10/15/2015Gehringer, Rubric-based peer assessment of team projects, Introduction  Expertiza began as a peer-review system for co-production of course resources.  Building resources through electronic peer review gets students working together to improve others’ learning experiences, helps them learn, by performing tasks that are similar to real-world responsibilities, gives them experience in writing their ideas up for an audience of their peers, allows each cohort to “stand on the shoulders” of students in earlier classes.

Every student does the same thing— redundant effort. Work is graded and thrown away, never benefiting anyone but the student who did it.  In Expertiza, students (or teams) sign up for different work  Now the best work can be reused, to help others learn.
