本案例教学内容是苏教版数学四上的“找规律”。在本课中,笔者力图打造“自主+合作”的生本数学课堂,着力培养学生的探究意识,提升学习能力。一、联系生活,激趣导入多媒体课件出示三种男女生列队方式。(图片中为本班学生。①排成一行,男女生间隔,两端同为女生;②排成一行,男女生间隔,两端分别为男、女生;③排成圆形)让学生发现男女生排列的共同特点。(选择学生自己的照片创设情境,既激发学生的兴趣,也让学生理解间隔排列的概念,并初步体会间隔排列的特点
The teaching contents of this case are the “rules of finding” in the fourth edition of the Sujiao edition. In this lesson, the author seeks to create a math class of “Autonomous + Cooperative” students to cultivate students’ awareness of inquiry and enhance their learning abilities. First, contact life, interest in introducing multimedia courseware to produce three kinds of boys and girls lined up. (The picture for the class students.) ① lined up, boys and girls interval, both ends of the same girls; ② lined up, boys and girls interval, both ends were male and female; ③ arranged in a circle) for students to find men and women Common features of students. (Choose students to create their own photos of the situation, not only stimulate student interest, but also allow students to understand the concept of spaced arrangement, and initially realized the characteristics of the arrangement of intervals
