The Learning Progression Explorer is an online tool that allows users to explore learning progressions in reading and mathematics. A learning progression describes what it typically looks like for learners to move from early knowledge, skills and understandings to more advanced knowledge, skills and understandings within a domain. Learning progressions conceptualize, organize and describe learning domains with reference to core concepts/practices that are present in basic forms in early learners, and become increasingly abstract, generative or sophisticated as learning progresses. Learning progressions are developed from empirical evidence of typical sequences of learning progress, and from theoretical understandings of the nature of progress (e.g. logical prerequisites for learning). They also are influenced by curriculum conventions and intentions (e.g. sequences in which material is commonly introduced), and informed by the experiences, observations and practices of teachers.
