This report focuses on learning trajectories for mathematics education; what they are (including defining various ways in which the terms trajectory, progression, learning, and teaching are used); and how they can function to inform instruction. The report provides examples from the Common Core States Standards (CCSS) that help to illustrate points about learning trajectories.
This lengthy report provides a valuable context for learning trajectories for mathematics education and their importance in instructional practices. The report focuses on a variety of related topics, such as curriculum development, assessment and formative assessment practice, and development of instructional pedagogy. The report specifically addresses mathematics instruction, but it may be relevant to educators and researchers in other content areas who are considering using learning trajectories.
