Systematic Reviews by Carole Torgerson serves as a foundational guide for students and researchers performing structured research syntheses within the field of education. The text distinguishes systematic reviews from traditional narrative reviews by emphasizing explicit methodology, rigorous quality appraisal, and the reduction of author bias. While the author acknowledges that these techniques originated in health care, she argues for their essential role in creating evidence-based policy and identifying "what works" in classrooms. The book specifically highlights the randomized controlled trial (RCT) as the "gold standard" for determining effectiveness, while also explaining the statistical role of meta-analysis. By providing a step-by-step rationale and a detailed glossary of technical terms, the source aims to improve the scientific rigor and transparency of educational research. Evaluation of potential publication bias and the history of research synthesis collaborations, such as the Cochrane and Campbell Collaborations, are also discussed to provide a comprehensive academic context.
