De taak(on)afhankelijkheid en voorspellers van strategieadaptiviteit bij kinderen in rekenen.

Strategy adaptivity, or the ability to select the most efficient strategy on each item, is a key competence for math performance and math development during childhood. Previous findings in arithmetic showed that strategy adaptivity varies with task characteristics and across individuals. However, unknown is whether strategy adaptivity is a task-dependent or task-independent skill. This task-(in)dependency is important for theoretical models of math performance, math development, and children’s strategic behaviors in mathematics and other cognitive domains. This is also an important issue for math education. To address this issue, I will examine individual differences and longitudinal changes in strategy adaptivity using a longitudinal cross-lagged panel design. I will test the predictive value of prior strategy adaptivity, task-specific knowledge, and executive functions on present and later strategy adaptivity while 9- to 13-year-olds accomplish different arithmetic problem-solving tasks.
