Dr Rouxan Fouché, Lecturer in the Department of Computer Science and Informatics at the University of the Free State (UFS), earned national recognition when he received both the Best Informatics Paper and the Overall Best Paper awards at the 54th Annual Conference of the Southern African Computer Lecturers’ Association (SACLA 2025). Held in Bloemfontein from 30 July to 1 August, the conference brought together leading voices in computer science education from across the region. Dr Fouché’s award-winning paper, Beyond Language Barriers: Programme-Specific Effects of English Medium Instruction in South African Computer Science Education, explores the nuanced impact of language on student learning in multilingual computer science classrooms.

“It was incredibly humbling and exciting to receive this recognition,” said Dr Fouché. “When they announced the Best Informatics Paper Award, I was already thrilled, but when they called my name again for the Overall Best Paper Award, I was genuinely shocked.”

The paper, which investigates how English-medium instruction affects students differently across different types of modules, stood out for its relevance to both educational policy and classroom practice in multilingual contexts. “As a researcher, you hope your work will make an impact,” Dr Fouché reflected, “but to have it recognised at this level by peers across the computer science and informatics community in Southern Africa was beyond my expectations.”

Representing the UFS at SACLA added another layer of significance. “Our university has such a rich tradition in computer science and informatics education,” said Dr Fouché. “The Free State context, with our incredibly diverse student population representing all 11 official languages, provides a unique lens for understanding multilingual education. I was proud to show how the UFS is leading research into practical solutions for South African higher education challenges.”

 

Rethinking language barriers in STEM education

The award-winning study stemmed from a broader investigation into student attrition in computer science. “Language barriers represent just one component of the various factors I'm studying that affect student success and retention,” explained Dr Fouché. “Like many educators in South Africa, I knew that a very low percentage of our Department of Computer Science and Informatics students are native English speakers, yet we teach everything in English.”

What the research uncovered was unexpected. “Students with language difficulties weren't struggling uniformly across all modules as we might expect,” Dr Fouché said. “Instead, there were dramatic differences depending on the type of content.” In particular, programming modules seemed to pose very little additional difficulty for students with language barriers, while business-related modules presented significant challenges.

“The most significant finding was that programming education appears to naturally transcend language barriers,” said Dr Fouché. “We found negligible differences in perceived difficulty between students with and without language difficulties in core programming modules – effect sizes of just 0.017 to 0.041, which is essentially no difference.” Surprisingly, students with language difficulties actually found mathematics and physics modules easier than their English-proficient peers, while business modules showed the opposite trend.

“These findings suggest that instead of treating all technical subjects the same, we need programme-specific support strategies,” he said. “Computer science education might offer a more equitable pathway to technical careers for our multilingual student population.”

Dr Fouché hopes the findings will inform more tailored teaching approaches: “We should emphasise visual representations, multiple symbolic systems, and hands-on applications that play to students' compensatory strengths for mathematics and physics. We need targeted interventions for business-related modules and additional support for the dual cognitive load of processing both technical and business terminology simultaneously.”

 

A research journey driven by equity

Dr Fouché’s academic journey spans human-computer interaction, digital inclusion, and educational equity. His doctoral work used a community-based action research approach to address the digital divide in marginalised communities. “The connection between these areas is really about equity and access,” he said. “Whether it's digital inclusion in marginalised communities or language barriers in technical education, I'm interested in understanding and addressing the systemic factors that prevent people from fully participating in our increasingly digital world.”

He credits mentors such as Prof Tanya Stott and Prof Liezel Nel for shaping his research path, and values collaboration with colleagues such as Dr Wynand Nel and Dr Pakiso Khomokhoana, among others. His advice to emerging researchers? “Embrace the South African context as a strength, not a limitation. Our linguistic diversity, postcolonial educational legacy, and unique challenges aren’t obstacles to overcome, but valuable perspectives that can contribute to global knowledge.”

Dr Fouché is now planning a longitudinal study to track students over time and explore how early advantages or disadvantages related to language shape long-term academic and career outcomes. His work continues to position the UFS as a leader in evidence-based, inclusive computer science education.

