As an important means of information security and copyright protection, digital watermarking technology has been extensive researched and widely applied; it proves data's ownership or integrity by embedding secret information into raw data, thus achieves the purpose of copyright protection and information security. Based on the analysis and research of wavelet transformation, this study achieves to...
In this essay, we present an experience held in a subject of Civil Engineering. The activity consists of the students integrating a virtual forum, which makes possible an exchange of ideas between them and the integration of concepts through problematic raised situations. In this way, we aim to perform a collaborative work as well as to develop critical thinking, and at the same time we face the students...
This paper presents a study of the learning process in a distance collaborative learning environment with a chat system and a Wiki, and development of a new chat system based on the study. Collaborative learning as the combination of conversation and collaborative work was investigated, which revealed 1) There is a time lag between conversation and work, 2) Awareness of other learners is problematic...
The purpose of this study was to investigate how to design an efficient collaborative learning model to develop a constructing consensus framework through CSCL. Our proposed mechanism employs binary tree structure and heterogeneous method to assign and organize the collaborative group. This study used the Web-based environment to carry out a series of collaborative learning activities and to facilitate...
Task allocation mechanism via coalition formation is one of key problems in the multi-agent systems. To solve the question of current single form of distance education system and passive teaching, the paper discusses learning task allocation question of learning system by the state space solving model and presents an algorithm for multi-agent collaborative learning task allocation based graph framework...
With the development of computer network and modern instructional theory, collaborative learning has become an important instructional strategy in the environment of cyberschools, and it can help develop many important characters of learners, such as creativity, collaboration with people and so on, which are valued highly in modern society. This paper firstly introduces collaborative learning and...
With the development of information technology (such as computer network, etc.) and the renovation of education ideology, the network course already became an important constituent of the distance learning resources, also the network collaborative learning has become a hot research area in contemporary education. But the study efficiency is to be low in network cooperates on the present, the learner...
This research is to present the form of learning method through internet network called "collaborative leaning", including the attitude of teachers and students toward "collaborative learning", the form of learning method through internet. The developed learning method through internet network consists of; 1) learning management system, 2) course management system, and 3) seminar...
This paper presents an approach for closely observing the different levels of human and computer interactions during studentpsilas communication activities on computer mediated communication (CMC) tools. It focuses on how to efficiently track learnerspsila activities, along with their outputs, and to exploit the collected tracking data in order to assist participants, both learners and teachers, in...
Asynchronous discussion forums are used increasingly in e-learning in which learners interact in academic and social contexts, whereas some challenges and difficulties exist pertaining to the activity and variability in learner participation and collaboration. To motivating and facilitating active collaborative learning, this paper describes the design of an enhanced asynchronous discussion forum...
This paper presents the adaptation model used in NUCLEO, a pilot e-learning environment that is currently being developed at the Complutense University of Madrid. The NUCLEO system combines two approaches grounded in the constructive pedagogical stream, the Computer Supported Collaborative Learning and the Problem Based Learning, with the engaging and immersive formats of the videogames. It provides...
Mobile learning, a natural extension of distance education, supported by wireless mobile technologies is an emerging pedagogical learning model which requires new forms of teaching and learning. Being aware of the importance of this standard, we held a series of educational experiments utilizing mobile devices such as mobile phones and MP3/MP4 players to evaluate the implications of mobile technologies...
This paper presents our work on netUniversity web portal, an easy and competitive solution dedicated to the creation and management of pedagogical online content. netUniversity provides a wide diversity of pedagogical models based on IMS-LD, which offers the best adaptation of courses to the chosen pedagogy and learning style. Our tool gives teachers the possibility to edit their own pedagogical scenarios...
The discussion process plays an important social task in computer-supported collaborative learning (CSCL) where participants can discuss about the activity being performed, collaborate with each other through the exchange of ideas that may arise, propose new resolution mechanisms, as well as justify and refine their own contributions and thus acquire new knowledge. Indeed, learning by discussion when...
While the ongoing information technology (IT) revolution is providing us with tremendous educational opportunities, educators and IT researchers face numerous obstacles and pedagogical questions. The Georgia Institute of Technology (Georgia Tech) has a long history in engineering education research and has developed and designed many different tools for instructor authoring, course capturing, indexing,...
