This study aims to explore the use of Technological Pedagogical Content Knowledge (TPACK) in integrative thematic learning in primary schools. The research method used is qualitative with a case study approach. The research location is at SD Negeri Beraja Asri grade 6. The research data was collected through classroom observation, interviews, and document analysis. Data analysis is carried out using data reduction, data display, and data verification techniques. The results showed that the use of TPACK in integrative thematic learning in elementary schools had a positive impact. In the aspect of technological knowledge, teachers successfully integrate information and communication technology (ICT) in the planning and implementation of learning. They use a variety of ICT tools and applications that match the learning content and effective teaching strategies. In addition, teachers are also able to utilize pedagogical knowledge and content effectively to facilitate interesting and meaningful thematic learning for students. However, the study also revealed some of the challenges faced by teachers in implementing TPACK. Some of the challenges include limited access to ICT tools and resources, lack of adequate training for TPACK competency development, and obstacles in integrating TPACK into existing primary school curricula. The results of this study provide a better understanding of the use of TPACK in integrative thematic learning in primary schools. The findings of this study can form the basis for the development of training programs and educational policies that support the integration of TPACK in teaching practices in primary schools.
