Collaborative Learning in OpenSim by Utilizing SLoodle

The paper introduces and proposes a hybrid approach to computer supported collaborative learning. The approach suggests a combined use of the open source systems Moodle and OpenSim through the Sloodle module, in order to facilitate the fruitful execution of the collaborative learning techniques Jigsaw and Fishbowl, and examines their online transferability. In the concluding section, it is surmised that the successful combination of specific approaches and systems can surpass particular shortcomings inherent in their isolated use.

Collaborative virtual learning environments: design and evaluation

E-learning systems have gone through a radical change from the initial text-based environments to more stimulating multimedia systems. Such systems are Collaborative Virtual Environments, which could be used in order to support collaborative e-learning scenarios. The main aim of this paper is to aid educational designers in selecting, designing and evaluating three dimensional collaborative virtual environments in order to gain the pedagogical benefits of Computer Supported Collaborative Learning. Therefore, this paper initially discusses the potential of three dimensional networked virtual environments for supporting collaborative learning. Furthermore, based on a two-step platform selection process this paper (a) presents and compares three dimensional multi-user virtual environments for supporting collaborative learning and (b) validates the most promising solution against a set of design principles for educational virtual environments. According to these principles, an educational environment has been implemented on top of the selected platform in order to support collaborative e-learning scenarios. The design of this environment is also presented. In addition, this paper presents the results of three small scale studies carried out in a tertiary education department, to assess the educational environment. This environment has been evaluated based on a hybrid evaluation methodology for uncovering usability problems, collecting further requirements for additional functionality to support collaborative virtual learning environments, and determining the appropriateness of different kinds of learning scenarios.

Selecting and Evaluating a Learning Management System: A Moodle Evaluation Based on Instructors and Students

This paper presents the rationale behind the utilization of a Moodle Learning Management System for the facilitation of a blended learning approach in the Informatics department. The authors present and analyze the steps followed in order to replace the prior decentralized organizational structure of the courses, which consisted of a multitude of different and incompatible systems. The main goal was to implement a single system, which would be easy to operate, maintain, and update, and would cater to the variety of instructor and student needs. Furthermore, evaluation data of the new system is presented in detail. The analysis of the results serves to confirm the success of this department-wide migration.

Implementing Collaborative e-Learning Techniques in Collaborative Virtual Environments: The Case of Second Life

This paper reviews and compares the most promising collaborative virtual environment platforms, which have been used or proposed for supporting educational activities in terms of their potential to support collaborative e-learning. The most promising environment according to the results of this review is Second Life. Second Life is further examined by validating the platforms features, philosophy and policies against some basic design principles for collaborative virtual learning environments in order to better assess its design adequacy for online learning. Furthermore, this paper presents the features that we have implemented within the Second Life platform, in order to facilitate the jigsaw collaborative e-learning scenario. Finally, we present a case study concerning the evaluation of Second Life by undergraduate students in order to assess its potential to support collaborative e-learning techniques.

Selecting a Networked Virtual Environment Platform and the Design of a Collaborative e-Learning Environment

Our goal was to create a 3D virtual environment which could be used to carry out online lectures and which would offer the most popular features of current CVEs. This paper initially discusses the potential of 3D networked virtual environments for supporting collaborative learning and presents the assets of such systems. Furthermore, the paper reviews the features of five such software applications, through the comparison of the tools and services they offer. These include tools for supporting communication, sharing applications, organizing and coordinating the teaching process and for interacting with the virtual environment through an avatar. Based on that comparison, we justify our choice of platform and discuss design and implementation issues. Finally, future work regarding the assessment of the virtual environment is discussed.
