在移动互联网时代背景下，线上线下混合式教学成为各高校大力推广的新型信息化教学模式。为了探索线上线下混合式教学在高校中的应用效果，以促进学生专业知识水平的有效提升，选取东南大学土木工程学院工程管理专业参与工程经济学A课程学习的本科生为研究对象，以MOOC线上教学平台为数据来源，选用SPSS24.0统计分析软件，从观看视频个数、观看视频时长、出勤次数、课堂练习正确率四个指标进行本科生线上及线下学习情况分析，最后从线上成绩、课后作业成绩两个方面进行期末考试成绩的相关性分析。结果表明，线上成绩及课后作业成绩与期末成绩存在显著正向相关，线上线下混合式教学有利于培养学习者自主学习、探究实践的科学素养，进而提高学习效果。

n the mobile Internet era, online and offline mixed teaching mode has become a new information-based teaching mode vigorously promoted by universities. With the purpose of exploring the application effect of online and offline mixed teaching mode in university and thus effectively improving students’ professional knowledge level, taking undergraduate students who major in the course of engineering economics A of Civil Engineering College of Southeast University as the research object. It takes MOOC online teaching platform as the data source, uses SPSS24.0 software for statistical analysis, and analyzes the online and offline learning situation of undergraduate students from four indicators: the number and duration of video viewing, attendance and the accuracy rate of classroom practice. Finally, the final examination results are analyzed from two aspects of online performance and after-class homework performance. The results show that there is a significant positive correlation between online scores, after-class homework scores and final examination scores. Online and offline mixed teaching mode is beneficial to develop learners’ scientific literacy of autonomous learning and inquiry practice, which can improve learning effect.
