Scratch在小学数学中的应用——以《长方形的周长》为例

Application of Scratch in Primary School Mathematics—Take"The Perimeter of a Rectangle"as an example

近年来,少儿编程在基础教育中提及的频率越来越高。Scratch作为一款专为儿童学习的图形化编程软件,因其形象直观、简单易学、功能丰富的特点,深受广大一线教师及青少年的喜爱。小学数学作为一门基础学科,是培养学生逻辑思维、创新能力的重要载体。基于Scratch的优势,如何将其与小学数学相结合来提高学生数学应用能力、问题解决能力等,是我们需要积极探索并付诸实践的课题。该文以小学三年级数学《长方形的周长》知识点为例,实践之后学生学习积极性得到提高,课堂效果有所改善。最后,笔者提出相应教学策略,希望能为一线教师提供启发与借鉴。

In recent years,children's programming has been mentioned more and more frequently in basic education.As a graphical programming software designed for children to learn,Scratch is deeply loved by front-line teachers and young people because of its intuitive image,easy learning,and rich functions.As a basic subject,elementary school mathematics is an important carrier for cultivating students'logical thinking and innovation ability.Based on the advantages of Scratch,how to combine it with elementary school mathematics to improve students'math application ability and problem-solving ability is a topic that we need to actively explore and put into practice.This article takes the knowledge points of the third grade mathematics"Rectangle Perimeter"as an example.After practice,students'learning enthusiasm has been improved,and the classroom effect has improved.Finally,the author proposes corresponding teaching strategies,hoping to provide inspiration and reference for frontline teachers.
