Correlational analysis of two years of classroom observation indicates relationships between technology use and various classroom characteristics, including teacher roles and instructional strategies. Three observers used the ISTE Classroom Observation Tool (ICOT) to record 144 observations of classrooms participating in a variety of educational technology grant programs in the United States. The findings suggest that decision makers consider the instructional implications and possible unintended consequences of implementing different information and communication technologies.
