The document discusses interactive whiteboards and their uses and benefits in the classroom. Interactive whiteboards are large touch screens connected to a projector and computer that allow users to manipulate projected images. They can be used to reinforce concepts through games, emphasize information in presentations, take notes directly on presentations, and project e-books. Key benefits include increased student engagement, interactivity, and support for different learning styles. However, drawbacks include high costs, need for teacher training, and technical issues like boards needing realignment or projection being obscured.
