The application, advantages and disadvantages of learning management systems (LMS) and social networking systems in Chinese EFL courses, represented by Superstar--Xuexitong and WeChat, are introduced. The study aims to explore the relationship between the two educational technology tools and three dimensions of student engagement. Using an adopted and revised questionnaire from previous researches, the study measures the extent of impact of the specified educational technology tools on student engagement with the help of SPSS. Through the independent sample T tests, analysis of variance, correlation and regression, the study found that emotional engagement has the strongest positive effect on educational technology engagement. In addition, analysis of the four principal factors indicates that using LMS could engage students more than adopting social networking systems.
