Technology and mentoring key in UFS approach to learner success
The University of the Free State has been changing the lives of high school learners through its Internet Broadcast Project.

The University of the Free State (UFS) has been changing the lives of high school learners through its Internet Broadcast Project (IBP). The project was established in 2011, with the vision of taking quality education to all learners across the Free State province, regardless of their socioeconomic backgrounds.  

The UFS IDEAS Lab, located on the UFS South Campus, is home to the IBP. Every day, the IBP transmits lessons to 83 schools spread across five districts in the Free State for learners in Grades 8 to 12. Learners also have electronic access to this material, which is presented for more than 15 school subjects. 

The benefits of technology

A collaboration with the university and the Free State Department of Education, the project includes support for subjects such as Mathematics, Physical Science, Life Science, Economics, Accounting, and Geography. The technology provided at each school allows learners to communicate with the presenter in the studio during a broadcast at no cost to the school or learner.

"The UFS is proud to be associated with the Department of Education and salutes it for the many initiatives in schools across the province, which contributed to outstanding matric results,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor. 

In 2017, Free State MEC for Education, Tate Makgoe, made special mention of the IBP for the role it played in contributing towards the best matric results in the Free State for the second consecutive year. Other former successes of the IBP include the announcement of the project as the winner of the 2015 Enterprise Video Award (EVA) in the category Video in Education Scholarship. This makes it two in a row, since the IBP also won an EVA in 2014 for Innovation in Pedagogy.

Motivated by dreams of something better

Makgoe said that part of the success of the province can be attributed to the project. Many of the top-performing schools had learners who participated in the IBP. In 2017, the Xhariep District, one of the districts forming part of the project, was named the top-performing district in the province, and second in the country. 

“Dreams and goals that you set for yourself are what keep you motivated, even if you are on the verge of giving up. Your dreams will motivate you to work harder and keep going,” says Lefu Matlala, a former IBP learner from Lefikeng Secondary School in Botshabelo. Lefu successfully used the IBP to support his learning and matriculated as one of the top five in the province in 2017. Through the help of the IBP and his teachers, Lefu scored 99% for Mathematics, 96% for Physical Sciences, and 85% for Geography. 

Social Responsibility Enterprises 

The Social Responsibility Enterprises (SRE) focuses on the mentoring of teachers in order to make a sustainable impact. A total of 78 schools in the Free State, Mpumalanga and the Eastern Cape benefit from this programme. SRE mentors assist school principals with school management, while teachers in Mathematics, Physical Science, Accounting, and English as a language of learning are assisted in mastering of curriculum content, pedagogy, and classroom management. The project has an annual budget of more than R15 million – all of which comes from sponsors outside the UFS.

Mentors visit schools and share knowledge, extra material, and technology to improve the standard of teaching. The change has been significant. Matric results, Mathematics pass rates, and Physical Science pass rates have improved dramatically in these schools. Another aspect is the identification of learners with potential (so-called first-generation students) to go to university. They are assisted through extra classes and in applying for tertiary education and bursaries.

Many of them (782) are currently studying at the UFS, and also receive mentorship at the university. HS van der Walt, Head of Social Responsibility Enterprises, says his team is proud to be part of the process of helping the Free State to become the No 1 province in the country again.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
