Assessing the Application of 3D Collaborative Interfaces within an Immersive Virtual University

Introduction

Recent years have seen an increase in the use of computers as a form of e-learning. The primary focus in this area has been on providing tools to deliver course material using web pages, while also providing techniques to manage both the material and users within such systems. These systems are often referred to as Learning Management Systems (LMSs) and predominantly support asynchronous interaction between their users. While the penetration of such approaches is vast and their popularity continues to grow, research indicates that courses which rely solely on these mainstream e-learning applications have a higher dropout rate than their face-to-face counterparts (Martinez, 2003). Studies indicate boredom, ennui and a lack of motivation are contributing factors to the high attrition rates within online courses (Serwatka, 2005). Research in this area is ongoing with techniques to resolve the problems of the lack stimulation and interaction being explored (Mowlds, Roche & Mangina, 2005; Sun & Cheng, 2007). One major concern with conventional e-learning techniques is the absence of mechanisms for instant communication. This leads to a lack of timely interaction between learner and instructor, hinders social interaction among learners and is one of the major drawbacks of standard online learning techniques. Ultimately, it has been shown that this absence of interaction and social connection with peers, and the tutor, can lead to feelings of isolation and loneliness for students (Kamel et al., 2005). Similarly the traditional approach relies on text-based web-pages which involve students reading large passages of text which they may find boring and unappealing (Anaraki, 2004). Figure 1 highlights the main issue with conventional LMSs.

Issues with existing e-learning techniques

Collaborating with peers is an important element of learning in the real world (Kitchen & McDougall, 1998; Vass, 2002). It teaches students about cooperation and teamwork. The asynchronous communication techniques provided by mainstream e-learning applications are not entirely suitable for organising group projects and consequently such tasks are generally absent from e-learning courses. Social interaction and the sense of a social presence among students are also important (Laister & Kober, 2002). Students often build friendships with their classmates in the real world. This interaction with others plays a key role in the personal development of students and their formation of social skills. The asynchronous communication methods offered within traditional e-learning applications do not permit a natural flow of conversation which hinders social interaction among students. Consequently they may feel they do not have a social presence within the learning environment or experience a sense of a community, both of which can lead students to withdraw from their course of study prematurely (Serwatka, 2005).
