Some of the multimedia tools used in classroom instruction include digital texts with recorded human voices or synthetic text-to-speech programs, CD-ROM storybooks and videodiscs. Other tools include computer simulations and hypermedia.
Multimedia is the presentation of information integrating text, audio, animation and graphics. Integration of multimedia into classroom instruction helps to reduce curriculum obstacles and enhance learning for students.
Text-to-speech software enables any digital content such as Web-based texts to be read aloud without necessarily synchronizing the printed information. In addition, speech synthesis may be segmented at various points to allow for feedback on sentences, passages, words or syllables. This type of multimedia provides curriculum content for visually impaired students or those who may have difficulties decoding printed text.
CD-ROM storybooks, on the other hand, provide digital text together with other features including speech, sound, animations and illustrations. In addition, some storybooks may integrate an audio version of the text. With this type of multimedia, the inclusion of valuable literacy supports may enrich reluctant readers and learners with low literacy skills.
Videodiscs or video provide a way of contextualizing curriculum content and instructions across the curriculum. For instance, video may be used to broadcast mathematics instruction accurately. With hypermedia, text, graphics, audio, animation and video are linked through hyperlinks. Hypermedia provides a powerful option to combine curriculum content with instructional aides, thereby meeting the diverse needs of students.
