摘要
以往在线学习成绩检测系统,仅能给出得分情况,测评效果差。设计智慧学习视角下在线学习成绩智能测试系统,由初级资源层、中级平台层、高级应用层构成,通过学习科目、电子图书、在线测试、自我信息四大功能模块实现在线学习成绩的智能处理分析。采用基于IRT的知识水平诊断方法测试用户知识水平,通过MCMC方法推算考核参数,实现在线学习成绩的准确测试。实验结果表明,系统能够对用户的六级词汇水平进行精确测试,用户满意度和性能高。
The past online learning performance test system can only present scores,and has poor test and evaluation results. Therefore,an online learning performance intelligent test system from intelligent learning perspective is designed. The system is composed of the primary resource layer,intermediate platform layer,and advanced application layer. The intelligent processing and analysis of online learning performance are realized by means of four functional modules of learning subjects,electronic books,online test,and self information. The IRT-based knowledge level diagnosis method is used to test users ′ knowledge level,and the MCMC method is used to calculate assessment parameters,so as to realize accurate test of online learning performance. The experimental results show that the system can accurately test users ′ vocabulary level of CET6,and has high user satisfaction and performance.
