창의성이 강조되는 시대에 영재 교육의 중요성은 점차 높아지고 있다. 그러나 정보 영재를 위한 연구는 수학이나 과학 영재에 비해 미미한 수준이며, 특히 초등 정보영재를 위한 프로그래밍 교육은 창의적 알고리즘을 개발하는 능력을 기르는 것보다 학습자의 수준에 맞지 않는 특정 프로그래밍 언어의 사용법이나 문법 위주의 교육에 치중하고 있다는 우려의 목소리가 높았다. 이에 본 논문에서는 초등 정보영재의 알고리즘적 사고력을 향상시키기 위한 실생활 중심의 컨텐츠를 제안하고자 한다. 초등학생의 생활과 밀접하게 연관된 주제를 선정하여 학습 동기를 유발하고, Polya의 문제해결모형을 토대로 스스로 이야기를 만들고 그 안에서 알고리즘을 찾아가는 과정을 통해 알고리즘적 사고력을 향상시킬 수 있도록 컨텐츠를 설계하였다.

앞으로 우리의 삶에서 로봇은 빼 놓을 수 없는 존재이기에 미래를 지향하는 우리의 교육은 이에 걸 맞는 교육을 설계하고 시행해야 하지만 로봇을 구입해야 하는 재정적 여건으로 실시되지 못 하는 학교가 많다. 그래서 본 논문은 로봇교육 내용 중 높은 사고력과 문제 해결력을 요구하는 미로탐색 알고리즘 내용을 분석하여 초등학생의 수준에 맞는 교육내용을 설계하고자 한다.

In correspondence to the educational demand on study of computer principles that is recently being focused, this study promotes basic understanding on data structure and algorithm at the elementary student level through the process of simple numerical expressions and proposes effective education contents and methods. For this, an unplugged type computer education material was produced to understand the method of the computers for receiving data through activities. Also, we proposed students to create animation data to learn numerical expressions and algorithm through arrangements and linked lists. To examine educational effectiveness of this study, an experiment study was conducted through the education content and method to the subject of one class in the fifth-grade of elementary school located in OO metropolitan city. As a result, the student learned that there is a difference in calculation method between computers and people; and this enabled basic understanding on algorithm and data structure and presented positive responses to algorithm and data structure. In conclusion, it is confirmed that it is possible to provide effective education for students if the principle study of algorithm is proposed to proper levels.

Software education is required from elementary schools to prepare students for the fourth industrial revolution, which aims to improve algorithmic thinking. In general, teaching is divided into two stages: using a flowchart to design algorithms and implementing them through programming. However, converting a flowchart into code and checking the results in an educational programming tool is time consuming and requires additional programming activities. This study proposes a tangible coding tool that enables elementary students to convert algorithms designed at the unplugged activity into educational programming tool codes. This tool was developed in order for students to design algorithms at the level of assembling paper blocks and input them into a programming tool by taking a picture. Sixth graders were participated in this activity to evaluate its usability.

Software education is provided for 6th grade students. This study explored the algorithmic composition patterns of elementary school students. After investigating the algorithm for the 6th grade students, the algorithmic pattern of the learner was explored by calculating the cyclomatic complexity of MacCabe based on the structural programming technique. Students often use one or two choice structures to solve problems, which tend to be biased towards the starting and ending points of the problem. It is also passive in the use of selection structures. Algorithm composition depends on visible objects and one's own background. Therefore, in elementary school software education, it is necessary to present the task of thinking about the algorithm structure in the context of the algorithm and the students' experiences in accordance with the algorithm composition pattern.

"Problem-solving methods and procedures" sections in the 2009 revised informatics curriculum emphasized active use of algorithmic thinking to solve problems. And it is proposed to solve the various problems of real life using programming language for the implementation of the algorithm. Recently, various Educational Programming Language has been developed for elementary programming activity and many researches showed that students' cognitive burden was reduced in learning programming language with Educational Programming Languages. However implementation of the algorithm is difficult for novice programmer. For the reason, effective way is required for elementary students to connect design of the algorithm and implementation of the algorithm. Therefore, in this study propose the algorithm design worksheets that it is possible to create an algorithm to describe the content needed to implementation in programming education. And this study proved the effect of the algorithm design learning tools through experiment.

본 연구에서는 초등에서 알고리즘 교육의 방법으로 사용되는 언플러그드 활동에 순서도를 활용하는 방안을 제안한다. 소프트웨어 교육의 기본적인 방향은 컴퓨팅 사고력을 기반으로 문제를 해결하는 역량을 기르고자 하는 것[1]이지만, 현재는 교육용 프로그래밍 언어의 학습에 치우쳐 있거나 알고리즘 교육이 제대로 이루어지고 있지 않다. 언플러그드 활동에 순서도를 활용함으로써 알고리즘 영역의 교육을 강화하고 균형 잡힌 컴퓨팅 사고력 함양에 도움이 될 것이다.

Data structure and algorithm are primary courses for computer programming instruction. However, now those are not interesting courses for students because the programming instruction methodologies that used these courses are not the proper methodologies for the visual and windows programming. The Sorting programming is the same as other data structures. Therefore, we developed the VTSPI (Visualization Tool for Sorting Programming Instruction) which is a software component to instruct sorting program effectively for solving these problems. As a result, students can code, understand and debug their programs because VTPSI is software components based on visual programming.

In order to analyze the change of student's logical thinking, in this study, we were develop the educational materials. This educational materials were used in algorithm class through educational programming language Scratch. Algorithms of education materials were selected by analysis of foreign ACM and domestic middle school curriculum. The developed educational materials were applied to 4th grade students of elementary school. In order to analyze the change of student's logical thinking, we were used GALT short version. Total logic and Combinational reasoning, in the experimental group students, were growing significantly.

The purpose of this study is to verify learning components to be taught in each grade of middle schools, to propose hierarchical structures on algorithm content, and to resolve overlapping across related subjects. In order to verify learning components, four criteria were proposed. To evaluate practical application, they were implemented into The Proposal of Curriculum Revision on Computer Education in Middle School on MPE website. It was found that there was content overlapping between 'problem solving methods and procedures' in the middle school Informatics Curriculum and 'regulation and problem solving' in the Elementary Mathematics Curriculum. So it is needed to find a way to differentiate the contents of 'problem solving methods and procedures' from the other related subjects.
