摘要:数学教学的重要环节是解题训练。一方面数学解题教学可以帮助学生理解概念、巩固法则以及运用数学知识;另一方面,在解题活动过程中,学生可以通过观察、比较、分析、顿悟、联想、尝试错误等思维活动,不断提高数学思维的能力。在数学问题解决的过程中,一题多解是普遍存在的思维活动,这不仅能激励学生的学习兴趣,调整学习的积极参与性,而且有利于培养学生独到的数学能力。一题多解还可以增强数学题的使用价值,也可以帮助学生提高解决问题的能力,促进解决问题的思路,还可以开阔他们的思维,培养解决问题的灵活性,增加他们的知识和智慧,以及提高知识之间的联系和运用。教师培养学生一题多解能够提高思维灵活性,促进智慧,还能影响学生解决其它学科问题的方法,灵活的掌握知识间的联系,从而培养他们的创造性。

Abstract:solving training is an important part of Mathematics teaching.On the one hand,Mathematics problem-solving teaching help the students to understand the concept, consolidating the rule, the application of mathematical knowledge.On the other hand, students in the process of problem solving activities, through the observation, analysis, comparison, associate, Epiphany, trial and error, such as thinking, constantly improve the ability of mathematical thinking.In the process of solving math problems, A given problem is a pervasive thinking activity, which not only can stimulate students' interest in learning, arouse the enthusiasm of learning, and to cultivate the students' mathematical ability has unique advantages.A given problem can also increase the value in use of math can also be the students problem-solving skills, improve problem-solving ideas, but also broaden their thinking, problem solving promote flexibility and increase their knowledge and wisdom , as well as inter-linkages and application of knowledge.Teacher training students to a given problem can improve the flexibility of thinking, promote wisdom, but also affect the approach students to solve problems in other disciplines, more flexible control link between knowledge and to foster their creativity.
