Feedback from teachers goes a long way in reaffirming the value addition of educational DVDs. Biology teachers for instance, find the lessons on Cells, Fertilization and Photosynthesis to be well illustrated, with the graphics and explanations most appropriate for students. Geography is another subject which middle-school students find fascinating as they work on key concepts like rotation and revolution of the Earth; the 3-D effects and graphics makes the subject come alive and students are able to see on the screen how the Earth rotates and revolves. Due to the 3-D visualization with graphics and narration these contents get maximum attention from the students.
