目的 为改善学生用户对在线学习平台的体验满意度，使设计师精准把握设计重点与优先级，以有效提升平台用户体验、促进平台的可持续发展。方法 在APEC用户体验模型的基础上引入结构方程，提出一种在线学习平台用户体验设计框架。通过理论模型结合深度访谈，提取影响在线学习体验的设计要素，并通过问卷分析建立在线学习平台用户体验满意度的结构方程模型，计算各设计要素影响权重，得出设计优先级与设计策略。结论 构建了基于APEC模型与结构方程模型的用户体验设计框架，并将其应用于大学生在线学习平台设计中，提升平台的用户体验水平，为相关用户体验设计研究提供一定理论参考。

The work aims to enhance the satisfaction of students with the e-learning platform experience and make designers accurately focus and prioritise their designs to improve the user experience and promote the sustainable development of the platform. A structural equation was introduced based on the APEC user experience model and then a user experience design framework for e-learning products was proposed. Firstly, by combing the theoretical model with interviews, the design factors influencing the e-learning experience were extracted. Secondly, a structural equation model of e-learning platform user experience was built through questionnaire. Then, the influence weight of each design factor was calculated to derive design priorities and design strategies. The user experience design framework based on the APEC model and the structural equation model is constructed and then applied to the experience design of e-learning platform for university students, which improves the user experience level of the e-learning platform and offers reference for relevant experience design research.
