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.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
