新课程改革背景下,小学数学教学在许多方面发生了重大变化,解决问题教学便是其中之一。实验教材不再专门设置应用题教学单元,而代之以“解决问题”或“用数学”的称呼,并把它渗透在四个学习领域之中。以前,在旧版本的教材中,有的数学题目有固定的解题思路与公式,做题时,有的学生常常会根据一种题型的解题思路去联想,思考并解决另外的题型,还有一种学生是能看清题型,用此类题型特有的套路去列式解答,这类学生对题目不能很好地分析理解,只有盲目、
In the context of the new curriculum reform, the mathematics teaching in primary schools has undergone major changes in many aspects. Teaching of problem solving is one of them. The experimental textbook no longer specifically sets up the application-oriented teaching unit and instead calls it “problem solving” or “math” and infiltrates it into four areas of study. Previously, in the old version of the textbook, some math problems have fixed problem-solving ideas and formulas. When making a question, some students often think, solve and solve other problems according to a problem-solving idea , There is a student is able to see the problem type, with such questions unique routines to solve the problem, these students can not be a good analysis of the problem, only blind,
