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.

Mathematical problem-solving solutions found in African indigenous games
2015-04-02

A recent study by Dr Tshele Moloi, a Mathematics Education lecturer at the Qwaqwa Campus, revealed that games such as Diketo or Morabaraba enhance the understanding of abstract mathematical concepts in children.  Diketo is a children’s game where 10 small stones or marbles and 1 ghoen or big stone are made available to each player. A small hole about 5cm deep is dug in which the small stones are placed for the players.

During this game of Diketo, learners can identify the variables involved – both dependent and independent.  In round one of the game, it was found that the stones scooped out of the hole can be described by the pattern: f(n)= -n/2   +  21/2 , (where n denotes the throwing of the ghoen). Stones placed in the hole can be illustrated by the pattern:  f(m)= -m/2   +  10, (where m denotes the throwing of the ghoen). There are many patterns that can be obtained when the players are in round two.

The patterns which emanate from rounds one, two, and three can be put on the Cartesian Plane, which can then demonstrate the linear functions.
