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.”

Research into surrogate milk important to wildlife conservation

Research is being done at the University of the Free State (UFS) to analyse and synthetically imitate the unique milk of various wildlife species. This research is not only of scientific value, but also serves the conservation of South Africa’s wildlife species. At the forefront of this research is Prof Garry Osthoff from the Department of Microbial, Biochemical and Food Biotechnology.

Orphaned rhino calf pulled through with surrogate milk

“There is still a lot of research to be done. Naturally the research is of scientific importance, but with surrogate milk having the same composition as the mother’s milk of a specific species, orphaned calves or cubs of that species could be pulled through during a difficult time of weaning. Bearing in mind that exotic animals fetch thousands and even millions of rands at auctions, it goes without saying a game farmer will do everything possible to provide only the best nourishment to such an orphaned animal. In such a case, synthetically-manufactured milk would be the right choice,” says Prof Osthoff.

The fruits of his research were recently demonstrated in Germany when a rhino calf was left orphaned in the Leipzig Zoo. Prof Osthoff’s article: “Milk composition of a free-ranging white rhinoceros during late lactation” was used as a directive for applying surrogate milk for horse foals (which is already commercially available), since the composition of horse and rhino milk largely corresponds. The surrogate milk was used with great success and the rhino calf is flourishing. He mentions that such an orphan is often given the wrong nourishment with the best intentions, resulting in the starvation of the animal despite the amount of cow’s milk it devours.

Milk formula for baby elephants in the pipeline
With baby elephants left orphaned due to the increase in elephant poaching for their ivory, several attempts have been made to create a milk formula in order to feed these elephants. To date, many elephants have died in captivity from side effects such as diarrhoea as a result of the surrogate formula which they were fed.

Prof Osthoff recently received a consignment of frozen milk which he, together with researchers from Zimbabwe, will use to work on a milk formula for elephants. They are studying the milk in a full lactation period of two years. During lactation, the composition of the milk changes to such an extent that a single surrogate formula will not be sufficient. Four different formulas should probably be designed.

Prof Osthoff says that of the different species he has researched, elephants are the most interesting and deviate most from the known species.

Although his research to develop surrogate milk is adding much value to the wildlife industry, and although he finds this part of his work very exciting, his research focus is on food science and nutrition. “What is currently authentic in milk research is the study of the fat globules with content, the structure and composition of the casein micelle, and the prebiotic sugars. The knowledge which is gained helps to improve the processing, development of new food products, and development of food products for health purposes,” says Prof Osthoff.
