This paper is proposed to present elementary algorithmic thinking-based Squeak E-toy programming problems for flowchart-based programming educations without programming languages in elementary programming educations. Furthermore, this paper proves the validity and effects of developed Squeak E-toy programming problems through measurement analyses of metacognition and GALT logical thinking ability experiments by comparing with the language-based traditional programming education.

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.

현대 지식정보화 사회에서 학생들의 자기 주도적 학습능력을 중시하는 시대적 요구에 따라 본 연구에서는 스크래치 프로그래밍 교육을 통하여 학생들의 자기 주도적 학습능력에 가장 많은 영향을 미치는 상위인지능력을 향상시키기 위한 방안을 제시하고자 한다. 기존의 여러 교육용 프로그래밍 교육은 그 자체의 기능을 익히는데 너무 많은 시간과 노력이 소요되어 정작 프로그래밍 교육을 통해 얻고자 하는 것을 얻기에는 부족함이 많이 있었다. 하지만 최근 개발된 교육용 프로그램 스크래치는 기존에 교육용 프로그램이 갖고 있던 여러 가지 단점을 보완하고 보다 쉬운 프로그래밍 교육을 통해 논리력이나 문제해결력 같은 고인지 사고능력을 길러줄 수 있다. 자신의 인지상태를 탐색하고 학습 혹은 문제 해결 과정에 필요한 인지적 자원을 분석하며 능동적으로 조정하는 인지적 상호작용의 총합인 상위인지능력의 향상에 중점을 둔 스크래치 프로그래밍 교육을 통해 학생들의 상위인지능력을 향상시킬 수 있을 것으로 기대된다.

21세기 지식 정보 사회에서는 다양한 학문 분야의 영역을 넘나드는 융합적이고 창의적인 사고를 하는 통섭적인 인재가 필요하다. 이에 우리나라에서는 STEAM 교육을 강화하고 있는 추세이고 관련된 연구도 활발히 이루어지고 있다. 그러나 대부분 과학중심의 STEAM 교육이 이루어지고 있는 실정이다. 예술을 통해 얻는 교육적 가치를 고려해 볼 때 STEAM 교육에서 예술을 보조적 수단으로 여기는 경향은 개선되어야 한다고 생각한다. 이에 본 연구에서는 스크래치와 로봇을 활용한 예술 교과 중심의 STEAM 교육 프로그램을 설계하고자 한다.

The new national K-12 Information subject curriculum which will be effective in year 2010 includes algorithm and programming sections. Programming languages in K-12 are more effective the Educational Programming Language (EPL) than general language, because it focuses on developing problem solving ability rather than training a programmer. Therefore, it is necessary to study for suitable EPL in Korean K-12 curriculum. In this study, we studied and analyzed various types of EPLs available and strategies to apply them to the new national curriculum. First of all, we chose 26 educational programming languages and analyzed their characteristics and functions. Also, we investigated associations between key factors of the new Information curriculum and each language and suggested a proper language for their students' level. Finally, we considered possible problems and suitability to Korean K-12 students. The result of this study help us to choose what is the proper EPL and to consider applicability and criteria of EPLs.

The main aim in software education is to improve problem-solving ability based on computational thinking with the healthy information ethics. For this purpose, many institutions have attempted various educational programs such as Educational Programming Language, Physical Computing, and Robot education. However, it is possible to obscure the essence of computer education for computational thinking if the computer education focuses on using certain special education programming language and products. Therefore, this paper suggests a method of algorithm education using RAPTOR which is a visual programming development environment and is based on flowcharts. In order to verify the effectiveness of the algorithms education using the RAPTOR, 16 high-school students were applied to an educational program for twelve hours on five steps and then we obtained positive results.

Software (SW) education is guided by the government to operate not only computer subject matter but also related subject matter. SW education is highlighted in the 2015 Revised Curriculum and Guide for Operating SW Education. SW education is related with science education. For example, education on algorithms employing SW and activities using sensors/output control can be an effective strategy for scientific inquiry. The method can also be applied in developing Computational Thinking (CT) in students. In this study, we designed lessons to solve everyday scientific problems using Educational Programming Language (EPL) SW and physical computing materials and applied them to high school students. We conducted surveys that were modified from questionnaires of Internet application capability and based on the standard of accomplishment of SW education as well as elements of CT to find out the change in perceptions on programming and CT of students. We also conducted a survey on students' attitude toward science learning after an SW inquiry activity. In the results, perceptions on programming and CT of students were improved through lessons using unplugged activity, EPL SW, and physical computing. In addition, scores for interest, self-directed learning ability, and task commitment were high.

Scratch programming comes into the spotlight as Education Programming Language. Especially, it is made better use at educational class by accessibility and visuality in elementary school. But most of latest research is just focus on effective for programming education and prove effectiveness once more. In this study, possibility about curriculum using Scratch programming and specific applicable methods were suggested. This research suggested that how to study with scratch programming through lesson "Make a pattern" in 5th grade Math curriculum at elementary school. And there was reflected that we can verify programming procedure visually and improve creativity.

The purpose of this study was to develop and apply the elementary teacher training course for educational programming language based on TPACK in order to make elementary school teachers fully equipped with teaching efficacy for SW education. As a result, the informatics teaching efficacy of the teachers in the experimental group who participated in EPL training course developed based on TPACK was statistically more significant than the teachers in the control group(t=4.13, p<.001). The dependent sample t-test of the experimental group showed a statistically significant increase with t=4.57 (p< .001). It proved that TPACK-based teachers' training course is effective to improve teachers' informatics teaching efficacy. It is suggested that the development of SW education teacher training course should be systematically structured considering TPACK framework.
