Peer grades from a course I recently took (and completed) on Coursera.org - does peer grading scale and could it be used in the assessment of physicians? In my course, the mean rating was used to create a score, using statistical methods, however, ratings can be tuned for greater accuracy. See http://tedeytan.com for blog post about this.

Evaluation/feedback on the above work
Note: this section can only be filled out during the evaluation phase.
Description of area or region:
Needs Improvement: Description of area missing, or unclear to the
reader/viewer
Meets Expectations: Area or region clearly identified. Link to larger regional
or global context present but doesn’t enrich the example. May simply give
geography
Exceptional: Area or region clearly described and placed in a larger regional
or global context. Links to region or globe add relevant information and he

3. Score from your peers: 4
Area or Region: What feedback might you give to the author of the project in
this area?
peer 1 → Very clearly identified location both in the text with a map and its
significance i.e. Washington DC, the national capital of the USA
peer 2 → The introduction to the area and the subject matter was
excellent..........and for a European reader it cleared up my lifelong query
about which state Washington was in......none!
Main Point or Claim:
Needs Improvement: Main Point or Claim missing, or vague enough that the
reader/viewer is unsure of the main point or claim.
Meets Expectations: Main point or claim present. Reader/viewer may not be
able to easily restate the main point themselves.
Exceptional: Clear and concise main point or claim. Reader/viewer can easily
identify and articulate the main point or claim.
Score from your peers: 3.5
Main Point: What feedback might you give to the author of the project in this
area?
peer 1 → The main point regarding renewable energy and its impact on
climate change is outlined quite clearly.
peer 2 → The report fully met expectations in its development of it main
theme of RECs as a recent market mechanism designed to encourage the
consumption of electricity from renewable sources

4. Evidence:
Needs Improvement: Evidence missing, or, if present, appears unrelated to
main point, or does not support main point
Meets Expectations: Scientific evidence relevant to the main point or claim
presented. May not be quite thoroughly explained.
Exceptional: Scientific evidence clearly explained; evidence presented clearly
supports main point or claim
Score from your peers: 3.5
Evidence: What feedback might you give to the author of the project in this
area?
peer 1 → Very good use of detailed evidence and how the REC system
works in Washington and the part it plays in the mitigation of CO2. Perhaps
a little too much detail for the definitions but still very useful information
peer 2 → Again the report was fully acceptable in providing evidence and
information about Washington DC and its deployment of this well described
market mechanism. I would really have liked to hear about the extent to
which individual consumers were actually buying into the scheme given the
20% premium over conventional electricity. Moreover I would have liked to
hear how DC coped with criticism from cc deniers or anti tax lobbyists who
would object to increased local taxes to fund as they would claim higher
than necessary city electricity costs
Presentation:
Needs Improvement: Confusing or difficult to understand
Meets Expectations: Organized logically, easy to understand
Exceptional: Organized logically, easy to understand, engaging and creative

5. Score from your peers: 4
Presentation: What feedback might you give to the author of the project in
this area?
peer 1 → Generally quite easy to follow; there was a very good discussion
of the benefits and the barriers regarding renewable energy in the latter
part of the essay.
peer 2 → This report was very well presented with good referencing and
excellent use of diagrams
peer 3 → Very good presentation
Overall evaluation/feedback
Note: this section can only be filled out during the evaluation phase.
Please write here any other comments, feedback, encouragement, etc. that you feel
might be helpful to the author of this work.
peer 1 → Overall a good and informative essay which certainly helped me
understand much better the system of renewable energy purchasing in
Washington DC. I was very interested in your final comments on the possibility of
a carbon tax in DC and it will certainly be an interesting debate to follow.
peer 2 → I enjoyed reading this well presented report on a market mechanism
being developed for cc mitigation in the USA which is being enthusiastically
adopted by the nation's capital city
peer 4 → Very nice. Easy to read and follow.
