This study is about an interface design supporting collaborative learning activities in online environment in which people exchange their knowledge and give feedback on personal storytelling to each other. Interface design issues from the viewpoint of Computer Supported Collaborative Learning (CSCL) on digital media design are considered. Based on collaborative learning theories and analysis on the existing online collaborative sites about digital media, such as online forums for digital pictures and films, interface guidelines are suggested and the interface is designed. The interface design is evaluated through a pilot test. The interface for collaborative learning on personal storytelling is designed to support observation and to provide a scaffolding for valuable conversation. It is also designed to help intersubjectivity of online conversation and an easy access to media.

학습자는 교수 학습 상황에서 대부분 배운 내용을 잉킹을 통해 정리한다. 교수자와 학습자 사이에서 잉킹을 통한 상호작용은 매우 중요하며 이와 관련된 다양한 연구가 진행되고 있다. 디지털교과서가 점점 보급되고 있는 상황에서 서책형교과서와 디지털교과서가 공존하는 현재의 과도기적인 교육환경은 일반적인 잉킹과 디지털 잉킹이 공유하고 있다. 이에 디지털 교과서를 활용한 협력적인 학습상황에서 과제를 제시한 후, 일반적인 잉킹과 디지털 잉킹을 학생들에게 그룹별로 각각 적용하도록 환경을 구성하였다. 본 논문에서는 일반적인 잉킹환경과 디지털 잉킹환경이라는 두가지 잉킹 방식을 적용한 후에 학생의 태도 및 판단, 문제 해결의 정확성, 학생의 선호도에 어떤 영향을 미치는지 분석하였다.

Web-based learning receives much attention as an effective learning method because users can use the learning service at any time from any space. A learning management system(LMS) provides online educational environment among teachers and students, supporting various facilities to deliver educational contents. Since most of the existing LMSs support one-way or limited two-way teaching services among teachers and students, there are a lot of difficulties in performing collaboration among students and/or collaboration among teachers and students. In this paper, we describe the development of collaborative workspaces which provides effective collaborative educational environment on Moodle which is widely accepted as a typical LMS. Through the provided various types of collaborative workspaces, users can easily perform group activities, sharing educational with appropriate access control mechanism.

As e-learning is recognized in new education form, Learning Management System that manage general activity of learning to maximize effect of education is being developed actively. Usually, Learning Management System includes course registration and learning as well as learner's learning recording and tracking, evaluation in online. But, most systems is lacking a tool that learners can collaborate with companion learners, and planning learning and set valuation basis as leading. In this paper, we can expect effective collaborative learning activities because can make debate and team project smooth by suggesting collaborative learning module that can drive voluntary participation such as group formation, learning plan, mutually estimation as leading to learner in Learning Management System of blended learning base that support online and offline environment both.

In this research, we applied a problem-based learning(PBL) method for one semester, and measured critical thinking disposition, self efficacy for group work and self confidence of nursing process of Nursing Process and Critical Thinking subjects before and after application. This research is one group pre-test and post-test design. The subjects of this study were collected using an online questionnaire for second-year nursing students located in G city, and 108 students participated in the final. The result of this research showed that critical thinking disposition(p=.000), self efficacy for group work(p=.003) and self confidence of nursing process(p=.000) increased statistically significantly after problem-based learning(PBL). This findings indicate that problem-based learning(PBL) is effective in improving critical thinking disposition, self efficacy for group work and self confidence of nursing process. Therefore, If problem-oriented learning (PBL) is expanded and applied to nursing education, it is believed that it will be effective in enhancing the core competencies of nursing students.

The purpose of this study is to present various examples of collaborative learning based on the Instruction of Internet in the 6th grade elementary school mathematics class. So we introduce the design method of classroom environment for classroom Internet and give example of various teaching methods. This study was conducted for nine months from March to November, 2016, one sixth grade of elementary school in D area. During this period, we conducted Instruction of Internet-based collaborative learning to classify typical teaching cases. We classified into 5 type collaborative learning. First, collaborative learning in the classroom. Second, remote collaborative learning between classroom and classroom. Third, Live participation classes. Forth, project collaborative learning. Fifth, using virtual reality in collaborative learning. In addition, we could identify that there is a difference compared to the conventional learning. It became possible to conduct collaborative learning with other students simultaneously or have opening class with both parents and teachers by using Youtube. These examples can be presented as a case to depart from traditional mathematics class in one classroom. In this regard, we will be able to provide several implications about teaching methods utilizing smart device and Internet in future classroom.

The study aims at investigating students' behaviors and perceptions regarding the collaborative learning based group project using the wiki environment. The study utilized Google Sites as a case, and analyzed file unloads, the use of web pages, navigation bars, and comments as well as surveys. The study discusses main characteristics of students' activities in the collaborative learning group project, which are drawn from the analysis of students' behaviors and perceptions. The study also provides implications for improvement of wiki environment to support collaborative learning in education.

In many applications, producing labeled data is costly and time consuming while an enormous amount of unlabeled data is available with little cost. Therefore, it is natural to ask whether we can take advantage of these unlabeled data in classification teaming. In machine learning literature, the co-training method has been widely used for this purpose. However, the current co-training method requires the entire features to be split into two independent sets. Therefore, in this paper, we improved the current co-training method in a number of ways, and proposed a new co-training method which do not need the feature split. Experimental results show that our proposed method can significantly improve the performance of the current co-training algorithm.

The aim of this paper is to develop a network-based collaborative learning system based on cooperative learning, computer simulation, role playing, and web-based instruction, which is called NetClass. It is an educational system of hybrid-type, and supports three learning modes as a distributed network, a stand-alone system, or a web browser. To accomplish the purpose of this paper, we have studied on the following topics. First, we selected appropriate learning contents among dilemmas on information ethics. Second, a Collaborative Dilemma-solving Learning Model (CDLM) was designed, and this model means systematic procedures that leaners can notice others' feeling and thinking and predict the results of his actions by introducing interactions among learners on computer networks. Third, Collaborative Learning System Model based on standard architecture of an educational system was proposed. Fourth, we developed many components such as network components, database components, and interface components.

Providing appropriate and cooperative work among learners is an essential factor of a successful educational authoring system. Although from the viewpoint of beginning authors, many authoring functions are employed in existing authoring tool, there has been little research to solve authoring difficulties by companion's assist and to keep pace with learning. Therefore, in this paper, we designed and developed a educational authoring tool using mathematical language and cooperative work among learners, verified the validity. The authoring tool proposed has key features to hide authoring handicaps and keep pace with learning and cooperate with each other by using networked and language-based authoring tool.
