The goal of this study was to evaluate immediate and delayed effects of a caregiver-implemented picture book intervention to support children's mathematical language and numeracy skills. Eighty-four 3- to 5-year-olds (M[subscript age] = 4.14) were randomly assigned to intervention (n = 40) or active control (n = 44) conditions. Participants in the intervention condition received three researcher-designed picture books with embedded mathematical language content. The active control group received similar books without mathematical language content. All families were asked to read each book a total of four times over 4 weeks (a total of 12 reading sessions). Children were pretested, posttested, and delayed (8 weeks) posttested on mathematical language and numeracy. The intervention resulted in significant positive effects on mathematical language and numeracy at the posttest. At delayed posttest, the mathematical language effects were not statistically significant, but the numeracy effects persisted. However, when only examining the quantitative language items that aligned with the intervention, the effects of the intervention were significant at both immediate and delayed posttests. Findings suggest picture book interventions can have positive impacts on children's early skills.

Prior models suggest that math attitudes and ability might strengthen each other over time in a reciprocal fashion (Ma, 1997). The current study investigated the relationship between math interest and skill both concurrently and over time in a preschool sample. Analyses of concurrent relationships indicated that high levels of interest were related to strong math skills. Even when controlling for initial interest and a brief intelligence measure, math skills predicted math interest approximately 5 months later; in the same way, early interest predicted later skill, even controlling for initial interest. These findings suggest that a reciprocal relationship between math interest and math ability may be in place as early as preschool. (Contains 4 tables and 1 footnote.)

Children's early understanding of mathematics provides a foundation for later success in school. Identifying ways to enhance mathematical instruction is crucial to understanding the ideal ways to promote academic success. Previous work has identified mathematical language (i.e., the words and concepts related to early mathematical development such as more, same, or similar) as a key mechanism that can be targeted to improve children's development of early numeracy skills (e.g., counting, cardinality, and addition). Current recommendations suggest a combination of numeracy instruction and quantitative language instruction to promote numeracy skills. However, there is limited direct support of this recommendation. The goal of the proposed study is to compare the unique and combined effects of each type of instruction on children's numeracy skills in the context of picture book reading. We randomly assigned 234 children (ages 3–5) to one of four conditions where they worked with trained project staff who read picture books targeting: (a) quantitative language only (e.g., more or less), (b) numeracy only (e.g., cardinality, addition), (c) combined [quantitative language + numeracy], or (d) nonnumerical (active control) picture books. Results revealed no significant effects of the quantitative language only or numeracy only conditions, but mixed effects of the combined condition. These findings indicate that more work is needed on how mathematical language and numeracy instruction should best be delivered to preschool children. Educational Impact and Implications Statement: Significant research has highlighted the importance of quantitative language in children's early mathematics development. The findings from this study raise questions as to how to best implement such interventions. Namely, in contrast to prior work, the current interventions targeting one of the two domains did not exhibit positive results. However, mixed effects were found for the condition that combined both domains. Future work on how to best structure combined instruction is needed. [ABSTRACT FROM AUTHOR]
