本节课的设计以学生为中心,课前采用“翻转课堂”让学生自主复习。课中采用“先学后教,当堂训练”的教学模式进行教学,并通过“问题导学”激发学生对知识的复习欲望,调动了学生的积极性。本课时的复习安排突出复习的重点,做到有的放矢。 The design of this lesson is student-centered. Before class, use “Flip Classroom” to allow students to review independently. In the class, the teaching mode of “learning first, training after class” was adopted to teach, and students ’enthusiasm was mobilized by stimulating students’ desire to review knowledge through “problem-based learning”. The reviewing arrangements for this lesson highlight the focus of review, so that it is targeted.
