Making
Sure Science Skills Don't Rust
Penn Tests New Science Literacy Assessment Tool and Measures
the Impact of a New General Education Program
Although calls for improved assessment mechanisms and greater
accountability within higher education are nothing new, the
media have recently turned the public's attention to assessment
debates in higher education. According to a recent article
in The New York Times, "[I]t is no longer enough
for a university to say that it accepts only students with
high SAT scores; those scores say nothing about what students
learn once they're in."
Many colleges and universities,
of course, have been quietly retooling their curricula and
finding better ways to assess what students are actually learning
in college. The University of Pennsylvania (Penn) is testing
the effectiveness of their curriculum changes in a variety
of ways. One way is to test the level of students' science
literacy.
"We wanted to test science
literacy coming in and going out," says Ingrid Waldron,
professor of biology and member of the Pilot Curriculum Evaluation
Committee at Penn. At a school where many students arrive
with AP credits through which they "test out" of
core science courses, the survey is a way to measure the science
knowledge and understanding the students bring with them,
and what happens to that core of science literacy during their
college careers. Adds Waldron: "A lot of what's out there
assessment-wise is high school level; we were trying to get
at reasoning ability and statistical concepts—in addition
to basic knowledge."
With the new science literacy survey,
Penn also seeks to compare the science literacy of students
in a new pilot curriculum and those enrolled in their more
traditional curriculum. Two hundred students were randomly
selected to participate in the new pilot program for the College
of Arts and Sciences instituted in 2000. Students enrolled
in the pilot program work closely with an advisor to design
a course of study that is developed from a more compact but
more carefully focused general education experience. In place
of traditional introductory courses in a discipline that often
serve also as general education courses, pilot students take
newly created, cross-disciplinary general education courses,
such as "Quantum Theory and Its Philosophical Implications,"
taught by faculty from both the chemistry and philosophy departments.
Penn's science survey, administered
during orientation, is brief, requiring about twenty minutes
to complete twenty-three multiple-choice questions to test
basic science skills. The test also includes some general
information questions in order to categorize the respondents.
The results are compared for students in three groups: those
who are part of the new "Pilot Curriculum," students
who applied for the pilot program but were randomly selected
to be in the standard curriculum, and all other students.
When the test was first administered to all freshmen in September
2001, the school received usable surveys from 83 percent of
the students. On average, the students gave correct answers
for 55 percent of the science literacy items on which they
were tested. The creators of the survey look forward to testing
the same class during their junior year spring semester in
order to compare the progress of the students in the pilot
curriculum with the other students.
So now that we know how literate
the students are, how successful is the survey itself? "So
far, so good," is Kent Peterman's analysis of the survey's
success. Peterman serves as the director for Academic Affairs
of the College of Arts and Sciences and as member of Penn's
Committee on Undergraduate Education as well as a member of
the Pilot Curriculum Committee. Coming up with the best college-level
questions was not easy. According to Peterman, "We asked
items of appropriate difficulty. They didn't all ace it and
they didn't all bomb out, either." The hope is that the
survey will be "sensitive enough to detect small differences"
when the tool is administered to the same group of students
in their junior year. In addition, Penn found that scores
on the science survey correlated with the total number of
AP and college-level science and math courses that incoming
students took in high school. In short, the more such classes
students took, the higher their scores.
"For science majors, we don't
expect to find a big difference between the levels of science
literacy for students in the pilot curriculum versus our traditional
curriculum," according to Waldron. It is the non-science
majors they are watching to see if the two curricula promote
different levels of science literacy. "We are particularly
interested to see if the non-science majors graduate with
increased science literacy."
