Repository record for a peer-reviewed article (the page states "Article révisé par les pairs") in Learning and Instruction, volume 20, issue 6, pages 521-532, published 2009-07-04. The only substantive content available is the title, which names the phenomenon: "Developmental changes in the comparison of decimal fractions". No abstract, method, or results text is printed on the record, so no effect size or sample information is available.

"Developmental changes in the comparison of decimal fractions"

Discussion¶

Learner Variables¶

• Operations and Place Value — outcome: instruction changes it
• Proportional Reasoning — outcome: instruction changes it

Related Claims¶

• Visual fraction models yield more accurate magnitude comparisons than Arabic numeral fractions for all ability groups, but the visual model advantage persists through Grade 8 only for children with MLD — related
• Place value label use correlates with accuracy on fraction-decimal equivalency items — related
• Fraction pairs with common denominators are compared more accurately than pairs with common numerators, but children with MLD show a crossover, improving on common numerator items while declining on common denominator items — related
• The one-half advantage in fraction comparison emerges by Grade 4 for TA children and Grade 5 for LA children, but only at Grade 7 for children with MLD, who never exceed ~75% accuracy on one-half items — related
• Most preservice teachers were overconfident in the completeness of their fraction comparison explanations at both first draft and revision — related
