Evaluation Design Of Information Technology Courses Oriented To Computational Thinkin

Since Professor Zhou Yizhen put forward the concept of Computational Thinking in 2006,many scholars have made a lot of research on the evaluation of computational thinking.In recent years,China has classified computing thinking as one of the four core qualities of information technology curriculum,pushed the research on computing thinking evaluation to a climax,and became the focus of experts,scholars and front-line teachers.However,looking at the research results at home and abroad in this field,it is found that most of the formed Computational Thinking evaluation scope is macro,and it is unable to refine the computational thinking evaluation to each unit or class to effectively evaluate the teaching objectives,resulting in the problem of lack of grasp.Compared with the traditional evaluation model and thinking evaluation system,it is found that the fundamental reason for the current research dilemma lies in the separation and separation of knowledge from thinking in the minds of educational researchers and practitioners.Based on the unified theory of knowledge and thinking and the viewpoint of WSR methodology,this study corresponds Computational Thinking to rational knowledge.On this basis,starting from the upper discipline of information technology "methodology of computer science and technology" and "curriculum standard of information technology in senior high school(2017)",this study focuses on the large concept of discipline and interdisciplinary concept described therein,Extract the core concepts and strategies to be elaborated in the information technology curriculum,and deeply refine the "reasonable" knowledge in the information technology curriculum.Because the knowledge structure involved in the information technology course is too complex,this study takes the field of data and computing as an example to form the core knowledge skeleton of computing thinking in this field.Taking the core knowledge skeleton as the starting point,the knowledge level is stratified with the help of solo classification theory,and the evaluation standard and two-way detailed list are set from the two dimensions of evaluation form and thinking development stage,so as to achieve the goal of systematic evaluation and calculation thinking.At the same time,this study takes the computational thinking evaluation test of high school curriculum as a case,expounds the preparation process of the test in detail,and uses the Delphi method to evaluate the scientificity,objectivity and feasibility of the evaluation method,and strives to provide the reference basis of Computational Thinking evaluation for front-line teaching with this study,so that all teachers can have a basis for teaching and evaluation.
