We have developed learning support systems, named SEGODON and SEGODON-PDA. SEGODON consists of personal computers and a Local Area Network (LAN). SEGODON-PDA consists of Personal Digital Assistants (PDAs) and wireless LAN. We have applied them to classes, the results of which show that the class using SEGODON was not superior to the usual class which did not use digital equipment. The result of the end-term examination was almost the same regardless of the systems’ used. The result of the evaluation using SEGODON-PDA was comparatively high. We analyzed the results and found that good results were derived from the curiosity of students in the class using new digital equipment like a PDA.
