Book excerpt: This concise collection critically reflects on mobile assisted language learning research across educational stages, from early childhood through to university settings. // The volume traces the development of MALL practices through researchers' and teachers’ efforts to make sense of the impact of mobile technologies on formal and informal second language learning and development. The chapters explore a range of topics around mobile learning design, implementation, and affordances across different educational and geographic contexts, drawing on both qualitative and quantitative perspectives. In so doing, the book creates a broader conversation around the importance of continuity in the successful integration of MALL practices into L2 learning curricula across the educational lifespan. // This book will appeal to students and scholars in applied linguistics and language teaching and learning, especially to those with a specific interest in mobile technologies.
