More about the speaker:

Tomas Vetrik received two scholarships from foreign countries during his PhD study. He spent one semester of his PhD study at the Vienna University of Technology in Austria, and two semesters at the Technion – Israel Institute of Technology. He was the only postgraduate student from Slovakia to receive a scholarship from the Israeli government in 2006. Tomas Vetrik joined the University of the Free State in 2014, after his postdoctoral research at the University of KwaZulu-Natal and working at the UniversityPretoria. His research area is graph theory. He is mainly focusing on the degree-diameter problem, graph indices, and metric dimension of graphs. He is an NRF-rated researcher and has produced about 75 research papers (approximately 25 of them as a single author).

Three PhD students and three MSc students have completed their studies under his supervision. He has presented seminar talks at 24 universities from 15 different countries.

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.
