Preschool a booster for East Asia, Pacific children, Hong Kong researchers find

Young children in East Asia and the Pacific who attend preschool show better cognitive, language and socio-emotional development than those who don’t, according to a new study by The Education University of Hong Kong, published in Early Childhood Research Quarterly.


The study’s findings highlight the importance of making early childhood education more accessible in the region, lead author Dr Jin Sun said. 


Dr Sun, who worked with The University of Hong Kong, Stanford University School of Medicine in the US, and Telethon Kids Institute in Australia to reach the findings, analysed data from 4,712 ethnic majority three-to-five-year-olds in Cambodia, China, Mongolia and Vanuatu. 


The researchers examined the effects of participation, intensity (hours per week), duration (months attended), and total dosage (total hours attended) of early childhood education on children’s cognitive, language and socio-emotional development. 


Cognitive development was measured by a child’s ability to count, add and subtract, know shapes, and in terms of their short-term memory and behavioural inhibition. Language was measured by children’s abilities to express themselves, write and draw. Socio-emotional development was measured according to a child’s social comprehension, etiquette and ability to recognise emotions.


The researchers found that participation in early childhood education, such as kindergarten, pre-primary classes or community preschool, was positively associated with all three types of childhood development. 


Attending early childhood education for longer hours per week was associated with higher scores in all developmental domains in children in Mongolia; higher language scores in Cambodia; and lower socio-emotional scores in Cambodia and China. A higher total dosage of early education was associated with better cognitive and socio-emotional scores in China and better language scores in Mongolia.


“Our results indicate that early childhood education is beneficial for children’s early development, but many children in the region are unable to reap these rewards due to barriers to access,” Dr Sun said, calling for more efforts by policymakers in the region to ensure that all children have access to a quality early education.


While similar studies of this nature have been conducted, they have typically been run in high-income countries, where only 18 per cent of children are born. As such, the researchers wanted to develop a better understanding of the impacts of early childhood education in East Asia and the Pacific. 


According to UNESCO figures, only two-thirds of children received pre-primary education in the region in 2012.


As a result of the findings, which may be accessed here, the scientists recommend that further studies be conducted to assess the content and quality of early childhood education in the region.
