A guide on models and modelling

A new curriculum and examination programme for upper secondary school physics was recently introduced in the Netherlands. Models and modelling play an important role herein. But teachers need help in developing their PCK in this area. To this end we developed a modelling guide, which introduces physics teachers to the role of modelling in science and science education, the scientific base of teaching and learning routes of modelling in pre-university education, and curriculum relevant computer models. We discuss the design and contents of this guide, and teachers' first impressions when it was presented to them in workshops
