The document discusses the rationale for curriculum reforms in Indonesia from the School-Based Curriculum (SBC) to the 2013 Curriculum (K-13). Key reasons for change included that the SBC did not adequately address character education, active learning methods, balancing soft and hard skills, and entrepreneurship. The K-13 aims to develop students' characters and relevant skills based on their interests through a thematic approach. It emphasizes competency-based learning and assessment of students' attitudes, skills, and knowledge using four core competencies. The K-13 also implements a scientific learning approach and integrated thematic materials to prepare students for a changing world.
