O'Rear, Connor D.; Zippert, Erica L.; Ehrman, Patrick; Westerberg, Lauren; Lonigan, Christopher J.; Purpura, David J. – Infant and Child Development, 2023
In two studies, we investigated whether using three-dimensional (3D) manipulatives during assessment aided performance on a variety of preschool mathematics tasks compared to pictorial representations. On measures of children's understanding of counting and cardinality (n = 103), there was no difference in performance between manipulatives and…

Litkowski, Ellen C.; Duncan, Robert J.; Logan, Jessica A. R.; Purpura, David J. – AERA Open, 2020
The current study examined preschoolers' (N = 801) age-related performance on one measure of verbal counting and two measures of cardinality ("how many" and "give n") aligned with the kindergarten Common Core State Standards for Mathematics (CCSSM) and included in the majority of states' early learning guidelines for…

Purpura, David J.; Reid, Erin E.; Eiland, Michael D.; Baroody, Arthur J. – School Psychology Review, 2015
A critical component in enhancing academic success is identifying children at risk of later academic difficulties. Although significant efforts have been devoted to design effective assessment processes in elementary school, fewer efforts (particularly for mathematics) have been made for preschool. The focus of this study was to design and…

Schmitt, Sara A.; Geldhof, G. John; Purpura, David J.; Duncan, Robert; McClelland, Megan M. – Journal of Educational Psychology, 2017
The present study explored the bidirectional and longitudinal associations between executive function (EF) and early academic skills (math and literacy) across 4 waves of measurement during the transition from preschool to kindergarten using 2 complementary analytical approaches: cross-lagged panel modeling and latent growth curve modeling (LCGM).…

Baroody, Arthur J.; Eiland, Michael D.; Purpura, David J.; Reid, Erin E. – American Educational Research Journal, 2013
In a 9-month training experiment, 64 first graders with a risk factor were randomly assigned to computer-assisted structured discovery of the add-1 rule (e.g., the sum of 7 + 1 is the number after "seven" when we count), unstructured discovery learning of this regularity, or an active-control group. Planned contrasts revealed that the…
