One of the authors (Shigeru Ikuta) has organized a collaborative learning community with schoolteachers to provide reasonable accommodations for students with disabilities using newly developed multimedia-enabled dot codes. He created “Post-It-like” sticker icons on which dot codes were printed; 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 self-made contents 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 teaching materials for students in classes. The present newly developed software and tools are quite useful to support the students with various difficulties in inclusive learning settings.
