Should college students know more scientifically?
January 20, 2011
According to a
new study by researchers at Michigan State University, many college
students are in the dark about environmental basics. This includes
basic knowledge of the conservation of matter and of the carbon
cycle, and could be directly related to students’ understanding of
climate change.
The study
argues that these biological principles could better prepare
students to deal with important environmental issues such as global
climate change.
MSU professor
Charles Anderson is a teacher of education, and co-investigator on
the project.
Together with
lead researcher Laurel Hartley and several others, they studied the
science knowledge of 500 students from 13 U.S. colleges in courses
ranging from introductory biology to advanced ecology. They found
that the students were not quite at the level expected of
them.
The study found
that the students were faulty on basic scientific principles and
concepts, such as those that transform carbon. One of the most
fundamental principles is the conservation of matter, which states
that when something changes chemically or physically, the amount of
matter at the end of the process needs to equal the amount at the
beginning. This basically means that matter cannot simply
disappear.
For example,
students had trouble explaining weight loss. They relied on widely
held beliefs that weight is “burned off” or fat is “melted away.”
Instead, the fat molecules leave the body as carbon dioxide or
water primarily through breathing.
They also
attributed plant growth primarily to the soil, rather than the
carbon dioxide in the air.
Upon asking
several UNA students some of the same questions, the <a name=
“_GoBack”>issue can be seen here as well. It raises the
question of just how informed this generation is in the face of our
current climate crisis.
That is the
biggest problem: how students will be aware of
climate change and other environmental issues.
Dr. Richard
Statom, professor of geology at UNA, offers a slight
disagreement.
“For a
layman’s understanding of climate change,” argued Statom, “the nuts
and bolts of the carbon cycle are helpful, but not
essential.”
“Climate change
is much more political in nature. Trying to figure out whether our
own industry has caused higher carbon dioxide levels, and how that
can be managed, is more of an issue,” Statom added.
He agrees that
while students going into fields directly related to the
environment—those in ecology or biology for instance—should be well
versed in natural laws. The average student would do well to watch
his or her own carbon footprint.
