Relationship Between Numeracy and Vocabulary Skills in Indonesian Preschool Children and the Impacts of Learning Environments

Although many studies on early childhood have been conducted, there is still a need for further research on numeracy and vocabulary skills, particularly in Indonesia. This research aims to confirm the correlation between numeracy and vocabulary skills in preschool children and to disentangle the effects of environmental factors on both numeracy and vocabulary skills. This research was conducted at Early Childhood Education and Care (ECEC) in the Jatinangor district and followed the principle of simple random sampling. Children were given numeracy and vocabulary tests, parents were asked to fill out a questionnaire about sociodemographic aspects and the learning environment in their homes, and teachers were asked to fill out a questionnaire about preschool activities concerning numeracy and vocabulary. Data were analyzed using a structural equation model with numeracy and vocabulary as outcome variables. Covariates such as age, gender and social status were also included in the model. The results of this study show that numeracy is closely linked to vocabulary skills and that only a specific preschool activity can explain the variance of numeracy. On the other hand, both home numeracy activities and a specific preschool literacy activity are significant predictors of vocabulary skills.
