This book offers essential insights into the challenges and complexities surrounding the medium of instruction (MOI), its impact on all languages and stakeholders in multilingual contexts, educational processes, developments and outcomes.   MOI has been a prominent topic in recent debates on the role of languages in education in multilingual contexts, partly because prioritizing one language over others as the medium of instruction has a profound impact on all languages and stakeholders in multilingual contexts.
