"Delivering Performance Feedback to Teachers" is an interactive and conversation-based training simulation that lets principals practice giving feedback to virtual teacher (avatars). I think the game is beyond helpful due to the fact as school leaders, it's hard to give a neutral feedback to the teachers from time to time, which may deter the leaders from giving it at all.
After having run across with this virtual reality platform while reading through the last week's article, I have been exploring it to see how I can facilitate it in my workplace. It's kinda Second Life application which might cause you to become virtual reality life addicts. Highly catchy, highly recommended :)
