指向高中生直观想象素养的教材对比分析——以“人教A版”和“鄂教版”必修中函数相关内容为例

A Comparative Analysis of Teaching Materials for High School Students’ Visual Imagination Literacy—Taking the Function Related Content in the Compulsory Courses of “Human Education A Edition” and “Hubei Education Edition” as an Example

摘要: 《普通高中数学课程标准(2017版)》提出了六大数学学科核心素养。直观想象是六大数学核心素养要素之一，其在培养学生逻辑思维能力、培养学生建模能力、发展学生空间观念等方面有着重要应用。本文从数量分布、直观想象素养水平、呈现位置和选材情境对涉及直观想象的内容进行分析，并对教师的教学提出如下建议：在教学过程中，教师要多提供机会让学生去观察、去想象，引导学生从空间的角度去分析，以此发展学生的直观想象能力，提高学生的数学核心素养。

Abstract: The Standard of Mathematics Curriculum for Senior High School (2017 edition) puts forward six core qualities of mathematics subjects. Intuitive imagination is one of the six core qualities of mathematics, which has important applications in training students’ logical thinking ability, modeling ability and spatial concept. This paper analyzes the content involving intuitive imagination from the perspective of quantity distribution, visual imagination literacy level, presentation location and material selection situation, and puts forward the following suggestions for teachers’ teaching: In the teaching process, teachers should provide more opportunities for students to observe and imagine, and guide students to analyze from the perspective of space, so as to develop students’ intuitive imagination ability and improve students’ core mathematical literacy.
