Darius Endlich; Wolfgang Lenhard; Peter Marx; Tobias Richter – Journal of Learning Disabilities, 2024
Children with mathematical difficulties need to spend more time than typically achieving children on solving even simple equations. Since these tasks already require a larger share of their cognitive resources, additional demands imposed by the need to switch between tasks may lead to a greater decline of performance in children with mathematical…

Vasilyeva, Marina; Laski, Elida V.; Shen, Chen – Developmental Psychology, 2015
The present study tested the hypothesis that children's fluency with basic number facts and knowledge of computational strategies, derived from early arithmetic experience, predicts their performance on complex arithmetic problems. First-grade students from United States and Taiwan (N = 152, mean age: 7.3 years) were presented with problems that…

Cawley, John F.; Shepard, Teri; Smith, Maureen; Parmar, Rene S. – Learning Disabilities: A Multidisciplinary Journal, 1997
The performance of 76 students (ages 10 to 15) with learning disabilities on four tasks of arithmetic computation within each of the four basic operations was examined. Tasks varied in difficulty level and number of strokes needed to complete all items. Intercorrelations between task sets and operations were examined as was the use of…

Usnick, Virginia – Focus on Learning Problems in Mathematics, 1988
The study investigated which addition facts children and preservice teachers view as being difficult, whether it is possible to determine facts which are difficult for all children, and whether children and adults agree on which facts are difficult. Results indicated that children and adults disagree about the difficulty of facts. (PK)
