2D VLEs vs 3D VLEs, a comparison of Adobe Connect and Second Life in an Educational Setting

My online graduate programs at the University of San Francisco makes use of two distinct, powerful VLEs, Virtual Learning Environments.  The first, Adobe Connect, is a two dimensional VLE that allows communication between instructors and students using audio and video and real time.  Additionally, the instructor may see the students desktop, text chat can be used, and surveys can be posted.  Communication can be synchronous or presentations can recorded for later use.  Adobe Connect's greatest strengths are it simple, straightforward interface and the low impact it has on computing resources.  The interface can be easily modified, resized and adjusted to suit the task at hand whether it is video conferencing with multiple participants, presenting a lecture using presentation software or even a basic audio chat.  Adobe Connect accomplishes all of these tasks with minimal system lag, using the smallest bandwidth possible while maintaining audio and video integrity.

Perhaps, the simplicity is also its weakness.  The interface may be seen as rudimentary and sterile by students who are used to video games, music videos and special effects laden television programs and films.  The 2D world of Adobe Connect may just be engaging or immersive enough for younger students who may have short attention spans.

Second Life, on the other hand, is a three dimensional VLE that seems perfectly designed to the younger generation of students.  The colorful complex graphics, the engaging experiences and the ability to move through space are its greatest strengths.  The simulation of 3D motion with one's personal avatar is immersive enough for many students to be almost indistinguishable from real life experiences.  That level of immersion is when learning, especially language learning can take place.

Although Second Life can be engaging, the initial learning curve is steep despite many teaching aids and orientation environments.  There is so much capability built into Second Life that avatars, motion, navigation, etc. can, at first, seem overwhelming.  Retention rates, often as a result of the learning curve and the significant load the environment places upon computing resources, are exponentially low.  Many first time visitors never return.  However, those who either through personal persistence or the guidance of a mentor, come back for subsequent visits are rewarded with an immersive experience that is both engaging and educational. 

For teachers, especially those teaching languages, being able to meet with students in an environment far removed from the traditional classroom, provides an environment in which student can lose their inhibitions and explore the world around them as well as their burgeoning language abilities.
