Title: The Role of Mediators in the Development of Longitudinal Mathematics Achievement Associations. Author: Watts TW, Duncan GJ, Chen M, Claessens A, Davis-Kean PE, Duckworth K, Engel M, Siegler R, Susperreguy MI. Journal: Child Dev; 2015; 86(6):1892-907. PubMed ID: 26332124. Abstract: Despite research demonstrating a strong association between early and later mathematics achievement, few studies have investigated mediators of this association. Using longitudinal data (n = 1,362), this study tested the extent to which mathematics self-concepts, school placement, executive functioning, and proficiency in fractions and division account for the association between mathematics achievement in first grade and at age 15. As hypothesized, a strong longitudinal association between first-grade and adolescent mathematics achievement was present (β = .36) even after controlling for a host of background characteristics, including cognitive skills and reading ability. The mediators accounted for 39% of this association, with mathematics self-concept, gifted and talented placement, and knowledge of fractions and division serving as significant mediators.[Abstract] [Full Text] [Related] [New Search]
