Improvement Science in Education: A Primer provides a comprehensive overview of improvement science as a framework to guide continuous improvement and reconceptualizes improvement by centering equity and justice as the purpose of improvement. This Primer is designed to introduce improvement science, a methodology with origins in manufacturing, engineering and healthcare, to educational audiences. The book first explores the philosophical and methodological foundations of improvement science, juxtaposing it with traditional forms of research so that clear distinctions can be drawn. Chapters in the latter half of the book introduce the principles of improvement, give guidance and tools for operationalizing the principles in practice, and conclude with questions to ensure you are improving with equity in mind. Constantly reminding readers to think about who is involved and impacted, the Primer makes improvement science accessible to novices and adds critical dimensions for experienced practitioners to consider.
