ab: Summary: In this research we examined and assessed the impact of
implementation of a model using authentic investigative activities for
teaching ratio and proportion in pre-service teacher education. The
model was developed following pilot studies investigating the change in
mathematical and pedagogical knowledge of pre- and in- service
mathematics teachers due to experience in authentic proportional
reasoning activities. The conclusion of the study is that application
of the model, incorporating theory and practice leads to a dramatic
positive change in the pre-service teachers’ content and pedagogical
knowledge. In addition, an improvement occurred in their attitudes and
beliefs towards learning and teaching mathematics in general, and ratio
\& proportion in particular.
