The Smart Board is an interactive whiteboard system that includes a computer, projector, and software. It allows users to control the computer by touching the board like a touchscreen. Some key features include digital ink, infinite cloning, capturing and annotating areas of the screen, and recording lessons. Using a Smart Board in teaching provides benefits like encouraging student engagement, supporting visual learning styles, and improving communication for students with disabilities. However, Smart Boards can be expensive and sometimes difficult to use.
