"The interactive nature of the SMART Board provides many practical uses for the classroom. Using SMART Notebook software, teachers can record each step of a lesson for students to review.
The flexibility of use in the classroom, including the multiple ways in which teachers can display information (interactive text, images, sound and video files), has been shown to facilitate ESL instruction and support both differentiated learning and universal design for learning (UDL).
Research indicates that use of an interactive white board in the classroom can be an effective means of decreasing teacher stress. Recent research also suggests that the direct interaction with a touch-sensitive display makes use of natural, intuitive movements which allows students as young as preschool to easily use a SMART Board.
Furthermore, the size of the display screen has been shown to assist in the education of visually impaired students while the addition of a classroom amplification system has been proven to benefit deaf and hard of hearing students." wikipedia link up above
