250114 VO Problems in teaching mathematics (2009W)

Functions run like a thread through the whole school mathematics. In this lecture a survey on the role of functions from grade 5 to grade 12 is given. It ranges from didactical background considerations via empirical investigations to concrete teaching proposals. Main topics: development of function concept (from a historical and didactical point of view), basic ideas of functions and specific function types, representation of functions, methodical questions of different types.
