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.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
