Preschool experience in 10 countries: Cognitive and language performance at age 7

The IEA Preprimary Project is a longitudinal, cross-national study of preprimary care and education designed to identify how process and structural characteristics of the settings children attended at age 4 are related to their age-7 cognitive and language performance. Investigators collaborated to develop common instruments to measure family background, teachers’ characteristics, setting structural characteristics, experiences of children in settings, and children's developmental status. Data from 10 countries are included in the analysis; in most countries, the sample of settings is representative of preprimary settings in that country. For the analysis, a 3-level hierarchical linear model was employed that allowed decomposition of variation of child outcomes into three parts—variation among children within settings, among settings within countries, and among countries. Four findings are consistent across all of the countries included. Age-7 language improves as teachers’ number of years of full-time schooling increases and the predominant type of activity teachers propose in settings is free choice rather than personal/social. Age-7 cognitive performance improves as children spend less time in whole group activities and the variety of equipment and materials available increases. There were also a number of findings that varied across countries depending on particular country characteristics. The findings support child-initiated activities and small group activities and are consistent with developmentally appropriate practices promoting active learning.
