Dr Fumane Khanare opted to integrate poetry into her teaching practice, using innovative ways to keep the curriculum afloat and interesting at the same time.

The Coronavirus (COVID-19) lockdown has severely affected teaching and learning. Lecturers and students alike have been challenged to explore innovative ways to keep the curriculum afloat and interesting at the same time. Dr Fumane Khanare, Senior Lecturer in the Faculty of Education, has opted to integrate poetry into her teaching practice. Her Community Psychology students have shifted over the past few months from merely interacting with the course material to generating their own content.

Learning in the times of lockdown

According to Dr Khanare, the psycho-social impact of COVID-19 remains unknown as the world grapples with a backlog of information, accompanied by loss and grief. However, collaborative strides are being made in the right direction, considering that this is unchartered territory. “Recommendations advocating for online teaching and learning, bidding for free data, and laptops for the majority of students, especially those at the peripheries of a mainstream economy – and of course physical distancing-adhering wellness programmes – may enable effective teaching and learning.” 

Why poetry?

“Lurched in at the deep end and taking into account the students who are not well-equipped with the integration of information and communications technology in learning, is significant. This realisation led me to seek ways to help my students develop a deeper understanding and critical-thinking skills, as well as becoming self-motivated students amid COVID-19,” explained Dr Khanare.

Students were first tasked with analysing the poetry of Butler-Kisber (2002). Thereafter, they were required to write poems about COVID-19, underpinned by the Community Psychology in Education module. “The activity provided students with an opportunity to use and reinforce concepts learnt prior to the lockdown, monitor their own understanding and progress, plus motivate them to come to the lecture prepared – a function known as co-creators of knowledge,” she said.

The artistic creations of these students were circulated among peers for review, allowing them to move from the peripheries to the centre of knowledge production amid a pandemic. 

Digitising the education space

Beyond the classroom, Dr Khanare will attend the 2020 Women Academics in Higher Education Virtual Symposium. As the co-convener of the World Education Research Association-International Research Network, she continues to ensure that research-related activities continue, despite a ban on international travel.

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.

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.
