Dr Michael von Maltitz embraces the possibilities that the internet provides for education. He wants his students to be comfortable evaluating and using information from the internet to solve their problems.
“My research in teaching and learning is driven mostly by curiosity – when I feel something is not working in a class, I look for alternatives and I am quick to adopt something new.”

This is how Dr Michael von Maltitz approaches his research. This perspective on things is also what brought him an award from the Centre for Teaching and Learning (CTL) during the Annual UFS Excellence in Learning and Teaching Conference 2020 that was held on 21 and 22 September 2020. 

Dr Von Maltitz, who is Programme Director and Senior Lecturer in the Department of Mathematical Statistics and Actuarial Science, received an Excellence in Learning and Teaching award in the category Technology Enhanced Learning. 

He teaches Causal Inference and Generalised Linear Models for third-year Mathematical Statistics students, and Sampling Distribution Theory for second-year Mathematical Statistics students. 

Follow the lead of practice

Grabbing the attention of the judges, he believes, was his passion for new teaching and learning methods. He is also of the opinion that it is important to embrace the information – the incredible amount of free, valuable content online – that is freely available to staff and students all the time.

“I am passionate about the fact that we need to stop asking our students to write tests when this is not done in that student’s industry. At university, we need to assess knowledge in the same way it is assessed in practice. This ultimately means that information capturing (which is what we expect from students in a textbook-to-test format) should be left to machines and the internet. Critical thinking, knowledge valuation, and self-assessment (i.e. facets of learning how to learn) should be developed while at university.”

“The internet is everywhere now, and we’re fooling ourselves if we think we can teach our students how to navigate their futures without incorporating the internet into our teachings,” he adds.

Dr Von Maltitz embraces the possibilities that the internet provides. “Hopefully, when my students are finished with my modules, they will be more comfortable evaluating and using information from the internet to solve their problems, like I do on a day-to-day basis,” he says. 

Seeking new methods

On receiving this award, Dr Von Maltitz voiced his gratitude for the opportunity to present his ideas and practices; “it suggests that others might find my work useful”.

He says that it helps him feel justified in trying new methods in teaching and learning every year.

Dr Von Maltitz has big plans for the next five years. He wants to make it to Associate Professor, partially on the strength of his teaching and learning portfolio.

“My goal is to ensure that my gradual exploration of my research field in Mathematical Statistics always raises the impact of my modules for my students and improves the quality and quantity of my postgraduate supervision. I also hope that my teaching and learning research will continue to improve my ability to transform my students into life-long learners.”

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
