Voki is a tool that creates a speaking avatar to use for assessment purposes, to add to blog, etc.
Some Ideas for Using Voki:
Give an Overview of a Module - Prepare students for what to expect in the coming module/ lesson
Explain Instructions to Students - This is the exercise we will be doing today and this is how you do it
Remind students of upcoming work in a fun way
Vary the voice of traditional speeches so as to present it in a new way - Lincoln's Gettysburg
Read essays - Have students speak their essays through the avatar for revision purposes
Have students write a summary of the chapter they read for homework and then have the avatar read back the summary. Share it with others to assess their summary skills.
