In order to solve the problems of inefficient allocation of teaching resources and inaccurate recommendation of learning paths in higher education, this paper proposes a smart education optimization model (SEOM) by combining the improved random forest algorithm (RFA) based on adaptive enhancement mechanism and the Graph Neural Network (GNN) algorithm. The public data and information such as the national higher education intelligent education platform are collected, and SEOM is trained and verified. The results show that SEOM has high accuracy and generalization ability in three different teaching scenes: online mixed teaching, personalized teaching and project-based teaching. The Root Mean Square Error (RMSE) value in cross-validation is between 0.2 and 0.5, and the Mean Absolute Error (MAE) value is between 0.1 and 0.5. SEOM shows strong stability when dealing with multidimensional educational resources and complex teaching modes. The accuracy rate remains at 85-97%, indicating its reliability in personalized learning path recommendation. Further analysis shows that the chi-square freedom ratio is between 1.0 and 2.5, the fitting index and the adjusted fitting index are both above 0.85, and the comparative fitting index is close to 0.95, which shows that SEOM has high accuracy and rationality in capturing the dependence of knowledge points in different teaching modes. The Root Mean Square Residual (RMR) and Root Mean Square Error of Approximation (RMSEA) are both below 0.05, which indicates that SEOM has small residual and strong scene adaptability. In addition, in the abnormal network environment, the resource allocation efficiency of SEOM is above 60%, and the Shapley value is between 0.1 and 0.4, which shows that SEOM can adapt to the change of network environment and the resource allocation effect is still obvious. Generally speaking, SEOM can optimize the allocation of educational resources and recommend learning paths in a complex environment, and effectively improve the intelligence and efficiency of teaching decision-making, especially for university administrators and educational technology developers.
为了解决高等教育中教学资源分配效率低下和学习路径推荐不准确的问题,本文结合基于自适应增强机制的改进随机森林算法(RFA)和图神经网络(GNN)算法,提出了一种智能教育优化模型(SEOM)。收集了国家高等教育智能教育平台等公共数据和信息,并对SEOM进行了训练和验证。结果表明,SEOM在在线混合教学、个性化教学和项目式教学这三种不同教学场景中具有较高的准确性和泛化能力。交叉验证中的均方根误差(RMSE)值在0.2至0.5之间,平均绝对误差(MAE)值在0.1至0.5之间。SEOM在处理多维教育资源和复杂教学模式时表现出很强的稳定性。准确率保持在85-97%,表明其在个性化学习路径推荐方面的可靠性。进一步分析表明,卡方自由度比在1.0至2.5之间,拟合指数和调整拟合指数均高于0.85,比较拟合指数接近0.95,这表明SEOM在捕捉不同教学模式下知识点的依赖性方面具有较高的准确性和合理性。均方根残差(RMR)和近似均方根误差(RMSEA)均低于0.05,这表明SEOM残差小且场景适应性强。此外,在异常网络环境下,SEOM的资源分配效率高于60%,夏普值在0.1至0.4之间,这表明SEOM能够适应网络环境的变化,资源分配效果仍然明显。总体而言,SEOM能够在复杂环境中优化教育资源分配并推荐学习路径,有效提高教学决策的智能化和效率,尤其适用于高校管理人员和教育技术开发者。
