Synthesizing Research on Language Learning and Teaching: 13

The topic of research synthesis is presented in a balanced manner, as the authors also point to the limitations of this type of research. Overall, this book is important to anyone wanting to know the value and limitations of synthesizing research and to understand the variety of applications is suited to. — Ute Knoch, University of Auckland, New Zealand, on Linguist List 17.3578, 2006

This extraordinary volume raises knowledge in applied linguistics to a new level. The contents provide grounded answers to empirical questions about second language learning and teaching while pinpointing questions for future research. The masterfully edited collection offers important substantive and methodological perspectives that are relevant for researchers in all facets of second language studies. — Carol A. Chapelle, Iowa State University

This book is a valuable addition to the applied linguistics literature. It does not only provide clear guidelines on how to conduct a meta-analysis and assumes no prior knowledge of this type of secondary research, but also presents a large number of successful models from a variety of disciplines within the field of applied linguistics. — Ute Knoch, University of Auckland, New Zealand, on Linguist List 17.3578, 2006

The book is also a valuable resource to readers less interested in conducting this type of research for a number of reasons. Firstly, I agree with the opinion of the authors that a certain ethic around conducting and presenting primary research is necessary. For this, a raised awareness of how secondary research is conducted is invaluable. Some authors of primary research might not be aware of the importance of reporting e.g. effect sizes or reliability analyses. After reading this volume, the need for these becomes very clear. Secondly, the chapters in section two of the book are not only of interest and relevance to readers interested in the art of conducting research syntheses but are also of value to readers interested in the different topic areas covered. Each of these present current, state of the art research and therefore point to areas where more research is necessary. — Ute Knoch, University of Auckland, New Zealand, on Linguist List 17.3578, 2006

Overall, the authors have managed to collate a very well-structured and readable volume on a topic important to further the discipline of applied linguistics. — Ute Knoch, University of Auckland, New Zealand, on Linguist List 17.3578, 2006

Research synthesis presents a principled way to make systematic, comprehensive sense of the array of published (and unpublished) research on specific aspects of learning and teaching second languages. This volume leads the way for researchers, graduate students, and educators to understand this relatively new approach to establishing precisely what empirical research is, or is not, able to assert across a range of contexts and separate investigations. The book features key studies, useful reflections, and authoritative advice by researchers who have applied meta-analytic and other synthetic techniques to gain new, profound insights as well as to expose problems of conceptualization, methodology, and reporting in established inquiry­including research syntheses themselves. This book is a “must read” for anyone who really wants to know the value, and the pitfalls, of synthesizing research, to understand its various applications for second-language education, and to appreciate the qualities of rigor and trustworthiness required to evaluate and interpret ethically the collective results and complexities of empirical inquiry. — Alister Cumming, Ontario Institute for Studies in Education of the University of Toronto
