Research On Evaluation Design In The Field Of Communication Network Focusing On The Cultivation Of Computational Thinking

Computational thinking has become one of the core qualities of information technology courses,and the evaluation of computational thinking has attracted much attention,which has attracted more and more researchers to study the evaluation system.Therefore,this study will take the evaluation of ordinary high school students' Computational Thinking as the purpose,build a computational thinking evaluation system,and take the preparation of test questions as an example.Firstly,through literature retrieval,this study found that great importance was attached to the cultivation and evaluation of computing thinking in senior high school.Based on this,this study focused on the evaluation of computing thinking in the field of communication network in information technology.However,it was found that the evaluation system of computing thinking constructed at home and abroad did not face different levels of classroom,unit,semester and stage,The evaluation of computational thinking is not detailed to all levels of this field.Finally,this study builds a three-dimensional and comprehensive evaluation system of Computational Thinking Based on the core knowledge framework.Secondly,this study uses the literature research method and Delphi method to construct the core knowledge skeleton in the field of communication network,and designs the evaluation standards of computing thinking in different knowledge types and levels according to the skeleton,so as to form the evaluation test of computing thinking in the field of communication network in Senior High School.Thirdly,the test questions compiled in this study mainly come from the existing test questions and self-made test questions.The two are combined to form a complete set of test questions to evaluate students' Computational Thinking,and the complete test questions are used to verify their scientificity and rationality by Delphi.Through the qualitative opinions of five front-line teachers,this set of test questions are modified and improved to form the final version of the test questions.Finally,the evaluation system of computing thinking in the field of communication network is formed.According to the core knowledge framework and solo classification theory constructed by this research,the evaluation standards of computing thinking in different knowledge types and different levels in this field are designed,and their computing thinking is evaluated from the two levels of knowledge points and thinking structure,so as to form the test questions of computing thinking evaluation in senior high school.
