In So What Do They Really Know? Cris Tovani explores the complex issue of monitoring, assessing, and grading students' thinking and performance with fairness and fidelity. Like all teachers, Cris struggles to balance her student-centered instruction with school system mandates. Her recommendations are realistic and practical; she understands that what isn't manageable isn't sustainable. Cris describes the systems and structure she uses in her own classroom and shows teachers how to use assessments to monitor student growth and provide targeted feedback that enables students to master content goals. She also shares ways to bring students into the assessment cycle so they can monitor their own learning, maximizing motivation and engagement.
