Object Oriented Programming Languages including Java require Object-oriented thinking first for programming. However, for Korean students it is not easy since they are fully accustomed to Korean language which does not have the Object-oriented concept. This paper proposes a way of teaching the Object Oriented Languages to Korean students. It explains first how to organize our thoughts in Object-oriented way, and then how to express the thoughts with the languages.

Programming novices have various difficulties when they learn C language for the first time. Novices have a large burden for understanding of a C language grammar, and have a tendency to focus on the grammar rather than problem solving. Moreover, it requires programming domains to arouse student's interest for software development. This paper presents a programming environment for C languages education focusing on a problem solving. To this end, this paper defines Tiny-VPL that is a simple visual programming language for NXT robot programming and presents robot programming environment using Tiny-VPL. This paper also presents an environment for NXT robot programming using Mini-C language which is a subset of C language. For the purpose of helping to understand the C syntax and semantics, the visual and interactive conversion system of Tiny-VPL to Mini-C is provided. Our programming environment can arouse student's interest through robot programming and can be used effectively for C language education focusing on problem solving with graphical and interactive conversion of the visual language Tiny-VPL to the textual language Mini-C.

정보영재교육 등을 통해 초등학생을 위한 프로그래밍 교육이 활성화되고 있다. 베이식 언어는 초등학생이 실습하기 용이한 컴퓨터 언어이지만 명령어가 영어로 되어 있어 한글로 프로그래밍 할 수 있으면 더욱 원활하게 사용될 수 있다. 이에 본 연구에서는 초등학생이 사용하기 쉬운 한글 기반의 베이식 프로그래밍 실습 시스템을 구현하고자 한다.

In computer education area, abstract thinking has played a positive role in programming ability, and language experience has also affected the ability. However, most of the studies were empirical. The practical research about the relation analysis between abstract thinking and programming ability has rarely been performed. Among various types of programming abilities such as coding, debugging, and reading, this paper focused on program understanding. We analyzed the affection relation on program understanding and the interaction effect between abstract thinking level and language familiarity. We surveyed 376 high school students on their abstract thinking levels, language familiarity, academic achievement, and the program understanding abilities of C and Scratch. From the research, we knew that the abstract thinking level played an important role in understanding the iterative program for the male students. In addition, if the students had the experience on other programming languages before entering high schools, then there was an interaction effect between abstract thinking level and program language familiarity.

As the SW-centered society has emerged, SW-based problem-solving capabilities is emphasized in all areas of society. It is a trend that universities are obliged to do SW basic education for non-majors students and they are carrying out programming education. This study derives grammatical elements based on conciseness, generality, and efficiency among the design principles of programming language and based on it, compares and analyzes visual programming language and diagramming language. As a result, the efficiency of Raptor is more powerful than Scratch in the simplicity and generality, and the same tendency can be confirmed in the result of the learner's obtained in programming lesson. We hope that this study will contribute to the design and implementation of programming education based on features of programming language.

Current computer education is difficult to educate basic concepts and principals of the computer science because the 7th curriculum of computer education is focused on the application of software. According to the ACM K-12 report about the computer science education model, current computer education is taking the wrong way and we should put the highly priority on the education of the fundamentals through programming languages for a better computer education oriented to the computer science. This paper introduces a new object-oriented educational programming language "Dolittle". The design principals of Dolittle are simple syntax of Korean, incremental programming, text based programming, aliasing of function, and object-oriented programming. Being applied to middle school classes, we can confirm that Dolittle is easy to learn, and gives rise to high interest and keeps interest through a course, and also is of great practical use in class for programming novice.

Recently, domestically and abroad, programming education has become more important and this increase has been recognized. And it needs a certain criteria for a selection of programming tools because there are various educational programming tools coming out. Thus, we tried to develop a criteria on the selection of educational programming language for a novice programmer and K12 students and verify its validity. So we established 4 areas and 28 items for selection criteria on educational programming language. Additionally, we carried out delphi survey and analyze for validity verification on selection criteria established. As result of carrying out of these processes, we developed 4 areas of selection criteria. Finally we have chosen 19 selection criteria and excluded 9 criteria items which are not sufficient with validity criteria through delphi survey.

The programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, but it requires mathematical knowledge and logical thinking skills, so that many local private university and college students with low basic skills are having difficulties learning it. This problem occasionally causes SW-major students to lose interest and confidence in their majors during the introductory course of programming languages; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C-language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C-language, and developed the examples of Scratch for exercising the concepts. In addition, we designed an instructional model, by which the programming concepts are first learned through Scratch and then C-language is taught, and conducted an experiment on the SW-major freshman students of a local private university to verify the effectiveness of the model. In the situation where SW education is becoming common, we expect that this study will help programming language education of security IT students.
