SUBJECT: Using peer review for student work
DATE: 2/97
 
 
Labbers,
I used to have students evaluate each others' paper drafts in a
zoology class at Elmhurst College. Unfortunately, the only comments made
by student reviewers were "good job" and "OK". I think it is MUCH wiser
to have the instructor 'review the reviewers' and grade them. That is the
current approach in the senior seminar course that we offer as a capstone
course. Students put some real effort into the review and often have good
advise to offer their colleagues.

I also have students evaluate each other's work in our senior seminar,
and the evaluation becomes a part of the evaluating student's grade but
not that of the one evaluated. I get a wide range of results, even
though I emphasize that the job of a reviewer is to help the author or
presenter improve the report. I provide examples of helpful reviews and
non-helpful ones, go over those with the students, and have them review
the first seminar without being graded.
 
Some then are very good at providing reviews that anyone should be able
to use for improvement. Others simply report "Great Job!!" and award
the maximum possible points for each criterion on the evaluation form,
even for work that is mediocre or worse. When I discuss these
evaluations with the students who wrote them, the usual reasons given
are, "I didn't want to hurt him," or, "I was trying to be encouraging."
 
But for the most part, for most students on both sides of the
evaluation, it has been a positive learning experience. Even those who
were very ineffective reviewers at first have learned from it.

GRADING PROPOSALS VS. FINAL REPORTS:
 
I have not tried having students review proposals for experiments. That
would probably be tougher for students to do that reviewing the final
product of the research (a paper or poster), since to critically evaluate
a proposal you would have to imagine or anticipate its flaws and
potential problems. When reviewing the results of a research project
students can evaluate the design with hindsight and with the benefit of
seeing how the experiment went, what interpretations and conclusions were
made (and how valid they are) and how effectively and convincingly the
results and conclusions were presented. Call it learning for one's
mistakes, and often that's how most real learning happens.
 
GRADING VS. REVIEWING:
 
I have had students grade each other's final reports (in journal article
format) or posters or lesson plans (teachers). I usually have the
assignment grade amount to 50% my grade and 50% the average of the
students' grades. They don't like it! They are really uncomfortable about
grading each other, though interestingly the education majors do this
better (are more critical, and give real A's, B's, and C's) than do my
science majors (all A's and a very few B's). For the most part I have
asked each student to assign a grade on a score sheet, with only a few
comments, and require that they grade (and thus, hopefully, read) each of
the other groups reports. My intention here is that the students are at
least exposed to all of the class's reports, and perhaps will learn to
recognize and learn from the best and the worst of other students' work.
With this kind of "review" assignment I have them review many posters,
but with only a modest depth of analysis on any individual review. I
figure that with enough students grading each poster/report any biased or
ridiculous grades will average themselves out, and I drop the highest and
lowest grades from the average to make the average more representative of
a class consensus.
 
A more thorough review assignment involves each student reviewing one or
a small number of reports, and writing a one-page critical review, which
itself is graded as a separate assignment. I use this to introduce to the
students the peer review process and the importance of critical analysis
and communications skills in science. I model this after the process we
go through to publish our scholarship in a scientific journal. Lab groups
submit their research report in journal article format, which is
forwarded to several peer reviewers. The reviewers must read and
critically review the manuscript, not to grade it but to make a
rcommendation as to whether it is suitable for publication. Criteria
include the quality of the writing, the clarity with which data is
presented, how well the conclusions are supported by the evidence
presented, whether alternative explanations exist, etc. The reviewers
must clearly present their analysis, and make concrete recommendations
for the publication of the manuscript and/or its improvement. My Adobe
Acrobat handout for the peer review process is available online at:
 
http://www.carlow.edu/~rhershberger/library/writing/Review.pdf
 
Each semester we get one instance of a report with unsupported or
incorrect conclusions, which go undetected by the reviewers (both lose
points). Another "teachable moment" happens when the writers have made a
correct conclusion, but because it was not presented in a clear,
understandable way (because of deficiencies in the students' writing),
the reviewers believe that the conclusions are invalid or unsupported.
The reviewers lose a few points if they really believe that a correct
conclusion is wrong (they should be able to arrive at the same correct
conclusion if they understand the experiment), but the writers also lose
points because, even though they are right, they failed to communicate
and convince their peers.
 
