How Eighth-Grade Students Estimate with Fractions
… focused on strategies used for estimating with whole numbers and decimals while neglecting those used for fractions. An extensive literature review revealed one study specifically directed toward estimating with fractions (Hanson & Hogan, 2000) that researched adult estimation strategies and not …

A study of Grade 8 and 9 learner thinking about linear equations, from a commognitive perspective
… and that learners favour working with whole numbers, even when the context is negative integers or algebraic terms. Furthermore, they do not make a link between the solution of the equation and the function. As a result they have limited flexibility to adapt their routines.

Combinatorial number theory through diagramming and gesture
… theory, we study a variety of problems about whole numbers that include enumerative, diagrammatic, or computational elements. We present results motivated by two different areas within combinatorial number theory: the study of partitions and the study of digital representations of integers. We …

Children's Understanding of the Uses of Parentheses
"Parentheses can be used in the context of whole numbers, fractions, decimals, integers (which include negative values), or algebra in four different ways: to represent the associative property (e.g., (5 + 3) + 2 = 5 + (3 + 2)), to represent the distributive property (e.g., 5 x (3 + 2) = 5 x 3 + 5 …

POSIT: Process Oriented Subtraction-Interface for Tutoring
… the tutoring of a cognitive skill-subtraction of whole-numbers. Because ACT* theory explicitly describes the interaction of declarative and procedural knowledge (procedural knowledge is dependent on declarative knowledge), this learning theory is ideally suited to the learning of a specific …
