新课程改革已由三维目标向学科核心素养目标转变。直观想象是体现学生数学核心素养的重要维度。所谓直观想象是指借助几何直观和空间想象感知事物的形态与变化,利用图形理解和解决数学问题的过程。主要包括:借助空间认识事物的位置关系、形态变化与运动规律;利用图形描述、分析数学问题;建立数与形的联系,构建数学问题的直观模型,探索解决问题的思路。本文就初中数学教学对学生直观想象能力的培养提出自己的思考和教学建议。
The new curriculum reform has changed from the three-dimensional goal to the subject core literacy goal. Intuitive imagination is an important dimension that embodies students’ core literacy. The so-called visual imagination refers to the use of geometric intuition and spatial imagination perception of things shape and change, the use of graphics to understand and solve mathematical problems process. Mainly include: the use of space to understand the location of things, morphological changes and movement rules; the use of graphic description, analysis of mathematical problems; establish the relationship between number and form, build mathematical models of intuitive models to explore ways to solve the problem. In this paper, junior high school mathematics teaching on students’ ability to develop visual imagination put forward their own thinking and teaching suggestions.
