在高中数学教学中,设计适当的情境是非常必要的,这应是大多数教师的共识.设计教学情境的目的当然是为了让学生更好地学习.现今,在核心素养的视角下,设计一个教学情境必须要考虑到有利于数学核心素养的培育与发展,相应的情境要适合于学生学习,激发学生主动思维,从整体上有利于学生的后续发展[1].1教学情境的取材分析数学情境设计应该从学生的数学学习与生活现实出发,其取材不外乎如下两个方面.
In high school mathematics teaching, it is necessary to design the appropriate situation, which should be the consensus of most teachers. The purpose of designing teaching situation is of course to make students better learning. Nowadays, from the perspective of core literacy, Teaching situations must be taken into account conducive to the nurturing and development of mathematical core competence, the corresponding situation should be suitable for student learning, to stimulate students’ active thinking, which is conducive to the follow-up development of students as a whole.1 The analysis of teaching situation Mathematics Situation design should start from the reality of students’ mathematical learning and life, its material is nothing more than the following two aspects.
