Dr Bernard
Dr Eleanor Bernard heads the Centre for Teaching and Learning on the Qwaqwa Campus.

“I realised that our students are not regularly exposed to and immersed in an English first language environment. So, for two years, I created control groups and tested how to implement a film club to support their language learning as well as engage them. In the end, I created a framework that university language teachers can use, with very specific guidelines as to how to make it successful.”

For her PhD study in Higher Education Studies, Dr Eleanor Bernard created a play on traditional learning by implementing a film club as a way of enhancing the basic interpersonal communicative and English literacy skills of non-native speakers on the Qwaqwa Campus. Dr Bernard is the Assistant Director of the Centre for Teaching and Learning on the Qwaqwa Campus. She will be graduating with her PhD in Higher Education Studies during the December 2021 graduations. The title of her study is: Implementing a film club to enhance English second-language students’ basic interpersonal communicative and basic English literacy skills.

Building on her passion for language learning and acquisition, Dr Bernard wanted her study to be a fun and interesting way of enhancing the already existing General English language module by creating a space for exposure and social interaction. She did this by forming student groups that would regularly watch films and opened spaces for engagement as a way of focusing on the language development of the students.

“The highlight for me was sitting in a university lecture venue, while watching Tsotsi or Pitch Perfect with students, and seeing them interacting, laughing, and enjoying a usually very serious space. Also, the wonderful discussions they shared on Blackboard around elements such as lobola, or stereotypes. Lastly, seeing how by the end of the year, they would walk into my office and interact with me more confidently in English,” she said.

Language studies has been a part of her academic journey from her Honours qualification. She has an MA degree in Language Studies from the UFS. She said working on the Qwaqwa Campus with language and literacy modules, she loved the process of watching students blossom as they gained more confidence in using the English language. “I especially love receiving a student at the beginning of the year, who you can see struggling and almost battling through the content and the skills. And then to see the change by the end of the year, and how their confidence increased.”

‘No learning can take place without engaging students’
She said she hoped faculties would also see the value of focusing on the language development of students as a baseline for academic literacy skills development.

“No learning can take place without engaging students, and there are so many guidelines and practical ways to ensure this engagement, including in language learning. Student success is not just about performance or final marks, but also about students completing a year where they have interacted with others and learned to care for them, where they have been changed to want to impact societies and communities, and where they have acquired skills that they will use when they enter the world of work.”

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.
