Data, quality, and capacity building were among the main topics of discussion at the third annual Teaching and Learning Conference hosted by the Centre for Teaching and Learning at the University of the Free State (UFS).

Dr Engela van Staden, Vice-Rector: Academic, welcomed delegates on the first day of the conference. The three themes of the conference were quality, capacity and excellence. “These three constructs have never been more relevant in South African higher education than now,’ said Dr Van Staden. “The quality of education, globally, and specifically in SA, is being questioned. Both public and private sectors are demanding graduates that need to meet the challenges of the 21st Century.” 

The aim of the teaching and learning conference is to foster more collaboration between academics at the UFS. A total of 14 academics from across all seven faculties presented during the two-day conference. Dr Whitty Green from the Department of Higher Education and Training (DHET) delivered the keynote on the first day and Prof Corlia Janse van Vuuren delivered the second day keynote.

The inclusion of technology in the world of work and the use of data analytics are fundamentally confronting our learning and teaching place. “And I hope some of the issues will be addressed in the presentations,” Dr Van Staden said. 

Bringing down silos of research and teaching

Dr Green spoke about the Enacting the National Framework for Enhancing Academics as University Teachers. “Academics are teachers and researchers and they have to engage with the community. There are multiple roles and these roles intersect,” Dr Green said. In order to build capacity in the system it is important to understand the multiple natures of the roles and try to work with them. This is the reason why the teaching development grant and teaching grant have been pulled together to form the University Capacity Grant. “We are trying to break down the silos of research development and teaching development at universities,” he said.

Prof Janse van Vuuren, Head of the UFS School of Allied Health Professionals, delivered her keynote address on Quality, Capacity and Excellence: Dotting the Is and crossing the Ts in a changing, data-driven Higher Education Environment. She shared her story to establish a faculty-based operational framework for teaching and learning.

“I did not know how to bring all of the issues ranging from research, teaching and learning and student success into one framework,” said Prof Janse van Vuuren. She developed a faculty-based operational framework for teaching and learning for the Faculty of Economic and Management Sciences.

The third annual UFS Teaching and Learning Conference took place from 26 to 27 March 2019.

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.
