Original teaching materials with multimedia-enabled dot codes were created for use with students with various disabilities. The “Post-it-like” sticker icons on which dot codes were printed were used there; each sticker icon could be linked with up to four multimedia mediums, in addition to up to four voices/sounds. Touching a dot code icon with a speaking-pen enables audios to be replayed, and touching a dot code icon with a dot-code reader enables multimedia to be replayed. Four software packages to create contents with dot codes were developed by Gridmark Inc. The sticker icons, a speaking-pen and dot-code reader, and software packages are distributed to schoolteachers for free; they can now create original self-made teaching materials for students in their classes. This chapter presents basic information on school activities, performed in promoting sounding out words, learning sound-symbol correspondence, word recognition, and text reading.
