Focus On Evaluation Design Research In The Field Of Information Technology Tools For Computational Thinking Training

In recent years,computational thinking has gradually attracted people's attention.In the Information Technology Curriculum Standards for Ordinary Senior High Schools issued in 2017,computational thinking is regarded as one of the core qualities of information technology discipline.As an important core quality of information technology curriculum,the evaluation of computational thinking has attracted much attention.It is found that the existing evaluation of computational thinking is mostly process-oriented,and the evaluation cycle is too long to accurately evaluate the development of students' thinking.Therefore,it is of great significance to design evaluation standards of computational thinking with high precision oriented to specific knowledge fields for the practical training of computational thinking.In addition,although the field of information technology tools is an important part of information technology discipline,there are few studies focusing on this knowledge field,which leads to the landing training of thinking is particularly difficult.Based on this,this study focuses on the evaluation of information technology tools for the cultivation of computational thinking,aiming to design a set of systematic feasible and highly precise evaluation criteria for computational thinking in the field of information technology tools.In this study,literature research method and Delphi method are used to deeply explore and analyze the evaluation research in the field of information technology tools focusing on computational thinking.Firstly,the core knowledge framework in the field of INFORMATION technology tools is designed by combining the information technology curriculum standard and The description framework of computing thinking of Bonan.The framework consists of computing concept and computing strategy.The computing concept includes six kinds of information technology tools,layers,sequences,efficiency,security and correctness.The computing strategies include divide and conquer,overall planning,visualization,compromise,reuse and encapsulation.Then,the evaluation criteria are determined by using the five levels of prestructure level,single-point structure level,multi-point structure level,related structure level and extended abstract structure level in SOLO classification theory.In this paper,we design different kinds of thinking evaluation criteria and different knowledge range of thinking evaluation criteria and explain them with the corresponding cases in order to clarify the thinking of the compilation of computational thinking evaluation questions in the field of information technology tools.Finally,this study combined the core knowledge framework of information technology and the main knowledge of information technology in the middle and high schools,designed a set of evaluation questions of computational thinking in the field of information technology tools in the middle and high schools with the help of SOLO theory,and verified and improved the scientificity of the test papers with the Delphi method.
