7차 교육과정은 응용소프트웨어를 얼마나 잘 다루는지와 같은 컴퓨터를 도구적 활용을 중점으로 구성되었다. 컴퓨터 과학의 기본원리를 적용하여 문제해결능력을 신장시키고 이를 구현하기 이한 체계적인 교육의 필요성이 제기되어 2007년 개정 교육과정에서 문제해결방법과 절차라는 대영역이 포함되었다. 정보과목 문제해결방법과 절차 영역에서 다양한 문제를 이해 분석하여 알고리즘을 설계하고 구현하는데 있어 원활한 교수학습을 위한 다양한 방법과 도구들에 대한 연구가 요구되고 있다. 본 연구는 창의적 문제해결 향상에 효과적인 프로그래밍 언어들은 상용소프트웨어들의 비용부담과 언어적 문법, 에러발생에 대한 해결에 비중이 높아 학습자가 겪는 인지적 부담을 감소 할 수 있는 EPl(Educational Programming Language)인 Scratch 프로그래밍으로 창의적 문제해결력 향상을 위한 교수학습 모형을 개발하였다.

본 논문에서는 비전공자 대상의 학습자 눈높이에서 흥미와 재미를 유발하고, 실제 비전공자의 컴퓨팅사고력(Computational Thinking)을 향상시키는데 콘텐츠에 따라 학생의 관심도가 달라질 수 있다는 분석결과를 보여준다. 기존의 SW교육 시스템(EPL: Education Programming Language)의 단점인 실행 중심의 SW교육 시스템에서 벗어나 실제 생활에서의 기초적인 컴퓨팅 사고 관련 예제로서 모델별 단계적 접근을 시도하면서, 실제 생활 속 컴퓨팅 사고력 기반의 문제해결력을 높일 수 있도록 피드백 방식이 비전공자 SW교육에 끼치는 영향력을 확인하였다.

The purpose of this study is to analyze the effect of SW education applying design thinking on the creativity of elementary school pre-service teachers. We conducted research on 22 elementary school pre-service teachers who applied for a lecture on elementary computer education at a university in Jeju city. The pre-service teachers who did not have basic understanding of SW education and basic knowledge about scratch program which is an EPL tool for research. Therefore, we had time to learn the basic education of SW education and the basic functions of the scratch program over 18 periods before the pre-test of creativity. After conducting pre-test of creativity and conducting SW education applying design thinking over 21 hours, we conducted post-test of creativity. As a creativity test tool, TTCT pattern test forms A and B of Torrance were used. As a result of the verification, it was found that SW education applying design thinking was effective in improving creativity of elementary school pre-service teachers.

Educational Programming Language (EPL) should be learner-friendly and easy to use. Dolittle, an object-oriented educational programming language (EPL), offers programming environment which can be programmed in Korean(Hangul). However, since some Dolittle commands are not appropriate to elementary and middle school students, it shows limitations for learners to express programming process. In this paper, we developed a set of 1:n multi-reserved words which are able to program with Korean linguistic characteristics as well as considering learners' differences, preferences, and applicable areas. The conclusion in the paper showed that programming with this 1:n multi-reserved words helped learners concentrate on problem solving regardless of the reserved words.

Since the problem-based learning (PBL) shows the effectiveness of self-directed learning ability and internalization of learning motivation in the process of solving real problems, studies on PBL and application cases are actively pursued in the university education. This study analyzed the effects of PBL on the academic achievement and computational thinking in a non-SW major students' programming course. The programing course was divided into the PBL class and non-PBL class, and at the end of the classes, the scores of the exams and the results of questionnaires about the educational effectiveness and computational thinking were analyzed. As a result, the students in the PBL class, compared to those in the non-PBL class, showed significantly higher scores in the areas of the algorithm implementing skill, self-directed learning, problem solving ability, and continuous learning motivation.

This paper propose to use a new educational programming language, Scratch, to help students' programming study. For this purpose, a course has been developed which consists of (1) strategies to motivate students and (2) Creative Problem Solving (CPS) teaching model to improve their problem solving abilities. We experimented the course with sixth-grade elementary students for 4 weeks and we could observe that the Scratch programming learning helps motivating students and improving their problem solving abilities. Based on this observation, we believe that Scratch programming can be an alternative for current programming education in elementary schools.

This study is about development and application of a curriculum to implement physical computing education in an online environment for pre-service teachers. First, a 15-week software and physical computing curriculum was designed according to the ADDIE instructional design model. As a tool that can be used online, education was conducted on a program using various sensors using Pocket Code, an EPL based on a smartphone. As a result of the application of the program, Personal efficacy, Pedagogical knowledge, Technology teaching content knowledge, Result expectation, and Student belief were all significantly improved. In the software attitude part, Software interest and Software value part increased significantly, and the Perception of software engineers did not change. In general, in the case of physical computing, it is difficult to execute in an online environment because it involves a lot of manipulation activity. Through various studies that can continue education in a non-face-to-face environment or a blended environment in the post-corona era, it is hoped that it will be possible to provide a high-quality curriculum to pre-service teachers in charge of future education.

Computer Science Education has to be dynamically changed due to a change of information technology. This study aims to present the direction of development for computer science education according to compare a report of KEDI; Korean Educational Development Institute, twenty years ago with our latest investigation. In this research, nowadays the personal computer diffused at most home. Home is the main environment for students to use computer. Students demand new computing curricula and teaching method. The global tendency of computer science education focuses on the improvement of problem solving ability. According to our investigation, most students hope to learn the new computing skills through game-based learning. We present the unplugged teaching methods and simulation-based learning using EPL(Educational Program Langage). Of course it's important to be applied to school now. And it can be achieved just by national efforts alone.

In this paper, we propose to investigate the existing SW education related studies and to collect the total effect size for the improvement of computational thinking(CT) through meta-analysis and to confirm the effect size according to various variables. So, we have objectively identified and generalized the practical effects of SW education on the various variable. The results of the meta-analysis showed that 1) the overall effect of SW educational activities on CT improvement was 'Hedges' g=0.643', so SW educational activity can get a CT improvement of about 24% over other educational activities. 2) EPL is a SW teaching-learning method that greatly improves students' CT. 3) Since SW education can be guaranteed to improve CT among elementary school students and university students, essential SW education for these should be further promoted. And it was found that SW education activity were more effective for CT improvement in small cities & rural areas than big cities, but the cause was not identified, so further study will be required.
