Hidden Dimensions in the Professional Development of Mathematics Teachers

Hidden Dimensions in the Professional Development of Mathematics Teachers presents the field of mathematics teacher professional development both from a theoretical and an empirical perspective. In particular, the initiative Mathematics Done Differently that has been run in Germany is presented, in whose context the data of the empirical study was gathered. The empirical findings led to postulating a model describing teachers' individual growth pathways and to providing implications for constructing practices that are based on what teachers really need.
