Abstract
In this symposium, we discuss the re-conceptualisation of problem solving in the school mathematics curriculum that is part of the M-ProSE project (Mathematical Problem Solving for Everyone). We propose the use of mathematics practical lessons, similar to practical lessons in science education and the use of an assessment rubric that focuses on key processes of problem solving. We also focus on teacher preparation for a seamless implementation of the problem solving curriculum in school. The following three papers will be presented during the symposium:
