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 IBI 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 IBI approach. This book serves researchers, instructors, course coordinators, program directors, and developers of instructional materials.
