1 苏教版小学数学画图策略教学的初探 Preliminary for Jiangsu elementary school mathematics teaching on drawing strategies 【摘要】在数学中解决问题的策略有很多种, 其中画图策略是一种最基本最常用的解题策略。画图策略在苏教版四年级才出现,但从一年级开始就已经渗透。小学生年龄尚小,他们正出于形象思维向抽象思维过渡的阶段。所以抽象的数学问题对他们而言难度较大,运用画图的方法恰好能把抽象的问题直观的呈现出来, 这样就把复杂的数学问题变得简单,能够方便学生找到解决问题的关键, 解决难题。所以指导学生运用画图的策略,不仅适应他们的认知发展特点,也有助于他们提高解决问题的能力, 画图策略的学****极为重要。目前很多有关画图的研究都是从学生学****情况和教学出发的,本研究从教材出发,以苏教版为例,初步探索小学数学画图策略的教学。这里我罗列了教材中体现画图策略的有关内容,分析其中的优点和不足,并基于此提出促进画图策略教学的建议。画图策略的教学应该从低年级开始,系统地渗透。【关键词】画图策略;解决问题;教材;认知能力 Abstract: There are many kinds of problem solving in mathematics method, the drawing strategy is one of the most basic and mon problem solving strategies. Drawing strategy appears in Su Jiaoban the fourth grade, but from the first grade to have rated. Primary school age is still small, they are out of image thinking to abstract thinking transition stage. So the abstract mathematics questions difficulty for them is larger, with drawing method that can make abstract problem visual picture, so plex mathematical problems e simple, can be convenient for students to find the key to solve the problem, solve the problem. So to guide students to use the drawing of the strategy, not only adapt to the characteristics of their cognitive development, but also help them to improve their ability to solve problems, as an important strategy to learn drawing. At present many of the drawing research is from the student learning and teaching, this study from the starting materials, the Jiangsu Education Edition as an example, a preliminary exploration of primary school mathematics teaching strategy drawing. Here I list the contents reflect the drawing strategy textbooks, analyze the merit and ings, and puts forward suggestions based on this drawing teaching strategies. Drawing teaching should start from low grade infiltrating, system. Keywords: drawing strategy ; solve the problem ; the teaching material ; Cognitive ability 2 目录 1引言…………………………………………………………………………………… 3 问题研究的背景……………………………………………………………
