Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Treatment Fidelity in Studies of Educational Intervention is a detailed guide to the increasing emphasis on methodological rigor and implementation fidelity in educational research. A timely contribution to the field, this book offers practical guidance and systematic research on the nature of implementation fidelity in experimental settings, and provides strategies for combining fidelity-related data with other data types to evaluate a program's impact in schools and other educational settings. With contributions from leading scholars in the area of research methods in education, Treatment Fidelity synthesizes recommendations for current measurement practices, case studies of recent or ongoing research programs, and technical evaluation reports on studies that measure and model fidelity as part of estimating a treatment's impact. Intended for scholars, professionals, and graduate students interested in school-based intervention, this volume presents information on how to address implementation in applied research.
