A portable CSCL system "edutab box" with an autonomous wireless network

Due to the recent widespread adoption of tablet terminals, opportunities for collaborative learning using tablet terminals are increasing. We developed a portable CSCL (Computer Supported Collaborative Learning) system with a small-sized PC, the Raspberry Pi2. The system provides an autonomous wireless network without any extra network systems because it incorporate a wireless LAN access point and network servers. Using this system we could realize collaborative learning using tablet terminals in standard classrooms with no additional equipment. In this paper, we describe the design of the system. We also implemented the system and experimentally evaluated its.
