Abstract
Laptop computers and tablet PCs have become common, and one-to-one computing environments are prepared in many educational institutions. In this paper, the authors developed a desktop sharing application, which referred to as "LiveScreenBoard", to share personal desktop situations among members in a group, in order to support emergent division of labor in collaborative learning with personal computers in face-to-face setting. LiveScreenBoard retrieves and distributes a real time update of the status of each member's desktop status every 30 seconds. The result of the evaluation showed that LiveScreenBoard allowed learners to keep tracks of each other's status in their group activity, with awareness enough to recognize problems or fine performances of their partners. In addition, LiveScreenBoard allowed the learners to realize their partners recognized their own desktop status; accordingly, the learners could reflect on their performance, provide each other with guidance, and incorporate their partner's approach of learning.
