Second Language Educational Experiences for Adult Learners provides an up-to-date review of the theory and practice of adult second language education. The primary objective is to introduce core ideas that should inform the design, development, and delivery of language learning experiences that take the typical forms of materials, courses, teaching, and assessment. Divided into three sections, the book first addresses what we know about adult second language acquisition and how individuals may acquire languages differently from each other. In the second section, key educational design elements—from pedagogical methods to curriculum to assessment—are then introduced from the perspective of research-based understandings about effective practices. Rounding out the volume is an overview of critical issues for language educational innovation, including supporting teachers, localizing materials and instruction, evaluating and improving education, and working with technology. Each chapter concludes with a set of recommended “design principles” that should guide readers toward high-quality, valuable, and empirically supported language educational experiences. This volume will be of interest to researchers and students investigating instructed language learning, designers creating useful language learning materials, and language teaching innovators seeking to improve outcomes in diverse instructional settings around the world.
