본 연구에서는 수술실에서의 간호오류 예방을 위한 간호사 대상의 교육을 목적으로 문헌고찰과 실제 경험한 오류사례와 요구도 조사 및 수술실 사건보고서 자료 분석을 통하여 사진, 음성녹음, 플래시 애니메이션, 동영상 자료를 활용한 사례중심 멀티미디어 학습콘텐츠를 개발하였다. 1시간 분량의 학습콘텐츠는 4가지 학습영역으로 구성되었으며, 학습영역별로 성우의 음성과 함께 플래시애니메이션을 활용한 실제 간호오류 사례를 이야기 형식으로 제공함으로써 학습자로부터 흥미와 현장감을 높였다. 또한 각 영역별 사례를 통해 학습자에게 비판적 사고를 유도하였고 표준화된 수술실 간호업무프로토콜을 대처방안으로 제시함으로써 교육의 효과성을 높이고자 하였다. 본 연구에서 개발된 학습콘텐츠는 신규간호사 뿐만 아니라 경력 간호사의 수술실 간호오류 예방을 위한 교육용 자료로써 실무에서 활용될 수 있기를 바라며, 콘텐츠의 지속적인 수정 보완을 위한 시스템 마련과 지원이 필요할 것으로 본다.

Over the years, there has been much research in blended learning. However, research regarding its use and evaluation is inconsistent, not following any specific evaluation method, and may not be applicable to local students. In this research, a case study was conducted to evaluate the environment based on three levels of Kirkpatrick's model. Methodological triangulation was the principle of data collection used in which multiple sources of evidence were triangulated to provide insights into this study. Instruments used include surveys, interviews, questionnaires and pre- and post-tests that are guided by Kirkpatrick's model. The results revealed that students were positive with the learning environment. Students enjoyed learning with multimedia and motivated to learn as well as engaged in the environment. The tests showed significant difference in their learning. Students also perceived that they have transferred their learning from face-to-face lecture into problem-based learning and learning outcome. This research contributes to the field by providing deeper insights into assessments in multimedia-based blended learning environment and empirical evidence on views, attitudes, learning and knowledge transfer of students in higher education.

The study described in this paper examined the effectiveness of a multimedia case-based learning environment to teach technology integration to Korean pre-service teachers. The structure and philosophy behind the use of embedded video in an online, multimedia system and the data collected from 103 pre-service teachers are presented and discussed. The overall finding shows that there was no significant difference from pre- to posttest among the lecture, the case-based, and the mixed environment groups. However, low prior knowledge students improved more when they learned about technology integration with the mixed method than with the case-based method alone. Discussion about this result and its educational implications conclude the paper.

본 연구에서는 멀티미디어 사례기반학습이 예비교사의 비판적 사고 성향과 수행능력에 미치는 효과를 검증하는데 그 목적이 있다. '특수아동의 이해' 수업을 수강하는 75명의 예비교사들 중 49명이 본 연구에 참가하였다. 실험집단에서는 실험 전 비판적 사고 성향 사전 검사 및 사전문제 분석을 실시하였으며, 13차시에 걸쳐 4개의 특수교육 관련 사례와 함께 현장 교사 동영상 인터뷰 등과 같은 멀티미디어 학습 자료를 제공하였다. 또한, 소그룹 및 전체 토론을 통해 각 사례에 대하여 다양한 의견을 공유하였다. 실험 후 비판적 사고 성향 사후 검사와 함께 새로운 관련 사례를 제시하여 이에 대한 분석 및 해결안을 제시하도록 하였다. 연구결과, 비판적 사고 성향에서는 집단 간 유의미한 차이가 나타나지 않는 반면, 새로운 문제 사례의 분석과 해결안을 통해 제시된 예비교사들의 수행에서는 멀티미디어 사례기반학습을 실시한 실험집단의 분석과 해결안 내용 및 완성도가 통제 집단보다 우수한 것으로 나타났다. 이를 통해 교사교육기간동안 멀티미디어 사례기반학습의 적용에 대한 시사점을 제시하였다.

