Prof Jannie Pretorius
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.

UFS takes the lead in solar heating in the Free State

The University of the Free State (UFS) took a further step in reducing its carbon footprint and its dependency on coal fired electricity with the installation of a solar heating system at one of its residences. The contractor handed the system over to the UFS on Wednesday, 2 June 2010.

The system installed at the Vergeet-my-nie Residence is the first commercial solar water heating project in both Bloemfontein and at the UFS. It is estimated that it will provide in 70% of the residence’s energy needs and save approximately R101 000 per annum in electricity cost. The project was completed at a cost of R2,4 million.

More residences at the UFS will be refurbished with solar systems as the existing heating systems in the rest of the twenty residences are due for replacement.

The energy crisis of 2008, and the challenges and necessity to reduce the use of electricity, sparked the initiative around the installation of solar heating systems at the UFS. The UFS is the second largest energy user in Bloemfontein.

Mr Nico Janse van Rensburg, Manager: Physical Planning at the UFS, says the management of the UFS saw an opportunity in the crisis and pro-actively embarked to become a market leader. Solar heating would not only alleviate the electricity problem of South Africa, but will impact the ever increasing electricity bill of the UFS.

“Protecting the environment and being on the cutting edge of technology are core issues to the UFS,” says Janse van Rensburg. “We are an educational institution and take pride in practicing what we preach.”
