Background: The implementation of the Merdeka Curriculum requires teachers to apply differentiated learning supported by flexible and engaging digital teaching materials. However, teachers at Sekolah Indonesia Kota Kinabalu (SIKK) face limitations in developing effective microlearning-based materials that accommodate diverse student learning needs.Aims: This community service program aims to improve teachers’ competence in developing microlearning-based teaching materials to support differentiated learning at Sekolah Indonesia Kinabalu.Methods: The program employed Focus Group Discussion (FGD) and mentoring methods involving 30 teachers from SIKK and Community Learning Centers (CLC) in Sabah and Sarawak. The activities included needs identification, training design, hands-on workshops, development of digital microlearning materials, and product evaluation.Results: The results show a significant improvement in teachers’ understanding and skills in designing microlearning-based teaching materials. Teachers successfully produced various digital learning products such as interactive videos, infographics, presentations, and gamified content. Program evaluation indicated high participant satisfaction in terms of training materials, facilitation, and relevance to instructional needs.Conclusion: The FGD and mentoring-based community service program effectively enhanced teachers’ competencies in developing microlearning to support differentiated learning. This program contributes to strengthening the implementation of the Merdeka Curriculum and can be adopted more broadly to improve learning quality in Indonesian schools, particularly those located abroad.
