The aim of this study is to determine the status of preschool teachers toward applying digital technology (DT) in early childhood education (ECE) and the barriers they face. A quantitative online survey was conducted with 823 full-time preschool teachers in Vietnam's Central and Central Highlands. Results showed that teachers just often use smart TV and laptop computers among technical devices. Technical tools were mainly used to gather information and documents for lesson planning, compose lesson plans, communicate with parents, and present information to children. In addition, preschool educators faced many barriers in applying DT into their classrooms, such as lack of technology devices, lack of technical support or assistance, and lack of technical skills. The results also showed the differences between urban, rural, and mountainous areas in many aspects. The findings of this study may provide reliable information for educational management agencies and preschool teacher training institutions in making and implementing policies related to the application of DT in ECE and fostering technology application capacity for preschool teachers. Some suggestions for enhancing technology use in early childhood classrooms are proposed.
