- 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.
