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.

Getting out of the dark

Since 2008, the University of the Free State has been busy with the planning and implementation of projects to reduce the impact of load shedding. To date,  the cost of these projects has run to R6 million. They have been done primarily to ensure that the academic programme does not suffer damage as a result of the increasing interruptions in the power supply that are continuing this year.

The university’s greatest concern has been the provision of emergency power to the lecture halls and laboratories.

Thus far, 35 generators are servicing 55 buildings on the three campuses of the UFS. This includes 26 generators on the Bloemfontein Campus, eight on the Qwaqwa Campus in the Eastern Free State, and one generator on the South Campus in Bloemfontein. The generators are already in service, and are maintained in working order.

Since 2010, the university has also ensured that all newly-built academic buildings are equipped with emergency power supplies.

On the South Campus in Bloemfontein, the new lecture-hall building and the computer laboratory are equipped with emergency power, while the installation of emergency generators in other buildings is under way. The majority of the buildings on the Qwaqwa Campus in the Eastern Free State are equipped with emergency power supplies.

In the meantime, the UFS management has approved a further R11 million for the installation of additional generators on the three campuses. A further R1.5 million has also been approved for the purchase of two mobile generators.

To extend the work already done, the main task will be the installation of more generators on the Bloemfontein Campus to ensure that lecture halls with emergency power will be available for the centrally-arranged timetables, and to ensure that more of the critical laboratories will be provided with emergency power.

There are still  some important buildings and halls on the Bloemfontein Campus that must be supplied with emergency power. However, it is a costly process and must be brought into operation gradually. The further implementation of emergency power depends on the delivery of equipment. The university is also investigating alternative solutions for power provisioning, including solar power.

Generators with spare capacity are optimally deployed to satisfy the lower needs of the campus, including the Odeion, the ANNEX at Microbiology, the Stabilis ANNEX, the Agriculture Building, the UV-Sasol library, and the Francois Retief Building.

In addition, the UFS  is busy on all campuses, coupling area lighting, including

street lights and pedestrian walkways, to existing generators. Procedures for the operation of mechanical equipment, such as entrance gates, lifts, and so on, are currently being dealt with on all campuses. Continuous power sources for certain ICT equipment will be installed on all campuses to protect it against power surges.

Staff and students can also equip themselves with the necessary knowledge to manage load shedding in their specific areas of work and study. It is always helpful to know who to contact. The following list with guidelines and contact numbers has been compiled to assist you:

1. In an emergency, call Protection Services. This line will continue to operate, regardless of whether the power is on or off.
2. Avoid using lifts just before planned load shedding. Some lifts have emergency power packs which will bring the lift to the nearest floor and open the doors. If you still get stuck in a lift during a power outage, use your cellphone to call Protection Services. While you're waiting, stay calm and be patient.
3. If the access control systems in your building stop working after load shedding, contact Protection Services.
4. The students and staff members who are most at risk during load shedding are those in wheelchairs or with other mobility limitations. As far as possible, plan ahead to avoid being stuck on a floor or in a room that is difficult to access when load shedding is imminent. Please contact Protection Services if you need assistance.
5. During a fire, alarms WILL go off. Alarms are not power driven, but battery driven. For assistance, contact Protection Services.
6. The main UFS Switchboard (Bloemfontein Campus +27(0)51 401 9111 and Qwaqwa Campus +27(0)58 718 5000) will continue to operate during load shedding.

Contact details of Protection Services:

  • Bloemfontein Campus: +27(0)51 401 2634/2911
  • Qwaqwa Campus: +27(0)58 508 5460/5175
  • South Campus: +27(0)51 5051217

Communication and Brand Management will make information available on the UFS web, Facebook page, Twitter, Blackboard and the intranet. Get the load shedding schedule from Eskom’s webpage (http://loadshedding.eskom.co.za/). The Bloemfontein Campus falls in group 4 and the South Campus falls in group 2 in Centlec’s load shedding schedule.
