The National Astronomy Teaching Summit is a professional conference bringing together dedicated astronomy and planetary sciences educators to share innovative teaching techniques and successful instructional strategies that increase students' engagement, achievement, and motivation. Traditionally focused on improving teaching and learning for the introductory college astronomy survey courses for non-science majoring undergraduates, the growing Summit event now brings together a wider variety of astronomy educators and outreach enthusiasts at all levels where astronomy and planetary science is taught: K-12, College-101, Graduate School, Planetariums/Museums, and Amateur Astronomy Groups. The summit includes formal presentations, interactive workshops, and round-table discussions all designed around astronomy teaching innovations. Submitted abstracts have been peer-reviewed and conference is organized by a respected program committee.
