The document discusses using synchronous computer-mediated communication (CMC) for language learning activities. It describes how CMC can encourage more equal participation than in-person group work and allows learners time to prepare. A variety of tools are presented for synchronous CMC, including chat programs, video conferencing, and learning management system classrooms. Examples of activities that can be done through synchronous CMC include discussions, project collaboration, study groups, and holding virtual classes. The document demonstrates how to use Blackboard Collaborate and suggests trying other tools like Google Hangouts, Skype, TokBox, and IRC in small groups.
