About DVAction and frequently asked questions (FAQ)
DVAction is a database of digital video and images comprised of techniques and equipment used in the general chemistry laboratory. It is a free resource designed for instructors to aid in the development of multimedia materials for their courses. Instructors can quickly link to any video segment or image (called objects) within the database or easily copy an object from the database into their own materials. The database is ideally suited for the creation of multimedia lecture presentations and online laboratory manuals and quizzes.
Flexibility was one of the key issues in the design of this database. Video techniques are divided into stand-alone segments so that instructors can choose to view a technique in its entirety or view a segment within a technique. For example, if instructors wish to focus on what happens at the endpoint of a titration, they do not have to show the entire titration. They can simply select the segment containing the endpoint. This allows for the creation of materials tailored to a specific need. The video objects also come with voice-over and text. Instructors can choose to use both these features, one of these features, or none of these features. For example, voice-over may be advantageous for an on-line laboratory manual; however, a lecturer may want to provide his or her own narration for a video presentation. Finally, there is flexibility in the way the objects are accessed. Instructors can link directly to an object in the database, or they can download objects to their computer or website. The method used to access the objects will depend to some extent on the application, disk space, and network speed.
Instructors may use DVAction in any creative way they choose. However, all objects within the database remain the property of the DVAction Project and the Committee for Institutional Cooperation. Instructors should take all appropriate steps to attribute credit. See complete Copyright statement.
