This paper describes a blended learning support system that uses ubiquitous equipments and promotes students’ review before class time. This system works in a wireless LAN-enabled classroom and requires a student to carry his/her student RFID tag and PDA equipped with a RFID tag reader. The classroom RFID tag is attached to the classroom door. The student comes to the classroom and sends his/her authentication (attendance) information to LMS by RFID-reading the two RFID tags. Immediately after successful authentication, review material is displayed on his/her PDA according to his/her understanding level. This means that the student is given an opportunity to review within short period before class time. Through an experimental use of the system, we obtained questionnaire data that short period review can be helpful for understanding content of the class.
