This document provides an overview of research informed teaching (RIT). It begins by defining key terms like research and teaching. It then discusses the history of RIT, from medieval universities which focused on training clergy, to modern universities which emphasize a "facts first" approach. The document outlines different models of RIT and dispels three common myths about it. Five compelling reasons for practicing RIT are presented: it develops students' critical thinking, aligns with degree structures, introduces complexity and is exciting/authentic. Strategies for institutions to support RIT are discussed.
