Did you hear the one about the funny lecturer?

Prof Jannie Pretorius uses an engaging and humorous teaching style that keeps his Life Science and Natural Science students fascinated and engaged.

Once upon a time, there was a monotonous teacher: the students did not like his lectures. Nothing interesting ever happened. The teacher grew old and retired. The end. Or not? According to research, teaching can be a humorous, fun, and enjoyable experience if you do it differently.

Mr Bean videos and Trevor Noah in the class

Prof Jannie Pretorius, a lecturer in the School of Mathematics, Natural Sciences, and Technology, uses an engaging and humorous teaching style that keeps his Life Science and Natural Science students fascinated and engaged. When starting out at the UFS, Prof Jannie wondered about using humour in a “serious tertiary environment.” He soon discovered that students, like most other people, also enjoy appropriate humour.

Using humour in education turned into a research project, and Prof Pretorius found himself showing Mr Bean videos and watching Trevor Noah shows to develop a lesson where the impact of using intentional humour was studied by measuring students’ reactions. An example from the transcription of his class on the mating habits of the praying mantis, where the female often bites the male’s head off to eat him for nourishment, shows how fun can be integrated into learning:

So, it seems that the praying mantis is like – praying; the male is saying: ‘Please don’t eat me, Sylvia, please!’… (laughter) … and she would pray back and say, ‘Please, Ronnie, I can’t resist you.’ (laughter).

Sensitive to their learners’ preferences

Despite the classes being fun, Prof Pretorius also cautions that it is important for teachers to be sensitive to their learners’ preferences and cultural backgrounds when using humour. “There is always an element of risk in the use of humour. As such, humour should always be used in a respectful and inclusive manner to ensure that all learners feel comfortable and included in the classroom.”

Prof Pretorius recognises that the use of humour depends on educators’ personal preferences. Ultimately, it is about what the students learn.

Researchers reach out across continents in giraffe research

2015-09-18

Dr Francois Deacon and Prof Fred Bercovitch
busy with field work.

Researcher Dr Francois Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the University of the Free State is conducting research with renowned wildlife scientist, Prof Fred Bercovitch, from the Center for International Collaboration and Advanced Studies in Primatology, Kyoto University Primate Research Institute in Japan.

Dr Deacon’s ground-breaking research has attracted international media attention. Together with Prof Nico Smit, he equipped giraffes with GPS collars, and conducted research based on this initiative. “Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.”

Prof Bercovitch was involved with GPS tracking from elephants to koala bears.

Some of the highlights of the joint research on giraffes by Dr Deacon and Prof Bercovitch focus on:

• How much time do certain giraffes spend with, and away from, one another
• How do the home ranges of herds and individual giraffe overlap
• Do genetically-related animals spend more time together than non-genetically-related animals
• How much time do the young bulls, adult bulls, and dominant bulls spend with cow herds
• Herd interactions and social behaviours of giraffe
• The role of the veld and diet on animal behaviour and distribution

Their research article, “Gazing at a giraffe gyroscope: Where are we going?”, which was published in the African Journal of Ecology, assesses recent research by exploring five primary questions:

- How many (sub) species of giraffe exist?
- What are the dynamics of giraffe herds?
- How do giraffe communicate?
- What is the role of sexual selection in giraffe reproduction?
- How many giraffe reside in Africa?

They conclude this article by emphasising that the most essential issue is to develop conservation management plans that will save a wonderful species from extinction, and which will also enable scientists to conduct additional research aimed at answering their five questions.

In addition, they are working together on a grand proposal to get National Geographic to cover their work.
