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.

Homework, traditionally … For students to demonstrate mastery of
the subject. 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.

Major advantages Expertiza discourages plagiarism
Students are not doing the same work. Their work must go through multiple review
cycles Expertiza better utilizes scarce resources
Students do most of the reviewing. Instructor/TA spend less time grading.
With Expertiza, large classes are an advantage!

Why team assignments? Teamwork mimics the work environment Teaming skills are important to success Teams can tackle larger projects,
which diminishes the effort of integration
04/20/23 Gehringer, Rubric-based peer assessment of team projects, [email protected]
How does Expertiza support teams? All team members have access to a
common submission area. Any member can revise the submission.
Individuals review teams. This simplifies reviewing, and provides for more reviews.
Teammates assess each other’s contribution to the team. This score can be factored into the student’s
grade.
