十多年来,笔者一直都担任普通班的数学教学,最深的体会是“要想学生真懂会用,还是要靠他们独立思考、自主探究弄懂才行”。由于普通班学生学习能力比较低,要想提高课堂效率,最重要的是调动学生参与课堂的积极性。如果课堂上没有调动起学生的积极性,那么一定是效率低下,必定出现“讲了n遍仍不会”“听懂了却不会用”等无奈现象。建构主义学习理论认为,知识不是通过教师传授获得的,是学习者在一定的情景下,借助于其他人(包括教师和学习伙伴)的帮助,利用必要的学习资源,通过意义建构的方式获得的。这说明真要掌握知识,需要学生积极参与课堂教学。
For more than a decade, I have been teaching mathematics in ordinary classes. The deepest experience is that “if students really understand how to use them, they must rely on their independent thinking and make their own exploration and understanding.” Due to the low learning ability of ordinary students, in order to improve classroom efficiency, the most important thing is to mobilize the enthusiasm of students in the classroom. If the classroom did not mobilize the enthusiasm of the students, then it must be inefficient, there must be “Speak n times will not ” “Understand but will not use ” and other helpless phenomena. Constructivism theory of learning that knowledge is not taught through the teacher to obtain, is the learner under certain circumstances, with the help of other people (including teachers and learning partners), the use of the necessary learning resources, through the construction of meaning obtained . This shows that really want to grasp the knowledge, students need to actively participate in classroom teaching.
