One traditional audio media is the audiocassette. It is a simple, inexpensive way for students to record information presented in a class so they can listen to it later. Another traditional audio media is the CD. The book gives several reasons for why CD's are slightly more convenient to use than audiocassettes. You can randomly access a CD in the middle, rather than searching a tape to find specific information, and CDs are much more durable as well. However, both of these devices are good ways for those you are audio learners to better learn class material.
Two new audio technologies are the MP3 player and Internet radio. According to the book, "whether using with a data project unit for a whole class activity or with a single computer for an individual or small-group project, Internet radio broadcasts offer fascinating possibilities to creative teachers." The MP3 player can be used also. Educational materials can be downloaded and listened to in the classroom.
Some traditional visual technologies are the bulletin board and overhead projectors. A bulletin board can easily be used in a classroom to hang or present materials and can easily be changed. An overhead projector can be used to present a lesson plan. to a class and transparencies can be easily created by teachers and they are an easy way to present.
Two emerging technologies are the DVD and the video chatting. DVDs are good storage devices and a lesson can be recorded on the DVD than the student could watch and listen to the lesson over again. Video chatting is also a great technology. If a teacher can't be in a classroom for some reason they can video stream themself in over the internet. Kids can also watch a lesson happening in another room potentially if another teacher had something they wanted to share with another room.
