Our paper is an analytical review of the design, development and reporting of learning
progressions and teaching sequences. Research questions are:(1) what criteria are being …

This article reports results from a study investigating the impact of a sustained,
comprehensive early algebra intervention in third grade. Participants included 106 students; …

In this chapter, we discus s the algebra framework that guides our work and how this
framework was enacted in the design of a curricular approach for systematically develo** …

In this article we advance characterizations of and supports for elementary students'
progress in generalizing and representing functional relationships as part of a …

A cluster randomized trial design was used to examine the effectiveness of a Grades 3 to 5
early algebra intervention with a diverse student population. Forty-six schools in three …

We share here results from a quasi-experimental study that examines growth in students'
algebraic thinking practices of generalizing and representing generalizations, particularly …

Learning progressions have been demarcated by some for science education, or only
concerned with levels of sophistication in student thinking as determined by logical analyses …

A learning progression is a road map that shows how a student's qualitative understanding
of particular ideas or practices is likely to change with appropriate instruction. An important …

The aim of the study is to investigate and compare approaches to algebra in the Estonian,
Finnish, and Swedish national core curricula (Grades 1–9). Despite the similarities in the …

In the spirit of model revision, researchers continue to refine the notion of a learning
progression. Despite many advances in learning progressions research, one key design …
