Interactive whiteboards are used in many schools as replacements for traditional whiteboards or flipcharts. They provide ways to show students any thing which can be presented on a computer's desktop (educational software, web sites, and others). In addition, interactive whiteboards allow teachers to record their instruction and post the material for review by students at a later time. This can be a very effective instructional strategy for students who benefit from repetition, who need to see the material presented again, for students who are absent from school, for struggling learners, and for review for examinations. Brief instructional blocks can be recorded for review by studentsthey will see the exact presentation that occurred in the classroom with the teacher's audio input. This can help transform learning and instruction.
