Spatial thinking is an important predictor of mathematics. However, existing data do not determine whether all spatial sub‐domains are equally important for mathematics outcomes nor whether mathematics–spatial associations vary through development. This study addresses these questions by exploring the developmental relations between mathematics and spatial skills in children aged 6–10 years (N = 155). We extend previous findings by assessing and comparing performance across Uttal et al.'s (2013), four spatial sub‐domains. Overall spatial skills explained 5%–14% of the variation across three mathematics performance measures (standardized mathematics skills, approximate number sense and number line estimation skills), beyond other known predictors of mathematics including vocabulary and gender. Spatial scaling (extrinsic‐static sub‐domain) was a significant predictor of all mathematics outcomes, across all ages, highlighting its importance for mathematics in middle childhood. Other spatial sub‐domains were differentially associated with mathematics in a task‐ and age‐dependent manner. Mental rotation (intrinsic‐dynamic skills) was a significant predictor of mathematics at 6 and 7 years only which suggests that at approximately 8 years of age there is a transition period regarding the spatial skills that are important for mathematics. Taken together, the results support the investigation of spatial training, particularly targeting spatial scaling, as a means of improving both spatial and mathematical thinking.

BackgroundPrior longitudinal and correlational research with adults and adolescents indicates that spatial ability is a predictor of science learning and achievement. However, there is little research to date with primary‐school aged children that addresses this relationship. Understanding this association has the potential to inform curriculum design and support the development of early interventions.AimsThis study examined the relationship between primary‐school children's spatial skills and their science achievement.MethodChildren aged 7–11 years (N = 123) completed a battery of five spatial tasks, based on a model of spatial ability in which skills fall along two dimensions: intrinsic–extrinsic; static–dynamic. Participants also completed a curriculum‐based science assessment.ResultsControlling for verbal ability and age, mental folding (intrinsic–dynamic spatial ability), and spatial scaling (extrinsic–static spatial ability) each emerged as unique predictors of overall science scores, with mental folding a stronger predictor than spatial scaling. These spatial skills combined accounted for 8% of the variance in science scores. When considered by scientific discipline, mental folding uniquely predicted both physics and biology scores, and spatial scaling accounted for additional variance in biology and variance in chemistry scores. The children's embedded figures task (intrinsic–static spatial ability) only accounted for variance in chemistry scores. The patterns of association were consistent across the age range.ConclusionSpatial skills, particularly mental folding, spatial scaling, and disembedding, are predictive of 7‐ to 11‐year‐olds’ science achievement. These skills make a similar contribution to performance for each age group.

Mobile touchscreen applications present new opportunities for children's language learning. This systematic review synthesizes the evidence on the impact of features of mobile applications on children's language learning. Experimental studies published from 2010 onwards with children aged 3 to 11 years old were included. Of the 1,081 studies screened, 11 studies were identified, which examined four features of mobile touchscreen applications: inbuilt narration, real-time conversation prompts, augmented reality (AR), and hotspots. Inbuilt narration had a positive impact on story comprehension and word learning compared to reading alone but not shared reading with an adult. Real-time conversation prompts improved the quality and quantity of adult-child talk, and AR supported language learning ostensibly via increased motivation. No evidence was found for an impact of text-relevant hotspots. Limitations of the existing literature are discussed, and a strong case is made for further research in the area, particularly that which builds on learning theory and existing qualitative research.New technologies can provide new opportunities for gaining language and literacy skills for adults and children. The field of Mobile Assisted Language Learning (MALL) has generated promising insights on language learning using digital technologies for adult learners (Lin & Lin, 2019;Sung, Chang, & Yang, 2015), and emerging research on mobile, touchscreen devices such as tablets and smartphones with adults and children suggests that these now ubiquitous tools can support language skills too (Godwin-Jones, 2017;Neumann & Neumann, 2017). Looking beyond questions of whether such technologies can support learning, new empirical research is exploring how, by examining which specific features of mobile touchscreen devices have an impact on language learning (Jin,

The multidimensional structure of spatial ability remains a debated issue. However, the developmental trajectories of spatial skills have yet to be investigated as a source of evidence within this debate. We tested the intrinsic vs. extrinsic and static vs. dynamic dimensions of the Uttal et al. (2013) typology in relation to spatial development. Participants (N = 184) aged 6-11 completed spatial tasks chosen to measure these spatial dimensions. The results indicated that the developmental trajectories of intrinsic vs extrinsic skills differed significantly. Intrinsic skills improved more between 6 and 8 years, and 7 and 8 years, than extrinsic skills. Extrinsic skills increased more between 8 and 10 years than intrinsic skills. The trajectories of static vs. dynamic skills did not differ significantly. The findings support the intrinsic vs. extrinsic, but not the static vs. dynamic dimension, of the Uttal et al. (2013) typology.

(2013) model proposes that spatial thinking is comprised of two dimensions.There is a scarcity of developmental findings assessing the validity of these dimensions. What does this study add?The developmental trajectories of intrinsic versus extrinsic skills differ significantly. The developmental trajectories of static versus dynamic skills do not differ significantly. Spatial skill developmental trajectories support the intrinsic versus extrinsic dimension only.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Polysemy, or the property of words having multiple meanings, is a prevalent feature of vocabulary. In this study we validated a new measure of polysemy knowledge for children with English as an additional language (EAL) and a first language (EL1) and examined the relationship between polysemy knowledge and age, language status, and reading comprehension. Participants were 112 British children aged 5 to 6 (n = 61) or 8 to 9 years (n = 51), 37% of whom had EAL (n = 41). Participants completed the new measure of knowledge of polysemes, along with other measures of language, literacy and cognitive ability. The new measure was reliable and valid with EAL and EL1 children. Age and language status predicted children's polyseme knowledge. Polyseme knowledge uniquely contributed to reading comprehension after controlling for age, language status, non-verbal intelligence, time reading in English, and breadth of vocabulary. This research underscores the importance of polysemy for children's linguistic development.
