Giving a voice to international students and expatriate scholars, this volume is a thought-provoking call for multilinguality and social and epistemic justice in research, teaching and learning in Higher Education. Drawing on solid literature and personal experiences, Yanaprasart and Melo-Pfeifer aptly challenge the uniformization mindset in the academy while arguing for social inclusiveness and balance between global and local views and goals. * Feliciano Chimbutane, Eduardo Mondlane University, Mozambique * This timely volume explores how multilingualism is reshaping higher education amid global mobility and shifting policies. It challenges traditional language hierarchies, redefines linguistic legitimacy, and offers fresh, inclusive approaches to teaching and learning. A must-read and an essential resource for scholars, educators, and policymakers eager to rethink language use and drive meaningful, equitable change and innovation in academia. * Danièle Moore, Simon Fraser University, Canada and Diltec, Université Paris 3-Sorbonne Nouvelle, France * This much-needed book critically examines language ideologies and practices in university teaching and learning. It reconceptualizes internationalization as complex 'internationalizationS' explores its links with multilingualism and 'multiperspectivity', and highlights the often-overlooked multilingual repertoires of teachers and students. Its critical, polycentric approach makes it a valuable contribution to language policy, academic governance, and the international scholarly community. * Laurent Gajo, Université de Genève, Switzerland *
