Davidson and Gary McKinney Western Washington University
June 2001 WHAT
IS QUANTITATIVE REASONING? In
1997, the Washington State Legislature directed the Higher Education Coordinating
Board (HEC Board) to implement a budget-based accountability system. From this
directive, four assessment initiatives were developed. Two of these - writing
and critical thinking - are familiar concepts to most educators. Two others -
information technology literacy and quantitative reasoning - may be relatively
new concepts, or at least relatively new terminologies. The May, 2000, Dialogue
(Issue No. 6) presented an overview of information technology literacy. In this
issue, an overview of quantitative reasoning will be presented. Often,
quantitative reasoning (QR) is assumed to be synonymous with mathematics, and,
indeed, the two are inextricably linked. Yet there are differences, one of which
is that while mathematics is primarily a discipline, QR is a skill, one with practical
applications. A mathematician might take joy in abstraction, but the well-educated
citizen can apply QR skills to daily contexts: for instance, understanding the
power of compound interest or the uses and abuses of percentages; using fundamental
statistical analysis to gauge the accuracy of a statistical study; or applying
the principles of logic and rhetoric to real world arguments. Moreover,
while mathematics is often exclusive, frequently with a language of its own, QR
is inclusive, its language plain and everyday. In our information-rich - some
might say information-overloaded - society, QR skills are especially important.
We may no longer need to perform quantitative calculations by hand, but we do
need to interpret them and judge their accuracy. Few people are trained to work
with complex mathematical concepts, but all educated citizens should be able to
understand mathematics well enough to develop informed opinions about quantitative
concepts. To
illustrate the point, here are some test questions taken from a freshman Quantitative
Reasoning Study Packet at Wellesley College. Answering them requires quantitative
skills that most educators would agree all educated citizens should possess.1
- Officials
estimate that 320,000 Boston-area party-goers attended the 1995 Independence Day
celebration on the banks of the Charles River. They also estimate that the party-goers
left behind 40 tons of garbage. Given that a ton equals 2,000 pounds, how many
pounds of garbage did the average party-goer leave behind?
- One year ago,
a person invested $6,000 in a certain stock. Today, the value of the investment
has risen to $7,200. If, instead, the person had invested $15,000 one year ago
instead of $6,000, what would the investment's value be today? (Assume that the
investment would increase by the same proportion.)
- According to the Cable
News Network (CNN), the number of injured in-line skaters (or "roller-bladers")
was 184% larger in 1994 than it was in 1993. Did the number of injured skaters
almost double, almost triple, or more than triple?
[top] WHY
IS QUANTITATIVE REASONING IMPORTANT TO ASSESS?QR
is a state-mandated accountability measureWhile
arguably not the most important reason to address QR as a component of a complete
education, it is one of four state-mandated student learning outcomes. (As mentioned,
writing, critical thinking, and information technological literacy are the others.)
Western Washington University is leading the state effort in developing an assessment
of student learning in quantitative reasoning. We will be developing a plan for
assessing QR on our campus and will provide a progress report to the Higher Education
Coordinating Board later this year. QR
is a student learning outcome
For most educators the more important reason to assess QR is that in order
to become educated citizens students should graduate from college with some level
of competence in quantitative reasoning. "For students in non-quantitative
majors, the appropriate demand is that QR instruction act as a basic element of
the 'liberal arts' curriculum; that it prepare graduates to function well as citizens
in modern society. Many students do not learn sophisticated math skills, but all
should be able to use simple math tools to reason - to understand, interpret,
critique, debunk, challenge, explicate, and draw conclusions. In short, college
graduates should be able to evaluate the crush of quantitative data modern life
throws at all literate citizens."2
[top] WHAT
SHOULD A BASIC COMPETENCY IN QR INCLUDE?According
to the Mathematical Association of America (MAA)3 , the following quantitative
literacy (or QR) requirements should be established for all students who receive
a bachelor's degree: - Interpret
mathematical models such as formulas, graphs, table, and schematics, and draw
inferences from them.
- Represent
mathematical information symbolically, visually, numerically, and verbally.
- Use
arithmetical, algebraic, geometric, and statistical methods to solve problems.
- Estimate
and check answers to mathematical problems in order to determine reasonableness,
identify alternatives, and select optimal results.
- Recognize
that mathematical and statistical methods have limits.
