The lesson guide Instructional Goals section states the intended purposes and the general concepts of the video. This section helps you prepare to make the showing a meaningful learning experience. You know your stuff. You also know what the audience needs to know about your subject. And you have a time frame in which to get your message across.
Videos have many different purposes and affect students differently.
Some studies indicate that it is not always desirable to stop a production during the showing, as the continuity of the story is broken. However, good teachers have learned to be in front of the classroom where reactions of students are observed and questions are answered. Teachers often point directly to the screen, interpreting captions of the visual to allow for association with corresponding signs. Key vocabulary is discussed in context. Certain segments of the video can be paused and discussed immediately, rather than waiting until the end of the production.
