This working group continues to develop a research program on the practice of launching mathematical tasks and its resulting impact on learners. Our research agenda contains two strands of inquiry exploring (1) theory and framework building concerning effective launches and (2) empirical examination of the link between launching and opportunities for students to engage in "productive struggle" while solving worthwhile mathematical tasks. Participants will (a) examine empirical data collected from K-12 mathematics teachers in order to further develop our emerging Launch Framework and (b) discuss the next steps to be taken in the development of an empirical research agenda examining launching and high demand tasks. Participants will collaborate to shape the development of the emerging research agenda and plan future research and dissemination. [For the complete proceedings, see ED606556.]
