A formative pilot study of a fractions intervention was conducted to address the intervention's potential for improving fifth-grade struggling students' knowledge of fractions, and to identify any logistical or instructional design issues, before scaling up for a randomized control trial. In the first section, we provide details of the formative…

The purpose of this study was to explore the efficacy of fractions intervention with and without an embedded self-regulation (SR) component for third-grade students at risk for mathematics disabilities. Fractions intervention focused on magnitude understanding and word problems. Embedded SR was designed to support a growth mindset (fostering…

Peer reviewedSophian, Catherine; Garyantes, Danielle; Chang, Chuan – Developmental Psychology, 1997
Four experiments examined children's understanding of the inverse relationship between the number of parts into which a quantity is divided and the size of each part. Found that children tended to judge that bigger shares resulted from sharing with more recipients. Seven-year olds performed correctly on a simplified equal-sharing task. Five-year…

Peer reviewedKeijzer, Ronald; Terwel, Jan – Learning and Instruction, 2003
Studied the teaching and learning of fractions in two matched groups of 10 9-10-year-olds in the Netherlands. In the experimental group, fractions were introduced using the bar and number line as mental models, while the control group used fair sharing and the circle model. The experimental group showed more proficiency in fractions after 1 year.…

Cramer, Kathleen; Post, Thomas – 1995
At issue in this study was the extent to which large numbers of classroom teachers were able to implement research-based materials with a minimum of inservice education. Also at issue was whether students of these teachers were able to develop the rich mental images for fractions similar to the ones students from previous Rational Number Project…

Peer reviewedCramer, Kathleen A.; Post, Thomas R.; delMas, Robert C. – Journal for Research in Mathematics Education, 2002
Contrasts student achievement using commercial curricula (CC) for initial fraction learning with that of using the Rational Number Project (RNP) fraction curriculum. Indicates that students using RNP materials had statistically higher mean scores on concepts, order, transfer, and estimation. Interview data showed differences in the quality of…
