Software education will be implemented in elementary, middle and high schools from the 2018 school year. One of the core contents of software education is algorithm education. As with other subjects, algorithmic education can also be seen as the success of students' initiative. And students' initiative learning can lead to increasing students' interest and commitment. In this paper, I propose the concept of software battle by applying sports games to algorithm education. The software battle defined that the programmed objects play to solve a given problem without human intervention in the virtual world. This can be applied to various topics. In this paper, I tried to apply it to sorting numbers which is a representative subject of algorithm education. The results of applying the algorithm education to the software battles showed a positive response, although the students felt the unfamiliar side. This indicates that the software battle can be used as one of the various education methods.

Computer programming in computer education draws much attention recently. Encouraged by the increased tendency of acquiring logical ability and creativity through learning, various attempts have been made to develop them through learning computer programming in the area of computer education as well. The fact that a computer program is the representation of a computer algorithm expressed in a computer language makes us realize that the devise of a logical method for a solution - i.e., the design of an algorithm - is the key to the solution of a problem. Recognizing the importance of computer algorithm would lead us to such a point that systematic investigations for directional establishment for algorithm education are necessary. We observe that researches on teaching computer algorithm have concentrated mostly on specific problems such as sorting and searching, which can be characterized as problem-dependent and individual. In this paper, the idea of conceptual algorithm is stated from the standpoint of conceptual types of problem-solving methods which are considered as problem-independent and collective. A novice approach to algorithm education based on the characteristics of types of conceptual algorithms is proposed for the purpose of developing systematic, problem-independent, algorithmic problem-solving capabilities of learners, which is widely different from the current methods of individual and problem-dependent algorithm education.

Early algorithm education is very important in order to nurture excellent S/W developers in an information society. However a algorithm learning is a great challenge to elementary school students since understanding what a computer algorithm written in a static text format meant to do is difficult. It is expected that a student can easily visualize a algorithm through animations. In this study, we evaluate the pedagogical effectiveness of algorithm visualizations in teaching the fundamental data structures and algorithms in elementary schools. Thus we defined a new measure called 'Algorithm Visualization Factor(AVF)' and developed both text-oriented and animation-oriented PPTs of algorithm education elements, that is, Stack, Queue, Bubble Sort, Heap Sort, BDF, and DFS. We have conducted experiments and evaluations on diverse students groups. Extensive experiment results show that the average score of the student groups using animation-orirented PPT is greater(22%) than the one of the student groups using text-orirented PPT.

The content of software education for elementary school students in the 2015 revisions to the national curriculum are not sufficient because class time dedicated to software education has been limited to 17 hours in fifth and sixth grades. In this study, I developed the algorithm and programming model for Korea. I analyzed domestic and international software education curricula as well as training platforms, such as Code.org, Blockly Games, and Entry. The suggested algorithm and programming framework is known as the Rainbow system, which is divided into 7 steps, 14 criteria, and 3 content areas--understanding the algorithm, the actual programming, and evaluation of the program. Using the Rainbow system, once students have completed a level they can be promoted to the next stage, regardless of their grade.

Currently computer education has been emphasized improving thinking skill instead of practical education of applied software. There are various studies that are to teach algorithm with visualization learning materials or activitives-centered unplugged class. However, algorithm classes for elementary school have various difficulties. One of the reasons is insufficient learning materials and teaching methods. Therefore we designed a activities-centered algorithm class for elementary school students. We hope this study will contribute to the study of algorithm classes for improving kids' thinking skill.

Algorithm education is emphasized as an instrument for teaching the basic principles of Computer Science. But these materials is very short-fall. We'll present the CS Unplugged-based algorithm contents, which is easy to learn for elementary student. These contents for self-directed learning consisted of the activity-based learning. For problem-solving algorithm learning in everyday life we were developed the hashing techniques on the basis of the basic searching and sorting algorithms. For checking the adequacy of these materials were tested by surveys of teacher professional groups, and we obtain the appropriate conclusions for sorting algorithm contents for improving the problem-solving ability for in elementary student.

The importance of algorithm education has been emphasized for creative problem-solving capability. Especially, algorithm teaching materials related with mathematics and science are under development to enhance logical thinking. However, there are not enough teaching-learning models applicable in the field of education. Therefore, this paper proposed a teaching-learning model for effective algorithm education. The teaching-learning model reflects two characteristics : an algorithm learning process is spiral, and algorithm education is based on logical thinking. Furthermore, a survey was conducted for students' satisfaction, and the result was a mixed teaching-learning model with PBL, SDL, and peer tutoring. Based on the proposed model, examples of classes for mathematics and science are suggested to show the feasibility of effective algorithm education.

개정된 7차 교육과정의 정보 교과에서는 창의적이며 논리적 사고력을 바탕으로 한 문제해결 능력 함양에 중점을 두어 중등학교에 공통적으로 '문제해결방법과 절차'라는 대영역이 포함되었다. 이 단원의 내용 요소 중에 알고리즘에 대한 내용이 포함되어 있다. 알고리즘에 관련된 내용요소를 교육할 때 기존 연구가 부족하여 교사와 학생들이 활용할 자료와 소프트웨어가 충분하지 못한 실정이다. 본 연구에서는 개정된 중등학교 정보 교과의 알고리즘에 대한 내용을 분석하고, 이 알고리즘 교육에서 공개소프트웨어를 활용하는 방안을 제시한다.

현재 학교의 컴퓨터 교육이 소프트웨어 활용 측면에서 벗어나 컴퓨터과학 교육을 강화하는 쪽으로 방향을 전환하고 있다. 특히 2005년에 개정된 정보통신기술 운영지침에 따르면 초등학교에서부터 알고리즘을 학습 내용으로 다루도록 하였으며 이에 따라 초등학교 현장에서도 알고리즘을 쉽고 효과적으로 지도하기 위한 다양한 교육 방법 연구가 필요해졌다. 현재까지 초등학생 대상의 컴퓨터과학 교육 연구는 대부분 초등학교 고학년을 대상으로 구체적인 조작과 활동 중심으로 제한되었다. 이에 본 연구에서는 정렬 수행 과정이 시뮬레이션되도록 제작한 애니메이션 컨텐츠를 통해 여러 알고리즘의 방법을 경험하도록 하는 ICT 기반의 알고리즘 교수-학습 과정을 설계하여 저학년에 적용하고 성취도와 학생들의 반응을 분석하였다.

초등 교육 과정에서 컴퓨터 교육은 재량시간으로 컴퓨터의 개념과 원리의 이해보다는 도구로서의 기술 교육에 할애하고 있다 그러나, 초등학생들은 이미 생활에서 쉽게 접할 수 있는 정보화 시스템에 익숙하여 컴퓨터를 이용하여 다루는 기술은 교과의 수준을 상당히 갖추고 있다. 또한, 게임서버. 윈도우즈, 운영체제, 동영상/음악 파일 등의 다운로드/업로드 등의 단어에 이미 익숙해 있다. 이러한 용어들의 이해는 컴퓨터의 원리인 운영체제, 네트워크, 알고리즘, 프로그램 등에 대한 개념 교육으로 해결할 수 있다 따라서, 본 연구에서는 컴퓨터의 가장 중요한 원리인 알고리즘 중 정렬 알고리즘을 사례를 이용하여 역할놀이 모형으로 6학년 초등학생을 대상으로 학습을 수행하였다. 학습한 결과 정렬 알고리즘을 쉽게 유도해 냈으며. 질적인 분석으로 컴퓨터의 원리 교육에 대한 학습 효과가 있음을 보이고자 한다.
