Enriching Classes
Using the News Media

Introduction
Grey and Mathre (1) suggested the use of media articles related
to plant pathology to increase student appreciation for the importance
of plant diseases, to improve their communication skills, and
to practice vocabulary related to plant pathology. I have
applied this idea in a core biology course at Marquette University
that uses plant pathology and agriculture to illustrate important
aspects of general biology. This university has no agriculture
program, so students are primarily from the Colleges of Arts and
Sciences, Communication, and Business.
The course is scheduled to meet in two 75-minute sessions. Rather
than lecture for the entire time, short lectures are interspersed
with group discussions, simple hands-on laboratory exercises,
and presentations by the students. Students choose their topics
subject to approval by the instructor. Each student presents once
during the semester. They sign up for a presentation day during
the first week of classes. The assignment consists of a 5-10 minute
presentation to the class as well as a written report. Presentations
do not begin until the third or fourth week of the semester so
students have some background and time to prepare. We had 2-3
presentations per lecture period with a class of about 50 students.
After trying this several times, certain aspects of the exercise
have made it more effective both for the individual student and
for the class as a whole.
Resources for reports
It is important to provide appropriate resources for students.
In this assignment, students are given a choice of presenting
on a specific plant disease that has not been discussed in detail
in the class (“disease of the week”) or a topic related
to plant pathology (“media report”). Good resource
sites are the APSnet Feature Articles (http://www.apsnet.org/online/feature/),
the International Society for Infectious diseases (www.promedmail.org),
the US Phytosanitary Alert System (www.pestalert.org), and Science
News Magazine (www.sciencenews.org).
The APSnet Education Center (www.apsnet.org/education)
disease lessons can be understood even by students with little
background in plant pathology. As the semester progressed, I watched
for appropriate articles and brought copies to class. I would
describe the subject in a sentence or two and offer it to anyone
who wanted it. Science articles from local newspapers, the news
sections of the journals Science or Nature,
and articles from other publications related to plant pathology,
agriculture, biodiversity, global warming, and current health
issues were used.
Requirements that enhance the exercise
Certain requirements of the assignment made it more effective.
They included:
For media reports:
- Briefly summarize the content for the class.
- Explain how the subject relates to the course and why this
particular subject was of interest to you- and why it should
be of interest to students in this class.
[Comment: This requirement resulted in some very interesting
comments from the students.]
- Analyze the report for bias and accuracy. Do not assume that
because someone is a “scientist” that they are unbiased.
An unbiased article may take a side on an issue, but will include
a fair appraisal of both sides of the issue.
[Comment: In the past, students would write that someone was
a scientist and therefore
unbiased. One student reported on a local version of an article
on the use of sauerkraut for
avian flu that originated with the Associated Press. He found
the original AP article online and
detected some bias in the local version which was promoting local
sauerkraut producers.]
- List questions and concerns that you have related to the information.
[Comment: This last requirement was particularly successful because
it made students think
about what was missing in the information or what they wanted
to understand better. They
were quite good at detecting missing relevant information.]
For disease reports:
Explain why the disease was of interest to you and why it should
be of interest to students in this class. Try to determine:
- the significance of the disease
- the type of pathogen, its name, and some details about its
biology
- what kinds of plants are affected
- where the disease is a problem
- what can be done to manage or prevent the disease.
List any questions that come to mind as you try to find information
about the disease.
Assessment
Students were given the following assessment guidelines so they
would be sure to include all required sections:
Presentation to class: clarity, accuracy, reason
for interest |
10 pts. |
Written summary: |
5 pts. |
|
Appropriate information source |
5 pts. |
|
Accurate information about subject
(includes grammar, spelling) |
5 pts. |
|
Questions listed that were not answered by source |
5 pts. |
|
Analysis of accuracy and/or bias of information |
5 pts. |
Total |
30 pts. |
Conclusions
This exercise benefits both the individual student and the class
as a whole. Students heard, at least briefly, about many topics
that were not included in the standard course content. The students
chose topics that they thought were interesting, and the presentations
were short summaries, so the listeners learned a lot in a few
minutes. Individual students were quite surprised that there were
science articles in various print and online media that were actually
interesting to them, that they could understand, and that they
could evaluate for accuracy and bias. Many were surprised to find
inaccuracies in media reports and that they could identify them.
One student reported on the Nobel Prize in 2005 for proving that
the bacterium, Helicobacter pylori, is the causal agent
of stomach ulcers. Barry Marshall had actually consumed a quantity
of this bacterium to prove pathogenicity and fulfill Koch’s
postulates (a topic in the course). In his presentation, the student
explained that he had to know what such a person looked like,
so he used the Internet to find a photograph of Dr. Marshall that
he passed around the class. To this student, a scientist had become
a real person whose life he could imagine.
