This book introduces an approach for making principled decisions about the use of technologies specifically in Applied Linguistics. The research is grounded in the growing area of 'blended learning' that seeks to combine face-to-face instruction with online-based interactions. With both novice and experienced instructors in mind, Gruba and Hinkleman explain how to make decisions regarding computers in settings that are primarily taught face to face. Written in an accessible manner, and drawing on research and examples from a variety of contexts to illustrate and justify blended learning concepts, this will be a useful resource for language teachers, TESOL teachers and teacher educators.
