Authentic programming environment makes App Inventor interesting educational programming language. However, there are not sufficient studies for usefulness of App Inventor as educational programming language, so proper design of App Inventor education is not available. This article aims to design proper programming education plan using App Inventor. A survey was conducted to ask for appropriation of App Inventor education to teachers and students. As a result, teachers and students were satisfied with App Inventor for programming language in elementary and secondary schools, due to easy-to-use programming environment and real product run in their devices. But learners need to have prior knowledge to use App Inventor and teachers have to manage learners' devices properly. Finally, revised elementary and secondary programming education plan using App Inventor was presented.

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.

이 연구는 스마트교육환경에서의 교육용 앱을 평가하기 위한 신뢰롭고 타당한 도구를 개발하는데 있다. 기존 선행연구에 기초해서 교육용 앱의 평가를 위한 평가모형을 도출했으며, 이 모형은 4개의 평가영역(교수 학습측면, 화면디자인측면, 기술측면, 경제 윤리측면)과 13개 평가요소들로 구성되었다. 이 잠재모형의 통계적 타당성 검증을 위한 자료수집을 하고자, 경기도 소재 중학교 1곳과 고등학교 2곳의 학생 156명을 대상으로 교육용 앱을 평가하는데 있어서 각 평가문항이 갖는 중요도를 평가하였다. 수집된 자료를 탐색적 요인분석한 결과, 교육용 앱을 평가하는 영역으로 교수 학습(흥미성 자기주도성 실용성, 인지발달성), 화면디자인(디자인의 적합성, 어휘의 정확성), 기술(호환성, 안정성), 경제 윤리(경제성, 윤리성) 등 4개 영역이 제안되었다. 또한 문항내적일관성을 확인하고자 신뢰도 분석한 결과, 각 평가영역 별 Cronbach ${\alpha}$는 .88, .85, .82, .80으로 모두 적합한 수준을 보였다. 따라서, 이 연구를 통해 도출된 교육용 앱 평가도구는 통계적으로나 타당성과 신뢰성 측면에서 의미 있는 것으로 판단할 수 있다.

디지털 콘텐츠의 한 형태로 볼 수 있는 앱은 개발자들의 창의적 사고를 바탕으로 현재도 무수히 쏟아져 나오고 있으며, 많은 사용자로부터 선택되어 활용되고 있다. 이러한 변화는 교육분야에도 영향을 주어 앱을 활용한 교육환경과 교육방법에 대한 다양한 연구가 현재 진행되고 있다. 앱과 같은 디지털 콘텐츠의 개발은 창의적 아이디어를 기반으로 구현되며 이는 콘텐츠 사용자의 유용성과 경제적 가치를 결정하는데 중요한 요소로 작용하고 있다. 이러한 창의와 디지털 기술을 접목한 앱 프로그래밍 교육은 학생들의 창의적 사고와 문제해결력을 향상시키는데 중요한 역할을 하며 특히 교육용 프로그래밍 언어(EPL, Educational Programming Language)를 활용한 코딩 교육과 창의적 문제해결력 향상에 관한 관련 연구들이 활성화되고 있는 실정이다. 본 연구에서는 이러한 EPL을 바탕으로 비IT계열 전공의 대학생들에게 프로그래밍 교육을 실시하고 창의적 사고를 통해 디지털 콘텐츠인 앱을 제작하는 것에 초점을 두기 위한 안드로이드 앱제작 교육 프로그램 개발을 진행하였다. EPL을 위한 도구는 MIT 미디어랩에서 개발한 클라우드 기반의 안드로이드용 앱 인벤터2(App Inventor 2)를 사용하며, 제작한 앱을 스마트 기기에서 즉시 실행하고 확인할 수 있다는데 대해 학습만족도와 성취감이 높음을 수업관찰을 통해 확인할 수 있었으며 제작 과정에서도 활발한 사고력를 발휘하는 것을 확인할 수 있었다.

