The report for the Second Life Education New Zealand project and the virtual birthing unit has just been released - you can download the pdf from the SLENZ (now VLENZ) blog.
The report focuses on the design and development of the birth unit and touches on the students' experiences of piloting it for the first time. It is very interesting reading if you are thinking about carrying out a similar project to develop educational resources in Second Life.
What this report will not tell you is how effective the virtual birth unit is as a teaching tool, particularly in relation to learning outcomes. This is a project that is waiting to be done...hopefully by myself in the next few months.
Please let me know if you'd like to know more about the virtual birth unit and normal birth scenario in Second Life.
