前段时间拜读了某期刊中两篇关于“体积与容积”的教学设计的文章。其中有两个概念引发了我的思考,苦思冥想后,觉得还是有必要把我的想法写出来与同行们交流、探讨,希望同行不吝赐教。思考一:同一个物体的体积大于容积。这是在《让学生深透理解数学概念》一文中关于“体积与容积”的教学建议提到的。文中还利用电饭煲对体积与容积的概念进行了解读:利用课件将电饭煲的厚度逐渐变小,在每一次变化后,引导学生观察比较,发现电饭煲的容积与体积更接近了一些,差距
Some time ago read a magazine about two “volume and volume” of teaching design articles. Two of these concepts triggered my thinking. After thinking hard and meditating, I felt it was necessary to write down my ideas and exchange ideas with my colleagues to explore and hope that my colleagues would give me advice. Thinking one: the same object is larger than the volume of volume. This is mentioned in the teaching recommendations on “Volume and Volume” in “Making Students Understand Mathematical Concepts.” The paper also uses the electric cooker on the concept of volume and volume are interpreted: the use of courseware will gradually reduce the thickness of the rice cooker, after each change, to guide students to observe and compare, found that the volume and volume of rice cookers closer to some, the gap
