This study focuses on the design of performance task groups in primary school interdisciplinary theme – based learning. Interdisciplinary theme – based learning is carried out in accordance with the requirements of the compulsory education curriculum plan for the primary school stage. Its interdisciplinary and practical nature helps to cultivate students’ core competencies. The study constructs performance tasks based on the SOLO hierarchical analysis method, and establishes teaching objectives according to the curriculum standards. These objectives cover dimensions such as labor concepts, abilities, habit qualities, spirits, and interdisciplinary competencies. The study elaborates around “the design and production of LED products”, determines learning outcomes corresponding to different SOLO levels, and constructs task groups, including tasks such as team formation, research reports, plan design, sketch drawing, and material budget formulation. It also presents the direction for optimizing the task group, from building the team structure to making material budget decisions. The aim is to promote the development of students’ thinking in interdisciplinary teaching, achieve the coordination of knowledge, skills, and competencies, and contribute to the effective teaching of primary school interdisciplinary courses.
