Book excerpt: From distinguished educators, this book imagines what our schools could look like if an authentic vision of the Common Core State Standards (CCSS) were put in place, and thoughtfully critiques how and why implementation has faltered. The authors outline a curriculum framework that focuses on student-based inquiry and the use of formative assessment to monitor and guide student learning. They provide workable, innovative alternatives to the packaged instructional programs and summative tests that have come to be associated with the English language arts (ELA) standards. Vignettes of diverse schools and districts highlight a range of successful approaches to making the CCSS work.
