The #FeesMustFall student-led movement started in 2015 to protest against increasing student fees and to call for increased government funding of universities. At the end of 2016, the protests led to mass disruption of academic activities in higher-education institutions countrywide. Some universities, including the University of the Free State (UFS), suspended academic activities for extended periods which necessitated online and blended learning approaches (the combination of face-to-face and online learning) to complete the academic year. In most cases, these methods were unplanned and unstructured, and knowledge gaps in good blended learning practice were identified.

The Carnegie Corporation of New York funded a two-year research project in collaboration with the University of Pretoria, UFS, University of Cape Town and University of Johannesburg to investigate the use of blended learning at the end of 2016, during the campus disruptions, as well as how these respective institutions used blended learning in 2017.

The prohibitive cost of data in South Africa means few of our students have access to the internet off-campus. The most recent data on UFS student digital identity shows that only 21% have consistent, reliable access to the internet at home. This is a challenge not only for the UFS but for all universities in the country.

“For technology to be used in a way that contributes to learning and teaching, we needed to investigate what works well and what does not, considering our contextual challenges” says Anneri Meintjes from the Centre for Teaching and Learning, who was the principal researcher for the UFS on this project. In the first phase of the research, she wrote a case study on the UFS’ approach to blended learning during and after the protests in 2016. The findings of this phase of the research were presented at a national convening of higher-education institutions across South Africa.

In the second phase of the research, the four participating universities produced open educational resources on good, blended learning practice to share with universities countrywide. The UFS was responsible for the development of online assessment resources and general best-practice guidelines for the use of blended learning. Anneri says: “While we had laid solid foundations for the effective use of online assessment at the UFS prior to 2016 through the investment in online assessment software and staff development in online assessment design, we learnt many valuable lessons during that time. It provided momentum for the establishment of formal online assessment procedures and refinement of best-practice guidelines. This research project gave us an opportunity to share our work on a national platform.” The number of lecturers that use online assessment in their modules has grown considerably at the UFS since 2016. In 2016, 211 online assessments were completed on Questionmark (UFS online assessment programme) and in 2018, this number had grown to 743. Institutional Blackboard use data shows that at least one online assessment tool is used in 47% of all modules on Blackboard.

Resources developed by the other participating institutions include a self-evaluation app that academics can use to reflect on their existing blended learning practices, and an online utility that assists lectures and course designers to plan blended learning modules.

Anneri also coordinated the development of the national website, which was launched at the Flexible Futures conference hosted by the University of Pretoria on 9-10 September 2019. The website and resources were praised at the conference for being a timely response to a critical need in the higher education community in South Africa.

UFS researcher engineers metal surfaces

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
