  • Purpose: This study was conducted to compare blended practicum with clinical and lab combined e-learning between cooperative and individual group on learning outcomes. Method: A total of 63 junior Nursing students were recruited from C University in G city from May, 2012 to June, 2012. Ten hours lab practicum for two weeks was provided for both two groups during the period of adult nursing practicum. Prior to blended practicum, e-learning was conducted. For cooperative group, two hours off line team learning with a tutor for eight weeks was provided, in other hands, for individual group, any off line team learning was not provided and self study on line was not evaluated by the tutor. Results: The result of ANCOVA showed that critical thinking and self directed learning were significantly improved in the individual group compared to the cooperative group (F=-18.15, p<.001; F=28.12, p<.001). In other hands, clinical competence was significantly higher in the cooperative group than in the individual group (F=16.61, p<.001). Conclusion: Through development of self-leaning facilitating online contents, the blended practicum combined e-learning could be effective in critical thinking, self-directed learning and clinical competence. Further studies about e-learning strategies of off-line learning are still needed.

  • In this paper we suggest a general purpose RNN training algorithm which is derived on the optimal control concepts and variational methods. First, learning is regared as an optimal control problem, then using the variational methods we obtain optimal weights which are given by a two-point boundary-value problem. Finally, the modified gradient descent algorithm is applied to RNN for on-line training. This algorithm is intended to be used on learning complex dynamic mappings between time varing I/O data. It is useful for nonlinear control, identification, and signal processing application of RNN because its storage requirement is not high and on-line learning is possible. Simulation results for a nonlinear plant identification are illustrated.

  • This paper proposedan on-line learning controller which can be applied to nonlinear systems. The proposed on-line learning controller is based on the universal approximation by the local affine mapping-based neural networks. It has self-organizing and learning capability to adapt itself to the new environment arising from the variation of operating point of the nonlinear system. Since the learning controller retains the knowledge of trained dynamics, it can promptly adapt itself to situations similar to the previously experienced one. This prompt adaptability of the proposed control system is illustrated through simulations.

  • This study was to examine effects of On-Line Community Assisted Small Group Peer Tutoring(OCSPT) on university students' learning strategies. To achieve the purpose, twenty-eight university students were randomly selected. Fourteen students participated in OCSPT and they were divided into small groups consisted of 2 to 5. Students in experimental group participated in OCSPT for total thirty-four hours during sixteen weeks. There is no treatment for the other fourteen students in control group. To measure students' learning strategies, Motivated Strategies for Learning Questionnaire (MSLQ) shorts has been used. The result revealed that students in experimental group showed higher possession than control group in resource-management strategy(p<.05). However, there were no significant difference between both groups in cognitive and motivative strategies.

  • In this paper, we present a structure of personalized e-Learning system to study for a test formalized by uniform multiple-choice using on/off line mixed estimations as is the case of Driver :s License Test in Korea. Using the system a candidate can study toward the license through the Internet (and/or mobile instruments) within the personalized concept based on IRT(item response theory). The system accurately estimates user's ability parameter and dynamically offers optimal evaluation problems and learning contents according to the estimated ability so that the user can take possession of the license in shorter time. In order to establish the personalized e-Learning concepts, we build up 3 databases and 2 agents in this system. Content DB maintains learning contents for studying toward the license as the shape of objects separated by concept-unit. Item-bank DB manages items with their parameters such as difficulties, discriminations, and guessing factors, which are firmly related to the learning contents in Content DB through the concept of object parameters. User profile DB maintains users' status information, item responses, and ability parameters. With these DB formations, Interface agent processes user ID, password, status information, and various queries generated by learners. In addition, it hooks up user's item response with Selection & Feedback agent. On the other hand, Selection & Feedback agent offers problems and content objects according to the corresponding user's ability parameter, and re-estimates the ability parameter to activate dynamic personalized learning situation and so forth.

  • 본 연구는 사이버대학생을 대상으로 온라인 과제가치, 학교의 지원, 만족도 및 학습지속의향 간의 인과관계를 규명하는 것을 목적으로 하였다. 이를 위해 온라인 과제가치와 학교의 지원을 외생변인으로, 만족도와 학습지속의향을 내생변인으로 설정하고 W사이버대학의 2009학년도 1학기 재학생을 대상으로 웹 서베이를 실시하여 데이터를 수집하였다. 온라인 과제가치와 학교의 지원이 만족도에 미치는 영향을 검증한 결과, 이들 모두 만족도에 유의한 영향을 미쳤다. 온라인 과제가치, 학교의 지원 및 만족도가 학습지속의향에 미치는 영향을 검증한 결과, 학교의 지원과 만족도는 학습지속의향에 유의한 영향을 미쳤으나, 온라인 과제가치는 유의한 영향을 미치지 않았다. 추가적으로 만족도는 온라인 과제가치, 학교의 지원과 학습지속의향 간을 매개하는 것으로 나타나 변인들 간의 간접효과를 확인할 수 있었다.

  • Backgroud & Objectives: The purpose of the study was to develop an innovative blended learning method on life style and health promotion and evaluate the educational effects for university students. Methods: The blended learning was developed to combine face-to-face lecture(off-line lecture) and on-line lecture that applied the subject of life style and health promotion. This course is a coordinated effort towards providing 5 topics of lifestyle such as smoking, alcohol, exercise, diet, and stress management. This has been verified by an expert in the field of nursing, education, e-learning technician and students. Participants were different part of university students (n=28) with major enrolled in a general culture course for 2 credits which composed of 8 sessions of each 2-hour in the first semester of 2010. The study was a one group posttest design. A self-report about health knowledge, attitude, and health behavior was organized by content analysis after the sessions. Results: Positive feedbacks from students were reflected in the outcome. Student regarded good lifestyle as being the most important. Student concerned those on-line lectures are not only available at most time and site, but also good for individualization, visual understanding and interest. Face-to-face lecture provided student a chance to integrate with knowledge and experience and had desire to improve good lifestyle and health promotion. Conclusions: The blended learning method on good lifestyle and health could make a best use of improvement for knowledge, attitude and behavior concerning. It is needed to identify the long term effects of a blended learning for further study.

  • 최근의 정보기술 개발은 온라인 훈련에 기여하였으며 이러닝 혹은 가상 교육 등과 같이 유사한 개념으로 사용되고 있는 기업에서의 온라인 교육은 피교육자에게 다양한 방법으로 교육 기회를 제공하고 있다. 또한 전자적인 측면에서 일괄 서비스 체계의 솔류션을 제공하는 혁신 서비스로서의 기능을 제공하고 있으며 온라인 교육 환경하에서는 교육자와 피교육자가 시간과 장소에 구애받지 않고 개인화된 교육 패키지를 공급할 수 있게 한다. 본 논문에서는 온라인 교육에 영향을 미치는 요인들을 독립 변수로 하고 교육 성과와 전달 성과의 두 가지 측면에서의 교육 효과성을 종속 변수로 하는 관계를 실증적으로 검증하였다. 기존의 연구 결과를 기반으로 8개의 가정을 설정하고 설문서를 작성하여 LISREL을 이용하여 분석 한 결과 피교육자에 기인된 개별적 변수와 조직 변수가 훈련 효과성과 유의성이 있는 것으로 나타났다
