The science-specific home learning environment of elementary school children – how are science experiences and science talk associated with the children’s science achievement?

Abstract

ABSTRACT Background The home learning environment (HLE) is central to children’s development. Activities in the HLE are assumed to mediate the effects of distal factors such as family socio-economic status (SES) and parental beliefs and attitudes on children’s development. However, little is known about the science-specific HLE and the relationship between different parent-child science activities and elementary school children’s science learning. Purpose This study aims to investigate a) how different science activities in the HLE relate to children’s science achievement and b) how they mediate the associations of family SES and parents’ beliefs and attitudes on children’s science achievement. Sample Data from the German subsample of the Trends in Mathematics and Science Study (TIMSS) 2019 was analyzed, including 3,437 4th-grade children (Mage = 10.39 years, 50% boys). Design and methods The study has a cross-sectional design. We used structure equation modeling (SEM) to examine associations and test for indirect effects. Results We identified two different patterns of science activities in the HLE: science experiences (e.g. reading science books, experimenting) and science talk. SEM revealed that science talk was associated with children’s science achievement, whereas science experiences were not. Further, science talk mediated associations of family SES and parental beliefs and attitudes on the children’s science achievement. Conclusions Our results might indicate that discursive elements in science activities, such as parent-child science talk, are crucial for children’s science learning, whereas a mere provision of science experiences may not adequately foster the children. We suggest that future research should focus on analyzing the quality of parent-child interactions in different science activities to understand possible learning processes in these activities better. Overall, although effect sizes were small, our results emphasize the crucial role of the HLE for elementary school children’s science learning.
