将活动内容渗透到教学过程中1.随堂演示。讲授“大洲和大洋”时,为了让学生充分感知世界上海陆分布的不均、海洋分布面积所占比例远远大于陆地这一事实,首先让学生课前先准备好一个小地球仪,并先进行课前预习,课堂上,可让学生旋转立体地球仪,在旋转过程中,学生闭上眼睛,然后用右手触摸地球仪,活动完毕最后让学生观察右手拇指所在位置是海洋多还是陆地多,并统计全班同学中,右手拇指所触摸到海洋及陆地的人数。活动的结果使学生对海陆的分布有了初步的认识,当然这一做法并不具有科学性,但却极大地调动了学生的学习热情,增加了课堂教学的直 To infiltrate the activity into the teaching process. When teaching “Continents and the oceans,” in order to make students fully aware of the uneven distribution of land and sea in the world, the proportion of the marine distribution area is far greater than that of land. First, students should prepare a small globe before class, Before class, class, students can rotate the three-dimensional globe, in the process of rotation, the students close their eyes, and then touch the globe with his right hand, activity is completed Finally let the students observe the right thumb where the location is more or less ocean and land statistics Classmates, the number of people touched by the right hand thumb to the ocean and land. The result of the activity has given students a preliminary understanding of the distribution of land and sea. Of course, this approach is not scientific, but it has greatly aroused the students’ enthusiasm for learning and increased the importance of classroom teaching
