

Making mathematics fashionable

The week-long camp recently closed with an awards ceremony which was held on the Bloemfontein Campus of the University of the Free State (UFS). Nine of the creams of the crop of matric learners were honoured for their achievements in mathematics, physical science, and accounting.

Zinhle Gumbi, from Morena Mokopela Secondary School, one of the three Mathematics Top Achiever award recipients has become more determined to choose a maths-related profession. “I have told myself that any career I follow must include maths. Dr Tate Makgoe said we must prove to people that the black child can do it.”

Emerging as one of the Accounting Top Achievers was Albert Ramatsekane from Tsoseletso Secondary School who intends to pursue a Chartered Accountant (CA) qualification. “The camp has boosted my confidence. Now I can choose the CA stream without thinking twice.”

Sowing the seed and reaping the fruits

Accounting lecturer Mojalefa Mosala was satisfied with the results of the camp. “I am happy to see many familiar faces in my classes who have attended previous camps. It means we’re doing something right.”

Mosala, a former assistant camp organiser, has confidence in the project as it “affords a rare opportunity to learners who have not been exposed to information, the higher learning environment, study skills and motivational figures to experience all of these”.
Kovsies prides itself in partnering with industry stakeholders to build the future of the country, one maths camp at a time.

UFS involved in project to light up the townships

2006-06-06

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens. The red, green and blue spots on the television screens originate from these kinds of phosphor materials. “At that stage plasma television screens were only a dream. Today it is sold everywhere,” said Prof Swart.

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material. We also started to concentrate on the effectiveness of nano phosphors. In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre. These particles can provide light as soon as they are illuminated with, for instance, sunlight. The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials. Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project. The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited. “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years. “During this time we want to determine how the effectiveness of the phosphors can be increased. Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
