Programming education can improve problem-solving skills and logical thinking required in a knowledge-based society. However, most conventional programming education spent more time to acquisition of command language and coding process rather than improvement of problem-solving skills and logical thinking, for using programming languages based on foreign language and learners have appeared to lost interest easily. To solve these problems in this paper, interest in programming study was enhanced by making it possible to verify the outcome of highly abstract programming process through a robot as a concrete object. In addition, the Hangul converter of robot programming language based on RCX that elementary school students can use easily was designed and developed. Furthermore, the developed tool was used for six months by students in after-school computer class and therefore learners showed a positive response.

학습자가 어려움을 느끼게 되는 프로그래밍 수업의 특징 중의 하나는 단계별 학습으로 이전 단계를 이해하지 못하면 그 다음 단계로 넘어가는데 어려움이 크다는 점이다. 이러한 어려움을 극복하고 학습 효과를 높이기 위해서는 단계별 학습을 유도하는 적절한 학습 방법이 필요하다. 본 연구에서는 성찰일지를 프로그래밍 수업에 적용한 후 설문조사를 실시하여 성찰일지가 프로그래밍 수업의 단계별 학습 효과 및 만족도를 높이고, 특히, 수업시간에는 기본적인 내용을 이해하고 있으나 복습이 부족한 학습태도를 가진 학습자들에게 보다 긍정적인 효과가 있었음을 조사 분석하였다.

Computer programming education can improve students' logical thinking and problem-solving ability. Therefore, it is essential tool to improve algorithmic thinking ability. We study how much Dolittle and Squeak influences improving elementary students' logical thinking ability. Thus, we divided 6th grade elementary students into two classes and then taught Dorittle and Squeak programming languages for 6 weeks, respectively. We compare and analyze each logical thinking ability and its sub-classifications. The results showed that Dorritle affects significant improvement, but not Squeak.

프로그래밍 언어 수업은 단계별 학습 특성으로 인해 이전 단계를 이해하지 못하면 그 다음 단계로 넘어가는데 어려움이 많아, 학습 공백기를 갖는 복학생들에게는 복학 후 수업 적응에 보다 큰 어려움이 있다. 이러한 어려움을 극복하고 수업 적응 효과를 높이기 위해서는 수업 시작 전 이전 수업 내용 및 운영 방법 등을 알 수 있는 적절한 기회와 방법이 필요하다. 본 연구에서는 사전교육 프로그램을 프로그래밍 수업에 적용한 후 설문조사를 실시하여 사전교육 프로그램이 복학생들의 프로그래밍 언어 수업에 대한 적응 효과 및 만족도를 높이는 긍정적인 효과가 있었음을 조사 분석하였다.

2015 개정 교육과정에서는 컴퓨팅 사고력을 핵심 역량 중 하나로 설정하였으며 역량 함양을 위해 문제해결과 프로그래밍, 컴퓨팅 시스템영역에서 각각 프로그래밍 교육과 피지컬 컴퓨팅을 편성하였다. 또한 선행연구를 통해 효과성을 알 수 있었지만 연구의 편차로 인해 피지컬 컴퓨팅이 가지는 교육적 효과크기에 대한 검증의 필요성이 제기되나 관련연구가 진행되지 않았다. 따라서 본 연구에서는 피지컬 컴퓨팅의 동향 및 효과 분석 연구의 부분으로 피지컬 컴퓨팅 도구 및 프로그래밍 언어의 활용 동향을 분석하고자 한다.

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.

Scratch-based programming has come to be known as an effective programming tool because of its graphic instruction modules, which are designed to be assembled like the famous LEGO building blocks. These building block-like structures allow users to more easily program applications without using other more difficult programming languages such as C or Java, which are text-based. Therefore, it poses a good opportunity for application in educational settings, especially in primary schools. This paper presents an effective approach to developing an educational robot for use in elementary schools. Furthermore, we present the method for scratch programming based on the external modules need for the implementation of robot motion. Lastly, we design a systematic curriculum, titled "Play with a Robot," and propose guidelines to using the educational programming language Scratch.

MIT App Inventor 2, much like the other block-based programming languages such as Scratch and Alice, is a useful tool that can be utilized to improve the computational thinking skills for students. The coding and the execution of program are done mainly on the computer in Scratch programming, but in App Inventor 2 programming, the students can execute the program and get immediate feedback on the smart-phone in the middle of the programming. Therefore, we can expect better enhanced learning effect. In this study, it has been claimed that the learning of App Inventor2 can strengthen the computational thinking skills of our students by extracting four core concepts of the computational thinking and then showing how these concepts are applied through the learning of App Inventor 2.

Scratch, one of the educational programming languages, provides a media-rich programming environment and easy interface to users. It supports Korean language and is utilized usefully in programming classes in elementary and middle schools. However, programming causes cognitive loads to young students. Because the programming process is a complex problem solving procedure that requires logical and abstract thinking abilities. Therefore, we developed a problem based scratch programming teaching and learning model to enhance intrinsic motivation of learners and to maximize the effects of using the scratch, educational programming language. The developed problem based teaching and learning model considered elementary students' characteristics. It was implemented in fifth grade elementary school classes and the educational effects of the model was analysed. The developed model was helpful in enhancing students' problem solving potential and logical thinking abilities.
