Abstract
Curriculum materials that support learners in building and linking ideas are essential in developing integrated understanding. We refer to such materials as coherent. There are several types of curricular coherence – content standard, learning goal, intra-unit, and interunit coherence. Learning progressions, which are descriptions of successively more sophisticated ways of thinking about how learners develop understanding of key disciplinary concepts and practices within and across multiple grades, can help designers build coherent curriculum. Learning progressions can align standards, curriculum, and assessments across grades and grade bands. This chapter describes the different types of coherence and discusses the role that learning progressions play in the design and development of coherent curriculum materials, and why coherent materials are critical in supporting students in building integrated understanding.
