Direct linkTorbeyns, Joke; Verschaffel, Lieven; Ghesquiere, Pol – Cognition and Instruction, 2006
The aim of the study was to analyze the development of children's adaptive expertise in computing sums and differences up to 100. We defined the adaptive nature of children's strategy choices on the basis of problem (addition, subtraction), achievement, and strategy performance (accuracy, speed). Sixty-nine 2nd graders of high, above-average, or…

Peer reviewedRabinowitz, Mitchell; Woolley, Kenneth E. – Cognition and Instruction, 1995
Examines the hypothesis that problem comprehension and computational processes interact during the solving of arithmetic word problems. Results suggest the absence of any interaction between the two processes. Questions the notion that automatized retrieval facilitates problem solving, as well as assertions suggesting that increasing computational…
