情境是联系生活现实与数学逻辑之间的重要桥梁,是将凝固的课程知识转化为鲜活的生命形态的重要载体。探究情境的设置,不但能激发学生的学习兴趣,而且更重要的是调动学生的相关经验,促进学生对所学知识的意义建构,同时还有利于揭示数学与现实世界的桥梁,让学生逐渐感悟学习数学的实用价值,培养学生的数学应用意识和能力。作为教师,要合理处理教材,重组教学内容,通过蕴含数学知识的问题背景,引导学生思维,使学生进入一种“心求通而未得,口欲言而不能”的境界。
Situation is an important bridge between the reality of life and mathematical logic, and an important carrier for transforming frozen curriculum knowledge into fresh life forms. To explore the setting of situation not only can arouse students ’interest in learning, but more importantly, to mobilize the relevant experience of students and promote the construction of the meaning of students’ knowledge. Meanwhile, it also helps to reveal the bridge between mathematics and the real world, Learn the practical value of mathematics, develop students’ awareness and ability to use mathematics. As teachers, we should deal with the teaching materials reasonably, reorganize the teaching contents, guide the students’ thinking through the background of the problems that contain the mathematical knowledge, and make the students enter a realm of seeking truth from the heart but not speaking.