I use this assignment in my Genetics course (required of all bio majors),
and the experiment everyone is conducting and reviewing is a set of
inheritance problems generated by the BioQUEST Genetics Construction Kit.
Each experiment is different, but the concepts, experimental tools, and
research strategies are familiar to both the experimenters and the
reviewers, so the reviewers can't plead ignorance of the experimental
system.
 
OK, now get away from the computer and get back to grading ;-)

For what it's worth...
 
Helen Pigage alluded to non-critical peer reviews by
students of their classmates' work. I've had the same experience
when I've asked each student in my "writing enriched" Introductory
Ecology course to comment on a draft of another student's
literature-based review paper. (Each author subsequently
revises their work, based on comments from both the peer and
myself, before resubmitting it for a final grade.) Many
students (including even upper-level biology majors) seem
to be extremely reluctant to criticize each other AT ALL...
even when the reviews are anonymous.
 
Why? I have two guesses. First, substantive criticism requires
serious thought and time; it's a lot easier to be uncritically
positive. I suspect this is a large part of the story, especially
when it's true out there in "big science" too: as noted
in an commentary in _Nature_ from 30 January, many professionals
reviewing articles submitted for publication to journals pronounce
judgement just as blithely, with minimal constructive input. Doing
more is a lot of hard work ("intellectual heavy lifting").
 
The second guess has to do with the culture of our
current crop of college-age students. Might it be the case that
they've been poorly schooled in developing the ability to
make critical distinctions about what they read (and hear)...
and to have enough _confidence_ in their conclusions to
risk transmitting their ideas to others? Seems that way to me.
 
Student authors therefore may not benefit much from
comments they get from peer evaluators of their papers.
So, what's the value of having students write peer reviews?
 
Well, it never hurts to _try_ to get students to think critically
about written work. There is, though, another advantage:
when the students know that their work will be read
by their classmates, and not just by their professor, it helps
focus their attention on the communication task at hand. Instead of
taking for granted that the reader ("The Prof") will understand
a mass of undefined jargon and acronyms (those that the student
might hide behind, rather than displaying true (lack of)
comprehension of the material), the writer knows that they have to
explain carefully what they're trying to say...or their peer reviewer
won't be able to understand. Another advantage relates to the
revise-and-resubmit aspect: I suspect that some students
who might not be bothered at all about showing a professor a
crudely prepared first draft (if it's not graded) don't dare risk the
embarrassment of showing the same raw stuff to their classmates.
Wonderful thing, psychology!
 
I'd love to hear about related experiences or impressions of
others, especially those involved in efforts to help students
to learn how to write about biology (both learning-to-write
and writing-to-learn aspects).

I just had my microbiology students review each other's first lab report of
the semester. They traded reports, so they were working in pairs. The
review process was not graded -- I told them that they were to help each
other write better reports. Most of the class thought that it was a useful
exercise. Reasons given included "when you write something you can't always
tell what is wrong with it" and "I got good ideas from the paper I read."
Those who didn't find it useful wanted more time to revise after review.
Before they reviewed, I told them what I would be looking for when I graded
the reports, so this gave them one more opportunity to hear the criteria.
I'd like to write out a scoring rubric that they can use, which would
really help them internalize the grading criteria. Lab reports are due on
Monday, so we'll see if the quality was affected.

Richrad Hershberger wrote a lengthy explanation of the experience he has had
in having students grade each other's work. I will repeat (without the
detail I provided before) that I have students evaluate each other's work,
and that I include the evaluation in my assessment of the STUDENT DOING THE
evaluation. The evaluation enters into the EVALUATOR'S grade, but NOT the
evaluatee's.
 
