Augmented reality (AR) technology is increasingly utilized in cognitive development and education of preschoolers. The Augmented Reality Integrated STEM Preschooler (ARISP) module combines AR technology with STEM (Science, Technology, Engineering, and Mathematics) in teaching and learning activity. This study aims to assess the impacts of the ARISP module for teaching and learning activity on children from preschool teachers' perspectives. The research methodology includes semi-structured interviews with preschool teachers and observation implementing the ARISP module for teaching and learning activity. The study examines children's interaction with AR technology, their response to the immersive learning environment, and the development of skills crucial for digital literacy. Findings indicate that the ARISP module significantly increases children's engagement and motivation in learning activities. The interactive nature of AR technology fosters a deeper understanding of STEM concepts and enhances problem-solving skills. The ARISP module demonstrates substantial promise in enriching early childhood education by integrating cutting-edge technology with traditional learning approaches.
