I have only taken this for a quick test drive so far, however I am already very excited about what I will be able to create with Voki. One of the things that appeals to me that I am intending to use next term is Voki Classroom and Voki Presenter aspects. Currently all my creating has been done by simply opening a free account. Which does allow you enough features to create some pretty fun Avatars. Of course to be able to access the extra features does cost money. However the cost is reasonable US$49.95 per year (AUS$65.00) which is not bad considering the feature you gain access to.
One of the exciting ways I am looking forward to using this tool is to get my students to create their own Avatars which will be used as part of an oral assessment task. It will be interesting to see how the students respond and what the quality of work will be from the more reluctant public speakers in the class. So far I have been creating some little scenes for my VCE students. They LOVE the avatars as they often pop up to remind them of something when they least expect it. Lots of fun!
