The aim of this study was to develop and analyze a short course educating App Inventor and Arduino that showed the importance of software for youth. The course consists of a total of 10 missions for a 4 hour course divided into 2 parts, each 2 hours respectively. We conducted a basic course of Arduino for hardware and software, Processing for server programming, and App Inventor for programming for smartphones. The final mission was to send a signal to a server with a smartphone and to control light connected to a relay which passes Arduino connected with a server and serial communication. Participants completed 95% of missions, and we found the course had an educational effect for improving creativity and realization of software importance.

This paper investigates the three main functions of a typical visual app programming environment for Novice Programming developers, and compares the features. The Scratch is a visual programming environment for education, anyone can create a story easy as possible variously interaction, games, animations and more. App inventor provides precise and professional application development capabilities as compared with scratch. App Inventor in runs independently of the computer platform, and has a feature that must be constantly connected to the server over the internet, while the Inventor app runs. M-Bizmaker is suitable for commercial application development, consists of m-BizBuilder, m-BizEngine, m-BizServer or the like, provides a cross-platform visual programming environment.

In this paper, we implemented the pattern matching with the Arduino and App Inventor platform under the bluetooth mobile environment between Android phone and Arduino Platform. The combination between Arduino and App Inventor makes the feasibility of Android programming easy by wireless communications and provides the opportunity to broaden the functionality for mobile device. We used the softwares which were Arduino IDE, VC++, OpenCV, Processing and App Inventor. And also compared the performance of mobile Arduino platform with LabView GUI programming, we reduced the usage of libraries that compiled and executed the pattern matching programming. We experimented the mobile embedded platform performance under bluetooth communication and verified the functionality of the mobile Arduino platform design for identifying the pattern matching.

Open source software allows revising and adding a new idea on them as well as debugging themselves. The open source software can be utilized as various educational programs as well as development of a commercial software products using them. MIT App Inventor, one of the block-based visual programming environments for education, supports building a local server and even revision of the platform itself by providing its own source codes. In this paper we implement App Inventor open sources on the local server. Especially we present how to revise and implement a new App Inventor platform reflecting their own requirements in schools or educational institutes and how to build a local server operating the revised App Inventor platform. They can provide more interactive educational environments to students and improve educational satisfaction through the active customizing of the platform itself such as adding new programming block components requested by students.

In this study, we presented a App Inventor utilization Software Education program in the process of education for Computational Thinking improvement of elementary school girls. In order to analyze the effects of education programs that have been developed, to elect the 3, 4, 5 grade girls of the sample of volunteers by volunteers form collection as an experimental population, was charged with the development programs, and It was analyzed educational effect using the results of the pre-post tests. The results of the analysis, App Inventor utilization Software Education program that was developed in this study it was found that help in Computational Thinking kidney of elementary school girls.

Recently, the emphasis on education of informatics gifted elementary students is to make creative leader in knowledge-based society. It need the high mental faculties and problem solving ability to solve many problem situations for students. In this paper, we developed App Inventor programming education plan. We taught this plan to gifted elementary students and observed the effects of their problem solving ability, self-efficacy and achievement of programing process. In order to achieve the research goals, we designed the appropriate App Inventor programming plan for gifted elementary students and we changed the Learning Model of Renzulli's three step for gifted students to achieve this research goals. Designed learning program was utilized by twenty informatics gifted elementary students for 15 times during five weeks period. In conclusion, we confirmed that App Inventor programming education for gifted elementary students affected the problem solving ability, self-efficacy and achievement of programing process positively.

As the fourth industrial revolution becomes more popular and advanced services such as artificial intelligence and Internet of Things technology are widely commercialized, awareness of the importance of software is spreading. Recently, software education has been taught not only in elementary school and college but also in college. Also, there is a growing interest in computational thinking needed to solve problems through computing methodology and model. The purpose of this study is to design an app inventor course for non-majors software education based on computational thinking. As a result of the study, six detailed competencies of computational thinking were derived, and six detailed competencies were mapped to the app inventor learning elements. In addition, based on the computational thinking modeling, I designed an app inventor class for students who participated in IT curriculum of university liberal arts curriculum.

Recently, there are efforts to improve my learning ability by using various learning tools based on ICT technology. The application such as games is used in conjunction with lecture class to induce interest in the class and to enhance the learning effect by using smartphone app as learning tool. In addition, we are trying to improve creative thinking ability, problem solving ability and logical thinking ability through early coding education. In this paper, we describe the learning and quiz app using the app inventor and conducted the related questionnaire. We developed a learning philosophy for preliminary early childhood teachers using the developed apps and taught them how to utilize them in early childhood education by explaining the apps and using the app inventor. Through questionnaires, we confirmed the learning effect and the willingness to use in early childhood education. Through this study, I hope to improve the ability of early childhood teacher learning and to utilize the coding in early childhood education with the app developed as the app inventor.

초등정보영재학생들에게 있어 스마트폰 앱의 개발은 기본적으로 자바와 같은 프로그래밍 언어 뿐만 아니라 기타 복잡한 프로그래밍 환경 등 어느 정도의 프로그래밍에 대한 지식을 요구한다. 본 연구에서는 전혀 프로그래밍에 대한 기초적인 지식이 없거나 앱에 대한 개발 경험이 없어도 쉽게 앱을 개발할 수 있은 MIT대학의 앱인벤터(AppInventor)를 활용하여 초등정보영재학생들의 창의성을 향상시킬 수 있는 앱 개발 교육프로그램을 개발하고자 하였다. 개발한 교육프로그램은 초등 정보영재 학생들의 창의성 및 문제해결력, 계산적 사고력을 동시에 길러 줄 수 있을 것이다.

We developed a motion capture system to get angle data of human joints in the walking mode. The motion capture system is a pair of leg-shape device, which is composed of three links with ankle, knee and pelvis joints. The sensors for measurement of the joint angle are potentiometers. We used an A/D converter to get digital data from joint angles, and which are used to simulate and coordinate the biped-walking robot developed in our laboratory. To simulate and analyze walking motion, animation based on three-dimension motion is performed using the open inventor software.
