“A quality higher-education learning experience is a transformative experience for both students and lecturers who develop their minds in criticality, as well as social and self-identity, in addition to other skills and competencies.” This was the message from Dr Patience Mukwambo at the launch of her recently published book – ‘Quality in Higher Education as a Tool for Human Development: Enhancing Teaching and Learning in Zimbabwe’.

The book is a product of her doctoral research and was launched by the office of the SARChI Chair in Higher Education and Human Development, where Dr Mukwambo is a full-time researcher and was introduced at an event held at the Bloemfontein campus of the University of the Free State (UFS) on 21 October 2019. 

Depressing higher-education system

Dr Mukwambo was joined in conversation by Prof Brian Raftopoulos, a Mellon Senior Research Mentor in the Centre for Humanities Research at University of the Western Cape. 

Both scholars testified to the concept of critical thinking, alluding to the depressing state of education in Zimbabwe due to limitations posed by a non-expanding economy and a repressive political space. 

Prof Raftopoulos told the audience the idea of critical thinking has a long genealogy in radical thought which has deepened its roots in modern-day society. 

“What you have seen through the introduction of STEM (Science, Technology, Engineering, and Mathematics), is the increasing idea of functionalising education for a work economy. More often than not, you will hear the state saying it is up to school-leavers to create their own jobs,” said Prof Raftopoulos. According to Dr Mukwambo, part of the challenge is that “critical thinking is omitted on purpose and therefore universities lack a moral compass to work from”.

“While the broader economy might be constraining there are opportunities to develop critical thinking in the classroom, although it might not be uniform across all universities,” said Dr Mukwambo.

Equipping graduates with critical-thinking skills contributes to a range of benefits, such as improved wellbeing, economic outcomes, political engagement, and human capital formation. Quality in teaching and learning is therefore indeed a step in the right direction, towards social justice.

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
