This chapter describes the 22 components of professional practice within the framework of the 4 domains. Each description has three parts: Rationale and Explanation, Demonstration, and a figure showing the elements of the component and how the four levels of performance (Unsatisfactory, Basic, Proficient, and Distinguished) apply to each element.
Domain 1 describes the critical, behind-the-scenes work of organizing for classroom instruction. Even in schools or districts with an established curriculum, teachers put considerable effort into transforming that curriculum so it is accessible to their students. That effort includes having a deep knowledge of the content itself and designing instruction that is appropriate to the diverse learners in one's charge.
