After showing the students the meandering stream, a teacher could have them describe what they saw. The picture tied with the discussion would be a powerful technique in helping them develop this idea. The images available on the Web can bring real meaning into the classroom. Here the World Wide Web offered visuals not available on other media. Children of today see video all around them.
Video can capture the attention of many learners.
Therefore, videos can be extremely powerful. Videos can help set a context as well as allow students to visualize phenomena that would be too dangerous or difficult to observe through real life experiences. Videos can also be used to raise issues or enhance many of the ideas teachers are trying to capture in a project. Although we don't want to encourage the incessant use of video, the judicial use of video can have many beneficial educational outcomes. Videos can be used to help set the context of a project, or they can be used to enhance the context.
