In the second edition of "Data-Driven Dialogue: A Facilitator's Guide to Collaborative Inquiry," authors Bruce Wellman and Laura Lipton provide strategies that transform school culture through data-driven inquiry. By applying a three-phase model and a host of process tools to facilitate collaborative data analysis, K-12 school and district leaders can develop high-performing teams, promote effective problem solving, and orchestrate decisions that stay made. K-12 school leaders will: (1) Develop facilitative skills in orchestrating data-driven dialogue; (2) Access the Collaborative Learning Cycle, an inquiry-driven model for structuring data-driven planning and problem solving; (3) Learn how to create visually vibrant data displays; (4) Explore tools for teams, along with information on application, variation, and extension; and (5) Utilize an appendix that includes a glossary of technical terms, a rubric for group assessment and goal setting, additional strategy descriptions, examples of survey questions, and planning designs for meetings.
