【Abstract】Mathematics occupies an important position in the education system of elementary schools. As one of the important subjects for training students' logical thinking ability and practical ability,whether various teaching methods can be effectively used to cultivate students' mathematics ability has been highly praised by many teachers. attention. With the continuous advancement of the new curriculum reform,the application of situational teaching method has become wider and wider. Many teachers have begun to realize the positive significance of creating problem situations for students' learning. This article briefly analyzes the current primary school mathematics teaching work in creating effective problem situations In terms of problems,focus on the creation of effective problem situations in the classroom,and propose corresponding measures.

新课改对小学数学提出了更高的要求,也需要教师具备更高的专业能力和教学水平,传统的数学教学方式通常强调教师讲解知识,忽略了学生主体地位,教师必须转变自身教学理念,解决传统数学教学模式下存在的诸多问题。创设问题情境是提高小学数学教学质量的重要保障,教师必须根据不同教学内容选择适当的问题情境创设方式,使学生能够通过问题情境提升数学知识运用能力。
1.创设有效问题情境的积极意义
(1)有利于激发学生学习兴趣
兴趣是学生发展学习的不竭动力,也是最稳定的学习动机,但由于小学生年龄小、天性活泼他们总是对新奇的事物充满好奇心和求知欲,问题情境的创设可以给学生带来不同的体验。由于受到了应试教育的消极影响,教师在传统教学中会采取单一的讲授法来进行,这导致师生没有积极互动,学生也只是机械地接收知识,这样的教学会导致学生对数学的学习兴趣难以得到激发。……
