We have touched upon many new technologies in our class that open up new ways of modeling thinking, collecting and retrieving information, and sharing knowledge. I agree with my classmates who have already posted that second life is a unique, afforadable, and accessable way for students to interact with one another without losing a sense of creativity and personality. If we think of second life as a new virtual classroom as opposed to discussion boards or even back and forth email communication, Secondlife incorporates spacial interaction between users as well as offering new ways to communicate. I can definitely imagine a virtual classroom in second life, where every student is told to meet in a certain spot (like the isis oasis) and then the class could be taught through lecture or discussion, or traveling to different places. ( I can just imagine a group of 20 avatars flying together to visit an educational slurl).
As far as other technologies go, I really believe that wiki projects online are going to make an impact in the University. Collaboration in learning seems to be prominent here at Duke (from my experiences that is) through group projects, presentations, etc. Wiki's offer a new way for students to interact with each other and gain more insight into a variety of subjects.
After our discussions about the benefits of having a completely online learning experience vs. an in class learning experience, I do believe a happy medium can be reached between the two, to secure the best benefits of both spectrums. We do not want to lose all physical interaction, but the internet does offer a gigantic amount of useful tools for educating.
As for technology fads that wont last, I do agree with Aileen that I'm not a huge fan of the podcast phenomenon. I did enjoy making my own earlier in the semester, but listening to them (especially with my short attention span) can be brutal, and I don't know anyone who really commits to listening to podcasts on a regular basis.
I would also like to know the classes opinion on webcams, and if this device is here to stay. I know webcams used to be big for chatting with relatives/friends online, but I haven't seen one being used in a while. Its also interesting to think of the webcam in education, and if it provides a more personal vibe when interacting online.
