构建数学模型 推进深度思考——以数学广角教学为例

Build a Mathematical Model to Promote in-depth Thinking

模型思想是《义务教育数学课程标准(2011版)》的十大核心概念之一。课标指出:模型思想的建立是学生体会和理解外部世界的基本途径。作为教师应有意识地培养学生构建模型的思想,提高学生解决实际问题的能力。因此,激发学生建模需求,引导学生猜测、验证、应用、完善拓展模型,才能逐步培养学生的模型思想,同时在探究过程中推进学生深度思考。

Model thinking is one of the ten core concepts of"Compulsory Education Mathematics Curriculum Standard(2011 Edition)".The course standard points out:the establishment of model thinking is the basic way for students to experience and understand the external world.As a teacher,we should consciously cultivate students’model thinking and improve their ability to solve practical problems.Therefore,only by stimulating students’modeling needs and guiding students to guess,verify,apply,and improve and expand models can they gradually cultivate students’model thinking and at the same time promote students’in-depth thinking in the process of inquiry.
