Unlike most videoconferencing systems, the new videoconferencing system we have developed allows sessions between a native English teacher and a non-native second language learner to be recorded and edited for later reuse for educational instruction purposes as a teaching aid thus enhancing explanations and comments about pronunciation and intonation. To develop easy-to-use tools for adding such enhancements, a new paradigm called video correction is proposed implementing as a video correction system so that the learner can understand the teacher's comments as if they were corrections on paper. The prototype system, called Viclle (Vi deo-based C ommunication L anguage L earning System),support both a teacher (a native English speaker) and a learner (non-native speaker) with video correction and communication. A new XML schema, called VCML (V ideo-based C orrection M arkup L anguage), is exploited to represent pedagogical correction essentially in a compact text format so that both teacher and learner can communicate through e-mail without sending video files back and forth. In addition, VCML relates the teacher's corrections to the video with links, and it includes the learner's feedback. Therefore, the teacher and the learner can communicate with each other by using the VCML document only.
