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 preservice 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 preservice 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.
