This paper introduces a class model based on a course, Internet English, offered by an English department at a university. The course has dual purposes of developing students I English skills and Internet using skills at the same time. In support of using the Internet for language learning, the advantages of project-based language learning and constructivist learning in relation to CALL are explored. The activities in this course, which are basically project-based under the paradigm of constructivist learning perspective, are explained in detail to show the relationship between second language learning theory and teaching application. The way how the four language skills - speaking, listening, reading, and writing - are integrated in this class is described as well. Finally, judgmental evaluation of the course by the students is noted. The results show that a project-based CALL class could be a promising class model to realize an integrative, constructivist, and authentic learning.

지식 기반 사회를 바탕으로 한 정보화 시대인 21C에, 특히 초고속 통신망의 실현으로 인터넷을 누구나 쉽게 접근하여 사용할 수 있게 됨으로써 우리 수학교육도 적극적으로 컴퓨터를 이용한 Web상에서의 실시간 교육의 도입을 필요로 하게 되었다. 이에 따라서 사이버 공간을 통한 교육이 부각되고 있으며 학습자를 대상으로 한 다양한 수업모형의 개발이 활발하게 진행되고 있다. 그러나 현재 대부분의 웹상의 수업모형들은 학습자가 접근하기가 어렵다거나 단순히 내용을 나열하는데 그쳐 학습자의 능동적인 참여의 유도에는 많은 문제점이 있음을 알 수가 있었다. 이에 본 연구는 다른 과목과는 달리 대부분이 추상적인 지식체계로 구성된 고등학교 수학교과 중에서 학습자가 다소 어렵게 생각하는 여러 가지 대수함수의 그래프를 FlashMX의 액션 스크립트를 이용하여 시각화함으로써 Web상에서 학생 스스로가 언제 어디서나 원하는 함수들을 직접 설정하여 즉시 역동적으로 변화가 가능한 그래프를 그려보고 확인함으로써 보다 정확한 이해를 도울 수 있도록 하였다.

정보 통신 기술의 발달로 컴퓨터를 활용한 교육 영역이 계속 발전해 나가고 있고, 교수-학습에 도움을 주기 위한 많은 코스웨어 들이 개발되어 사용되고 있다. 기존의 코스웨어는 수업시간에 이미 배운 내용을 단순 반복하거나 형성 평가 형식의 예제를 풀어보는 유형으로, 학습자는 미리 계획된 커리큘럼과 프로그램에 수동적으로 반응하게 되어 코스웨어에서도 교수 중심의 학습이 이루어 지는 것을 극복하기 위해 본 연구에서는 학습자가 능동적으로 학습 과정에 참여하여 학습자 중심의 교육이 이루어 질 수 있고 텍스트가 아닌 프로그래밍 언어나 아이콘화 된 메뉴를 이용해 쉽게 접근이 가능하며 실제 상황과 유사하게 학습환경을 제공하고 수행결과를 확인해 학습의 효과를 극대화 시킬 수 있는 응용 프로그램 인터페이스(Application Program Interface) 기반의 시뮬레이션형 코스웨어를 설계해보고자 한다.

Teachers should be able to reorganize the curriculum according to the student level, reorganize textbooks freely, and distribute them to students. However, current paper-textbooks are difficult to modify or edit some contents and distribute them to students, also current digital textbooks are grouped into units, so the order or educational resources cannot be reconstructed. In addition, The digital textbooks are difficult to update external links or the latest resources, and to contain various multimedia materials or high-definition realistic content due to capacity limitations. Therefore, this study presented functions: teaching and learning and evaluation functions, resources search and sharing functions, learning records and analysis functions, screen showing and printing functions, so that teachers can provide customized learning by level to students using digital textbooks. Through the expert Delphi survey, detailed functions for each area were divided into teachers and students. We proposed expanding and developing digital textbooks to various subjects, and distributing various teaching and learning models using digital textbooks.

