What is Calibrated Peer ReviewTM?
Calibrated Peer ReviewTM (CPR) (more info) is a web-based writing and peer review tool free to instructors and their classes. Students write short essays on a given topic following guided questions to articulate their ideas and promote critical thinking. Students submit the essays online then read and assign a score to three "calibration" essays. After gaining practice reading for content and reviewing, students read and score three anonymous peer essays. At the end, the students go back and read and score their own essay.
The effectiveness and use of Calibrated Peer ReviewTM in introductory-level courses
Elizabeth Heise at Blinn College gave the same set of essay assignments to two introductory-level geoscience courses. One section was instructed to complete traditional writing assignments, while the other section utilized the electronic peer review program called Calibrated Peer ReviewTM.Heise found that the students' writing skills with the traditional writing assignments did not improve from one assignment to the next. However, the students that used an electronic peer review system showed improvement in their technical writing and critical thinking skills between two assignments.

Example CPR Assignment - Why Study Geology?
The goal of this assignment is to introduce students to the science of geology AND to the process of Calibrated Peer Review - ideal for a first writing assignment of the semester. It is a short assignment which points out the characteristics of geologists and the role of geology in our world. This assignment is available in the CPR library. A limited preview of the assignment is available in the CPR Assignment Library (more info) (instructors can view the full contents of the assignment library once they complete the free registration).
