数字化学习环境优势之一在于满足学习者个性化学习需求，实现个性化学习的基础是精准诊断学习者的相关特征属性，以此为依据提供适应性的支持反馈。文章基于前概念理论的认知诊断方法，利用二阶诊断方法和数理统计方法构建学习者前概念体系，来诊断学习者在学习具体学习内容时的认知状态。文章以初中物理“力与运动”主题为例，阐述基于前概念理论的学习者认知诊断方法与其应用过程，诊断方法作为智慧学习环境的一个诊断维度，能够提高学习环境对学习活动的支持效果，包括可视化呈现诊断学生的前概念状态；对错误概念进行归因分析，为适应性学习内容组织提供依据；预测学习者在未来学习过程中可能遇到的阻碍，为生成适应性学习路径提供依据。
【英文摘要】：
One of the advantages of digital learning environment is to meet the personalized learning needs of learners，and the basis of personalized learning is to accurately diagnose learners' relevant characteristics, so as to provide adaptive support feedback. Based on cognitive diagnostic method of preconception theory, using two-state diagnostic questionnaire and mathematical statistics method, this paper builds learners' preconception system to diagnose learners' cognitive status in learning specific content. This paper takes "Force and Motion" in physics of junior high school as an example, explains learners' cognitive diagnostic method and application process based on preconception theory. As a diagnostic dimension of smart learning environment, the diagnostic method can improve the support of learning environment on learning activities, including visual presentation of students' pre-conceptual state, attribution analysis of the wrong concept, provides evidence for content organization of adaptive learning, predicting learners' obstacles encountering in the future, providing evidence for generating adaptive learning path.
