Profiles of fraction knowledge in first grade and their relation to cognitive and mathematical skills
Latent profile analysis was used to examine variation in early fraction knowledge among first graders (N = 204; Mage = 6.68 years) across nonsymbolic and symbolic representations. Three distinct profiles of fraction understanding emerged. Profile 1 exhibited strong nonsymbolic knowledge, Profile 2 demonstrated similarly strong knowledge, except for weaker performance in nonsymbolic equivalence, and Profile 3 showed generally limited understanding across most areas. However, by the end of first grade, children initially identified as Profile 2 performed comparably to those in Profile 1 on measures of equivalence. Additionally, children in both Profiles 1 and 2 showed stronger cognitive skills and higher year-end mathematics achievement than those in Profile 3. These findings suggest that understanding of nonsymbolic equivalence may develop over the course of first grade in children who otherwise demonstrate strong foundational fraction knowledge, so that an initial relative weakness in that area is not concerning.
期刊介绍:
Learning and Individual Differences is a research journal devoted to publishing articles of individual differences as they relate to learning within an educational context. The Journal focuses on original empirical studies of high theoretical and methodological rigor that that make a substantial scientific contribution. Learning and Individual Differences publishes original research. Manuscripts should be no longer than 7500 words of primary text (not including tables, figures, references).
