  • 摘要: 在教育评价改革深入推进的背景下,如何借助人工智能(AI)实现在线学习过程的智能识别与精准反馈,成为推动教学质量提升的关键命题。为此,该文设计了一种融合学习行为轨迹与学习结果数据的智能评价模型,用以支持学生学习状态的识别与分层诊断。模型以动态时间规整(DTW)算法为核心,用于度量学习行为的时序相似性,结合K-Means与K-Medoids聚类结果实现双向融合建模。基于595名大学生的在线学习平台日志与成绩数据,构建学习过程与结果双维度评价体系,识别出5类典型学习者画像,并基于滞后序列分析挖掘其代表性行为路径。研究发现,学习过程深度与学习结果层次呈显著正相关关系,模型具有较强的识别能力与诊断功能,可为个性化教学干预与分层指导提供支持。研究不仅验证了人工智能方法在过程性评价中的应用价值,也为教育强国背景下的教学质量提升与评价体系创新提供了理论和方法支撑。

     

    Abstract: In the context of deepening educational evaluation reform, how to leverage artificial intelligence to intelligently identify and provide precise feedback on online learning processes has become a key issue in enhancing teaching quality. To address this, this study proposes an intelligent evaluation model that integrates learning behavior trajectories and learning outcomes data, to support the identification and stratified diagnosis of students' learning states. The model, based on the Dynamic Time Warping(DTW) measures the temporal similarity of learning behaviors, and bidirectional fusion modeling is achieved by combining K-Means and K-Medoids clustering. It utilizes learning logs and academic performance data from 595 college students to construct a dual-dimensional evaluation framework covering both learning processes and outcomes. The analysis identifies five typical learner profiles and identifies representative behavioral paths through lag sequence analysis. Results reveal a significant positive correlation between the depth of the learning process and the level of learning outcomes. The model demonstrates strong recognition and diagnostic capabilities, which can support personalized teaching interventions and stratified guidance. This study not only validates the application value of artificial intelligence methods in process assessment but also provides theoretical and methodological support for enhancing teaching quality and innovating evaluation systems under the context of building China into a leading country in education.
