학습 프로세스는 학습참여자인 학습자들과 교수자의 상호적인 활동에 의하여 교수-학습이 이루어지는 과정이라고 할 수 있다. 이러한 과정에서 일련의 학습자료들이 제공되고 만들어진다. 교수-학습이론에서 여러 가지 모델이 제안되어 이용되고 있지만 각 학습참여자의 역할과 학습자료간의 관계가 명시적으로 정의되어 운영되지 못하는 점이 있다. 한편 서비스제공이나 소프트웨어개발과 같은 추상적인 결과물을 생산해야하는 경영학이나 소프트웨어공학에서는 프로세스(과정)의 관리만이 그 결과물의 질을 담보할 수 있다고 생각한다. 결과물의 질관리를 위한 프로세스의 관리는 프로세스의 역할별 활동에 의한 투입/산출물, 프로세스들의 관계를 명시하고, 그에 따른 측정가능한 지표를 개발-분석함으로써 이루어진다. 본 논문에서는 소프트웨어 개발 방법론에 기반하여 구성주의적 교수-학습 프로세스를 정의함으로써 교수활동에 구성주의적 교수-학습이론을 용이하게 적용할 수 있는 지침을 제공하고, 향후 프로세스를 기반으로 하는 교육 서비스사이언스의 기본적 구성요소를 제공하고자 한다.

This study examined the effects of role rotation experience on learning flow, self leadership and debriefing satisfaction in nursing students. A non-equivalence control group quasi-experimental study was used and included as participants 203 junior nursing students at Y University. The experimental group (n=103) participated in the teaching class using a role rotation experience, while the control group (n=100) received conventional practice education. The outcome measurements were learning flow, self leadership, and debriefing satisfaction. The collected data were analyzed using a chi-test, and at-test using the SPSS WIN 21.0 program. The total score of learning flow and self leadership were similar in the two groups. On the other hand, in the case of the debriefing satisfaction (t=-2.70, p=.008), the experimental group ($4.24{\pm}0.51$) was remarkably higher than the control group ($4.03{\pm}0.60$). Although the changes regarding the learning flow and self leadership could not be identified, the debriefing satisfaction had been affected by the practice education using the role rotation experience. Therefore, to identify the effects of simulation education for further details, more research with diversified subjects and varied durations is needed.

Kamii는 피아제의 발생론적 인식론이란 이론을 모태로 수학을 지도해야 학습자가 수학을 이해를 바탕으로 학습할 수 있다는 믿음을 지니고 있다. 본고에서는 Kamii가 이런 신념을 갖고 실시한 수업을 녹화한 비디오 자료에 나타나는 특징을 분석하였다. 첫 번째 특징은, 교사가 가르쳐야 할 지식을 직접적으로 지도하지 않는 대신에 학습자가 스스로 지식을 구성할 수 있도록 매개자의 역할을 한다는 점이다. 두번째, 기저지식으로서 학습자의 비형식적 지식을 학습자가 적극적으로 활용할 수 있도록 허용하는 분위기이다. 세 번째, 두 번째와 관련되어서 학습자의 사고과정은 성인이나 학문적 체계에서 운용되고 있는 사고 흐름과는 다르다는 것을 인정해 준다. 네 번째, 교사의 역할이 가르쳐야 할 지식을 가르치는데(전수하는데) 있는 것이 아니라 학습자들이 생성해 낸 여물지 않은 아이디어들을 익힐 수 있도록 환경을 조성하는데 있다. 다섯 번째, 학습자마다 기저지식이 다르기 때문에 동일한 학습주제라 할지라도 이해의 폭과 깊이가 다르다. 따라서, 전체학급을 대상으로 하는 수업 중이라 할지라도 개별적 학습을 염두에 두어야 한다. 학생들의 수학적 이해력이 저하된다는 염려의 목소리가 높아지고 있다. 이는 학생들이 이해를 바탕으로 한 수업을 받아 보지 못하기 때문이며, 이런 원인은 아마도 교사 자신이 이해를 바탕으로 한 수업 경험이 간접적으로든 직접적으로든 없기 때문일 것이다. Kamii가 실시한 수업이 학생 스스로 수학을 학습할 수 있다는 구성주의 원리를 적용한 성공적인 사례이며, 이와 같은 방향으로의 교수법의 변화가 있기를 기대한다.

The damping parameter of Levenberg-Marquardt algorithm switches between error backpropagation and Gauss-Newton learning and affects learning speed. Fixing the damping parameter induces some oscillation of error and decreases learning speed. Therefore, we propose the way of a variable damping parameter with referring to the alternation of error. The proposed method makes the damping parameter increase if error rate is large and makes it decrease if error rate is small. This method so plays the role of momentum that it can improve learning speed. We tested both iris recognition and wine recognition for this paper. We found out that this method improved learning speed in 67% cases on iris recognition and in 78% cases on wine recognition. It was also showed that the oscillation of error by the proposed way was less than those of other algorithms.

This study investigated the effects of assigning cognitive roles, a method that may promote verbal interaction in knowledge-building processes, in small-group discussion for science concept learning. Two classes (62 students) of 7th-graders respectively received a concept learning instruction through small-group discussion with assigned cognitive roles (CR) asking to explain and contradict one's idea and to synthesize and conciliate group's idea, and a concept learning instruction through small-group discussion with no specific assigned roles (NSR), for 9 class periods. After the instructions, the tests of achievement, conceptions, the perceptions on science learning environments, and the perceptions toward small-group discussion were administered. ANCOVA results revealed that low-achievers in the NSR group performed significantly better than those in the CR group. Similar tendency was also found in the scores of the conceptions test. Two groups did not differ significantly in the perceptions on science learning environments and toward small-group discussion.

The purpose of this article is to investigate the relationship between children's goals and activities in terms of continuity and transformation of their learning through interactions between learners and practices across settings. By observing children's activities across settings and tasks and interviewing the children, I found that the continuity and transformation in learning are developed in the relationship between changing individuals and changing social context. In this process, social interaction with others plays an important role in changing their goals and strategies. The results imply that appropriate tasks and teachers' guidance are crucial to facilitate students' learning across settings.

In this study, to figure out the demands for learning, a survey was conducted on learning organization agents participating in learning organization project supported by public fund, through measuring their awareness level of the role and tasks drawn from the precedent study. This questionnaire was developed with four roles and twenty competencies drawn from the precedent study. After conducting the survey on over 200 small and medium corporations participated in learning organization project, the data was analyzed about the role and competency from 123 answer sheets collected. The results were as following First, the awareness of role importance was higher(4.36) than present level(3.73), and was important in order of innovator, operator, spreader, promoter. Second, in competitive importance of learning organization agents, the role of spreader was high, that of promoter was low. Third, in awareness level of learning organization agents, the demand level was generally high(4.1), but acquired level was generally low, so there was a wide gap between the demand level and acquired level. Forth, From the analysis result of those data about work competency of learning organization agents, learning organization promoter and learning leader, KMS operator ability and outcome were come out to be necessary, and next administrative ability about organization changes were come out to be necessary.
