Two lecturers in the Department of Computer Science and Informatics at the University of the Free State (UFS) authored and presented a paper that received the best paper award at this year’s 50th Annual Conference of the Southern African Computer Lecturers’ Association (SACLA). 

SACLA is an association for academics teaching Computer Science, Information Systems, and Information Technology subjects at universities and other higher education institutions in Southern Africa. The Academy of Computer Science and Software Engineering at the University of Johannesburg hosted the conference.

Dr Pakiso Khomokhoana, Lecturer in the Department of Computer Science and Informatics, presented the paper titled Mapping the problem-solving strategies of novice programmers to Polya's framework: SWOT analysis as a bottleneck identification tool. He chose this topic because he was concerned that students (especially novices) are always encountering challenges when it comes to understanding source code and working with related problems.

Prof Liezel Nel, Associate Professor in the Department of Computer Science and Informatics, co-authored the paper with Dr Khomokhoana.

“When the time came to announce the best paper, my heart was panting, and I was thrilled to hear elements of my paper mentioned in preparation for the final announcement,” says Dr Khomokhoana, who reckons that the amount of work one puts into a paper is equivalent to the yield you receive in return.

He is convinced that one should feel the ‘pinch’ for whatever you do in life. Those who are studying can relate to nights spent toiling, headaches, and stressed muscles, with the pain only going away after reaching your goal. “One has to work hard in order to succeed in life,” he states.

He says that being recognised for this paper not only means that he can produce more acceptable research in the future; with the feedback received from reviewers, he can help other upcoming researchers by imparting to them the research skills he obtained over the years.

The UFS also presented a second paper at the conference. Mokotsolane Mase, Lecturer from the same department on the UFS Qwaqwa Campus, presented a paper co-authored by Prof Nel as well, titled: Common code writing errors made by novice programmers: Implications for the teaching of Introductory Programming.

Continuous excellence

The SACLA programme committee is committed to keeping papers earmarked for journal publication to a very high standard. “Since only the top papers are earmarked for journal publication, it was a great achievement to have both papers selected for inclusion in the 2021 publication,” says Prof Nel. 

However, the highlight of the conference for her was when the paper she co-authored with Dr Khomokhoana was recognised as the best paper. 

“What makes this achievement even more special, is that it is the second time in three years that Dr Khomokhoana and I have received this award (2019 and 2021). This is also the third time (since the inception of the ‘best paper award’ in 2014) that I have been the co-author of the best paper.”

“Being recognised at this level for our research in the field of Computer Science Education (CSE) is testament to the quality and importance of the research being conducted within the CSE research group of the UFS Department of Computer Science and Informatics,” she says. 

The way forward

Prof Nel believes in the potential of the CSE research group, and her goal for the next five years is to continue to expand the CSE research group within the department. 

“What I love most about this type of research is that it requires a close integration of the lecturing and research roles of academics. As educational researchers, we must reflect critically on our current teaching and learning practices and consider ways in which we can ultimately provide our students with the best possible learning experiences that will adequately prepare them for the world of work. Mentoring young academics who are interested in this field of research, is one of my biggest passions. By sharing our research at conferences (such as SACLA) and through publication in international journals, we contribute to the scholarship of teaching and learning on a much broader scale,” she says.

Researcher takes home gold at international Famelab competition

Recently, University of the Free State (UFS) Centre for Environmental Management master’s student, Tshiamo Legoale, was announced the FameLab International champion at the Cheltenham Science Festival in the United Kingdom. She is probing methods to use wheat as a gold hyper-accumulator – or, as she puts it, “grow gold from wheat”. The young researcher made South Africa proud by winning both the audience’s and the judges’ vote.

Coming back home a hero
“Winning was a surprise to me, because all 31 contestants had wonderful research. They all had really good presentations. I’m very grateful for all the support that I received from home. Social media showed me a lot of love and support. When I felt unconfident, they gave me ‘likes’ and that boosted my confidence a bit,” said Legoale about her win.

As South Africa celebrates Youth Month in June, Tshiamo represents hope for thousands of young South Africans to overcome difficult circumstances and follow careers in science.

The human impact is crucial, because Legoale’s win is not only scientific. It is also social and political. As a young female scientist in South Africa, she represented one of three African countries making it to the finals of FameLab, which has grown to one of the largest science communication competitions internationally.

With this in mind, Legoale says it may, in the end, be necessary to balance the needs of communities with the desire to increase yield. “Are we looking to make a fortune or are we looking to put food on the table?” she asks. “These are all things we consider when we conduct such research.”

World-class research from Africa
In South Africa, an estimated 17.7 million tons of gold is wasted. “All this gold was mined out previously, but tiny amounts remain in the dumps,” Legoale explains.

Her research focuses on the uses of wheat as a gold hyper-accumulator, which essentially means wheat plants are used to harvest gold from mine dumps. Simply put, the wheat is planted in the dumps, where enzymes found in the roots react with the gold and the plant absorbs it. The gold is then absorbed by every part of the plant, except the seeds, which means the next harvest can be used for food if need be.

“South Africa's world-champion young scientist, Tshiamo, represents all that is good about this country – brilliant, bright, and set for a fine future. I'm so proud that British Council SA, together with our partners SAASTA and Jive Media Africa, can help her along the way. Huge congratulations to her from all of us – it is a big win for Africa on the world stage,” said Colm McGivern, British Council South Africa Country Director.

The research represents a win on multiple levels. First, there are the obvious potential socio-economic benefits: food production, job creation, and phytomining is more economical than other contemporary mining methods.

Then there is safety. It is a more environmentally friendly practice than methods like heap leaching, carbon-in-leach or carbon-in-pulp. It is also safer for miners themselves, who will not be exposed to dangerous chemicals like mercury, which has been responsible for a great deal of toxicity in mine dumps. And it is safer for those living in the surrounds.
