如何提高45分钟的效益是每一个教师必须研究的课题.数学新课程标准倡导“创设问题情境——建立数学模型——解决数学问题”的教学模式,其中“创设问题情境是否有效”是这一节数学课能否高效的关键.在课堂教学活动中,教师根据不同的教学内容和教学对象精心创设问题情境,不但可以完善学生的认知结构,激发学生的探究欲望,强化学生的学习动机,发展学生的创新意识,也是全面提高数学课堂教学高效性的重要途径之一.本人就数学教学中如何创设数学化问题情境来构建有效数学课堂,谈谈自己的一些做法和拙见.
How to improve the benefit of 45 minutes is a must for every teacher.Mathematical new curriculum standards advocate the teaching mode of “creating problem situation-establishing mathematical model-solving math problem”, in which "creating problem situation is valid Is the key to whether mathematics lesson can be effective in this section.In the classroom teaching activities, teachers carefully create the problem situation according to different teaching contents and teaching objects, which can not only improve students ’cognitive structure, stimulate students’ inquiry desire and strengthen students Learning motivation and developing students’ innovative awareness are also one of the most important ways to improve the efficiency of mathematics classroom teaching.About how to set up a mathematical problem context in mathematics teaching to construct an effective mathematics classroom and talk about some of our own practices and my humble opinion.
