  • Can you show you are a good lecturer? 
    Wood, Leigh N.; Harding, Ansie (Taylor & Francis, 2007-01)
    Measurement of the quality of teaching activities is becoming increasingly important since universities are rewarding performance in terms of promotion, awards and bonuses and research is no longer the only key performance ...
  • Cause–effect analysis : improvement of a first year engineering students’ calculus teaching model 
    Van der Hoff, Quay; Harding, Ansie (Taylor and Francis, 2017)
    This study focuses on the mathematics department at a South African university and in particular on teaching of calculus to first year engineering students. The paper reports on a cause-effect analysis, often used for ...
  • Does the chalkboard still hold its own against modern technology in teaching mathematics? A case study 
    Billman, Anneli; Harding, Ansie; Engelbrecht, Johann (Taylor and Francis, 2018)

  • Review of a predator-prey model with two limit cycles 
    Van der Hoff, Quay; Harding, Ansie (Taylor and Francis, 2018)
    It is well-known that the Lotka–Volterra predator-prey model has a family of periodic orbits, but does not possess limit cycles and therefore the model is said to be structurally unstable. The Lotka–Volterra model is a ...