Another
example of what QR competency might look like is found in Wellesley College's
"Quantitative Reasoning Requirement". At Wellesley, all freshmen are
required to take a QR placement test. If they don't meet minimum standards, they
must enroll in QR 140, a course that brings them up to competency. Once they have
completed QR 140 (of if they have already passed the QR placement test) students
must, at some point in their academic career, take a QR overlay course, designed
to "engage students in the analysis and interpretation of data in a scientific
or social context."4 The overlay course is intended to provide students with
a basic understanding of important ways that numerical data are used in problem
solving. Overlay courses are offered in the humanities, sciences, and social sciences.
They have five basic goals (note that these goals echo the Quantitative Literacy
requirements established by the MAA). - LITERACY:
Topics and depth of coverage enough so that students have the knowledge they need
to function in real-life situations involving quantitative data.
- AUTHENTICITY:
Students use authentic numerical data whenever possible. The experience should
arise naturally from the context of the course.
- APPLICABILITY:
Examples should be adequate to convince students that the methods of analysis
they learn are of general applicability and usefulness.
- UNDERSTANDING:
It is important that student learning go beyond rote application. They should
be able to recognize when they can apply what they have learned in the future.
- PRACTICALITY:
Breadth and depth of topics should be consistent with reasonable expectations
of students when data analysis is only part of a course requirement.
[top] WHAT
ABOUT A MINIMUM QR COMPETENCE AT COLLEGE ENTRANCE? Just
as we already use test scores to establish the abilities of in-coming students
- for example, from the SAT and Math Placement Test - we should be taking a measure
of students' QR abilities. As mentioned earlier, the connection between mathematics
and QR is close, yet also different - in all likelihood, different enough to warrant
taking stock. An additional test, however, does not necessarily mean subjecting
students to more tests; a slight remolding of the existing testing framework would
also work. Students anticipating they will major in science or mathematics could
continue to take the Math Placement Test (MPT); students anticipating they will
major in non-science or mathematics could take a Quantitative Reasoning Test (QRT). Alternatively,
all students, other than those excepted under existing guidelines, could take
a hybrid test that included elements of the existing MPT, plus additional QR-related
questions. Regardless of the direction decided upon, new test questions - or possibly
an entirely new test - would need to be developed.5 This logistical concern would
need to be factored into any changes to the current system. Most importantly,
any revamped, or entirely brand-new tests would need to reflect the anticipated
curricular changes. [top] IMPACT
OF A QR TEST ON CURRENT SYSTEM Logistically,
the idea of two tests - MPT and QRT - would create a fork: one leading to mathematics-intensive
courses and/or majors, the other leading to less mathematics-intensive courses
and majors. In circumstances where a student took the QRT, then later decided
to major in science or mathematics, the departments affected could either accept
the QRT results, or require the student to take the MPT. Even if a second test
were required, the amount of testing for such students would have, practically
speaking, a minimum impact of current testing logistics. The
idea of an integrated mathematics/QR test would not lead so obviously to a fork
and has the rhetorical advantage of creating the sense of a more integrated curriculum,
a sense that the University values equally science and humanities, mathematics
and quantitative reasoning. Whichever
test were developed and implemented, the next decision to make would be what to
do with the scores - which would depend entirely on the changes in curricular
policy that are adopted. If no curricular policy change is anticipated, then of
course the whole question of even having a test is moot. If
curricular changes are anticipated, then the issue of testing transfers arises,
and has a very different impact. Currently, transfers take the MPT only if they
are going to enroll in a mathematics course at Western. (Although transfers who
have taken calculus are not tested.) Depending on how QR is eventually woven into
Western's academic fabric, this practice might have to change. If, for instance,
courses with a strong QR component are developed and/or recognized, or if certain
courses get infused with a stronger QR component, and these become required for
graduation, transfers not anticipating taking a mathematics course at Western
might be required to take the QRT for the same reason they take the MPT: to find
out if they are academically prepared for certain courses. If, however, QR is
concurrently woven into the curricular fabric in the community colleges, then
assessing a transfer's QR competence might be addressed any number of ways, with
the QRT being only the most obvious. There could also be transcript reviews; articulation
agreements could be reviewed and revised, etc. [top] WHAT
DO WE CURRENTLY KNOW ABOUT THE QUANTITATIVE REASONING SKILLS OF WWU STUDENTS?
