在平时教学中教师都会发现,通过一定的训练和指导,学生对与例题相近的、常见问题解题技能会明显提高,但只要题目稍加变化,学生就会变得不会思考,只能机械照搬或一筹莫展。是什么封闭了学生的思维空间?又该怎样打开这个空间,发展学生的数学思维呢?应该把学生思维的发展作为数学教学的核心,培养学生思维的灵活性和创造性,才能使学生经历真正意义上的数学学习。
In normal teaching, teachers will find that through a certain amount of training and guidance, the students’ skills of solving common problems and problems that are similar to the examples will be obviously improved. However, as long as the topics are slightly changed, the students will become less able to think and only the machinery Copy or do nothing. What closed the student’s thinking space? And how to open this space, the development of students ’mathematical thinking? The development of student thinking should be the core of mathematics teaching, cultivating students’ flexibility and creativity in thinking, in order to enable students to experience the true meaning On the maths learning.
