《数学新课程标准》提出,数学教学要紧密联系学生的生活环境,从学生的经验和已有知识出发,创设有助于学生自主学习、合作交流的情境。在数学教学中,创设问题情境不仅可以培养学生的学习兴趣和探索精神,还可以很好地提高教学质量。本文中,笔者提出了创设有效问题情境的五种方法。一、通过生活实际创设问题情境有些数学概念是从实际生活中抽象出来的,教师要从实际出发,创设合理的问题情境,引导学生观察、思考和总结,从而提炼出数学问题,培养学生的创新能力。
The New Curriculum Standard of Mathematics states that mathematics teaching should be closely linked with the living environment of students, starting from the students ’experiences and existing knowledge, and creating situations conducive to students’ independent study and cooperation and exchange. In mathematics teaching, creating problem situations can not only cultivate students’ interest in learning and exploration, but also improve teaching quality. In this article, I propose five ways to create an effective problem situation. First, through the actual creation of the problem situation Some mathematical concepts are abstracted from the actual life, teachers should start from the reality, to create a reasonable problem situations, to guide students to observe, think and summarize, so as to extract mathematical problems and cultivate students’ innovation ability.
