This paper aims to develop a map for optimized class space using ZEP among the metaverse platforms. As a research method, the classroom space was organized so that the subject of learning became a learner, and the classroom space was modified and supplemented to optimize while being applied to elementary school computer classes. The contents of the study investigated learners' prior perception of metaverse, and compared and analyzed the advantages and disadvantages of the metaverse platform. In addition, the map was designed by reflecting the results of the survey, and after applying the map to the class, necessary APIs and apps were installed to supplement it. As a result, the learner became the subject of learning in the metaverse space, freely identified the space, and actively participated in the class. In particular, we found that students who were passive offline and those who had a low participation rate due to lack of skills participated more actively. In particular, students who were passive offline or whose participation was low due to lack of skills participated more actively. If API and JavaScript programs are added to collect log data of learners for learning analysis, real-time feedback is possible for learners, and learner feedback is possible for instructors with statistical data. If this is possible, the metaverse space can fully expect the role of a learning assistant for learners and a teaching assistant for instructors.

The purpose of the study was to investigate the effects of social network centrality variables on students' performance in blended learning environment in a higher educational institution. Using data from 36-student course on Learning Theories and Their Implications on Instructional Design Practices, the researcher empirically tested how social network centrality variables - such as friendship network centrality, advice network centrality, and adversary network centrality - are correlated with academic achievement measures. Results indicate, as hypothesized, the friendship and advice centrality positively correlate with, whereas the adversary centrality being negatively correlate with application performance measures and test scores. The size and quality of posted online discussions are positively and strongly correlated with the advice network centrality.

This study is to design and implement the synthetic courseware that covers repeating learning, individual teaching, and effective teaching-learning games by using multimedia authoring tool KAS for numerical data of computer science which is especially a little boring and difficult to understand through blackboard-based lesson for senior high school students. It also overcomes the drawbacks of the existing CAI focused on text and image by combining various kinds of media like image, animation and sound effects. Animation of numerical data in the fields of radix conversion makes it possible for learners to check the individual learning process and visual interest. So it comes to increase the effectiveness of learning. Whenever each chapter is finished. learners' understanding can be evaluated by formative test. Applicability test of the developed CAI in Eumsung Senior High School. is statistically evaluated as more effective than that of the blackboard-based lesson.

Recently, as awareness of the need for software education has spread worldwide, the government of Korea has led compulsory software education also. Basic software education in universities has been stabilized through various trials and efforts. However, due to software classes are mandatory, students not only could not have motivation for learning but also have treated programming course as a difficult subject. In this paper, two programming classes, which were designed and managed as a problem-oriented programming class for the purpose of cultivating computational thinking for the non-computer science students, are compared using the lecture assessment results. As a result, in the case of expanding the use of the problem as a grammatical explanation aid and expanding the ratio of major-friendly problems, the student's responses were concentrated on higher scores and the response average improved by about 7%. It means that the level of difficulty experienced by learners is lowered.

Although vocabulary is one of the most important aspects in learning English, it is not dealt with as extensively as the grammar and reading comprehension in the classes due to time limitation. Furthermore, it is also dealt with in only a limited way at most of the English learning web sites compared to the other aspects such as grammar and reading comprehension. In this study. a web-based learning system for English vocabulary which allows a student to study the vocabulary before or after the classes by herself in order to supplement the English classes provided at school. Especially, it allows the students to learn the vocabulary within the context of sentences. It also provides an efficient structure for a repeated study of vocabulary that is new or difficult to the student.

The effects of computer-assisted instruction (CAl) using molecular-level animation and worksheet upon students' achievement, conceptual understanding, and learning motivation were investigated. Treatment and control groups (2 classes) were selected from a girls' high school in Seoul, and taught about dissolution for 3 class hours. Before the instructions, the Patterns of Adaptive Learning Survey (PALS) was administered, and the grade for a previous science course was obtained. The PALS score was used as a covariate, and the other as a blocking variable. After the instructions, the achievement test, the conceptions test, and the Instructional Materials Motivation Scale (lMMS) were administered. Two-way ANCOVA results revealed that the scores of the CAl group in the achievement and the conceptions tests were significantly higher than those of the control group. The CAl group also performed better in all subtests of the IMMS except the subtest of relevance.

The purpose of this study are (1) to analysis the Paradigm’s changes in Educational Technology, (2) to examine its practice in Home Economics Education (H.E.E.), especially the researches about CAI in H.E.E. and (3) to propose the ideal practice of Educational Technology in H.E.E. As results, the paradigms of Educational Technology have been changed from media-centered to human-centered, and from objectivism(behaviorism and cognitivism) to constructivism. Related on Educational Technology, there have been six conceptual distortions or confusions in H.E.E. The Analyzed seven previous works on CAI in H.E.E. show the traditions of the Objectivism. And suggestions for ideal practice of Educational Technology in H.E.E. are presented.

정보화사회가 도래함에 따라 교육분야에서도 다양한 교수와 학습활동을 실현할 수 있는 방법으로 컴퓨터의 활용이 중요성을 지니게 되었는데 그 중 중요한 방법 중의 하나가 강의실 수업의 연장으로써, 보조학습수단으로써 인터넷 서비스 중 웹(WWW)상의 교사 홈페 이지를 이용한 학습은 전통적 교수-학습 형태에서 볼 수 있었던 폐해를 극복하고 정보화시 대가 요구하는 창조적이고 능동적인 인간성을 길러내는데 일조하게 될 인터넷에 올려진 교 사 홈페이지를 이용한 교수-학습시스템인 것이다. 본 연구의 목적은 현재 몇몇 학교에서 실 시하고 있는 인터넷을 통한 교사 홈페이지를 이용한 교수-학습시스템의 구체적인 성과를 알아보고, 이에 영향을 미치는 요인들과의 관계를 밝혀 교사 홈페이지를 이용한 교수-학습 시스템의 좀 더 적극적으로 활용되었으면 하는 것이다. 시스템활용의 편이성과 시스템의 활 용도 그리고 학생의 학습 태도 등을 성과변수로 설정하고 학생의 시스템 활용능력과 교사의 홈페이지 구성내용 그리고 학교측의 지원 등을 주요 요인으로 설정하여 설문조사를 통하여 분석한 결과, 설정된 성과인 시스템활용의 편이성과 시스템의 활용도 그리고 학생의 학습 태도에는 긍정적인 측면을 나타냈고 이들에 영향을 미치는 요인들로는 공히 학생의 시스템 활용능력과 학교측의 지원으로 나타난 바, 이러한 시스템의 도입은 상당히 긍정적이며 앞으 로도 다각적인 연구의 필요가 충분히 있다.

This research was to assess the high school girls' need about the computer assisted instruction(CAI) in the Home Economics Curriculum. In One-way ANOVA, the high school girls' need about the CAI differs in the educational level of the father and the mother, the preference for the Home Economics, the involvement with the Home Economics and the preference for a teaching method of Home Economics. MCA was done to assess the independent explanatory power of predictory variables. The educational level of father and mother were included separately in different model. The MCA that the educational level of father was included in, The most influential variable was the preference for the Home Economics and the involvement with Home Economics was the second. The MCA that the educational level of mother was included in, The most influential variable was the preference for the Home Economics and the educational level of mother was the second.

It is information age now. Computer technology increases productivity, efficiency, and convenience of the public. Even if the computer-aided mathematics education is very important, so far there is the meager level of applying computers to mathematics education. This paper proposes a learning system with authoring tool for mathematics education. Teachers make study-contents easily with the system, and use them on a class. The content database that stores study-contents extends the usability of the system.
