The current wave of science education reforms emphasizes more equitable opportunities for students as they learn disciplinary core ideas and apply crosscutting concepts by engaging in the practices of scientists. Formative assessment—the assessment teachers and students conduct while learning is in progress—also needs to shift to support this vision. This book combines three-dimensional science learning, sociocultural theories of learning, and science for justice and equity to provide a comprehensive picture of formative assessment for today’s K–12 science classroom. Filled with practical examples and strategies, the author provides guidance for classroom teachers around formative assessment task design that centers students’ interests and builds on the resources they bring to school. The text explores the different enactment approaches teachers can use to prioritize and respond to students’ ideas as they are learning. It also offers approaches to, and resources for, professional learning that support teachers as they engage in formative assessment for ambitious science instruction. Book Features: Provides a framework for designing and enacting 3D science assessments that support both rigorous and equitable instruction. Advocates for formative assessment that evaluates the practices of scientific inquiry, as opposed to measuring the memorization of science content.Includes assessment tasks, samples from classroom practice, and transcriptions of classroom conversations with students.Offers guidance for providing students with helpful feedback to advance their learning, as well as suggestions for collaborating with colleagues.Shows how formative assessment can be enacted across classrooms to create opportunities to coordinate practice at a larger scale. “By writing Formative Assessment for 3D Science Learning, Professor Furtak has provided a generous resource for science teachers and school leaders. . . . She lets us see how the theory works. What a wonderful and empowering professional gift.” —From the Foreword by Lorrie A. Shepard, Distinguished Professor Emerita, University of Colorado Boulder
