Dr. Gehringer gave this talk at the Purdue University in April 2009. It was about Expertiza with regards to Peer Review and Social Networking for Co-Producing Learning Objects
Expertiza: Rubric-Based Peer Assessment of Team Projects
From Class Project to Open Source: Packaging for Outside Development
Some of the future enhancements in mind for the Expertiza project are:
1. Assigning extra credit for student doing voluntary quality reviews.
2. Reputation based grading, based on the quality of review a student gives.
For example this could be based on the number of high scores that the reviewer gives and then also based on the metareview.
3. Implementing a method for doing automatic metareview, meaning that the program calculates the metareview based on some keywords and on the content of review.
