The following is excerpted from a longer
article that is posted on York's academic Integrity website <
www.yorku.ca/academicintegrity/sciencelabsabs.htm>. The full article not
only offers strategies to reduce academic dishonesty in the laboratories, but
it also outlines how one might develop guidelines for students on acceptable
practices for research, collaboration and reporting, and how to detect and
deal with breaches of academic honesty in this setting.
Fostering academic integrity within any course should include strategies to
avoid or reduce academic dishonesty, together with strategies for detecting
dishonesty and procedures for dealing with it. Below are a number of practical
strategies to help reduce plagiarism and data falsification in undergraduate
science laboratories. It is expected that not all strategies will work for all
courses and subject areas, but rather it is hoped that all instructors will
find at least some of the strategies helpful in designing or improving their
particular courses.
Approaches to Avoiding Problems inside the Laboratory
- If possible, have more laboratory exercises than needed for one year
(for example have 15–20 for a 12 laboratory course) and rotate them from
year to year.
- For some laboratories, have students write up the report in class. The
simplest way to use this approach is to have "answer sheets" the student
fill in. The sheets can have the general format of a formal report but
provide more structure, or they can simply be questions to answer, or tables
to complete. If you use this approach each year, be clear in your "policy"
to state that students cannot bring reports from previous years to class and
state clearly to what degree students may collaborate with one another
during this type of exercise.
Note: Paul Delaney [2] points out that these types of reports have the
bonus of encouraging students to work hard and concentrate during the
laboratory period and to always come prepared. The McGill website on
plagiarism [1] adds that these less formal reports usually cut down on
marking time for the TA.
- If you are using answer sheets that ask students to answer specific
questions, change some of the questions from year to year. Even small
changes are helpful.
- Within a given laboratory, change some of the parameters from year to
year. How easy it is to do so will vary with the laboratory or with the
level of the course, but with a little thought and creativity, it should be
possible for at least some laboratories. For example, if you are studying
the effect of hypertonic solutions on cells one year, make it hypotonic the
next year, or change the molarity of the solutions being used. Even small
changes can give students the sense that last year's results are not going to
be useful this year.
- For some laboratories, it may be possible to give each group a slightly
different experiment. Using the example in 4. above, each student could be
testing the effects of solutions with different molarities and/or different
solutes. In the case of experiments involving unknowns, give each group a
different unknown. In this way all results have the potential to be
different, and students may actually learn more by examining the data set
from the entire class.
- A nice approach for courses with 12 different laboratories is to have a
mix of in-class and out-of-class (sometimes called informal and formal)
reports. In such cases you can change which laboratories require
out-of-class or formal reports each year in order to decrease the use of
reports from previous years. If you are incorporating new or changed
laboratories, make sure they are the ones that require the out-of-class
report.
- For reports that are completed outside of class time, you might have
students sign and include a statement claiming that the report they are
handing in has been completed within the course guidelines for academic
integrity. [The McGill website [1] provides helpful suggestions for
preparing this type of statement.]
- Reduce the need to "policy" collaboration by allowing collaboration
between partners for some or all reports. [1] Obviously any intention to
vary levels of collaboration from one report to the next must be accompanied
by very clear guidelines.
- Have a portion of the laboratory grade come from laboratory quizzes and
exams, written in a non-collaborative setting.
- Oral reports and presentations are common in smaller more specialized
laboratory courses where larger projects are undertaken that require several
laboratory periods or even the entire course to complete. A thesis course is
an obvious example. However, it might be possible to incorporate oral
reporting or interviews into more laboratory courses [1,4]. An oral report
would require the student to discuss and justify his/her data and
interpretation, making it more difficult to hide dishonesty. Harris [4]
suggests asking specific questions about the written work, such as "What
exactly do you mean here by...?"
A similar useful technique would be a post-report interview or even a
written report or "meta-learning essay" where students are asked the
following types of questions:
- What problems did you encounter as you completed your experiments, and
how did you solve them?
- How do you feel these difficulties affected your results?
- Were your results what you expected? Why or why not?
- What have you learned about science and about how scientific
information is gathered as the result of this work?
- What future experiments would you perform in order to extend or
improve your data?
- What were the general conclusions you were able to draw from your
data?
- Reduce "hand-me-down" laboratory reports from previous years by
collecting and destroying used laboratory books at the end of the year [3]
and by returning reports directly to students in the laboratory rather than
setting them outside someone's door and therefore open to theft [1].
- Paul Delaney [2] emphasizes the important role of the TA in any effort
to ensure that academic integrity is maintained in the laboratory. TAs must
have a strong presence in the undergraduate laboratory, visiting each
student group regularly, interacting with them and forging a positive
relationship with each student. They should be looking at their data, asking
students if they have any questions, if they understand the data that they
are gathering. Students who know that their TA is aware of their data and
their progress are less likely to feel that they can successfully "fool" the
TA with a dishonest write-up. Students who respect their TA and are enjoying
their laboratory experience are also less likely to want to try.
Suggestions to Decrease Falsification of Data:
- Put less emphasis on the importance of obtaining expected or "correct"
and more emphasis on a student's liability to interpret and understand
whatever results they obtain. Emphasize that students will not be penalized
by presenting aberrant data, if the data are properly reported and if they
include a careful discussion about why the results may be aberrant/abnormal.
Reflect this change in the marking scheme and make it available to students.
- Give marks for good laboratory practice, for following procedures and
carefully recording results, not just for getting "good" results.
- Have a policy that requires students to obtain the TA's signature on all
pages of their original laboratory notes and data, and to submit those notes
with their laboratory report. TAs, in turn, should keep careful records of
attendance and of whose laboratory notes they have signed, in order to
prevent forgeries or other problems.
- Have students write all of their original laboratory observations in a
hard-cover laboratory book with numbered pages. TAs can then initial the
relevant pages and make note of the page numbers for each student, in case
they see something suspicious when marking. Laboratory books would have to
be submitted with laboratory reports.
- In courses where the integrity of the primary data is of great
importance, laboratory books are available that create carbon copies of each
page. The carbon copy may then be ripped out and handed to the TA before the
student leaves the class.
