Task-Based Language Teaching by Daniel O. Jackson is a concise guide to task-based language teaching (TBLT) for language instructors, teacher educators, and others. The book adopts a cognitive-interactionist stance and aims to make TBLT more accessible. It covers key concepts, issues, and practical applications of TBLT, serving as a reference for practitioners. The book is organized into six sections, starting with an introduction to TBLT, followed by discussions on curriculum design, contextual applications, research, teacher roles, and an epilogue. The first section introduces key definitions and task types, including jigsaw, information gap, problem-solving, decision-making, and opinion exchange tasks. It also discusses task design features and their importance in task implementation. The second section outlines the stages of building a TBLT curriculum, contrasting it with traditional approaches. It includes examples and theoretical frameworks to support the stages of curriculum development. Section three presents case studies from diverse geographical and educational settings, illustrating how TBLT can be adapted to local contexts. Section four reviews TBLT studies from 2011 to 2021, focusing on design, mode, preparation, interaction, and repetition. Section five explores teachers' experiences with TBLT, emphasizing the role of teachers in task implementation. The epilogue discusses the transformative purposes of TBLT, including creating rich input environments and empowering learners. The book's strengths include its accessibility, structured organization, and practical examples. It provides a balanced overview of both task-as-workplan and task-in-process, emphasizing the importance of task implementation. However, the book has some limitations, such as superficial treatment of some topics and a focus on adult learners rather than young learners. Despite these, the book is a valuable resource for teachers and teacher educators, especially in seminars and workshops. It contributes significantly to language education by offering a concise overview of TBLT and its applications in diverse contexts.Task-Based Language Teaching by Daniel O.
