Operating Systems is a discipline which handles complex and concepts related to its components and how an operating system works. However, most of the OS courses have been textbook-oriented theoretical classes. Therefore, many instructors have tried to make use of educational tools to help students understand a lecture and arouse their interests consistently. This paper describes the design and implementation of a web-based page replacement simulator which shows the process of page replacement algorithms visually. The academic achievement evaluation and t-test results for 2010's students and 2011's show that the differences of the correct answer ratios for the exam about page replacement algorithms and the scores between two groups are meaningful. And the results of survey show that a page replacement simulator is useful as an educational tool which causes the interests about operating systems and enhances the understanding of a lecture.

최근 다양한 ICT기술의 발전으로 인간의 사회, 문화, 교육 등의 많은 분야에 변화가 일어나고 있으며, 많은 기술들이 인간 삶의 영역에 적지 않은 영향을 미치고 있다. 그 중에서도 인터넷 웹 표준 기술의 발전은 e-book 시장과 교육용 콘텐츠의 변화가 많을 것으로 예측하고 있다. 따라서 본 논문에서는 N-Screen 지원과 반응형 웹 기술 지원을 위한 3차원 상호작용기반의 e-book 콘텐츠 저작도구 플랫폼 설계를 연구하였으며, 6가지 영역의 상호작용 콘텐츠 개발이 웹 표준에 의해 저작될 수 있는 저작도구 모형을 연구 개발 하였다. 본 논문에서 제안한 e-book의 저작 형태는 웹 표준 기술 HTML5와 ePub3.0 표준을 기반으로 제작할 수 있도록 콘텐츠 플랫폼을 설계 하였으며, 사용자와의 상호작용, 시뮬레이션 등의 기능을 쉽고 빠르게 제작할 수 있는 사용자 인터페이스를 연구 적용하였다. 향후 본 연구의 결과로 전자책 산업 발전과 교육 분야의 활용 향상을 기대하고 있으며, 지식의 체계를 좀 더 다양하게 제공 할 수 있는 e-book 콘텐츠 연구의 원천이 되기를 기대한다.

The purpose of this study is to develop cognitive scaffolding tools and to explore their effects on integrated science process skills of high school students. For this purpose, we developed cognitive scaffolding tools including one kind of classroom instruction for training integrated process skills and two kinds of individual learning materials that students can selectively study according to their level of inquiry ability. In addition, we developed hypothetico-deductive inquiry tasks as a tool to investigate the level of students on the integrated process skills for pre-test and post-test respectively. In order to verify the effectiveness of the cognitive scaffolding tools, we conducted inferential statistics on the pre-and post-tests of the experimental group and control group to examine statistical significance of students' inquiry level change depending on the usage of the cognitive scaffolding tools. We also produced Wrightmaps based on Rasch model to compare the change of inquiry ability depending on usage of the cognitive scaffolding tools. As a result, the experimental group using the cognitive scaffolding tools showed a significantly higher scores in all the components of integrated process skills namely, designing inquiry, collecting data, analyzing data, and forming conclusion than the control group. In addition, students who used cognitive scaffolding tools improved their inquiry ability and showed a distinct transition to higher level in each component of the integrated process skills. The results of this study suggest that high school students need cognitive scaffolding to alleviate or eliminate the functional barriers they face in conducting scientific inquiries.

Under the influence of the Fourth Industrial Revolution, there is a emphasis on capacity building based on computational thinking to foster talent for future. In Korea, SW education has been mandatory since 2018. Since 2017, research has been conducted on the definition of SW education capability and the development of diagnostic tools. At this time, the diagnostic tool for middle school has been revised and supplemented once in 2018 and is used so far. In response to the request from the field to expand the information diagnostic test for middle school to elementary school and high school, it began as one of the 2019 study on the effectiveness of SW leading schools. In this study, we develop a diagnostic tool for elementary and high school based on the diagnostic tool for middle school. Expert validity verification and preliminary inspections are carried out. Preliminary examinations will analyze the reliability, discrimination, and difficulty of the questions, and look forward to seeing the potential as a testing tool in the future.

현재 웹 상에서 진행되는 교육용 컨텐츠들은 날로 인기가 놀아지고 그에 부응하여 많은 교육용 웹 애플리케이션들이 만들어지고 있다. 그러나 증가되고 있는 컨텐츠 개발을 위한 기술과 도구들은 빠른 발전을 이루고 있는 반면 개발 프로세스에 대해서는 관심을 두지 않았다. 분석과 설계가 결핍된 상태에서 개발된 웹 애플리케이션은 품질 저하와 생산성 저하 등의 부정적인 파급효과를 가지게 된다. 따라서 교육용 웹 애플리케이션은 개발 초기에 적절한 모델링이 필요하다. 본 연구에서는 소프트웨어 공학 기술을 컨텐츠 개발에 적용하는 접근 방법을 사용하여 웹 애플리케이션 설계를 돕는 메커니즘을 제공하고 웹 기반의 맞춤형 교육을 위한 컨텐츠 모델링 방법에 관하여 논의한다. 웹 애플리케이션의 구성요소의 기호와 의미를 정립하고 교육용 컨텐츠의 구조를 정의, 분석한 후 웹 기반 시스템 모델링을 위한 구조로 재정의 한다. 적절한 모델링 과정을 거쳐 교육용 웹 애플리케이션을 개발함으로써 교육용 웹 컨텐츠의 체계적인 개발 및 관리 지원이 가능하게 된다.

This research supports the idea that manipulative devices can be an effective modality tool for learning abstract concepts involved with identifying geometric shapes and enhance learners' problem solving and motivation. Until recently specified manipulative device has been adapted only in traditional classroom environment and it has been very rare to find devices that is designed for online-basis. This study focused on designing and implementing an educational software which guide learners with geoboard in identification and characteristics of polygons. In addition to the function to draw and to delete various shapes, this software helps learners immediately assess the outcome. The results of the Delphi Technique show promising evidence for it being a very efficient means to learn geometric shapes and increase learners' motivation to learn the subject matter.

The purpose of this study is to analyze recently developed tools and relevant literature in order to discuss development scheme of augmented reality-based programming tools targeting elementary school students. Literature review draws conclusion that touch mode in the mobile augmented reality is effective, especially in the environment where manipulates commands and it is required to design contents taking class environment and teaching-learning strategy into account. Such research findings indicate that augmented reality-based programming tools targeting elementary school students should be designed to increase their interest in programming in a way that when physical teaching materials or specific space are recognized, the programmed problems will be augmented to allow students to combine the commands in the augmented environment.

On-Line Lectures are becoming more common due to the MOOK service and the expansion of national policy in Korea. Especially, It is being changed to new remote mixed style from traditional lecture in universities. We propose and implement a remote contents making tool with audio synchronization function based on more with less resources. To implement our proposed algorithm, we design an interactive interface to assign multiple cutting intervals and convert an input video to print a new result. In experimental, we can confirm our algorithm works properly with average performance value 9.3% cpu share ratio and 87mega byte ram usage(CPU 2.60GHz, 820*600 Area).
