我在教学《风》一课(人教版六年制九册6课)时,先让学生弄清什么是风。刮风是学生常见的一种自然现象,究竟风是什么、风又是怎样形成的,在他们的头脑里却并没有一个明晰的认识。让学生经历通过观察——提出问题——进行思考——获得认识,这些活动,意在诱导他们积极投入自行探索知识这一过程。教师引导学生观察课本插图,提问学生刮风时有什么现象?学生能根据平时刮风的经历,说刮风时树枝摇摆,地面的树叶会被风刮跑,人迎风走路会感到费力……这些现象都是认识风的本质的感性基础。 接着启发学生思考:你看到旗子在风中飘动,烟柱被风吹得倾斜、树叶被风刮跑,你也能感到风的吹拂和力量,可是你能看得见风吗?学生答不能看见。在我们周围,什么物体是看不见的?学生很容易想到是空气。
I am teaching the “Wind” lesson (PEP 6-year, 9-year, 6-lesson), let the students first understand what is the wind. Windy is a natural phenomenon common to students. It is not clear what the wind is and how the wind is formed in their minds. Getting students through observation - asking questions - thinking - getting acquainted with these activities is intended to motivate them to actively engage in the process of exploring knowledge themselves. Teachers guide students to observe the textbook illustrations, ask students what happens when the wind blow? Students can usually according to windy experience, said windy branches swinging, the leaves of the ground will be the wind ran away, people windward walk will feel hard ... ... these Phenomena are the emotional basis for understanding the nature of the wind. Then inspired students to think: you see the flag fluttering in the wind, the smoke column was tilted by the wind, the leaves were blowing wind, you can feel the wind blowing and strength, but can you see the wind? Students can not see . What objects are invisible around us? Students easily think of the air.
