M.; Dionne, Ginette; Brendgen, Mara; Vitaro, Frank; Tremblay, Richard E.; Boivin, Michel; Kovas, Yulia – British Journal of Educational Psychology, 2019
Background: The number line task assesses the ability to estimate numerical magnitudes. People vary greatly in this ability, and this variability has been previously associated with mathematical skills. However, the sources of individual differences in number line estimation and its association with mathematics are not fully understood. Aims: This…

Xu, Chang; Lafay, Anne; Douglas, Heather; Di Lonardo Burr, Sabrina; LeFevre, Jo-Anne; Osana, Helena P.; Skwarchuk, Sheri-Lynn; Wylie, Judith; Simms, Victoria; Maloney, Erin A. – Journal of Educational Psychology, 2022
Language skills play an important role in mathematics development. Students (7 to 10 years of age) learning school mathematics either in the same language used at home (first-language learners; n = 103) or in a different language (second-language learners; n = 57) participated in the study. Relations among cognitive skills (i.e., receptive…

Xu, Chang; Wells, Emma; LeFevre, Jo-Anne; Imbo, Ineke – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2014
The purpose of the present study was to examine factors that influence strategic flexibility in computational estimation for Chinese- and Canadian-educated adults. Strategic flexibility was operationalized as the percentage of trials on which participants chose the problem-based procedure that best balanced proximity to the correct answer with…

The Importance of Shifts in Language Level and Extraneous Information in Determining Word Problem Difficulty: Steps toward Individual Assessment.
Bachor, Dan G. – Diagnostique, 1989
Urban Canadian sixth-graders (n=84) were tested on 80 arithmetic word problems developed as part of a larger set to reflect individual differences in problem solving. Problems varied in complexity of language and amount of extraneous information present. Results indicated substantial internal consistency and concurrent validity relative to…
