新课程理念认为:学生的知识不是单纯由教师传授得到,而是学生在一定的情境中在教师的引导下自主建构的。离开情境,学生的自主建构则成为无根之木,无源之水。根据教学目标和教学内容精心创设数学教学情境,可以点燃学生的学习热情,引领学生发现问题、探究问题、解决问题,促进学生在数学学习中主动建构自己的数学知识。但是在我们的数学课堂中一些看似热闹非凡,实
The concept of the new curriculum that: students' knowledge is not simply taught by teachers, but students in a certain situation under the guidance of the teachers to build their own. Leave the situation, the student's self-construction has become a rootless, passive water. According to teaching objectives and teaching content to create a mathematical teaching situation carefully, you can ignite the enthusiasm for learning students, leading students to discover problems, explore problems, solve problems and promote students in mathematics to actively construct their own mathematical knowledge. But in our math class some seemingly bustling, real
