Blanton, Maria; Stroud, Rena; Stephens, Ana; Gardiner, Angela Murphy; Stylianou, Despina A.; Knuth, Eric; Isler-Baykal, Isil; Strachota, Susanne – American Educational Research Journal, 2019
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 school districts participated. Students in treatment schools were taught the intervention by classroom teachers during regular mathematics instruction. Students in…

Blanton, Maria; Isler-Baykal, Isil; Stroud, Rena; Stephens, Ana; Knuth, Eric; Gardiner, Angela Murphy – Educational Studies in Mathematics, 2019
We share here results from a quasi-experimental study that examines growth in students' algebraic thinking practices of generalizing and representing generalizations, particularly with variable notation, as a result of an early algebra instructional sequence implemented across grades 3--5. Analyses showed that, while there were no significant…

Stephens, Ana; Fonger, Nicole L.; Blanton, Maria; Knuth, Eric – Grantee Submission, 2016
In this paper, we describe our learning progressions approach to early algebra research that involves the coordination of a curricular framework, an instructional sequence, written assessments, and levels of sophistication describing the development of students' thinking. We focus in particular on what we have learning through this approach about…

Fonger, Nicole L.; Stephens, Ana; Blanton, Maria; Knuth, Eric – Grantee Submission, 2015
We detail a learning progressions approach to early algebra research and how existing work around learning progressions and trajectories in mathematics and science education has informed our development of a four-component theoretical framework consisting of: a curricular progression of learning goals across big algebraic ideas; an instructional…
