초록
프로그래밍 언어를 활용한 데이터 시각화는 처리하는 데이터 양, 처리 시간, 유연성에서 효율성과 효과성을 향상시킬 수 있으나 프로그래밍에 익숙해지기 위해 연습이 필요하다. 이에 본 연구에서는 프로그래밍 자동 평가 시스템에서 데이터 시각화를 연습하기 위한 공공데이터 기반 문제은행을 개발하였다. 공공데이터는 교육과정에서 제시한 주제로 수집하였으며 학습자가 데이터 시각화하기에 적절한 형태로 가공하였다. 문제는 다양한 데이터 시각화 방법을 학습하기 위해 수학교육과정과 연계하여 개발하였다. 개발한 문제는 전문가 검토 및 파일럿 테스트를 실시하였으며문항의 수준, 데이터 시각화를 통한 수학 교육의 가능성을 확인하였다. 하지만 학생에게 흥미가떨어지는 주제라는 의견을 받았으며 이를 보완하기 위해 학생이 중심이 되는 데이터를 활용하여추가로 문항을 개발하였다. 개발한 문제 은행은 초등학교 정보영재 또는 중학교 이상에서 파이썬을 학습한 경험이 있는 학생이 데이터 시각화를 배울 때 활용될 수 있을 것으로 기대된다.
Abstract
Utilizing programming languages for data visualization can enhance the efficiency and effectiveness in handling data volume, processing time, and flexibility. However, practice is required to become proficient in programming. Therefore public data-based the problem bank was developed to practice data visualization in a programming automatic assessment system. Public data were collected based on topics suggested in the curriculum and were preprocessed to make it suitable for users to visualize. The problem bank was associated with the mathematics curriculum to learn various data visualization methods. The developed problems were reviewed to expert and pilot testing, which validated the level of the questions and the potential of integrating data visualization in math education. However, feedback indicated a lack of student interest in the topics, leading us to develop additional questions using student-center data. The developed problem bank is expected to be used when students who have learned Python in primary school information gifted or middle school or higher learn data visualization.
