Good
Science Results in Understanding and Action
By Robert Yager, Ph.D.
Too
many people think science in schools is an academic course
where content is included only in textbooks, where workbooks,
lab outlines, and frequent quizzes and tests are designed
to see what was learned—or really just remembered.
But science is so much more. It is wondering, questioning,
and thinking about the universe and the world where we humans
find ourselves. This is something everyone does—often
without thinking it is science. And, it doesn’t have
to be just science. It could result in many other human endeavors
like art, music, and religious reflections—or nothing
at all. To be science, however, the questions must move to
deeper thinking, especially related to proposing answers and
explanations.
This curiosity and making sense about things around us is
what people other than scientists do, too. The unique part
of science is the necessity of questioning more about the
“personally constructed” explanations by taking
on the challenge of collecting evidence to validate them.
But science, unlike other human disciplines, is a social enterprise.
The evidence presented to validate explanations must be accepted
by others—unlike musicians, artists, and religious leaders
where there is no requirement that others must agree with
the accuracy of the interpretations. To be science, explanations
must stand to the scrutinizing of others, especially leaders
who have advanced explanations and who are considered experts
in given fields.
Education can be a science, but it is far more often like
art and religion, disciplines where all are to see the beauty
and believe what others have proclaimed or envisioned. To
be science, evidence must be massed for others to scrutinize
and decide if it is adequate to accept and internalize.
Good science results in understanding and action—actions
that result in community benefits. There are hundreds of stories
of such science teaching, where the context is more important
than the content identified as information to present—to
see who accepts, repeats, and remembers it.
One of my favorites was a chemistry teacher in Denison, Iowa,
who agreed to teach an applied course to a group of non-college
types (mostly would-be hair dressers). He turned the class
over to students for ideas of what to study and how to manage
the course. After some discussion, the group zeroed in on
the ozone.
The teacher was surprised that the students were even aware
of the word, but gave it a try. The class never got off ozone.
Almost every part of the standard text was useful when students
wondered about such terms as pH, acid, molecule, reactions,
atom solution, even the periodic table.
The students went as concerned citizens and experts to elementary
school classrooms, service clubs, scouts, and other groups
to get them involved with problem resolutions. They even got
the mayor to declare ozone Depletion Day in Denison.
The study ended with the college-prep students asking why
the applied group got to have so much fun and attract attention
while they worried about the next test.
Too often science is seen as only useful as K-through-Ph.D.-level
academic preparation. We need to remember that science instruction
is more interesting to students when there are real world
contexts that provide a need to know.
Too often typical science classrooms are places where too
much time is spent with textbooks, and too little time is
spent dealing with real and community-based issues. Good science
is connecting content to personal, local, and current context.
Robert Yager is
a professor emeritus of Science Education. His contributions
to science teaching manifest in nearly every science
classroom across the United States and many throughout
the world.
“Many of the hundreds of graduate students he
has mentored have ascended to advance science education
policy in almost every state, as well as in Asia, Europe,
South America, Africa, Australia, and Indonesia,”
says Jeff Weld (BS ’83/MS ’94/ PhD ‘98).
“He has permanently altered the landscape of science
education.”
Throughout Yager’s 48-year career, he has helped
lead the College’s Science Education Program into
one of the largest and most productive in the world
in terms of graduate students, model programs, funded
projects, and national and international activities.
