컴퓨팅 사고 시각화에 의한 정량적 코드 평가 방법 연구

Abstract

The subjects that teach computational thinking in general universities are being designated as compulsory subjects for all enrolledstudents. Through this, students who have learned the software development process by computational thinking are trying tostrengthen their SW convergence capabilities that can be applied to various major fields. Accordingly, research has been conductedon a method of evaluating students’ computational thinking ability. Existing research results include both the understanding of theconcept of computational thinking and the evaluation of the ability to write code, but it is difficult to apply it in practice due to thequalitative evaluation criteria and the evaluation criteria subdivided into code units. Therefore, in this paper, we proposed a method that can quantitatively evaluate students’ computational thinking ability relatively using the additional flow chart result of visualizingthe computational thinking process and the general code result. To this end, a model that visualized the computational thinkingprocess was proposed, and a relative evaluation equation was derived. In addition, in order to help understand the proposed evaluationmethod, a case of obtaining a specific student’s evaluation measurement values from the result of the basic physical computingflow chart and the code result is presented. Finally, a case in which the relative evaluation score was quantitatively derived from theoutcome of a specific student was presented. And, in the course to which this evaluation method was applied, the effectiveness ofthe proposed quantitative relative evaluation method was analyzed based on the results of the satisfaction survey of the evaluationmethod of students and field teachers.
