教师在教学中要遵循学生的认知规律,将知识性、应用性、趣味性和谐地结合起来,充分调动学生的学习积极性,从小就培养和提高学生的数学应用能力。一、挖掘教学知识点,展示数学的趣味性和奇异美在教学中要紧扣教材,多设计或引用与教学内容有关的新颖有趣而富有思考的问题,使课堂教学生动、活泼、富有吸引力。如在讲授圆的有关性质前,提出问题:车轮为什么是圆的?电脑分别模拟安装有三角形轮子、正方形轮子、椭圆形轮子和圆形轮子的汽车行驶的状态,并分别配各种颠簸沉重的声音及轻快的声音。
Teachers in teaching to follow the cognitive rules of students, knowledge, applicability, interest and harmonious combination of fully mobilize the enthusiasm of students learning from an early age to develop and improve students’ ability to math application. First, to tap teaching points of knowledge to show the interest of mathematics and singular beauty in teaching should be closely linked to teaching materials, design or cite more interesting and thought-provoking questions related to teaching content so that classroom teaching is lively, lively and attractive . For example, before asking about the nature of the circle, the question was asked: Why is the wheel round? The computer simulates the states of the vehicles fitted with triangular, square, oval, and round wheels, respectively, with various types of heavy, bumpy Sound and light sound.
