The more interested and engaged students are, and the more interactive each learning session is, the more students will enjoy, learn from and retain information from the lesson.
Video provides a means of interactive instruction and is a very flexible medium. Having the ability to stop, start and rewind is absolutely invaluable. It provides the option to stop each video and challenge students to predict the outcome of a demonstration, and elaborate on, or debate a point of historical reference. You also have the option to rewind a section of the video to review a segment to ensure that children understand a key concept. You can ensure to add further interactivity by copying activities, conducting discussions or repeating demonstrations and experiments in the your classroom.
