Voki

I really enjoy the Voki application!  It is really easy to use (when the computer is working) and it lets my creative side go!  In the high school classroom, Voki would be a great way to create an anonymous discussion.  Each student could create their own avatar and post responses to questions that might engender ribbing from their classmates if they knew who the person was.  The site also prevents many lewd uses that teenagers would definitely find simply due to the fact that it is not completely freestyle in the character creation.  There are set parameters that are present in the software itself.  For example, although the character may not have visible clothing, only the head and upper shoulders are visible.  This would prevent actual nude characters from parading around in the classroom.  The biggest issue that I see with Voki is the fact that the students can write anything that they want their avatar to say.  This is where an in depth explanation of what will be acceptable for the assignment must be made completely clear before the first word is written.
