The purpose of this study was to examine the effects of young children’s stay
hours on kindergartens or child care centers on their language, cognition, and
social development with teacher-child interactions as a mediator. For this
purpose, the data from the 2013 Panel Study on Korean Children were analyzed
using the GLM and pattern analysis. The results of the GLM analysis were as
follows. First, the main effects of the stay hours on child development were
statistically significant Second, the main effects of the level of teacher-child
interaction were also statistically significant on the results of child development.
Third, the moderating effect of teacher-child interaction level between the stay
hours and child development were also significant. The results showed that
young children’s stay hours effected their language, cognitive, and social
development and teacher-child interactions mediated these effects.
