Generating Scenarios of Addition and Subtraction: A Study of Japanese University Students
Peer reviewed Peer reviewed
Direct linkDirect link
Kinda, Shigehiro – Journal of Mathematical Behavior, 2013
Students are presented with problems involving three scenario types of addition and subtraction in elementary mathematics: one dynamic ("Change") and two static ("Combine, Compare"). Previous studies have indicated that the dynamic type is easier for school children, whereas the static types are more difficult and comprehended only gradually…

Teaching Children to Add and Subtract.
Peer reviewed Peer reviewed
Gutstein, Eric; Romberg, Thomas A. – Journal of Mathematical Behavior, 1995
Reviews research using diagrams, number sentences, and algorithms to help students learn to add and subtract; poses questions on the relationship of instruction to children's knowledge construction; and proposes a research agenda in this area. (86 references) (MKR)

An Assessment of the Processing Load of Some Strategies and Representations for Subtraction Used by Teachers and Young Children.
Peer reviewed Peer reviewed
Boulton-Lewis, Gillian M. – Journal of Mathematical Behavior, 1993
Describes research which compared the processing loads of mathematical representations and strategies used by (n=3) teachers and (n=29) children aged 5-8 for interpreting subtraction operations represented in numerical form. Some representations and strategies appeared to impose an extra processing load which can interfere with conceptual…
