In the newly revised curriculum, it is aimed to raise student who has creativity and convergence ability with computational thinking. Based on the analysis of revised curriculum including software education in elementary school, this study proposed educational program that can be applied in actual school field, considering various factors. This educational program using Bitbrick was conducted by 50 students in fifth grade that consist of 23 students in Seoul and 27 students in Gyeonggido during five weeks in 17 periods. The purpose of this study is to verify the effect of application of software education program in terms of computational thinking ability and problem solving ability. The effect was verified after comparing the result of pre-test and post-test through T-test. So, this study obtained improvement of computational thinking and problem solving ability.

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.

The software education to elementary students will be conducted from 2019. One of highlights of software education is a programming experience. It requires a higher level of programming education to students that are interested in programming. This problem can be solved by the club activities. But the materials for programming education for elementary students is not much. Therefore, we developed a programming material for club activities of the elementary school. We did not develop it as a programming manual. The students can understand a problem, can design through decomposition and abstraction processes, and can write a program when they are learning with this material. As a result, we expect that they can enhance their computational thinking abilities. We proved that our material is suitable for elementary students through a demonstration class. Therefore, we expect that our development methodologies for the material for programming education will contribute to develop a material for programming education.

In the existing curriculum of the Elementary Computer Education, it is hard to improve the CPS(Creative Problem Solving) skill and logical thought since the 7th national curriculum emphasizes application programs and CAI softwares. To complement this drawback, it is required to teach the principal of the computer science but there is not many researches for what problems of teaching computer science exist and what the response of students are. Thus, we carried out a research to know whether the students of elementary school can understand principal of computer science in the field of subject matter education. We found that the students can learn the principle of Saving Bitmap Image if the class level is adjusted properly.

This purpose of this study is to develop and apply the physical computing lessons based on the software guidelines from the Ministry of Education (2015). In this study, I research how computational thinking occurs in class by applying the physical computing lessons to elementary students based on computational practices. The physical computing lessons and analytic methods for computational thinking in this study can be used as a sample and case-study to develop the lessons in the educational field.

In this study, we tried to find out the level of inductive reasoning ability and the aspects of visualization components shown in students in the class using exploratory software for the 'congruence and symmetry' unit in the second semester of the 5th grade of elementary school. To this end, classes using GeoGebra, one of the exploratory software, were conducted for a total of 19 students in one class of fifth graders in elementary school, and the results of the students' activities were analyzed. As a result of this study, the level of inductive reasoning ability of students remained at a similar level or developed, and it was shown that students inferred new properties of shapes using various functions of software inductively. In addition, in terms of visualization, students were able to quickly and easily draw shapes that met the conditions, and unlike the paper-and-pencil environment, using the 'measurement' and 'symmetry' functions, they transformed and manipulated complex yet precisely congruent and symmetrical external representations. Based on these analysis results, implications for the use of exploratory software in the area of figures were derived.

본 프로젝트는 ChatGPT와 카카오톡 채널 챗봇을 사용하여 초등학생 대상의 학교폭력 예방교육을 위한 대화형 챗봇을 개발한다. 이를 위해, 한림대학교 간호대학에서 제공받은 학교폭력 예방교육 자료를 기반으로 ChatGPT를 사용하여 데이터를 증강하였고, AWS RDS의 데이터베이스에 사용자의 예상 발화와 그에 대한 답변을 저장하였다. 그리고 AWS Lambda에 REST API를 구현하고, AWS API Gateway를 통해 카카오톡 채널 챗봇과 연결하였다. 사용자가 발화를 입력하면 발화를 포함한 요청이 AWS Lambda로 전달되고, ChatGPT를 사용해 답변을 생성하며 데이터베이스에 저장된 데이터와 코사인 유사도를 비교한다. 이때 기준치보다 유사도가 높다면 저장되어 있던 데이터를 반환하고, 낮다면 생성된 답변을 반환한다. 이후 반환된 답변을 카카오톡 채널 챗봇으로 전달해 사용자에게 출력한다.

In the knowledge and information society, computer education for elementary school is very important. When students are young, they use digital devices. In these days, computer education is software education has attracted only focused on software education curriculum and courses are being made. A software education must be included the education of a computer system. In this study, at least what the computer was designed and built from the elementary curriculum about whether that is how the computer operates. Not made from first grade to sixth grade to grade-level system it made the students of level 7 step system. This is a flexible strategy for education in the school or grade level requirements. This study is meant to argue that the need to be a computer system from elementary education.

This study derived optimized teaching aids that use the physical computing method as the solution for effective software education at the elementary level. We set standard for selecting physical computing teaching aids in elementary-level by gathering the opinions from previous studies and think tanks and then applied the standard to some aids and choose one. We also made lesson plan and tried it to the experimental group. Subsequently, students' logical thinking skills showed a statistically significant improvement in terms of the t-test. Also, in the analysis of the effect size, it was shown to have a positive influence on the improvement of the students' logical thinking skills. Additionally, survey of satisfaction evaluation from the students showed that the teaching aid selection standard was effective in selecting suitable teaching aids for elementary students and that the classroom activities utilizing physical computing teaching aids were at a suitable level for elementary students.

In the 2015 revision curriculum, software education must be conducted for 17 hours in elementary school fifth or sixth grade. Pre_service elementary teachers should be able to teach software. In this study, learning factors according to the achievement criteria for software education will be defined for pre-service elementary teachers. Pre-service teachers were taught by learning elements. As a result, the pre_service teachers were able to create teaching and evaluation materials for each learning element. It was also found that the pre-service teachers improved their ability to teach software education in elementary school based on these materials.
