This final chapter revisits all the issues discussed in the textbook in light of their applicability to the real classroom, that is, the relationship between research and practice. It argues for the importance of considering the usefulness of research if and when a researcher hopes to influence classroom teaching via their research. The chapter begins with a description as to how research in general is connected to our daily lives (e.g., medicine, engineering, education). It then overviews the research examining the impact of research on educational practices including second language teaching. Practical and epistemological obstacles to bridging the research–practice gap from practitioners’ and researchers’ sides are discussed. The chapter proposes a variety of actions that practitioners and researchers can take in order to foster a bidirectional, constructive, productive, equitable, and mutually beneficial relationship. The chapter ends with a series of activities designed to ensure the learning outcomes from the textbook.
