Most of the courses that teach the Python programming language are liberal arts courses that all students in general universities must complete. Through this, non-major students who have learned the basic programming process based on computational thinking are strengthening their convergence capabilities to apply SW in various major fields. In the previous research results, various evaluation methods for understanding the concept of computational thinking and writing code were suggested. However, there are no examples of evaluation problems, so it is difficult to apply them in actual course operation. Accordingly, in this paper, a Python basic programming curriculum that can be applied as a liberal arts subject for non-majors is proposed according to the ADDIE model. In addition, the case of evaluation problems for each Python element according to the proposed detailed curriculum was divided into 1st and 2nd phases and suggested. Finally, the validity of the proposed evaluation problem was analyzed based on the evaluation scores of non-major students calculated in the course to which this evaluation problem case was applied. It was confirmed that the proposed evaluation problem case was applied as a real-time online non-face-to-face evaluation method to effectively evaluate the programming competency of non-major students.

2015 개정 교육과정을 통해 소프트웨어 교육의 일환으로 프로그래밍 교육이 초등학교 정규교과에 도입된다. 프로그래밍 교육이 문제해결력에 미치는 영향에 대한 분석을 통해 효과적인 교수 학습 방법이 제시될 수 있다. 본 연구에서는 엔트리와 엔트리용 센서보드를 활용한 5차시 분량의 학습 프로그램을 개발하고 그것을 적용한 수업을 실시하였다. 수업 전 후에 문제 해결 검사도구를 활용하여 학생들의 감마파와 뇌파집중 지표의 변화를 측정하고 분석하였다. 이를 통해 효과적인 프로그래밍 교육의 필요성을 제안하였다.

The purpose of this study is to develop and validate assessment tools and to analyze their applicability in problem solving programming education for college students of teacher training college. For this purpose, we have redefined the area of computational thinking and detail elements from the viewpoint of problem solving programming, and developed paper type inspection and self - report questionnaires to evaluate them. The reliability and validity were analyzed by applying the evaluation tool developed for the actual college students of teacher training college. Through this study, it was confirmed that the paper type inspection and self - report questionnaires developed in this study can be used as a tool to computational thinking assessment.

The goal of this study is to assess the effects of Scratch programming classes on preservice teachers by using computational thinking and cognitive evaluations based on Bloom's taxonomy. To pursue this research goal we measured preservice teachers' programming skills using cognitive evaluation items based on Bloom's taxonomy after preservice teachers took one-semester Scratch programming course. In addition, a survey focused on computational thinking (CT) concepts, CT practices, and CT perspectives was conducted. We also conducted artifact-based interviews to unpack preservice teachers' experiences of working on team projects and analyzed their experiences qualitatively. The results of this study are meaningful because we assessed preservice teachers' experiences comprehensively with both quantitative and qualitative methods. In addition, this study provides us with implications for evaluation perspectives in designing programming courses for preservice teachers by adopting Bloom's taxonomy scheme.

As the computer becomes pervasive in everyday life, the programming arises as an essential technique. To support the education of programming, Republic of Korea has launched a plan to develop the official courses of programming by 2018. However, the programming education in Korea tends to be difficult and the students easily lose their concentration since most of programming languages are based on English. This paper proposes a Korean programming language called Saesark to promote the effective programming education for Korean students. Saesark has been developed based on Java, which supports the object-oriented programming and the lambda expressions. In order to evaluate the educational suitability of Saesark, we compared it with other Korean programming languages in three respects: syntactic features, IDE support, and error messages in Korean. According to the comparison, Saesark is revealed more suitable than other languages. Specifically, the IDE features and the error messages in Korean are expected to be mostly valuable in educating novice programmers.

In order to improve computational thinking, elementary schools have been using 'Scratch' to provide basic programming education. However, the study on evaluation of computational thinking is at an early stage. Therefore, this study evaluated the conceptual level of computational thinking using the scratch code analyzing. For this, Dr. Scratch was used to analyze 179 scratch projects. The results showed that the conceptual level of computational thinking of most elementary students was at the developing level, and that it varied according to gender and production style, showed the lowest level of logic and abstraction, and improved computational thinking during programming. This study is meaningful in that it provides implications for the improvement of teaching methods and self-directed evaluation in learning.

고도의 지식기반사회에서는 사고력과 문제해결력을 길러주는 프로그래밍 교육이 필요하며 이를 초등학교 교육과정부터 도입해야 한다는 여러 연구들이 있었다. 본 연구에서는 그러한 프로그래밍의 기초능력을 배양하기 위하여 프로그래밍 변수 개념 형성을 위한 효과적인 학습 모형을 구안하고자 하였다. 구체적 조작활동을 통해 인지를 형성하는 초등학교 아동들에게 LOGO 프로그래밍 활동이 적합하다는 선행연구를 토대로, 영어에 미숙한 아동들을 고려하여 MAL-LOGO 환경을 선택하였으며, 프로그래밍 학습요소 중 변수 개념 형성을 위한 학습요소를 추출하고, 교수-학습 프로그램을 계획하였다. 인지적 모니터링 전략(cognitive monitoring strategy)을 발달시킬 수 있는 안내된 발견식 교수법(guided instruction teaching method)을 기반으로 교수-학습 모형을 구안 적용한 후, 사전 사후 평가를 통해 그 효과를 검증하였다.

Software developing education teaches students computer programming, which allows them to actively use IT and talk to computers. In this study, we analyzed computer science curriculum in the United Kingdom, the United States, India, and Estonia. In order to teach 1st - 9th grade students computer programming, we suggested the learning objectives, instructional design, and evaluation methods in software developing education focusing on Information Science. The objectives were divided into four phases, which were determined by age and grade level. Then, we determined 2-3 outcomes for each phase.

Scratch is Educational Programming Language, and it has been widely used in Elementary school SW Education. Many studies show that Scratch education is helpful for students' computational thinking and problem solving. However, the lower grade students use scratch less than the higher grade students, and the higher grade students have difficulty in understanding basic programming principles such as sequence, repetition, and condition. Therefore, in this study, we developed Scratch electronic blocks and programming education curriculum. We had classes for 2nd grade and 6th grade students, and it was confirmed that the score of 2nd grade students' interest about programming increased from 3.28 to 3.58 and 6th grade students' interest increased from 3.41 to 4.09. As a result of the programming basic principles understanding assessment, 84% of the 2nd grade students solved more than 7 of the 9 questions and 62% of the 6th grade students solved more than 7 of the 9 questions.