In our fast-moving information and knowledge society, skills and know-how rapidly become outdated. Virtual learning environments play a key role in meeting today's growing demand for customized educational and vocational training and lift-long teaming. The scope of multimedia-based and web-supported education is illustrated by means of an interdisciplinary multimedia project 'New Statistics' funded by the German government. The project output contains more than 70 learning modules covering the complete curriculum of an introductory statistics course. All modules are based on a statistical laboratory and on a multitude of Java applets, animations and case studies. The paper focuses on presenting the statistical laboratory and the applets. These components present the main project pillars and are particularly suitable for international use, independently from the original project framework. This article also demonstrates the application of Java applets and other multimedia developments from the educational world to official statistics for interactive presentation of statistical information.

This paper investigated the effect of multimedia educational program developed based on Flash for learning how to make a part drawing of V-belt drive. The scholastic achievements of experimental group learned by the program were higher than traditional group in case of technical high school students, but they were not different in case of university students.

Core algorithm of deep learning Convolutional Neural Network(CNN) shows better performance than other machine learning algorithms. However, if there is not sufficient data, CNN can not achieve satisfactory performance even if the classifier is excellent. In this situation, it has been proven that the use of transfer learning can have a great effect. In this paper, we apply two transition learning methods(freezing, retraining) to three CNN models(ResNet-50, Inception-V3, DenseNet-121) and compare and analyze how the classification performance of CNN changes according to the methods. As a result of statistical significance test using various evaluation indicators, ResNet-50, Inception-V3, and DenseNet-121 differed by 1.18 times, 1.09 times, and 1.17 times, respectively. Based on this, we concluded that the retraining method may be more effective than the freezing method in case of transition learning in image classification problem.

In this paper, we introduce the sharable and reusable learning objects which are suitable for XML Web services in e-learning systems. These objects are extracted from the principles of pedagogical paradigms for reusable learning units. We call them LIO (Learning Item Object) objects. Existing models, such as Web-hosted and ASP-oriented service model, are difficult to cooperate and integrate among the different kinds of e-learning systems. So we developed the LIO objects that are suitable for XML Web services. The reusable units that are extracted from pedagogical paradigms are tutorial item, resource, case example, simulation, problems, test, discovery and discussion. And these units correspond to the LIO objects in our learning object model. As a result, the proposed model is that learner and instruction designer should increase the power of understanding about learning contents that are based on pedagogical paradigms. By using XML Web services, this guarantees the integration and interoperation of the different kinds of e-learning systems in distributed environments and so educational organizations can expect the cost reduction in constructing e-learning systems.

This paper presents a case study in which a lesson was designed and applied to enhance preservice home economics teachers' instructional design competence using the metaverse. For 15 weeks from March 6 to June 14, 14 students enrolled on the course 'Multimedia Home Economics Education' for preservice home economics teachers used the metaverse to engage in problem-based learning to solve instructional design problems in home economics classes. In accordance with the ADDIE design model, in the analysis stage, we assessed preservice home economics teachers' level of knowledge of lessons using the metaverse, and their perceptions of the possibility, necessity, and usefulness of using the metaverse in home economics lessons. In the design and development stage, lesson plans, questions for problem-based learning, assessment tools, and teaching and learning materials were developed. The implementation was conducted in parallel with training on understanding multimedia and the metaverse, and instructional design competence was evaluated through pre- and post-testing and reflection journals. The results revealed that the preservice home economics teachers acquired a good understanding of lessons using the metaverse, learned how to design lessons for self-directed learning by applying the metaverse to their home and classroom, and gained confidence in applying it to their teaching practice or in-service work. It is expected that the results of this study will be used as support materials for prospective and current home economics teachers to design home economics lessons using the metaverse, thereby expanding the horizons of home economics education.
