Peer Review Process



The peer review is a process that accomplishes the goal of increasing student comprehension of material through increased students-student and student-instructor interactions. To assess the benefits of the peer review, students must attend class with two copies of their assignments. The first copy remains untouched as a sample of pre-peer review student work. Changes can be made to the second copy during and after the peer review process as errors are recognized.


The peer review is completed as follows:



Reflection from JKP (7-18-98):

Over the course of the program, the students demonstrated increased comprehension of organic chemistry. Although many factors contributed to this increased comprehension (extended exposure to material, classroom instruction, reading and practicing, etc.), I believe that a significant factor was the peer review process. At the beginning of the course, many of the formal peer review sheets did not include comments, although comments and corrections were made in class. This changed as the course progressed for two reasons: (1) extended exposure, and (2) time issues.

(1) More comments appeared on the peer review sheets as the students became more familiar with basic issues such as bonding and electron counts due to simply increased exposure to examples. It was easier for the students to review assignments such as acid/base reactions when they did not have to spend a lot of time making sure the electrons and charges were correct. This allowed more review of concepts such as which proton is the most acidic, rather than general issues.

(2) More comments also appeared due to time issues. The two peer reviews were very rushed because there was a lot of new material to introduce on those days. After these, the next three peer reviews remained relatively constant in duration (about 25 minutes each), yet comments made on the formal review sheets as well as correct changes made to assigments increased, indicating that (1) exposure to material was a significant factor in the students' learning.


Examples of Student Work

Included below are examples of student work which demonstrate progress over the course of the program. Examples are given of assignments which were good before the peer review and remained good after, bad before the peer review and became good after, and bad before the peer review and remained bad after.

The following table includes the graded work after the peer review process.

The assignments were graded based on the following criteria:

I chose to grade the assignments in this manner because I felt that doing so would give the assignments some validity (even though they did not actually count for a grade that would appear on a transcript) and because it would give the students an idea of how they were doing.

We have included the feedback as important because the students were inspired to complete the assignments and to really try to do well, despite the fact that this wasn't for a formal grade. The following table is a reminder of the value that iterate feedback has for students monitoring their progress.
