This fascinating presentation of current research undoes numerous myths about how we most effectively learn new words in a second language. In clear, reader-friendly text, the author details the successful approach of input-based incremental vocabulary instruction, which emphasizes the presentation of target vocabulary as input early on and the incremental (gradual) build-up of different aspects of vocabulary knowledge over time. Instructors can take advantage of numerous practical classroom activities to support the input-based incremental approach. This book serves researchers, instructors, course coordinators, program directors, and developers of instructional materials.