Currently, there is
no quantitative reasoning general education requirement (GER) at WWU. Students
are offered a variety of methods to satisfy their GER requirement in mathematics,
and the Math Placement Test (MPT) is administered to most students to assist in
placing them in appropriate courses, but there is no general quantitative reasoning
test or course available. Thus, we have no data on the QR skills of our students. [top] MEETING
THE CHALLENGE: SOME MODELS FOR ASSESSING QUANTITATIVE REASONING SKILLS
As has been mentioned,
some kind of QR education has been considered as an alternative GUR to the current
math requirement. In October, 2000, a group of faculty from the six public baccalaureate
institutions met at a colloquy in Leavenworth, Washington, to discuss how to define
and assess quantitative reasoning in higher education. Based on those discussions,
but subjectively reinterpreted by the authors of this paper, three models for
the assessment of QR skills will be presented below. In the first, there is a
rubric, but no QR pre-test; in the second, a QR pre-test is the model's centerpiece;
and in the third, aspects of the first two are combined into a hybrid. MODEL
1: This first model is based on a rubric that examines the QR content that
already exists in the curriculum of major disciplines and/or departments. Each
discipline and/or department would need to be actively involved in developing
rubrics that worked within their area. As an example, faculty in the social sciences
who were attending the colloquy described seven statistics-based research components
that could be considered fairly generic in their area, and that would need to
be included in any QR rubric applied to the social sciences. (It was also noted
that not all social science courses contain these research components; nonetheless,
the guiding principle of this model is that disciplines and/or departments are
the most appropriate base for QR assessment.) This model does not use a pre-test
of QR abilities or skills. It rather takes an inventory of QR skills and/or abilities
that already exist within the curriculum, makes a vigorous public acknowledgement
of the existence and importance of QR, and encourages the emphasis of QR in higher
education. It may or may not stipulate that a student must take one of the courses
identified as having a strong QR component in order to satisfy graduation requirements.
The major pitfall of this model is it may not meet the legislative mandate for
QR assessment. MODEL
2: This model borrows heavily from the Wellesley model described earlier in
this paper. The heart of this model is a pre-test of QR skills, administered to
all in-coming students, either as an addition or an alternative to the MPT (math
placement test). Students unable to meet the minimum standards of QR competency,
as based on the pre-test, would enroll in a basic QR course. Those meeting the
standards would be required to enroll in an "overlay" course in which
QR concepts would be identified and evaluated in courses in the major disciplines.
Students required to take the basic QR course would also be required to enroll
in an "overlay" course as a stipulation to graduation. As in MODEL 1,
a discipline and/or department QR rubric would be vital in identifying appropriate
"overlay" courses for students to take. When talking about course logistics
and the best use of resources, the idea of using already existing courses as part
of a QR requirement would be far superior to creating a slew of new ones. MODEL
3: This model would not require a pre-test in QR, but would require all students
to take a basic QR course in addition, or as a supplement to the University's
current mathematics stipulations. This model may or may not include the additional
requirement of a QR "overlay" course, although a discipline and/or department
rubric would still be a sensible, probably necessary plan of action, if for no
other reason than to create a broader sense of QR's current existence within the
curriculum, as well as to respond to legislative concerns. [top] NEXT
STEPS If
any of the above models, or parts of them, were to be adopted into Western's higher
education goals, how will we know if those goals have been reached? Regardless
of the domain - QR, writing, ITL, critical thinking - this problem is central
to all student learning outcomes assessment. Are exit tests the solution? This
strategy has its appeals - straight-forwardness, the promise of quantifiable results,
a clean finality - but is also fraught with problems. For example, who would pay
for the costs? Do we pass them along to students? What about the logistics of
having 2500 people a year sit down for such testing? Do we impact course/class
work by setting aside a week of testing days? What about the messy work of assessing
writing? No one yet has come up with a way of feeding a computer a sample of student
writing and have it spit out a meaningful rating. And what, pray tell, happens
if students don't meet the standards? Do we force them to repeat courses? Do we
hold them back? Yet of all the legitimate concerns over exit testing, what educators
fear most is that exit tests lead inexorably to instructors teaching to the test
rather than their hearts, thereby stifling academic creativity, flexibility, and
innovation. Certainly
a more practical student learning outcomes assessment tool are satisfaction surveys.
