Software education is required from elementary schools to prepare students for the fourth industrial revolution, which aims to improve algorithmic thinking. In general, teaching is divided into two stages: using a flowchart to design algorithms and implementing them through programming. However, converting a flowchart into code and checking the results in an educational programming tool is time consuming and requires additional programming activities. This study proposes a tangible coding tool that enables elementary students to convert algorithms designed at the unplugged activity into educational programming tool codes. This tool was developed in order for students to design algorithms at the level of assembling paper blocks and input them into a programming tool by taking a picture. Sixth graders were participated in this activity to evaluate its usability.

The purpose of this study is to develop math anxiety scale for middle school students for planning and implementing math anxiety treatment programs. In this study, we describe the process of developing and validating math anxiety scale for middle school students and detailing exploratory factor analysis and confirmatory factor analysis to verify construct validity. As a result of the study, we developed the Math Anxiety Scale for Middle School Students (MASS-M) of 30 items with four factors: mathematical curriculum content, mathematical attitude, mathematical test, and environment. As a math anxiety factor for middle school students, MASS-M was developed, which includes mathematical anxiety factors such as mathematical test factor and environmental factor, especially mathematical curriculum content factor describing mathematical treatment, and mathematical attitude factor describing psychological treatment. MASS-M, derived from this study, is a standardized scale for measuring math anxiety in middle school students and is expected to serve as the basis for maintaining consistency in research on math anxiety in middle school students and developing programs to treat math anxiety in middle school students.

Operating Systems is a discipline which handles abstract concepts and techniques. However, most of OS courses have been textbook-oriented theoretical classes. Theoretical classes lead to the decline in the understanding of a lecture, and hurt their concentration. Many instructors have tried to make use of educational tools to help students understand lectures and arouse interests. This paper describes the design and implementation of a CPU scheduling simulator which shows the operation of process scheduling algorithms visually. The academic achievement evaluation for 2010's students and 2011's and t-test results show that the differences of the correct answer ratio for the exam about CPU scheduling algorithms are meaningful. The survey shows that the simulator is useful as an educational tool which causes the interests and enhances the understanding of a lecture, this teaching method is effective to develop problem solving skills.

Recently, domestically and abroad, programming education has become more important and this increase has been recognized. And it needs a certain criteria for a selection of programming tools because there are various educational programming tools coming out. Thus, we tried to develop a criteria on the selection of educational programming language for a novice programmer and K12 students and verify its validity. So we established 4 areas and 28 items for selection criteria on educational programming language. Additionally, we carried out delphi survey and analyze for validity verification on selection criteria established. As result of carrying out of these processes, we developed 4 areas of selection criteria. Finally we have chosen 19 selection criteria and excluded 9 criteria items which are not sufficient with validity criteria through delphi survey.

본 연구는 교육현장의 교수자가 직접 앱 저작도구를 이용하여 교안 및 교육 내용을 개발하여 학생들이 시간과 장소에 상관없이 효율적인 학습을 하도록 하는데 있다. 현재 스마트폰이나 태블릿을 이용한 교육에 관심이 많으나 영역 전문가인 교사와 프로그램을 개발하는 개발자 사이에 의사 교환의 어려움 등으로 인해, 만족스러운 양과 질의 컨텐츠 개발이 이루어지고 있지 않다. 따라서 교수자는 앱을 프로그래머에 의뢰하지 않고 저작도구를 이용하여 DIY(Do It Yourself) 앱을 개발함으로서 학습내용을 충분히 만족하며, 강의 진행중에서 컨텐츠 변경이 용이하며, 교수자와 학습자와의 커뮤니케이션의 효과와 학습능률을 높이고자 한다.

Educational programming languages help learners to easily understand and use computer system itself. They also enhance the reasoning power and the contemplative faculty of learners. However, in spite of the importance of educational programming languages in education, there has not been much research and development on them compared with general purpose programming languages. In this paper, we propose and examine a new educational programming environment TWo (Turtle World) which is designed for learners to utilize the recent information technologies. Aimed at being used as a learning and working tool for multimedia programming and processing, TWo is a web-based reflective object-oriented Hangul programming environment which provides each learner with the learning environment according to his intellectual ability to learn.

전통적인 교수.학습의 형태를 벗어나 새로운 환경인 웹을 통한 교육이 이루어지고 있다. 그러나 대다수의 웹을 통한 교육들은 단지 웹 환경이라는 이름 하에 평면적인 의사소통의 한계를 벗어나지 못하고 있는 실정이다. 이에 대한 대안으로 본 연구에서는 가장 대중적인 실시간 의사소통 프로그램인 채팅 프로그램을 기반으로 교육용 대화 애플리케이션을 개발하였다. 이 애플리케이션이 교실 내.외적으로 열린교육에 대한 지대한 관심을 쏟고 있는 최근의 학교 교육에 하나의 학습 도구로서 활용될 수 있음을 기대한다.

Energy saving is becoming more and more important issue due to lack of resources and limited nature. However, There is a lack of learning status on energy saving in the school field. In particular, in elementary education on energy saving was not linked to practice, and the educational effect was insufficient. Although various kinds of learning tools are utilized, many successful cases of energy saving game strategy are introduced in overseas industry field, and game design is proposed so that energy related education can be played through games. Because energy conservation can not be effective without practice, learning using games as a tool is expected to be more effective than learning based on knowledge transfer in the classroom. We propose a defense game for energy conservation education by using the mission elements, score acquisition element, time limit element, and character element which are the interesting elements of the game designed in the previous research.