본 논문은 사전 데이터를 바탕으로 한글 뜻풀이를 하여 한글 단어를 맞추는 앱 어플리케이션 '한글아 놀자'의 설계에 대하여 서술한다. '한글아 놀자'는 게임을 통하여 사용자가 쉽게 한글 단어를 학습 할 수 있도록 만들어진 앱 어플리케이션으로 기존의 유아를 대상으로 하는 유사한 어플리케이션들과 달리 특정 층을 대상으로 잡지 않아, 일반인도 흥미를 가지고 학습 할 수 있고 따라서 다양한 사용자 층을 확보 하여 한글 학습의 접근성을 향상 시킬 수 있도록 하였다. 또한 어플리케이션의 중요한 특징 중 하나로 게임을 진행 하며 잘 몰랐던 단어들은 오답 노트를 통하여 피드백을 해주고, 사용자의 선택에 따라 자신의 단어장에 추가하여 언제든지 복습해 볼 수 있도록 하여 지속적인 학습이 가능하도록 하였다. 그 외에도 '한글아 놀자'는 사전 데이터를 가지고 동작하기 때문에 일상생활에서 잘 쓰이지 않는 단어, 옛말, 사자성어등도 학습이 가능하도록 하여 한글의 활용성을 높이고 사용자가 접하는 단어의 다양성을 높이는데 주력하였다.

The purpose of this study is to verify the educational effectiveness of interaction design in mobile APP by observing the impact of interaction design for elementary school education on enhancing learning immersion and continuous use intention, and propose an interaction design scheme based on elementary school education APP. The research methods are literature research and questionnaire survey. Specifically, through the literature research method, the concepts and prior studies on the concept, reviews the continuous use intention and previous research of interaction design. Then, conducts a questionnaire survey on elementary school students in South Korea and China to understand the interaction design, learning immersion, and continuous use intention, and analyzes the relationship between variables.The research result of this study is to observe the influence of interaction design elements within interaction on learning immersion and continuous use intention with elementary school students who are users of elementary school education application as the objects. The results show that interaction design within interaction has a positive impact on improving learning immersion and continuous use intention. It can be thought that this is because in mathematics/science education, it is easy to understand theoretical concepts or explanations, and stories and images will be continued at each stage to help students learn without being bored.In conclusion, this study can confirm that interactive inline design has a positive effect of enabling learners to engage in learning and continue to use.

Excessive cognitive burdens caused by learning grammar should be reduced to cultivate high-level thinking skills in students through programing education. To this end, various educational programing languages have been developed. In recent years, block-based App Inventor that can used in real life have been introduced. This study intends to suggest an educational environment in which programing can be utilized as a leading problem solving tool by designing and producing an app that can be easily used by students in their real life. In particular, given the developmental phase of elementary school students, specific operational activities are important. For this reason, an App Inventor that can be proposed to enable dynamic interactions with the real world based on various smartphone sensors during the process of programing has significance as an educational programing language for elementary school students. In this regard, this study designed App Inventor programing education for elementary school students, which can be used in their daily life. The results of applying the education in fifth graders showed its positive effects on learning programing. LT collaborative learning where the students cooperated with each other, the theme of learning, which enables the utilization of various smartphone sensors in real life, and the app inventor may have generated and sustained the students' interest and attention.

Most of the APP market today, it is biased in the field of games and entertainment. In contrast, market-share of the educational APP is very low. This phenomenon is due to two major problems. The first is a decrease in the reuse because of the test of simple pattern. The second is difficult to consider user-level range that was learned previously. In this case it is necessary for students to do additional effort. This paper, propose an educational intelligent educational APP to solve the problems described above and shows implementation results. This system analyzes the stored results that have been saved to determine the area of vulnerability. Time-based Re-validation module helps long-term memory of student. The proposed system in this way directly supports self-directed learning. Therefore, the students can be able to relearn weak area autonomously. It results in improved academic achievement.
