数学学科公式多,运算复杂,容易使学生感到枯燥,因此,教师尤其要注意数学教学的趣味性。课堂教学中针对某些内容可联系生活、生产中的事例来启发学生思考,把课上得生动活泼些。例如,不等式组解的几种情况是教学中的一个难点,学生常常在解题时发生差错,我在教学中除了利用数据和数轴,注意数形结合以外,还结合生活实例向学生发问:假如一户人家养了几只小鸡和大鸡,现在要用木条钉鸡笼,使小鸡、大鸡都不能逃出来,木条之间的距离该怎样?若要在笼上开一个门,要求小鸡大鸡都能自由出入,问门该多大?
Mathematical disciplines and more formulas, computational complexity, easy to make students feel boring, therefore, teachers should pay particular attention to the fun of mathematics teaching. Classroom teaching for some content can be linked to life, production of examples to inspire students to think, the class lively and lively. For example, inequality group solution of several situations is a teaching difficulty, students often in the problem-solving error, I in addition to teaching in the use of data and the number of axes, note the combination of figures, but also with examples of life questions to students: If A family raised a few chickens and big chickens, now use a wooden nail cage, so that chickens, chickens can not escape, the distance between the wood how to? To open a door in the cage , Require chick chickens are free access, asking how much?
