基于微课的翻转课堂在高中生物教学中的应用研究——以“基因指导蛋白质的合成”为例

Research on the Application of Flipped Classroom based on Micro Lesson in Senior High School Biology Teaching——Taking the“gene directed protein synthesis”as an example

从传统生物课堂教学弊端入手,分析基于微课的翻转课堂在生物教学中的优势,以"基因指导蛋白质的合成"为例进行教学分析,围绕"遗传信息的传递"设计了翻转课堂的三个环节,并进行实践。结果表明,基于微视频和任务单的课前学习增强了学生学习的自主性和积极性;课中教师有针对性讲授和指导达到了知识内化的效果,课后混合式教学评价显示基于微课的翻转课堂有益于学生综合能力的培养。

The article begins with the disadvantages advantages of flipped classroom based on micro lecture in of traditional biology classroom teaching, and analyzes the biology teaching. We set ＂gene directed protein synthesis＂ as an example for teaching analysis, and design three links of flipped classroom around ＂genetic information transduetion＂. The results showthat pie-class learning based on micro video and task lists can enhance students＇ autonomy and enthusiasm in study. Teacher＇s targeted lecture and guidance in class can achieve internalization of knowledge. The hybrid teaching evaluation after class shows that flipped classroom based on micro lecture can enhance students＇ comprehensive ability.
