This 20-minute videotape features 2 schools that have maintained a school culture based on using myriad data sources and processes to fuel their school-improvement activities. In the video the voices of teachers and administrators in each school articulate the ways they have used data to improve student achievement. They highlight numerous data sources, analysis strategies, and actions taken as a result of examining data. A companion booklet is intended to support and extend the utility of the video. Following an introductory section, the next section of the booklet contains descriptions of the schools featured in the video. These two brief summaries provide information helpful in understanding the unique contexts of both schools. The next section contains three group activities intended for use by educators before or after viewing the video. The final section of the booklet contains numerous data resources: books, articles, and websites on data use in schools. In addition, an annotated listing of data tools and services is provided.
