This report details the development of a learning progression for the understanding of fractions. The intended use of the learning progression is to support formative assessment practices for children as they receive instruction during elementary school. The validity of the learning progression is evaluated by mapping its levels to vertically scaled test items answered by students taking Curriculum Associates' i-Ready Diagnostic Assessment. It is shown that there is a significant moderate correlation between the levels of the learning progression and the difficulty of the test items associated with each level.

This document presents a set of classroom assessment principles intended as a resource for practitioners, especially school leaders and district and state policymakers. Together these principles articulate a shared vision for effective classroom assessment practices.

By the ASPIRE Research Team. This paper outlines development of the Modeling Energy Flows Learning Progression and key indicators for each level of the learning progression. This learning progression is designed to directly support three-dimensional science learning by integrating the crosscutting concept of energy in systems and the science practice of modeling at each level.
