Why Use DVD Technology?

DVD-ROMs offer the ability to view content and solve problems in a non-linear manner, as well as to explore topics from multiple perspectives.
DVD-ROMs offer rich audio and video capabilities and provide dynamic interactive navigation and searching features that allow for nonlinear access to content. After all, students' minds rarely move in a linear path! Teachers and students are able to explore topics from multiple perspectives. Teachers can use as much of a lesson as desired, moving through it at their own pace. They can quickly navigate to the 2- or 10- or 20-minute segment they want to share, instead of having to fast-forward and rewind a videotape--saving valuable instructional time. Similarly, students can jump to specific relevant pieces of information as they question and explore a topic. Instead of reading a document or viewing a video in a more traditional, linear manner, they not only can but are encouraged to create their own uniquely personal pathways through educational content.

Any classroom resource that allows students to visualize the content they are studying is a valuable tool for learning. Index-able DVD-ROMs strengthen the power of the resource by letting teachers easily align the electronic content to lesson objectives. At the same time, students are able to break down the topic and investigate the content in a variety of sequences and from a host of vantage points--gaining an enhanced perspective similar to what might be learned from watching a basketball game with the replays and commentary on TV, as opposed to simply watching the event in person from the stands.
DVD-ROM technology provides a "safe" environment with trusted and easy-to-access multimedia resources.
Working with print resources such as encyclopedias can be frustrating for a student engaged in independent research, especially if help is not readily available. Pointing and clicking can be much easier than looking in book after book to try to understand new information. Additionally, since students who are doing independent research are not always sure what they are looking for, an easy, exploration-based mode for investigating appropriate resources can be helpful.
The Internet is another medium that provides access to a variety of rich instructional resources and a wonderful point and click research environment. But the Web also allows access to inappropriate and perhaps controversial information. DVD-ROM resources make such independent research both easier and safer.
A DVD-ROM provides everything in one place.
A DVD-ROM provides access to a vast array of information resources, such as video; maps, charts, or graphs; and primary source documents from multiple sources. The DVD-ROM format not only supplies resources from a variety of media in one place, it also includes links that make it easy for teachers and students to interact with that information. It's unlikely that any teacher would independently have the time to conduct the necessary research to collect such a rich set of resources on a topic; using a DVD-ROM, however, a teacher can easily assemble a personalized set of images, audio, maps and documents -- and can modify them to address students' interests.
