<p>'This book provides a thorough examination of the role of social factors in second language acquisition, clearly demonstrating the importance of sociolinguistic perspectives in the field of second language acquisition as well as in the second language classroom. It is an outstanding resource for students and scholars interested in the impact of social factors on learner language.' – <em>Carol Klee, Department of Spanish & Portuguese Studies, University of Minnesota, USA</em></p><p>'With this publication, the authors make an invaluable contribution to the research and literature in second language acquisition, complementing traditional cognitive and pedagogical treatments with a properly sociolinguistic approach and, in so doing, bring new perspectives that promise to reinvigorate the discipline.' – <em>Almeida Jacqueline Toribio, Department of Spanish & Portuguese, The University of Texas at Austin, USA</em></p><p>'Geeslin and Yim Long’s book is a very pleasant and interesting read which suits the intended audience, i.e. ''readers with backgrounds in second language acquisition, sociolinguistics, psycholinguistics, speech and hearing sciences, anthropology, linguistics, and education'' (xix). It will be a valued resource for all teachers, teachers’ educators, researchers and students of applied linguistics who wish to rethink and learn more about the importance of sociolinguistic perspectives in the field of second language acquisition and instruction, and who have so far lacked such a contribution.' - <em>Valeria Buttini-Bailey, Universität Basel, The LINGUIST LIST</em></p>
