The latest programming paradigm has been mostly geared toward object-oriented programming and visual programming based on the object-oriented programming. However, object-oriented programming has a more difficult and complicated concept compared with that of existing structural programming technique; thus it has been very difficult to educate students in the IT-related department. This study designed and implemented a Java robot training kit in which the Java virtual machine is built so that it may enhance the desire and motivation of students for learning the object-oriented programming using the training kit which is possible to attach various input and output devices and to control a robot. The developed Java robot training kit is able to communicate with a computer through the USB interface, and it also enables learners to manufacture a robot for education and to practice applied programming because there is a general purpose input and output port inside the kit, through which diverse input and output devices, DC motor, and servo motor can be operated. Accordingly, facing the IT fusion era, the wall between the academic circles and the major becomes lower and the need for introducing education about creative engineering object-oriented programming language is emerging. At this point, the Java robot training kit developed in this study is expected to make a great commitment in this regard.

The concept for algorithm needs to be established in various fields such as architecture, medicine and life science but understanding only theoretically has its limits. It is therefore educated using many multimedia factors but still is difficult to bring interests and carry out the higher level courses. For algorithm and programming, due to the subject's peculiarity it is very important to actually execute the program to understand the realization theory. In this paper, it aims to design a basic concept of algorithm using a flow chart of visualizing program and an algorithm education system to learn the basic programming C language, which is the fundamental element in algorithm learning.

Given the recent pace of development and expansion of Artificial Intelligence (AI) technology, the influence and ripple effects of AI technology on the whole of our lives will be very large and spread rapidly. The National Artificial Intelligence R&D Strategy, published in 2019, emphasizes the importance of artificial intelligence education for K-12 students. It also mentions STEM education, AI convergence curriculum, and budget for supporting the development of teaching materials and tools. However, it is necessary to create a new type of curriculum at a time when artificial intelligence curriculum has never existed before. With many attempts and discussions going very fast in all countries on almost the same starting line. Also, there is no suitable professor for K-12 students, and it is difficult to make K-12 students understand the concept of AI. In particular, it is difficult to teach elementary school students through professional programming in AI education. It is also difficult to learn tools that can teach AI concepts. In this paper, we propose an educational model for elementary school students to improve their understanding of AI through play or experience. This an experiential education model that combineds exploratory learning and discovery learning using multi-intelligence and the PLAY teaching-learning model to undertand the importance of data training or data required for AI education. This educational model is designed to learn how a computer that knows only binary numbers through UA recognizes images. Through code.org, students were trained to learn AI robots and configured to understand data bias like play. In addition, by learning images directly on a computer through TeachableMachine, a tool capable of supervised learning, to understand the concept of dataset, learning process, and accuracy, and proposed the process of AI inference.

Because the success of SW education depends on teachers' competences and understanding, many universities of education are carrying out SW education for pre-service teachers. The purpose of this research is to analyze the current status of pre-service teachers' programming learning experiences and understanding of curriculum and educational effects related to SW education. The participants were 294 junior and senior students enrolled in a university of education. In relation to 'programming learning experiences', many responded positively in terms of interest, usefulness and willingness to learn. However, many were not satisfied with their programming experiences, felt difficulty in programming, and evaluated their programming abilities as low. For the 'understanding of SW education curriculum', many recognized the necessity of SW education and understood that the allocated time was insufficient. Both positive and negative opinions were reported concerning the fact that SW education is conducted in practical arts. In comparison, many did not understand well about the concept and characteristics of SW education and the details of the curriculum. In relation to the 'understanding of SW education effects', many understood positively about all the effects presented in the questionnaire including problem solving abilities and creativity. In addition, significant differences were found among pre-service teachers' major categories regarding the programming learning experiences and the understanding of SW education curriculum and effects. Based on the results of the research, suggestions were made for the improvement of the pre-service teachers' SW education program.

As a 21C core skill, computational thinking has been focused recently, and computer programming education is popular in primary and secondary schools. This paper aims to analyze the computer programming learning results based on gender difference and verify the reasons causing the difference. In this research, we focused on students' abstract thinking level as a variable and used C programming language and the RUR-PLE. Also, in this research, we focused on the concept of abstraction, one of the main component of computational thinking. And then, we analyze 587 high school students' abstract thinking level and survey them in order to find a new method for enhancing programming skill. In addition, we analyzed the causes for the difference in how the abstract thinking level applies when the students understand various structures of computer programs. From the results, we can propose a computer programming education method that enhances students' merits and compensates their drawbacks in the near future.

Since 2019, the informatics education is being conducted for elementary school 5th, 6th grade students through the curriculum revised 2015. But, informatics education is implemented from the lower grades of elementary school in many countries. The purpose of this study was to suggest the direction in the choice of programming language considering characteristics for lower grades student. In order to achieve the goal, evaluation criteria were developed considering the development characteristics of lower grades and necessary elements of educational programming language. The results of analyzing the usability of the two languages based on the criterion are as follows. First, Viscuit can be used to consider the expressive power of students with lower school age or to learn algorithms without learning about programming concepts. Second, ScratchJr is easy to learn the concept of algorithm and programming. This study is meaningful in that has presented implications considering the developmental state of the students in preparation for rhe programming education.

Analyzing adaptive possibilities of agents in multi-agents system, we have discovered new aspects of ambient intelligence in distributed modular systems using intelligent building blocks (I-BLOCKS) [1]. This paper describes early scientific researches related to technical design, applicable experiments and evaluation of adaptive processing and information interaction among I-BLOCKS allowing users to easily develop ambient intelligence applications. The processing technology presented in this paper is embedded inside each DUPLO1 brick by microprocessor as well as selected sensors and actuators in addition. Behaviors of an I-BLOCKS modular structure are defined by the internal processing functionality of each I-Blocks in such structure and communication capacities between I-BLOCKS. Users of the I-BLOCKS system can do 'programming by building' and thereby create specific functionalities of a modular structure of intelligent artefacts without the need to learn and use traditional programming language. From investigating different effects of modem artificial intelligence, I-BLOCKS we have developed might possibly contain potential possibilities for developing applications in ambient intelligence (AmI) environments. To illustrate these possibilities, the paper presents a range of different experimental scenarios in which I-BLOCKS have been used to set-up reconfigurable modular systems. The paper also reports briefly about earlier experiments of I-BLOCKS in different research fields, allowing users to construct AmI applications by a just defined concept of modular artefacts [3].
