Coordination processes in computer supported collaborative writing

In the COSAR-project a computer-supported collaborative learning environment enables students to collaborate in writing an argumentative essay. The TC3 groupware environment (TC3: Text Composer, Computer supported and Collaborative) offers access to relevant information sources, a private notepad, a chat facility including a chat history, and a shared word-processor. Planning tools for writing - a shared argumentation diagram for content generation and a shared outline facility for content linearization - were added to the basic TC3 environment. About 145 pairs of high school students completed essays on organ donation or cloning in the TC3 environment. We analyzed the logged discussion ('chats') and activity protocols for task-related processes present during discussion and collaboration. Processes looked into are planning, gathering information and composing the essay, as well as collaborative processes such as coordinating, turn taking and time management. Our main research question is how task-related planning activities and collaborative coordination with or without the help of planning tools relate to the quality of the resulting argumentative texts. Overall coordination and planning of the writing activities on a meta-level and on a content level were found to be crucial for the quality of the text.
