《义务教育数学课程标准(2011年版)》在课程设计思路中提出了模型思想,~([1])这是与总目标中提出的基本思想相呼应的一个核心概念.模型思想是学习过数学的人所表现出来的最为显著的思维特征之一,即学习过数学的人基于模式的思维能力要强一些.~([2])课堂是学生学习数学知识、发展数学思维的主阵地,那么如何抓住课堂上的机会,发展学生的数学模型思想?本研究立足于一线教学实践,以一节数学课中的三个细节为例,反
The Compulsory Education Mathematics Curriculum Standard (2011 Edition) proposed the model idea in the course of curriculum design, which is a core concept echoes with the basic idea put forward in the general goal. The idea of the model is to study mathematics , One of the most prominent characteristics of thinking, that is, people who have studied mathematics have stronger mode-based thinking ability. (2) Classroom is the main front for students to learn maths knowledge and develop mathematical thinking. Seize the opportunity in the classroom and develop the mathematical model of the students? This study is based on first-line teaching practice, taking the three details in a math class as an example,