I agree with all the positives in having students evaluate each other's work.
However, I WILL NOT assign, even as only a part of the the grade, a grade
arrived at by a student, or even use the student's comments in arriving at
the grade I assign. Several concerns cause my opposition to such a practice,
concerns that arise out of long experience with students.
1. Concerns about conflicts of interest on the part of students.
2. Concerns about incorporating student assessments into grades\
assigned when the students have little or no experience in
making such assessments.
3. Concern that I am responsible to the student, my collegues,
the administration and society for being the one to make the
judgement about a student's grade. For high achieving and low
achieving students (those who may get into professional school,
a top graduate school with support and so on, or those who mail
fail to graduate or fail to achieve a credential required for
a job) a great deal is riding on the grades. Admittedly, for
"average" students, the consequences may not be so drastic, but
all in all, students feel, rightly so, that we owe them an
absolutely fair evaluation and an absolutely fairly determined
grade.
4. If you think about the third concern, and don't feel that using
student comments or student assigned grades is ethically
questionable, perhaps the threat of legal action might be a
little stronger deterrent. Even if there is no legal concern
(and I'm certainly no lawyer), there might be the threat anyway.
 
I absolutely owe my students my own best professional judgement. Unless a
student is receiving payment from my university for grading, I will not
use student assigned grades as a part of the grade I assign. Think about
it. The student assigning the grade is also taking the class? That's too
much for me.

Hi, labbers:
I don't have much experience with students critiquing each others'
written work, but I do require my senior seminar students to critique
departmental seminars. Lo and behold! I find the same thing --
students are generally able to find something to say, but the vast
majority of them rate *all* speakers very highly (and much more
highly than many deserve).
 
In this case, students aren't critiquing other students -- so I don't
think there's any real concern about hurting someone's feelings.
And I really don't think it's lack of desire to work. Rather, I
think it's because they have so little basis for comparison (i.e., no
one has really taught them, by repeated example and discussion,
what makes really good seminar). So I wonder -- might that be a
contributing factor to the problem with written work?
 
Cheers,
Kerry

An approach that I have used that has produced fairly well thought out peer
reviews actually follows a typical essay assignment. It involves
distributing 5 of the student essays to the entire class. Each class member
is asked to rank the papers from "most effective" to least "effective" in
achieving the objectives of the assignment. They then must indicate what
would improve each of the papers so that it was as effective as the #1 paper.
This was not well received when I had student names on the papers the first
year. However, during the last two years the papers have been anonymous and
the students editorial suggestions have been useful and usually consistent.
 
I then distribute the pile of responses back to the original authors and meet
with them to discuss their response to the critiques and how they can
improve their paper.
 
A drawback is that only 5 papers get critiqued per assignment and only
those 5 authors get the benefit of the peer reviews. However, they get a lot
of reviews and usually see a consistency of response from all of their
classmates. I avoid the idea of grading in the students mind by stressing
the ranking of effectiveness rather than a grade. They then have to justify
the ranking by suggesting specific improvements to each of the lower
ranked papers. They are thus in a position where they have to make
concrete suggestions in order to justify there ranking. The students know I
read the critiques and that this has an impact on my perception of their
professional involvement in the course.
 
I believe a major benefit is that each student gets to see (must see) a lot
of other student writing during a term and must decide what is more
effective and what is less effective writing. Often students never see much
poor writing, other than there own (and perhaps some of mine). This gives
them, with each essay assignment, 5 examples of other students attempt at
that essay. They get to see examples of some fine student writing and some
poor writing all related to the same essay topic. By the end of the term all
of their writing has improved.
 
Thanks for the good ideas,

I am curious in the example from Al Williams if he has ever tried having
students review papers as groups so that instead of everyone reviewing
only five papers, each group reviews a different set of five. I did
something similar to this in an ecology course and it seemed to work well.
Do you discuss these as a class? That might be good reason to use only
five overall, but if the same sorts of problems occur in many papers, the
review of more papers might be enlightening and each student would benefit
from the review. The groups of papers should change each time, but groups
of students might not need to change.

Janice --
 
I thought I would reply to the group since I had received a few other
similar questions.
 
