数学是小学教育基础学科之一,也是教学的重点和难点。相关调查研究结果显示,不少小学数学教师仍然运用传统填鸭式教学方式,学生被动地听讲,师生之间几乎很少互动,学生兴趣较低,影响教学效果。问题情境就是在新课程改革大环境下提出的,能较好地发挥学生创造性和主动性,唤醒大脑记忆中的数学认知。本文则从开放化、悬疑化及故事化三种问题情境着手分析其具体应用,望给予小学数学教师提供教学参考。
Mathematics is one of the basic disciplines of primary education, but also the teaching of the key and difficult. Relevant survey results show that many primary school mathematics teachers are still using the traditional cramming teaching methods, students passively listen, almost no interaction between teachers and students, lower interest of students, affecting teaching effectiveness. The problem situation is put forward under the environment of the new curriculum reform. It can give full play to students' creativity and initiative and awaken the mathematical cognition in brain memory. This essay analyzes its specific application from the openness, suspensefulness and story-telling situations, and hopes to provide primary school mathematics teachers with teaching reference.
