The document summarizes research from the Marzano Research Lab on using interactive whiteboards and clicker devices to enhance instruction and assessment. The research found that using interactive whiteboards was associated with an average 16 percentile point gain in student achievement. When used by an experienced teacher with extensive training who used the board 75% of the time, achievement gains increased to an impressive 29 percentiles. However, the technologies were only effective when supported by good instructional practices like individualizing instruction, collaborative work, engaging content, and using data to improve. Simply using the technologies without addressing quality or ongoing training provided no benefits and sometimes harmed achievement.