Studies to reveal correlation between terrain, energy use, and giraffe locomotion
2016-11-18



More than half of giraffes in captivity in Europe are afflicted by lameness. This high prevalence represents an important welfare issue, similar to other large zoo animals.

According to Dr Chris Basu, a veterinarian at the Royal Veterinary College in the UK, giraffes in captivity are often afflicted by overgrown hooves, laminitis and joint problems. Diagnosis and treatment is limited by our understanding of anatomy and function, more specifically the locomotion of these animals. Although the giraffe is such a well-known and iconic animal, relatively little has been studied about their locomotor behaviour.

Dr Basu recently visited South Africa to do fieldwork on the locomotion of giraffes as part of his PhD studies under the mentorship of world-renowned Professor of Evolutionary Biomechanics, Prof John Hutchinson. This project is a joint venture between Dr Basu and Dr Francois Deacon, researcher in the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research. 

Together Prof Hutchinson and Drs Deacon and Basu form a research group, working on studies about giraffe locomotion.

Wild giraffe population decrease by 40% in past decade

“Locomotion is one of the most common animal behaviours and comes with a significant daily energetic cost. Studying locomotion of wild animals aids us in making estimates of this energetic cost. Such estimates are useful in understanding how giraffes fit into ecosystems. Future conservation efforts will be influenced by knowledge of the energy demands in giraffes.

“Understanding aspects of giraffe locomotion also helps us to understand the relationships between anatomy, function and evolution. This is relevant to our basic understanding of the natural world, as well as to conservation and veterinary issues,” said Dr Deacon.

Locomotion study brings strategy for specialist foot care

On face value it seems as if foot disease pathologies are more common in zoo giraffes than in wild giraffes. “However, we need a good sample of data from both populations to prove this assumption,” said Dr Basu. 

This phenomenon is not well understood at the moment, but it’s thought that diet, substrate (e.g. concrete, straw, sand and grass) and genetics play a part in foot disease in giraffes. “Understanding how the feet are mechanically loaded during common activities (standing, walking, running) gives our research group ideas of where the highest strains occur, and later how these can be reduced through corrective foot trimming,” said Dr Basu.

Through the studies on giraffe locomotion, the research group plans to devise strategies for corrective foot trimming. At the moment, foot trimming is done with the best evidence available, which is extrapolation from closely related animals such as cattle. “But we know that giraffes’ specialist anatomy will likely demand specialist foot care,” Dr Basu said.

Studying giraffes in smaller versus larger spaces

The research group has begun to study the biomechanics of giraffe walking by looking at the kinematics (the movement) and the kinetics (the forces involved in movement) during walking strides. For this he studied adult giraffes at three zoological parks in the UK. 

However, due to the close proximity of fencing and buildings, it is not practical to study fast speeds in a zoo setting. 

A setting such as the Willem Pretorius Nature Reserve, near Ventersburg in the Free State, Kwaggafontein Nature Reserve, near Colesberg in the Karoo, and the Woodland Hills Wildlife Estate in Bloemfontein are all ideal for studying crucial aspects such as “faster than walking” speeds and gaits to measure key parameters (such as stride length, step frequency and stride duration). These studies are important to understand how giraffe form and function are adapted to their full range of locomotor behaviours. It also helps to comprehend the limits on athletic capacity in giraffes and how these compare to other animals. 

Drones open up unique opportunities for studying giraffes

The increasing availability of unmanned aerial vehicles (UAVs)/drones opens up unique opportunities for studying locomotion in animals like giraffes. Cameras mounted onto remotely controlled UAVs are a straightforward way to obtain high-quality video footage of giraffes while they run at different speeds.

“Using two UAVs, we have collected high definition slow motion video footage of galloping giraffes from three locations in the Free State. We have also collected detailed information about the terrain that the giraffes walked and ran across. From this we have created 3D maps of the ground. These maps will be used to examine the preferred terrain types for giraffes, and to see how different terrains affect their locomotion and energy use,” said Dr Deacon.

“The raw data (videos) will be digitised to obtain the stride parameters and limb angles of the animals. Later this will be combined with anatomical data and an estimation of limb forces to estimate the power output of the limbs and how that changes between different terrains,” said Dr Basu.
