Edwin Skhosana
Edwin Skhosana is working hard to become a successful and competent actuary one day. With him is his lecturer, Dr Michael von Maltitz.

Edwin Skhosana, an Actuarial Sciences student, was described by his lecturer, Dr Michael von Maltitz of the Department of Mathematical Statistics and Actuarial Science, as ‘very quiet’ in his Causal Inference class. 

This may sound like a compliment, but it’s not.

For Dr Von Maltitz, being quiet is definitely not encouraged – not with the new teaching methods applied in class.

“See, my class is all about engagement – getting the students to watch videos on the topics, read about the methods in question, and then come to class to grill me about things they don’t understand. This change in teaching method is extremely disconcerting for many Mathematical students, who have up until now only been taught in the ‘memorise-regurgitate’ form they had ever since the start of high school,” he explains.

Future success


“My goal is to get the students to a level of understanding where they can sit down with me or with an expert in the field and have a conversation about the Mathematical Statistics topics that I teach. This is a very difficult task in such a technical module, and few students ever feel comfortable enough to engage with me actively in class in this way,” Dr Von Maltitz points out. 

Edwin is working hard towards applying the skills and knowledge he has obtained at university to become a successful and competent actuary one day. 

An important turning point was when it dawned on him how the things discussed in class could find an important practical application in so many fields.  

“This suddenly drove a spontaneous fascination in my mind that led me to engage with Dr Von Maltitz,” the previously quiet Edwin explains.

And everything changed.

Desperate to learn

Dr Von Maltitz explains: “Edwin came to my office to ask some questions. The incredible thing was that he sat down, and a conversation about the Mathematics, the foundations, and the methods just flowed between us. I have seldom had such an insightful chat about my module with a student. It was like a cascade of information just fell into place for Edwin.”

Although he sometimes still experiences his studies as challenging and grapples to adapt to the various styles of lecturing from different lecturers, Edwin now has hope for his class in Causal Inference. 

“I think Dr Von Maltitz’s way of presenting in class is excellent. It is, however, hard to grasp if you are still anchored in the old way of cramming, because he wants you to understand and be able to apply what he teaches,” says Edwin.

“It was just wonderfully refreshing to see someone so desperate to learn something (rather than just wanting to get a degree), and then actually managing to turn around a bad semester mark into such a river of understanding,” Dr Von Maltitz concludes.

Learners show how they built model racing car for international competition
2009-11-10

The Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) has sponsored a group of learners from Afrikaans Secondary School in Sasolburg to participate in the international round of the F1 in Schools Competition in London in the United Kingdom in September 2009. The F1 in Schools is a competition where schools are challenged to build compact, gas cylinder-driven model racing cars. The team, who competed with a team of Germany against the national winners of other countries, recently did a presentation for the Faculty to tell about the competition and to thank the Faculty for its sponsorship. Here are, from the left: Mr Eugene Wilsenach from F1 in Schools; Heleen van Greunen, Afrikaans Secondary School Sasolburg; Prof. Herman van Schalkwyk, Dean: Faculty of Natural and Agricultural Sciences; and Prof. Neil Heideman, Vice-Dean of the Faculty; back: Chacques van der Vyfer, goods manager; Rohan Laas, graphic designer; Wynand Holtzhausen, design manager; Scholtz Thiart, manufacturing manager; Dekker Coetsee, financial manager; and Helgaard Janse van Rensburg, team manager
