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. During Showing suggestions in the lesson guide provide ideas for raising questions, predicting outcomes, and other activities for involving students before the end of the video. You can tell them, you can show them, and you can do it for them. But until they tell you, show you, and do it themselves, they have not acquired the knowledge or mastered the skill you want them to learn. Active participation is not just a way of keeping students awake and busy.
