The Hollywood movie, Contagion, acutely reminded me of the impact of COVID-19 on our education our education system. The many parallels between this movie and what is unfolding worldwide today in unbelievable. Nine years ago, who would have predicted that the world would find itself right in the middle of the plot and enacting the scenes in Contagion?

There is growing concern about our education system with many asking whether the school year is ruined.

For some it may be ruined and for others less so. Parents for disadvantaged communities do not have the means, knowledge and resources to support their children’s learning during the lockdown whereas those from more advantaged communities may access information on Department of Basic Education (DBE) and other websites to support home schooling during these times. For those who did not have these opportunities the loss of school time may thus have a much greater impact.

Embracing homeschooling
However, the school calendar year may equally be extended to early next year. In any event, we already have a system that allows for aggrotats, supplementary exams that runs into the new year, each year. The academic year can be aligned to close accommodate the lost time.

This is the right time for parents to embrace homeschooling of their children. UNESCO’s “COVID-19 Education response” provides a list of educational applications, platforms and resources aims to help parents, teachers, schools and school administrators facilitate student learning and provide psychosocial support during periods of school closure. Most of the solutions are free and many cater to multiple languages. The lists are categorised based on distance learning needs and most of them offer functionalities across multiple categories (https://en.unesco.org/covid19/educationresponse/solutions).

On the one hand, for the majority of learners and students in South Africa, especially from impoverished communities, distance learning will pose a great challenge. Majority of these communities have less access to digital devices and online solutions. The DBE should work with the SABC and consider opening a free 24 hours learning channel, as a platform to provide further support to distance learning and teaching. Radio remains the cheapest and most effective means for this

On the other hand, the situation is different with some private or IEB schools. Most learners from these schools are already trained to use distance learning platforms.  For example, during this lockdown, my 13year old niece starts her school day at 07:30 every day without fail. The school uses several strategies including the Microsoft Teams to support teaching and learning. Each learner has a laptop, completes home-work, assignments and write open book tests. In this scenario, at least 80% of efficient learning and teaching occurs. The difference between the two scenarios is a matter of inequalities, equity and poverty which still prevalent in South Africa.

An unequal school system
For many years the slogan was: “Liberation first then education” maybe it is time for “life and health first”. Even in the most difficult times people have found a way to learn – think of those on Robin Island in the apartheid years. We should imitate their example and not wait for the government to provide. Maybe libraries are an essential function that should remain open in these times.

Protracted student protests in South Africa over the past few years gave universities an opportunity to explore online education as an alternative to contact teaching and learning, and have put them in a better position to deal with current shutdowns necessitated by the need to contain COVID-19.

The pandemic exposed the glaring inequalities, equity and poverty that continues to exist, in particular, in education systems and country in general. Those who have the latitude to remain indoors and maintain the social distancing are the middle and upper classes of our society. These groups have access to data to support online educational programs, while the poor barely survive to put food on their tables.

For many years the world was expecting a virus that could spread globally (e.g. the swine flu) but nothing was done. With the myriad of challenges facing, including downgrading to a junk state, funds depleted through corruption at various levels, our country could not be at a worse position than now.

Lessons from the lockdown
One lessons from the lockdown has exposed the failures and shortcomings of not only our education system, but also the entire ecosystem. Huge inequalities still exist in education systems across the globe. Universities are grappling with a myriad of problems including teaching online.  The COVID-19 pandemic forced campuses to shut down and move many functions like graduation, examinations, conferences and other collaborations to the back. Another positive outcome of the pandemic is the sense of unity it created among political, cultural, religious and social organisations in South Africa and across the globe. Consequently, the most important lesson is that lives matter more than education.

As our president, Cyril Ramaphosa said, “We are currently in unchartered territory, which we have never had to navigate before”. It is therefore, very difficult to forecast the full degree of the short-, medium- or long-term impacts of the COVID-19 pandemic on the education system. The longer the virus remains, the greater and more permanent changes may be. Certain things will probably change forever. Not only will our conception of going to office to work alter, but also our whole conceptualization of what a university is will change. We will probably see universities becoming more and virtual and operated from a highly decentralized basis.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
