Dr. Doabler and his collaborators recently published “Promoting understanding of measurement and statistical investigation among second-grade students with mathematics difficulties” in the Journal of Educational Psychology.
This study investigated whether a second-grade mathematics intervention improved the mathematics achievement of 130 second-grade students who were at risk for long-term difficulties in mathematics. The Precision Mathematics Grade 2 intervention contains 32 lessons focused on foundational concepts of early measurement and data.
Results indicated the intervention had positive effects on an early mathematics assessment. Students with higher mathematics skills at the start of the study were also found to receive the most benefit from the intervention. These findings suggest providing instruction in the areas of measurement and data may be important for supporting the mathematical learning of at-risk learners.