My use of having the entire class rank and edit 5 student papers with each
assignment has been an add-on to a number of content courses (Vertebrate
Physiology, Vertebrate Anatomy). We wish to facilitate writing within the
discipline through all of our courses. However, in these courses I do not
dedicate any extended in class time to direct discussion of writing and did
not want a time consuming addition to the already existing writing
component of the course.
 
There are usually 3-4 essay assignments per term. Thus 3-4 times a term a
group of 5 of the student essays are distributed (via E-Mail) to the entire
class. Everyone must rank the 5 and specifically suggest how each paper
could be improved to be as effective as the best in the group.
 
My goal is to create a situation where the student must read a variety of
student papers, all dealing with the same topic, that range in quality from
good to poor, and have the students begin to critically evaluate quality.
The ranking was a fairly simple way to force the students to not be
superficial. Once they had established a rank order they seem compelled to
justify it by suggesting needed improvement. As this is repeated through
the course they get much more effective at picking up a paper and with one
reading identifying a number of key areas where the paper can be
improved. About half way through the course I reinforce the idea that they
should be incorporating this same critical evaluation into reading their own
work, that having others review drafts of their writing will obviously
improve their writing, and that in the final analysis there are usually many
good ways to write on any topic and a far greater number of poor ways.
 
Many students have never seen a variety of essays all dealing with the same
topic and thus don't have an intuitive feeling for how simply changing the
organization, or choice of examples, or sequence of ideas, can radically
change the effectiveness of an essay.
 
I like the suggestion of having groups do this rather than individuals. The
discussion would be a much more effective learning situation. However, it
seems that it would also become a much larger assignment involving either
dedicated class time or the students would have to prepare in advance and
schedule meeting times for the group discussion and preparation of the
final reviews outside of class. In discussing this assignment with students
my impression is that currently, once they understand what they are to do,
it takes about 45 minutes to read the 5 essays, determine their opinion of
the rank order, and type up a specific list of suggested improvements for all
5 papers. That type of time commitment lets me consider it a fairly small
assignment that can be done any evening. I believe I will try the group
approach in one of the courses next year.
 
Another aspect of the assignment is that the entire set of class responses to
the essays is made available to the actual authors of the original essays.
They get a great deal of peer review of their work. After they have
digested about 25 sets of comments/suggestions on their essay I meet with
them and we plan a revision of their original essay. By the end of the
course everyone has had at least one of their essays reviewed by the entire
class. I think they are very aware that I am not the only audience for their
writing.
 
Finally, this has not been very time consuming addition to the course for
either myself or the students. I was interested in an approach that would
force more serious thinking about writing without my having to actually read
more student writing.
 
Thanks,
Al Williams

Well, I'm interested in "student writing assignments," but I'm not
interested in reading them. <head hanging in shame> I have 150-or-so
students, and my dedication just doesn't reach that far. For that reason,
I've been just skimming this thread, but I'm glad I took the time to read
all of your post. Perhaps by involving the students the way you suggest,
it's possible for them to have this valuable learning experience even with
a lazy professor like me!

You'd be amazed at how quickly reading and grading can go with a familiar
topic--one that you have devised and to which you have a clear expectation of
a correct answer. In the early stages of my intro. to bio. course, after I
have presented the concept of science as pure or applied, natural or social,
I ask: "Is medicine a natural or social science, and is it pure or applied?"
Students are directed to produce a one or two page essay. I can grade 50 of
these in less than an hour! It will also tell you a great deal about your
students. The ones who confuse "medicine the discipline" with "medicine the
pills that you take" need extra help and this is a good time and way to find
this out.
 
Another good one is: "Can social sciences be pure?" I have previously defined
"pure science" as science pursued for the sake of the knowledge alone.
Applied science, for our purposes, is science used to solve some
human-perceived problem. I define technology as pure (!!!) applied science,
just to make them laugh (Laughter is a good thing in a science classroom,
no?).
 
Later, after we have talked about biotic and abiotic factors in an ecosystem
and the students are reasonably well versed in the organic vs. inorganic
controversy, I ask: "Is the water, carbon dioxide, and oxygen which is inside
of cells biotic or abiotic?" "If biotic, how do they differ from the same
molecules in the air and water around the cells?" "If abiotic, how can it be
that they are vitally necessary for life?" I have a clear idea of the kind of
answer I am looking for here and can pick it up in seconds.
 
