Prof Liezel Nel, who received the 2020 Excellence in Learning and Teaching Award in the category Research in Teaching and Learning, says this recognition of her work is undoubtedly an inspiration to continue her research with even more vigour and enthusiasm.

Prof Liezel Nel, Adjunct Professor in the Department of Computer Science and Informatics at the University of the Free State (UFS), was announced as winner in the category Research in Teaching and Learning at the 2020 UFS Excellence in Learning and Teaching Awards, hosted by the Centre for Teaching and Learning in September this year.

Prof Nel, who is passionate about the Computer Science discipline due to its ever-changing nature, says she not only constantly revises the subject material, but also the way in which she presents it to students. “In order to be an effective facilitator, I adjust my teaching and learning strategies based on the needs of my students and their pace and depth of understanding,” she says.

As an adjunct professor, she currently teaches Web Development and Internet Programming modules on both undergraduate and postgraduate level. Prof Nel also supervises master's and PhD projects in the field of Computer Science Education. 

She believes in a research-informed way of teaching that is sensitive to the needs of individual students in a diverse educational context. Prof Nel is constantly investigating innovative ways in which the teaching and learning experiences of Computer Science students can be enhanced. “My teaching philosophy is geared towards the empowerment of my students in order for them to take control of their own learning experiences,” she adds.

Best teaching experience

She is in the position of working with students who are entering higher education for the first time and is of the opinion that especially first-year students need to be exposed to the best possible teaching experience.

“My students and I work together to overcome many of the unique challenges they are experiencing in order to better prepare them on an academic and a personal level for the successful completion of their higher education journey and for a successful career in Computer Science,” she says.

Besides the role that Prof Nel is playing in preparing first-year students, she also participates in the development of postgraduate students. “By involving all my postgraduate students in teaching and learning-related projects, I believe that I am playing a valuable role in shaping a new generation of teaching and learning scholars,” declares Prof Nel.

Continuous excellence

Her work to enhance the learning experiences of her students has received both local and national recognition. Since 2009, she has received numerous awards, including the UFS prestige award for Excellence in e-learning, the UFS prestige award for Excellence in Teaching; and the UFS Vice-Chancellor’s award for Scholarship of Teaching and Learning. Prof Nel also received the National Excellence in Teaching and Learning award from the Higher Education Learning and Teaching Association of Southern Africa and the Council for Higher Education (CHE).

Producers to save thousands with routine marketing strategies, says UFS researcher

Using derivative markets as a marketing strategy can be complicated for farmers. The producers tend to use high risk strategies which include the selling of the crop on the cash market after harvest; whilst the high market risks require innovative strategies including the use of futures and options as traded on the South African Futures Exchange (SAFEX).

Using these innovative strategies are mostly due to a lack of interest and knowledge of the market. The purpose of the research conducted by Dr Dirk Strydom and Manfred Venter from the Department of Agricultural Economics at the University of the Free State (UFS) is to examine whether the adoption of a basic routine strategy is better than adopting no strategy at all.

The research illustrates that by using a Stochastic Efficiency with Respect to a Function (SERF) and Cumulative Distribution Function (CDF) that the use of five basic routine marketing strategies can be more rewarding. These basic strategies are:
• Put (plant time)
• Twelve-segment pricing
• Three-segment pricing
• Put (pollination)(Critical Moment in production/marketing process), and
• Pricing during pollination phase.

These strategies can be adopted by farmers without an in-depth understanding of the market and market-signals. Farmers can save as much as R1.6 million per year on a 2000ha farm with an average yield.

The results obtained from the research illustrate that each strategy is different for each crop. Very important is that the hedging strategies are better than no hedging strategy at all.

This research can also be applicable to the procurement side of the supply chain.

Maize milling firms use complex procurement strategies to procure their raw materials, or sometimes no strategy at all. In this research, basic routine price hedging strategies were analysed as part of the procurement of white maize over a ten-year period ranging from 2002–2012. Part of the pricing strategies used to procure white maize over the period of ten years were a call and min/max strategy. These strategies were compared to the baseline spot market. The data was obtained from the Johannesburg Stock Exchange’s Agricultural Products Division better known as SAFEX.

The results obtained from the research prove that by using basic routine price-hedging strategies to procure white maize, it is more beneficial to do so than by procuring from the spot market (a difference of more than R100 mil).

Thus, it can be concluded that it is not always necessary to use a complex method of sourcing white maize through SAFEX, to be efficient. By implementing a basic routine price hedging strategy year on year it can be better than procuring from the spot market.
