Techniques for grading student performance in a simulation In most cases, professors need to grade the performance of a student in a simulation for the experience to be considered official. While ultimately this grading is probably just as arbitrary as grading a paper, at least grading a paper has the benefit of history on its side.

Write a paper about the experience in the simulation.

Keep a journal during the experience.

This study examines students’ reactions to the virtual biosciences laboratory developed in Second Life® (SL) at the University of East London. Final year undergraduates and masters students studying biotechnology took part in a trial of a virtual Polymerase Chain Reaction (PCR) experiment in Second Life and evaluated their experience by anonymous questionnaire. Learning gains were measured at various points during the study using pre- and post-tests, and interaction with demonstrators was monitored and compared during the real life (RL) practical. Both groups showed a significant increase in learning gain over the pre- and post-tests, although no difference in gains between the two groups was detected. However, students who conducted the PCR experiment in SL required significantly less demonstrator assistance during the subsequent RL practical. The SL practical was well received by students, with 92% of participants reporting that they would like to use the system again and many requesting other experiments to be made available in this manner in the future.

The aim of this study was to determine whether conducting the PCR experiment in the virtual world of Second Life produced similar learning gains to those observed in the physical world laboratory and to see if working in the Virtual Lab enhanced students understanding of the experiment. The student perceptions of the Virtual Lab as a teaching mechanism and the perceived impact on their learning was examined through questionnaires.

The SL group completed a pre(virtual) Lab quiz and then individually registered for Second Life to create an avatar under instructor supervision. Each student completed some orientation exercises on UEL Island to become adequately skilled in using the Second Life environment (e.g. flying, putting on clothing etc.). The student avatars then met in the Virtual Lab to perform the PCR experiment. This was initially demonstrated by a member of staff before each student completed the virtual experiment themselves. Throughout this teaching session the students received face to face and virtual communication from their instructor.
