Understanding and organizing mathematics education as a design science

Origins and new developments

抄録

The objective of this paper is

(1) to revisit briefly the conception of mathematics education as a design science as it has been evolving alongside developmental research in the project "Mathe 2000" from 1987 to 2012

(2) to report in some detail on recent developments in the follow-up project "Mathe 2000+," as concerns both conceptual and practical issues.

The paper is a plea for appreciating and (re-)installing "well-understood mathematics" as the natural foundation for teaching and learning mathematics.
