基于“体验学习圈”的计算思维培养模型研究

Research on the Computational Thinking Cultivating Model based on“Experience Learning Circle”

文章首先分析了计算思维与"体验学习圈"的内涵,并将计算思维解构为"定义问题、抽象特征、优选算法、纠错迭代"四大核心能力。随后,文章根据Scratch体验式教学的"情境体验、反思观察、建立模型、行动分享"四个环节,构建了基于"体验学习圈"的计算思维培养模型。最后,文章将此模型应用于以"未来智能教室"为主题的教学活动中,并分析了其具体的教学实施过程和教学成效。基于"体验学习圈"的计算思维培养模型的提出,为实现计算思维核心能力培养与Scratch体验式教学环节的耦合提供了路径,并可为中小学计算思维教学实践的有效开展提供参考。

This paper firstly analyzed the connotations of computational thinking and"experience learning circle",and deconstructed computational thinking into the four core competences of"definition problem,abstract feature,optimization algorithm,error correction and iteration".Subsequently,according to the four steps of Scratch experiential teaching of"situational experience,reflective observation,model building and action sharing",this paper constructed the computational thinking cultivating model based on"experiential learning circle".Finally,this model was applied in the teaching activities with the theme of"future intelligent classroom",and further its specific teaching implementation process and teaching effect were analyzed.The proposal of the computational thinking cultivating model based on"experiential learning circle"could provide a path for the coupling of the computational thinking core competences cultivating and Scratch experiential teaching steps,and provide reference for the effective implementation of teaching practice of computational thinking in primary and secondary schools.
