《义务教育数学课程标准(2011版)》明确提出,“两能”(分析和解决问题的能力)转化为“四能”(发现和提出问题的能力、分析和解决问题的能力)。在教学时教师要重视对学生“四能”的培养,使学生得到全面发展。如何在数学教学中,运用数学的思维方式引领学生进行思考,增强发现和提出问题的能力、分析和解决问题的能力?以“正比例的意义”教学为例,笔者谈谈几点思考。1.改变呈现形式,从观察中发现问题。根据学生的现实经验和逻辑起点, The Compulsory Education Mathematics Curriculum Standard (2011 Edition) clearly states that “two-energy” (ability to analyze and solve problems) translates into “four-energy” (ability to discover and ask questions, analyze and solve problems) ). In teaching, teachers should pay attention to the cultivation of students “four energy ” so that students can develop in an all-round way. How to lead students to think, to enhance the ability to find and ask questions, and to analyze and solve problems in the teaching of mathematics by using the way of thinking in mathematics? Take the teaching of “proportionality” as an example, I will talk about some thoughts. 1. change the presentation, found from the observation of the problem. According to the students' practical experience and logical starting point,
