Our lives as we know it will never be the same again because of the Covid-19 pandemic. The education system, among other sectors, will be subjected to changes in the provisioning of teaching and learning. 

School disruptions are a familiar phenomenon in both basic and post-school education in South Africa. In recent years, South Africa has seen waves of student boycotts, disruptions, and shutdowns of universities and TVET colleges. Most disruptions lasted for a few days, while some went on for several weeks. One case in particular is that of Vuwani in Limpopo, where more than 50 schools were either vandalised or burned to ashes; nevertheless, the school year was recovered, and learners progressed to the next level. The main difference between the usual disruptions and the current situation lies in the enormity of the shutdown, given that it is clouded at a national level by unpredictable decisions made by the National Committee. 

Shortening school holidays
If the June exams were to be scrapped, the chief challenge would be the lost opportunity to evaluate and assess the extent to which the students have achieved the academic objectives stipulated for the subjects in the curriculum. June examinations for the other grades may not have a serious impact on the learner’s progress to the next class, as other forms of assessment could still be used. However, for matric learners, scrapping the June exams may have a huge effect, since learners require quality assessed examination results to guarantee entrance into higher education institutions.

Shortening of school holidays may not have a huge impact on learners, as this system has been in operation for many years. Many of the best performing schools shorten the school holidays to assist learners in Grades 11 and 12. In many schools, learners continue with normal schooling during the June holidays and rest during the last week of the holiday.  This strategy is already being used by the best performing schools in their quest to support learners to achieve excellent matric results. Depending on the number of days lost during the national lockdown, the option of shortening the June holidays may be the most commendable.

At face value, the strategy to lengthen school days may be the most preferred, as a number of schools in the country are already implementing it at a deeper level. Increasing the number of teaching hours may, however, have an adverse impact on the learners, who may experience enormous mental exhaustion. If the day is lengthened, it is advisable to consider not more than five hours per week.  

Deliver modern and classroom-targeted technologies 
To complement the time recovery mentioned above, there would be a need for a series of changes in some, if not all, the fundamental elements of the effective provision of teaching and learning discussed below. First, change in pedagogical approaches is inevitable. Therefore, classroom teaching will not be the same again. Second, teachers will be compelled to adapt to the use of assessment data in their endeavours to drive teaching and learning. Third, teaching in the 4IR will no longer be negotiable, but will demand advanced skills to deliver modern and classroom-targeted technologies.

Fourth, it will be crucial for teachers to acquire innovative skills to manage students’ undesirable behaviour and conduct. Fifth, immense attention to curriculum mapping, integrated learning, and lesson planning will be required. Last, pastoral care responsibilities that include social and emotional support strategies will help provide the foundation to support teaching and learning. 

In conclusion, the principal elements that make teaching and learning possible and attainable, are the teachers who will be required to learn new skills and approaches to fast-track recovery of learning. If the lockdown is lifted and schools are reopened, the number of learners must be reduced dramatically from the average of 50 to a maximum of 20 learners in a classroom in order to maintain social distancing.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
