Introduction to the papers of TWG23:Implementation of research findings in mathematics education

In this introduction, we briefly present selected theoretical constructs relevant for the Thematic Working Group 23 (TWG23). We first address the topic of “implementation research” by lookinginto other research fields and domains where this topic is well-developed. Drawing on a taxonomy of so-called “implementation science” in health-care, we attempt to categorize the papers and posters of TWG23 according to their “implementation research aim” (Nilsen, 2015). Using this taxonomy, we elaborate on future perspectives for the TWG by relating to ongoing discussions in mathematics education research.
