High-quality teacher-child interactions benefit children’s learning and developmental trajectories. However, professional development (PD) opportunities for early childhood teachers on how to interact with children are typically insufficient. To enhance teacher-child interactional quality in Hong Kong kindergartens, we designed an online PD entitled Chat with Children, composed of 10 units of learning resources and activities. The objective of this study was to explore how this online PD influenced teachers’ beliefs and intentions regarding teacher-child interaction. Participants were 217 in-service Hong Kong kindergarten teachers. Pre-post evaluation was conducted to examine teachers’ beliefs and intentions in the dimensions of Organization of the Teaching Experience, Group Sensitivity, Encouragement of Communication, and Behavioral Support. After taking the course, teachers had stronger beliefs and intentions to organize interactive activities, address children’s needs with sensitivity, and engage children in communications. Furthermore, teachers believed that they should give children more freedom to settle conflicts, rather directing their misbehaviours immediately. This study provides evidence on the potential of online PD to enhance teachers’ beliefs and intentions regarding how to engage children. Implications, limitations, and future research are discussed.

Despite the rise of online professional development (PD) for early childhood educators, few studies have examined their perceptions of the usefulness of learning resources. We developed an online PD centered on teacher-child interactions, based on the critical features of high-quality PD. The PD was composed of 10 units with a variety of learning resources, including video lectures, research notes, testimonials, classroom videos, quizzes, reflection activities, and sharing activities. We examined teachers’ perceptions of the usefulness of such learning resources and explored potential differences based on key demographic variables. Participants were 137 in-service Hong Kong kindergarten teachers. Evaluation surveys and semi-structured interviews were utilized after course completion. Classroom videos, which provided real-life examples, were perceived as most useful resource to improve teaching practices. Participants also considered video lectures, research notes, and testimonials as extremely useful resources, and reflection activities and sharing activities as useful resources. Quizzes emerged as the least useful resource, especially when these involved fact-based questions. Teachers’ perceptions were not influenced by their demographic backgrounds. We conclude that teachers place a higher emphasis on online PD resources that offer practical examples compared to those focus on theoretical knowledge and self-reflection. The current study filled an important gap in the early childhood teacher education literature, specifically in the area of online PD, offering theoretical, practical, and policy-related insights. Copyright © 2025 Author(s).
