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 objective of this research is to explore a method to utilize a programmable robot, as a potential learning tool in the elementary school's curricula. Due to their programmability and operational ease of use, programmable robots are among digital toys that today offer specially instructive features. In this research, we developed the robot game-based project contents as a tool for teaching the elementary school children to learn the algorithm, the essential part of computer programming. The LEGO material, selected as the construction kit for robot, consists of a mechanical assembly system, a set of sensors and actuators, a central control unit, a programming environment. The project requires the children to complete 3 separate tasks, each of which is developed based on the principles of algorithm. The classroom feedback supports that the robotic experiences provided the children with fun and absorption. It is likely that implementing learning with robot in regular classroom in elementary school can bring new possibilities to the educational system, provided that a thorough preparation backs up the plan.

In this paper, we have selected traveling algorithms of Line-Tracer as the focused learning elements with the PBL-based programming instruction method. Line-Tracer traveling algorithm programming has been simulated using the Scratch EPL. Development of robot web courseware such as Line-Tracer can create an effective educational environment and also provide solutions for lack of environmental conditions, such as time or spatial factor restrictions and excessive expense issues; these are major obstacles to developing robot programming education. Finally, we analyzed the effects on growth of student's logical thinking and problem solving abilities by demonstrating the Scratch application courseware to the field of elementary education.

This paper is to design smart based collaborative learning model for programming education of fifth graders of elementary school and applies it to a class and analyze its result. Designed learning model is composed of understanding of concept, realization, learning and sharing and it includes step by step learning materials and smart based collaborative learning activities. Scratch traffic light learning materials at leaning stage classify content to be checked in programming by colors and write to support programming internalization of learners. Provision of smart based collaborative learning activities that considered learning conditions of learners makes it possible for beginners to participate in and keep study actively. This study showed that there was statistically significant difference in learners' programming interest and those who achieved over 8 out of 10 points were 60.7% at three stage evaluations for achievement level that applied learning model which suggests that satisfactory achievement level is achieved.

Tangible programming tool based on a graphic interface platform is unlike programming on a computer due to the fact that young students can utilize their hands and tools without an on-line interface. This is effective in enhancing student understanding about difficult programming algorithms. B-Bricks was constructed to consolidate multiple commands onto one block, having immediate feedback about the result, and other algorithms based on assessing the problems that arose from the previous tangible block model. Upon experimenting on 29 students of grades 4th~6th, it was observed that as problems became more difficult, the accuracy of the answers derived diminished and their problem-solving time increased.

In this paper, we introduce a new programming learning system for young students. The programming learning system consists of a LED display kit and a web-based flowchart system. The LED display kit acts as an output device by way of displaying lights while following a set of instructions given through a flowchart programming. In the flowchart system, the students use symbolic variables for the calculation and can get various displays or animations after creating a flowchart by drag-and-drop. Then we describe the survey results of various programming classes using our system between fall 2005 and spring 2009. The programming teaching was conducted with diverse groups such as elementary school students, gifted students, college students, and teachers etc. The responses from our in class surveys were generally positive.

It is possible to increase integrated thinking and problem solving ability ultimately through STEAM education. This study developed STEAM model to apply to subjects and scratch knowledge education that sixth grade students in elementary schools can learn each subject through STEAM learning by applying scratch programming and it was applied and analyzed during regular classes and afterschool classes for sixth grade students. As a result, it was possible that about 70% of sixth grade students, the subject of model application were able to do STEAM learning initiatively by applying scratch program. Other 30% of the students were able to do STEAM learning partially through scratch. As for the achievement assessment of STEAM learning, it was evaluated that most of the students for the evaluation subjects got satisfactory achievement level by getting overall average 7.83 out of ten. Thus, it is considered that STEAM learning model by applying scratch is very superior that applying existing programming language such as C, BASIC etc.

The purpose of this study was to investigate whether block-based programming language, which is currently being used in elementary and secondary schools, attracts students' interest and motivates them to learn. In addition, this study was to investigate how block-based programming language can help students improve their computing thinking ability and have a good effect on learning text-based programming to learn in high school. In addition, this study tried to study the direction of education linked with artificial intelligence and programming, which are popular in the era of the Fourth Industrial Revolution. The interest in software education has increased so much that software and information education from elementary school to high school has achieved quantitative and qualitative growth that can not be compared with before. However, in the field of artificial intelligence, discussions have begun, but we can not say that we have yet established ourselves in our education. We will discuss how block-based programming and text-based programming will be combined with artificial intelligence and educated.

Elementary school students should have many opportunities to find their abilities and talents. However, informatics education in Korea does not target the entire elementary school students, opportunities for informatics education are given only to some students. Unlike possibilities to find mathematics gifted students and science gifted students, opportunities to find informatics gifted students are very limited. This study aims to solve current problems through a robot education program based on SEM(Schoolwide Enrichment Model). Using modified curriculum and school enrichment cluster, robot programming education is implemented at the pilot school. The result shows that robot education program based on SEM improved creative potentials of elementary school students.

In this research, we investigated the effect of robot programming education on adaption for school life of student with learning disabilities focusing on learned helplessness and the quantity of spontaneous communication. The participant of this study was the student supported with LD really in 4th grade elementary school. Results of the study present that learned helplessness was declined, the quantity of spontaneous communication was increased throughout robot programming education. Based on results, these finding suggested ways to practice the application of strengths-based instruction, intervention utilizing gamification for school life of student with learning disabilities in educational setting.
