An individualized homework precise pushing service system and method based on whole-lesson learning situation portrait

Abstract

This invention relates to the interdisciplinary field of computer application technology and educational informatization, and discloses a personalized homework precision push service system and method based on full-grade learning profiles. The system adopts a five-layer architecture (as shown in Figure 1): data acquisition layer, algorithm engine layer, application service layer, front-end interaction layer, and commercial operation layer. The algorithm engine layer includes a five-level tag-based graded question bank module, a dynamic learning profile module, a grade-level push algorithm module, and a closed-loop optimization module. The dynamic learning profile module configures weight coefficients α, β, and γ for four levels: lower elementary, upper elementary, junior high, and senior high school, respectively. The mastery of each knowledge point is calculated using the formula: total profile score = α × academic score + β × classroom score + γ × behavior score, and updated incrementally weekly. The grade-level push algorithm module automatically filters out knowledge points with a mastery ≥ 0.85 based on grade-level differentiated allocation rules and generates customized homework packages. The closed-loop optimization module iteratively optimizes the learning profile based on incorrect question data. The commercial operation layer uses RBAC permission control to divide the system into a free basic version and a paid value-added version, achieving functional and data isolation. This invention solves the combined challenges of unified adaptation across all educational stages, multi-dimensional dynamic profiling, differentiated push notifications for different educational stages, data closed-loop self-optimization, and commercially sustainable operation, significantly improving the accuracy of student profiling and homework efficiency, while reducing the burden of grading for teachers.