Artificial intelligence clouds help to efficiently develop the autonomous things integrating artificial intelligence technologies and control technologies by sharing the learned models and providing the execution environments. The existing autonomous things development technologies only take into account for the accuracy of artificial intelligence models at the cost of the increment of the complexity of the models including the raise up of the number of the hidden layers and the kernels, and they consequently require a large amount of computation. Since resource-constrained computing environments, could not provide sufficient computing resources for the complex models, they make the autonomous things violate time criticality. In this paper, we propose a digital twin software development framework that selects artificial intelligence models optimized for the computing environments. The proposed framework uses a load estimation DNN model to select the optimal model for the specific computing environments by predicting the load of the artificial intelligence models with digital twin data so that the proposed framework develops the control software. The proposed load estimation DNN model shows up to 20% of error rate compared to the formula-based load estimation scheme by means of the representative CNN models based experiments.

In this paper, presents an efficient education method for training specialized edutainment SW education instructors and drone realistic media creators, not just training to acquire certificates through drone manipulation training. To this end, the NCS-based curriculum was derived. The developed curriculum includes the edutainment drone curriculum and the realistic media creator curriculum. Among them, core responsibilities were defined for the drone control curriculum and core tasks, knowledge, and attitudes were described for each. After that, a detailed curriculum for drone control was derived. In the realistic media creator curriculum, pilot education was conducted to actually produce advertisement videos to foster experts who can work directly in the industrial field. Finally, through holding an online conference in a metaverse environment, a virtual conference was operated to share and discuss media videos produced by trainees. After the end of education, the efficiency of this curriculum was proved through education satisfaction analysis for 46 education graduates. This paper presented a method to achieve internalization of SW education in non-face-to-face online education that our society must solve after post-COVID-19. In addition, an efficient educational method in a realistic media environment was suggested by showing a realistic media creator training curriculum, pilot programs, and metaverse conference management cases.

This study analyzed status and demand of participation in lifelong education for 218 residents of low-income class according to National Basic Livelihood Security Act. The results of the study are as follows. First, among the statuses of participation in lifelong education, the abilities to study of the low-income class were reviewed. They showed 95.3% of foreign language ability, 66.1% of ICT utilization capacity and 75.7% of computer literacy ability. And the lifelong education participation rate of low-income people was 75.7% It was considered as passive participation in education. Voluntary participation was identified and analyzed. The the actual participation rate in lifelong education was very low at 22.9%. Social participation and awareness according to participation in lifelong education was 43.3% higher than that of respondents who had no participation experience. Especially, voluntary participants showed 73.3% higher than those who did not participate. Second, as a result of analyzing lifelong education of low income class, 74.8% of the respondents answered that there is wished education program. And 50.0% of them could not participate because they did not have enough time. The programs that they wanted to participate in were the programs that could help their real lives such as home life, health and medical courses, professional qualification obtaining process, etc. This indicates that the income level plays a significant role in participation in lifelong education. As a result of analyzing the results of this study above, Korean lifelong education is emphasized and the participation rate is increasing rapidly. However, participation of low-income class in lifelong education seems low.

DTP is an innovation of publishing arts act up to the social environmental change followed by the development of the computer and using a word processer. which makes us more convenient and economical. beside. consumer's various desires for design. DTP is getting more practical owing to convenience and economization. but. There is a limit on creativity by the typical working environment. Especially. A convenient tool environment has reduced the field of creativity on account of its consistency with only solving design problems. Result of study. The tool environment has rapidly improved in working environment and process compared with the handwork editing in the past. Particularly. Accidental creations caused by the computer program probably could narrow down the idea world with consistency which is expressed as a pleasure creation. Therefore. A design idea and process should be examined sufficiently by idea sketch before using a computer for original editing. And. As editorial design is based on the aesthetic formative principles. there should be not only how to operate by the tool but also a basic editing design instruction sufficiently for the electronic page design.

The purpose of this study is to find out the changing trajectory of online game use as the development of early adolescences. It is also to explore whether the self-control has a current and a lag effect on the game use while development of students. We found these results: (a) There is a statically significant individual variability in initial levels and rates of change in online game use over time. The change of trajectory is declined. (b) Boys also have higher rate of the change in using game than girls over time. (c) Both initial state and changing rate of online game use affects negatively the academic achievement. (d) Current effect always supports, but lag effect does not support except the period from last elementary school grade to middle school grade as explanations for the developmental relation between self-control and online game use in young adolescents.
