This article provides a validation framework for research on the development and use of science Learning Progressions (LPs). The framework describes how evidence from various sources can be used to establish an interpretive argument and a validity argument at five stages of LP research--development, scoring, generalisation, extrapolation, and use.…

Children with disabilities demonstrate fewer complex pretend play behaviors than children with typical development, which might limit their social participation in early childhood settings. A multiple-probe design was used to examine the relation between a single prompt procedure--constant time delay--and the acquisition, maintenance, and…

Background: Analogical mapping is a domain-general cognitive process used notably in language development, and particularly in the abstraction of construction schemas. Children with developmental language disorders (DLD) display an impairment in linguistic productivity and creativity, which can be linked to a lack of generalization of construction…

In this article we advance characterizations of and supports for elementary students' progress in generalizing and representing functional relationships as part of a comprehensive approach to early algebra. Our learning progressions approach to early algebra research involves the coordination of a curricular framework and progression, an…