A word of caution. It is best to grade "easy" on these kinds of assignments.
Generally, I give at least an 80% award to any reasonable effort. These
assignments are meant to bolster the grade, not kill the students (that is
much too easy for professionals like us). Well written efforts get 90% and
when they hit it on the head (in my opinion, of course) they get a full point
award. I am usually dealing with anywhere from 5 to 20 points per assignment.
By showing them that they can get nearly full credit for a well constructed
argument regardless of the correctness of the answer you do them a truly
great favor.
 
I give less than 80% only for those papers in which the author has failed to
use the obvious resources at hand, such as the textbook, a good dictionary,
or the definitions which we have worked with previously in our class. Even
then I may stop at the 70% mark. The most difficult thing about this kind of
grading is to notice the really innovative answers--they can be easily
overlooked. I have learned a good bit from such responses (At least from the
ones which I have, in my haste to finish grading, noticed!).
 
Above all, respect your students and have fun! If you find teaching to be a
bore or drudgery, then get the hell out and let somebody else have a go at
it!
 
Speaking of hell, does anyone remember Hatlo's Inferno? It was a syndicated
cartoon feature in which a cartoonist named Jimmy Hatlo created cartoon
depictions of specially created scenarios in hell for especially irritating
people. I haven't seen it for years and have no idea what happened to Hatlo,
but I have a Hatloian inferno for teachers who hate students or who are bored
with teaching and continue to do it for the money and/or prestige. They are
forced to sit for all eternity while listening to an 18 year-old girl talk
incessantly about her friends and her make-up.

P.S. When we say that science is "natural" as opposed to "social", what do we
mean by "natural"?

A good point. Sometimes I think we're so concerned with our status as a
rigorous subject that we can be unreasonable and forget the level at which
our students are operating.

Just wanted to add a little to this. I give my upper level and graduate
students concept analysis writing projects. These involve them
considering some central question, read several pertinent articles then
put together a reasonable scientific argument relative to a stance on the
original question.
 
As I am trying not just to teaching them the content but also how to
think through it and how to express it scientifically, this turns into a
fairly significant project (they usually do 2 or 3 per semester). On the
due date, they turn them in. I read and critique (severely) then return
them for "fixing." They turn them in again. I read them again (MUCH
easier to do the second time) and sometimes give them back for further
fixes. I do not award a grade until the paper is A quality or they give up.
 
Interestingly, the 2nd and 3rd papers turn out much better on the initial
screening than the 1st was.
 
I explain a couple of things to my students in this process: 1) as
professional scientists we do not write, we rewrite. 2) I am doing this
to them because it causes them to focus on growth rather than just
turning something in and hoping for the best.
 
We have had some amazingly successful individuals come out of this
approach. Fellow professors have given me much positive feedback and the
students have taken the trouble to call, write, or come back for a visit
to let me know how much the method helped. For most of them it was the
first time a professor wouldn't allow them to get by with a low grade and
poor performance.
 
Best wishes,
Bill

Dear Biolabbers,
 
I can't believe some of the stuff I am reading on the discussion
group lately. Can anyone spell "grade inflation"?? What do you
think we are setting our students up for? It's setting them up
to get fired! It's not our fault that the high school system can't
put together a decent program of education that stresses the
development of a rigorous work ethic. But we shouldn't perpetuate
that kind of attitude at the college/university level. We
shouldn't be patting them on the back for just showing up for
an assignment. Grading easy - don't make me sick!! Everyone here
knows that the best learning experience they had as an undegrad
or a grad student involved working out a problem, spending whatever
amount of time it took to get the job done. Our current crop
of students don't have a clue about the relationship between work
and productivity. The buck has got to stop somewhere. Let's forget
about faculty evaluations for minute and remember that we are
here for the best interest of the students. I am getting out the
asbestos suit for the flames I'll get for expressing this opinion
but somebody has got to say something. When the average grade
is an A- then what is average??
