Abstract: The "Double Reduction" policy is to put forward higher requirements for the construction of the homework system, rather than negating its value entirely. Establishing a high-quality assignment system holds significant importance for promoting students' holistic development. Currently, various challenges persist in this construction process: At the cognitive level, the dominance of exam-oriented and standardized approaches leads to the exclusion of imagination from the assignment system.At the behavioral level, practices involving disciplining and alienation result in the marginalization of ethics within the system's construction. At the affective level, abstraction and limitations cause the absence of aesthetic considerations in the assignment system's design. Imagination stimulation, ethical awakening and aesthetic experience emerge as the three value pursuits of high quality assignmen system construction under the background of the "Double Reduction" framework.. Therefore, the construction of high quality operation system needs to be promoted from three main areas: 1) igniting imaginative vitality within assignments, 2) enhancing ethical care embedded in assignments, and 3) uncovering the intrinsic aesthetic dimensions of assignments.