Our current ones could be modified to include questions about QR, Information
Literacy, etc. Yet such surveys never seem quite enough. They're a "soft"
measure, subjective and not as representative of our student population as most
researchers would like them to be. While the surveys themselves could be more
finely honed, and return rates could be increased, satisfaction surveys would
only ever be one part of a fuller student learning outcomes assessment effort. Probably
QR assessment will need to tie in to the current student learning outcomes assessment
technique: allowing a well-designed, thoughtfully considered curriculum to take
care of the end results by itself. Yet this approach, too - as steeped in tradition
and as well-intended as it may be - often feels "soft", especially by
today's higher academic standards, driven by the need for objective quantifiable
data. Something
relatively new that might help this student learning outcomes conundrum are the
performance standard rubrics that have been developed, or that are being developed
for the domains established by the legislature. (To date, rubrics have been developed
for writing and critical thinking, while rubrics for information technology literacy
and quantitative reasoning are in process.) What's useful about these rubrics
is how they delineate the expected performance abilities of students at various
levels along their academic careers. That these rubrics have been so diligently
thought out and produced is a very good thing - some might even argue that it's
a process long overdue. Content standards have been debated and produced seemingly
since the inception of education; they are, at least currently, the bases for
most curricular decisions. On the other hand, clearly articulated performance
standards have been either sorely lacking or all but invisible to those outside
academia. So
having the rubrics is good, but what is going to happen to them once they are
honed and ready for use? Will they be used as part of an exit test? Oops. There's
that again. But if not an exit test, what about the idea of applying the standards
of each domain's rubric to the curriculum? What if from day-one to day-last of
a student's academic career each course contained some of, maybe even sometimes
all of the domain skills, with those skills then assessed according to the standards
proposed by the rubrics? Indeed,
by way of promoting a point of discussion, we are going to suggest in this Dialogue
the idea of student learning outcomes assessment serving as a matrix - and here
we are defining matrix as that which gives form to a thing. We are thinking specifically
of calling it an institutional matrix. How
an institutional matrix might work is this: a) here are some domains of knowledge
- writing, QR, ITL, critical thinking - that we want to send our students into
the world with as an educated citizenry; and b) here, as laid out under each domain,
are the rubrics establishing the performance standards for those domains of knowledge.
With the domains and rubrics in place, c) each instructor incorporates into his
or her courses as many of these domains as is appropriate and reasonable; and
d) utilizes the rubrics (also as appropriate and reasonable) to assess student
learning outcomes. It
might be helpful to think of this institutional matrix as an overlay to most of
the existing pedagogical techniques already practiced and courses already taught.
It's worth is as a curricular clarifier, an intensifier, a focuser, the tool with
which murky areas can be made clear again, not just for those of us in academia,
but for those outside it - legislatures, taxpayers, the parents of our students.
For those folks especially clarity is of utmost importance, yet also what many
of them feel academia lacks. Our
current system of courses, grades, capstone experiences, et al., is not necessarily
bad or out-dated, but it is sorely lacking an overlay of contemporary clarity.
It may be that in the course of applying such an institutional matrix there will
be some fundamental rethinking of our goals as higher educators; maybe there will
need to be some discussion about the balance between life-long learning skills
versus content knowledge in the various departments and majors, but such discussions
- and maybe even the reevaluations that might come from them - will not hurt us,
but rather might renew the energies of all those involved in higher education. [top] SUMMARY
QR and math are inextricably
linked, but while math is primarily a discipline, QR is primarily a skill - one
with practical applications. Moreover, while mathematics is often exclusive, frequently
with a language of its own, QR is inclusive, its language plain and everyday.
Few people are trained to work with complex mathematical concepts, but most can
understand mathematics well enough to develop informed opinions about quantitative
concepts. The
expectation that college graduates will demonstrate competence in quantitative
reasoning is broadly supported on both the state and national levels; however,
the assessment of QR skills in undergraduates is complicated. For one thing, QR
crosses domains. For another, important assessment questions have yet to be addressed:
what QR skills should students enter with? what should their QR skills look like
when they graduate? We
have suggested three different assessment models that might achieve the goal of
determining whether our graduates meet acceptable standards of QR competence.
Moreover, we have suggested the idea of an institutional matrix focused in the
general education program that would support, sustain, and encourage the development
of student learning outcomes from each of the four state initiatives - quantitative
reasoning, information technology literacy, writing, and critical thinking - which
form the core of a new and exciting assessment arena for higher education in our
state. Such a broad scale approach to student learning outcomes has enormous potential
to impact how faculty think about student learning in all courses they teach. [top]
