ABSTRACT
The professional development courses presented in this chapter are rooted in the DZLM (German Centre for Mathematics Teacher education). The DZLM is a joint research and development institution of seven German universities aiming at setting new standards and prototypes for the professionalization of mathematics teachers. To give an insight view of the work of DZLM, we present exemplarily two programmes for upper secondary teachers in the context of new curricula based on the most recent national standards for mathematics education at the upper secondary level. These two programmes support teachers to implement the new standards, which focus on process- and content-related competences and have for the first time digital tools as a mandatory requirement. In both courses, we initiate the use of these tools with a serving function in supporting the development of process- and content-related competences. One programme focuses on digital tools fostering process-related competences such as modelling, flexible use of representations and problem-solving. The other programme is related to probability and statistics as content, where teachers articulate high demands for professional development. Both programmes have been accompanied by research investigating the effects on teachers’ beliefs and knowledge.
