This study examines the text-chat interaction of second language learners and teacher trainees engaged in an online exchange linking classes in two countries: Sweden and the United States. During the semester, students met online for 6 sessions using the chat program Live Messenger. As part of the exchange, each U.S. student served as a tutor and chat partner for Swedish students on four writing tasks. These tasks were designed in accordance with language features (i.e. the zero article, agreement, possessives) and topics (i.e. human rights, environmental issues, Swedish and US culture) relevant for both classes. Chatscripts from focal participants' interactions were analyzed to explore the potential to foster attention to form in text-chat based telecollaboration that emphasized L2 writing.
