One of the pillars of the educational reform movement is curriculum. The curriculum needs to meet two goals: (1) Students need the breadth and depth of content knowledge not just facts for tests (2) But students also need to be taught what they need to know to pass high-stakes tests. Rigorous Curriculum Design is straightforward, sequential and explicit in presenting a step-by-step process educators/curriculum designers can follow to create units of study in any grade, course or content area that answers both these goals.
