The widespread adoption of more rigorous state guidelines for student learning, such as the Common Core State Standards (CCSS), has led to tremendous interest in how best to prepare and develop teachers to foster the skills that students need to meet the new standards and succeed in college and careers. A promising pathway is to combine quality curriculum and professional learning so that teachers’ instructional practices are directly aligned with the content they are teaching. While the emerging research suggests the need to integrate teachers’ knowledge and skill development with instructional materials, further evidence is necessary to support the effectiveness of such an approach.
