问题引领的高职“化学基础”线上线下混合教学模式探讨——以“化学反应速率和化学平衡”为例

Discussion on the Problem-oriented Online and Offline Mixed Teaching Mode of“Chemical Foundation”in Higher Vocational Colleges——“Chemical Reaction Rate and Chemical Equilibrium”

以“化学反应速率和化学平衡”为教学案例:课前,线上教学实现对知识的初步认知与传递;课中,线下教学,实现知识的理解、运用与深入认知;课后,线上教学,重在知识的迁移,实现更高级的认知目标。结果表明,学生与教师互动增强,问题交流讨论度与解决的能力得到提高;自主学习能力、知识的掌握与应用能力得到提升,学生成绩也提高。

Chemical reaction rate and chemical balance was used to be a teaching case.The purpose of online teaching before class was the preliminary cognition and transmission of knowledge.The off-line teaching in-class was operated to realize the understanding,application and in-depth cognition of knowledge.The online teaching after class focused on the transfer of knowledge and the realization of higher cognitive goals.The results of the teaching showed that the interaction between students and teachers,the degree of problem exchange and discussion and the ability to solve problems were improved.The ability of autonomous learning,mastery and application of knowledge,and the students'performance were also raised.
