There has been an increasing number of calls to apply new technologies to learning contexts for STEM education. However, limited studies have explored the role of technology in bridging teachers and children to create STEM knowledge collaboratively. Therefore, early childhood teachers encounter challenges integrating digital technologies to support children’s STEM learning. The challenges include developing effective and innovative scaffolding strategies to incorporate digital technology and visualize the processes of using technologies in children’s STEM knowledge building. This study reports on an in-depth exploratory case study from a kindergarten classroom in Hong Kong, exemplifying a new approach to integrating digital technologies within spatialized STEM learning. The case selected continuity learning episodes from a spatially directed STEM learning unit on making a safe traffic city. Under digital technology-integrated scaffolding, the teacher and children co-created a traffic symbolic system by designing symbols of landmarks, developing and applying spatial language, making maps and traffic games with rules. The thematic analysis was adopted to analyze the teachers’ STEM activity plans and reflective reports. The finding indicated that the process through which the teacher and children collaboratively created STEM knowledge via technology-integrated scaffolding involved recalling spontaneous understanding about everyday concepts, exploring ideas in authentic contexts, sorting and organizing their collected information, and identifying and correlating abstract concepts with corresponding everyday practices. The children required two levels of technology-integrated scaffolding strategies to engage in STEM knowledge collaborative creation: scaffolding for technology using and scaffolding through use of technology. Three novel roles of technology emerged that transform learning from knowledge delivery to collaborative creation in inquiries STEM tasks for young children

Coding is a crucial foundation for young children's cognitive development that enhances their logical and computational thinking skills for long-term learning. This study examines how young children in Hong Kong acquire coding skills through integrated STEM activities. In an innovative educational program enacted in a technology-rich 'Creative Lab' with augmented reality (AR), virtual reality (VR), and a 3D printer, the study focuses on three children aged 6–8. An explanatory case study approach was employed to collect data from classroom observations and teacher interviews. Observations targeted children's learning progress in coding activities, while the interview unpacked the applied teaching repository. The findings reveal that young children developed early coding skills using various technologies to create and apply symbols. Three strategies scaffold children’s skills enhancement stemmed from situated learning theory: 1) integrating learning content in an authentic context, 2) leveraging learners' intuitive knowledge through inquisitive practice, and 3) providing immersive learning resources. Copyright © 2025 Informa UK Limited, trading as Taylor & Francis Group.
