The Culture of Data Use Workshop Toolkit helps school and district teams apply research to practice as they establish and support a culture of data use in their educational setting. The field-tested workshop toolkit guides teams through a set of structured activities to develop an understanding of data-use research in schools and to analyze examples from practice. Teams learn to apply these concepts to enhance their own culture of data use and outline effective next steps. The conceptual framework of the toolkit draws on five research-based elements known to support an effective culture of data use, and supporting materials--a facilitator's guide and agenda, a slide deck, and participant handouts--provide workshop facilitators with all the necessary materials to lead this process in their own setting.
