新课标明确指出:要重点加强学生问题解决能力的培养,教会学生从数学角度出发,及时发现问题,并利用自身已掌握的基础知识和实践经验,形成解决问题的方法,最终促进各种数学问题的解决。小学数学问题是运用已有的数学概念、理论或方法,经过积极探索、思考才能解决的问题。而这样的问题应满足三个特性:(1)接受性,指学生能够接受这个问题,还可表现出兴趣;(2)障碍性,即学生当时很难看出问题的解法、程序和和
The new curriculum clearly pointed out: we should focus on strengthening the cultivation of students’ problem-solving skills, teach students from the mathematical point of view, identify problems in a timely manner, and use their own basic knowledge and practical experience to form a solution to the problem, and ultimately promote a variety of mathematics Problem solving. Primary school mathematics problem is the use of existing mathematical concepts, theories or methods, through active exploration, thinking can solve the problem. And such problems should meet three characteristics: (1) acceptance, that students can accept this problem, but also show interest; (2) impediment, that students were difficult to see the solution, procedures and
