课改实施了十多年,我们的数学课堂归根结底就是让学生能够获得适应未来社会生活和进一步发展必需的重要数学知识以及基本的数学思维方法和必要的应用技能,这是我们在新课程改革进程中达成的共识。我们不再把目光放在学生学会了什么,而是放在学生怎样学,在学习活动中了解、掌握了哪些数学思想方法。数学思想有许多,记得著名数学家华罗庚先生曾经说过:“数缺形时少直观,形少数时难入微。”也就是在实际数学教学中有数就有形、有形就有数,这就是数形结合思想,利用数形 After more than a decade of curriculum reform, our math class is ultimately to enable students to acquire important mathematical knowledge necessary for future social life and further development, as well as basic mathematical thinking methods and necessary application skills. This is our progress in the new curriculum reform In the consensus reached. We no longer focus on what our students have learned, but on what students learn and what mathematical thinking they have learned in their learning activities. There are many mathematical ideas, I remember the famous mathematician Mr. Hua Luogeng once said: “When the lack of shape less intuitive, shaped when the minority is difficult. ” That is, in the actual mathematics teaching, there are a number of visible and tangible, this is the number of Shape combination of ideas, the use of digital form
