本文基于教学实践探讨了线上线下混合式教学模式的效果，提出了对策与建议. 实验数据显示采用混合式教学模式的班级成绩分布离散程度小、及格率高，其中重视课前预习的学生学习效果更佳. 研究表明，应在尊重不同学习风格的基础上采取多样化的教学策略; 作业的同质化现象制约了教学效果的提升，扎实构建“三全育人”体系是解决该困境的根本要素;混合式教学模式在大班教学中的深度应用有赖于教育信息化技术的进一步完善和教学考评方案的持续优化.

Based on the teaching practice，the effect of online- offline blending teaching

mode is discussed， and some countermeasures and suggestions are also put forward. The

statistical data show that the class in blending teaching mode has the characteristics of a low

dispersion degree of score distribution and a high pass rate. It also in- dicates that the students

who paid more attention to previewing would most likely gain a better learning effect. The

research shows that it is difficult to meet the needs of students in different levels in a

large class if only providing one set of online-video-resources. Therefore，diversified

teaching strategies based on respecting different learning styles should be formulated. The

consubstantial trend of course assignments restricted learning improving，and this phenomenon

required the solid construction of FWA Education，which is known as full - scale

education，whole- process education，all-around education. The deep application of online-offline

blending teaching mode for large- class depends on the modern educational technology

improvements，which could judge and feedback the subjective questions automatically. The evaluation

scheme of blending teaching mode should also be optimized in the view of the education

target of FWA Education.
