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.

This study attempted to explore the guidelines for designing the contents of on-line learning in design field. The studies on the characteristics of design education and design major students as well as the guidelines for on-line learning were also reviewed. The guidelines for designing the contents of distance learning in design field were suggested through the synthesis and analysis of the former studies and the characteristics of design education and the learning style of Korean students. It could be concluded that the considerations were categorized into the following factors; quality of instruction, quality of presentation technique, quality of interaction, quality of evaluation and other surrounding factors. The finding can be used as a helpful guideline for the instructors of the design field who start on-line learning.

The development of information technologies has contributed on-line training as one of important education methods. On-line training in firms, which is similar to e-learning or virtual education, provides trainees with more education opportunities in diverse ways. It has developed a range of innovative services with a one-stop solution of education within the electronic sector. Also under the on-line training environment, trainees can undertake customized training packages at anytime and any places. Moreover, information technology allows both the trainers and other trainees to be decoupled in any of the elements of tune, place, and space. Two research questions are investigated : what are the determinants affecting the on-line training effectiveness and how those variables affect the two aspects of training effectiveness: learning performance and transfer performance. Based on the previous literature conducted on the traditional training environment, the determinants of training effectiveness are derived. Eight hypotheses are developed based on literature reviews and tested by questionnaires survey data. The collected data have been analyzed by LISREL. It is found that the relationship between individual, organizational and on-line site design variables and training effectiveness (learning and transfer) are significant. The contribution and limitations of this research are also discussed with future studies.
