The purpose of the present study was to evaluate some variables, such as learner's cognitive characteristics and a training-program emphasized proportional logic, in proportional reasoning development. Seven hundred and ninety students in junior high schools were enrolled as subjects for the study which investigated learner's cognitive characteristics in proportional reasoning development and asked to perform tests of logical thinking, card sorting, planning, mental capacity, cognitive style, brain lateralization, information processing pattern and scientific reasoning. In addition, one hundred and thirty-three students who failed to solve proportional thinking items were administered a training program which has been applied to improve the subjects' proportional reasoning skills. The results showed a significant higher correlation between subjects' performance score on proportional thinking test, and their age and scores on scientific reasoning test, mental capacity, information processing test and perseveration errors on card sorting test. Also, the training program applied in this study showed an effective result in developing subjects' proportional reasoning skills. Further, this study may serve as a suggestion in the efforts to investigate factors of proportional thinking development and a contribution for the future research in other logical thinking development.

This study aims to investigate the characteristics, concepts, types, and strategies of unplugged coding for young children based on computing thinking. The key to unplugged coding for young children is computing thinking. Unplugged coding based on computing thinking for young children can be used to solve problems that can be encountered in everyday life through playing games based on logical thinking by positively utilizing algorithm boards, s-blocks, coding robots, and smart devices without using programs And find new ways to play. Types of unplugged coding for young children include direct input to smart devices, using coding robots with dedicated apps, practicing coding procedures using algorithms, and using hybrid methods. Strategies include understanding algorithms, drawing flowcharts, dividing into smaller parts, finding patterns, inserting, and predicting outcomes.

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 current information and knowledge-based society, a nation's economy power heavily depends on IT-related industry and technology. In this sense, most countries are trying to foster IT industry by developing new and innovative IT technologies. Traditionally, only a few talented persons have been leading the whole IT industry. Thus, it is very important and necessary to identify and support the gifted children in IT in early ages for development of IT industry. The purpose of this paper is to investigate study performance of the gifted children in IT for different grades. Our research is focused on especially 4th grade students, 5th grade students, and 6th grade students in elementary schools. Among various abilities of the gifted children in IT, in this paper, we are interested in programming ability and logical thinking ability. To our best knowledge, there is no research work on study performance depending on different grades of the gifted children in IT. For this purpose, the gifted students in gifted science education center attached in a university at Seoul Metropolitan Area are selected and their test scores for 8 years were collected and analyzed. The statistical analysis results show that there is no significant difference among 4th grade students, 5th grade students, and 6th grade students for programming ability and logical thinking ability. We hope that this result can help suggest and propose study contents, curriculum, principles and laws for the gifted education in IT.

프로그래밍 학습은 프로그램의 작성, 오류 수정, 실행을 통해 학습자의 문제 해결력과 논리적 사고력을 향상시킨다. 따라서 프로그래밍 언어는 쉽고 익히기 쉬어야 한다. 또한, 초등학생은 Piaget의 인지적 발달 단계로 볼 때 구체적 조작기(concrete operational period: 6, 7$\sim$11, 12세)에 해당하는 시기이다. 이 시기는 구체적인 사물을 가지고 조작함으로써 논리적 사고가 가능하다. 따라서 본 논문에서는 프로그래밍이라는 매우 추상적인 작업을 로봇이라는 구체물을 통해 결과를 확인할 수 있게 하였으며, 프로그래밍 학습의 초기 단계에 있는 초등학생이 쉽게 사용할 수 있도록 한글을 기반으로 프로그래밍 학습을 할 수 있도록 하고, DB를 활용하여 명령어를 사용자가 추가, 삭제, 수정할 수 있는 한글 기반의 로봇 프로그래밍 도구를 설계 및 개발하였다.

This study aimed to develop an HTE (It is an abbreviation for Here, There, and Everywhere) STEAM program combining with the use of an analogy in a middle school subject unit 'the solar system' and realize creative education for intelligent information society through a process of verifying the effectiveness of the program. For reference, the program was applied to 354 students in the first grade of two middle schools in South Korea - one was A middle school in Sejong City, the other B middle school in Pyeongtaek City. The STEAM program was revised and made up for the weak points for three times by a group of experts, and then it got verified for validity. The final version of the program was applied to middle school education sites in Korea for six periods in total. In other to confirm the effectiveness, two types of tests - logical thinking ability test and STEAM attitude test - were conducted before and after the program treatment. On top of that, the STEAM satisfaction test was also implemented in order to explore the students' recognition of the program after the program treatment. The results of this study were as follows. First, it turned out the STEAM program using the analogy was effective in improving the students' logical thinking ability. Second, the STEAM program blended with the analogy was also effective in improving the students' STEAM attitude. Third, the students' recognition of the STEAM program using the analogy was quite positive, and the program was efficacious in intriguing the students' interests in science. Judging from the results of the program, the students' satisfaction with the classes they take will be expected to be higher if the STEAM program is implemented in the next-term classes with more sufficient time.

최근의 컴퓨터 교육은 컴퓨터의 개념과 원리의 이해보다는 단순히 응용프로그램의 사용법을 익히는 등 컴퓨터 활용 교육에만 치중하고 있다. 그러나 21세기 정보화를 이끌 인재양성을 위해서는 문제해결력과 논리적인 사고력을 기르는 컴퓨터 교육이 필수적이다. 이에 본 연구는 컴퓨터과학원리 중 검색 알고리즘에 대한 교수 학습방법을 설계해 초등학생을 대상으로 하여 학습이 가능한지 알아보고자 한다.
