Executive SummaryThe evolving growth in networking and telecommunication technologies leads to their enhanced usage in many and different aspects of human activity. One of the technologies that shows great interest is Collaborative Virtual Environments (CVEs), which may be used in various applications, such as tele-education. This paper presents, analyzes and evaluates the basic elements of Elearn, a Collaborative Vi rtual Learning Environment (CVLE) that has been created for teaching electronic commerce. In Elearn, the virtual world, the web pages and the synchronous chat among the participants are integrated into the same environment. A user is represented as an avatar who can move, make gestures with its hands and head, bump into objects, pass through them, etc. A detailed list of navigation directions is provided in order to help the user to move freely into the environment. The possibility of many users to coexist in Elearn is also supported. Collaboration and cooperation are its two components that enhance the learning effectiveness. Collaboration is supported among students and teachers with the use of synchronous chat. The chat window appears on the screen along with the virtual world and the web pages, motivating the participants to use it. Asynchronous communication is also supported, via email and discussion board.The evaluation of a CVLE is an important and difficult task. Pedagogical issues, like conceptual learning, collaboration, constructivism and adaptability, should be taken under serious consideration. These parameters are crucial in achieving strong learning effectiveness. An evaluation table has been developed which includes all the important parameters concerning a CVLE. The evaluation is performed at four levels: 1) the pedagogical -psychological level, 2) the technical -functional level, 3) the organizationaleconomical level, and 4) the social -cultural level. Elearn was used in an experiment supplementing traditional teaching. The students' participation was satisfactory, since they demonstrated great interest in exploring Elearn and using the synchronous chat capability. The basic pedagogical issues, like constructivism and collaboration, were fulfilled, but greater effort is needed towards the development of the lessons' content and exams. Students and teachers communicated via synchronous chat and email, as well as using the teacher's bot (an avatar that inhabits the virtual world and interacts with users). A lot of time was invested in developing and managing Elearn. Despite all the difficulties, we believe that the new methods of teaching, using CVLEs and innovative pedagogical approaches, enhance the traditional teaching methods and improve the student participation.
Computer supported collaborative learning environments (CSCLEs) is one of the innovative technologies that support online education. Successful design and implementation of such environments demand thorough analysis of many parameters. This chapter studies the impact of diversity in learner-learner interactions in collaborative virtual teams through a social and cultural perspective. Social differences include gender, race, class, or age. Cultural differences refer to matters like how an individual’s cognition, values, beliefs, and study behaviors are influenced by culture. Instructors must take into consideration the factors that influence individuals’ diversity, and invent new ways to implement successful collaboration. This is crucial, especially regarding teams scattered on different countries or even continents. Social and cultural differences influence an individual’s performance in a learning environment. Such differences must be adequately studied by both the educational organization and the instructors in such a way that the learning procedure will become a positive experience for all the members involved.
