a casual teaching tool for large size computer laboratories and small size seminar classes
This paper will discuss the use of SOLAR-CATS , a teaching tool for large size computer laboratories and small size seminar classes. SOLAR-CATS uses a peer-to-peer (P2P) technology and does not need a server. SOLAR-CATS includes functions such as the remote operation of an application program on every PC in the class from one PC in the class, the sending of an image on one display in the class to all other class members' display, the interactive operation of an application with all class members, and the recording and replaying of operations on SOLAR-CATS. We have been using SOLAR-CATS for elementary computer literacy classes for several years. Each class contains about 50 students. Each student in the class could see small size letters and pictures on the display in front of him/her. We did not require support from the laboratory's manager to install the SOLAR-CATS program and to maintain the program. The program was distributed by us using USB keys. We also have used SOLAR-CATS for a smaller (three-eight students) seminar class. Students and the teacher could enjoyably deal with a subject by interacting with the class members.
