Participants in both groups then completed the physical world PCR practical individually in the laboratory. During the physical world practical the number of questions asked of staff and demonstrators by students in each group was recorded. After the real-world practical all participants completed the in-class quiz once again as a measure of overall learning gain.

Pre-, mid- and post-tests were used to examine the learning gains seen in the students at each stage of the teaching process. The learning gains of each group at the three stages of testing are illustrated in Figure 2. Using a mixed (or split-plot) ANOVA there were found to be no significant difference between the learning gains achieved by the SL and non-SL groups, with both groups achieving the same mean increase in test score between the pre and post tests. Interestingly however, there was a significant difference between the scores achieved by students in the SL and non-SL groups overall (p<0.001), with the initial average pre-test score of the SL group being significantly higher than the initial average pre-test score for the non-SL group. Quiz scores increased significantly across the study for students in both groups (p<0.001).

The number of questions asked by students during the physical world laboratory practical was recorded for the non-SL and SL groups. As can be seen in Figure 3, the non-SL group (Demonstration) asked significantly more questions (p<0.001) during the practical than the SL group. Furthermore, the staff supporting the practical sessions reported the SL group students to be more organised in their conduct during the class and appeared to take less time to complete the task.

Overall, satisfaction with the Virtual Lab was high. Ninety-two percent of respondents said they would use Second Life again and many had commented during the teaching session that they would like to see other experiments in the Virtual Lab. There were no significant differences in opinion between the sexes and between those who are re-sitting the module (11 students) and those that were not. Students who had already completed one Semester of the course joining the programme in October 2008 (21 students) found the in world instructions on how to complete the Virtual Lab experiment more useful than those (29 students) who started in Semester B, February 2009 (p<0.05).

A moderate negative correlation was found between age and overall satisfaction (r= -0.54, p<0.001). Younger students were generally more satisfied with Second Life than older students.

Those who had used Second Life before the study (16 out of 50 students) differed significantly in their expectation of in-world feedback whilst undertaking the Virtual PCR experiment from those who had no prior Second Life experience (p<0.05). Of the 16 students that had used SL before 6 students answered Q11 of the questionnaire (Table 1) with 3 or lower while only 4 students out of the 34 who had not used SL before answered Q11 in this way. Those who had used Second Life before thought that they had not received sufficient feedback during the experiment.

Finally, as students become active participants in virtual world classes, the student who is on “cruise control” is at risk. Students shift from being passive listeners to engaging in group interaction and activities and demonstrating that they understand the course content via the completion of projects, papers, labs, and case studies. Many classes that include case studies use role-play, putting learners in roles and contexts in which they explore the content and make decisions based on the forces and constraints placed on them. One example of a class role-play is shown in Figure 2, which depicts Ramapo’s immersive literature activity in which Suffern Middle School students enact the courtroom scene from John Steinbeck’s Of Mice and Men. The students’ exploration of the content benefits from this social learning environment.

In their “lessons learned” papers, the students noted that the virtual world classes enhanced their learning experience and their perceptions of self and gave them new skills to demonstrate their mastery of the course content. The sense of presence and the customization of their avatars were high on their list of priorities for learning and participating in virtual world classes.

Classes in virtual worlds offer opportunities for visualization, simulation, enhanced social networks, and shared learning experiences. Some people learn best by listening to the course content, others by seeing and visualizing the content in context, and the rest by using a hands-on approach to demonstrate course competencies. In virtual worlds, we can leverage a mix of content and activity to support all learners: auditory, visual, and kinesthetic. Virtual worlds support these different learning styles and give students opportunities to explore, discover, and express their understanding of the subject. Naturally, the tool’s capabilities do not guarantee a great learning experience. The success of a course depends on effective course design, delivery, and assessment. Course designers, instructors, and IT professionals are challenged to create stimulating content, deliver it reliably, and ensure a stable virtual world learning environment. Do the benefits outweigh the risks associated with venturing into a virtual world educational platform? For me, the virtual world is my preferred learning and teaching environment. And I am not alone. Over 400 universities and 4,500 educators participate on the Second Life Educators List (SLED).1 All of us are studying how to leverage the benefits of learning in a virtual world in order to assist our students in today’s educational frontiers.
