Mathematics courses in high school, at least up to pre-calculus, definitely play a gateway function for students going to college. At the University of Colorado, for example, students who are not able and prepared to do well in calculus right away simply have to abandon any hope of certain majors in the sciences. Moreover, they are completely shut out of a career in engineering. This handicap seems to affect a disproportionate number of students from public schools--including many students of color--where they have not been groomed for higher education by strong advice to stay on track in mathematics from middle school and through high school.
So mathematics certainly does serve as a gateway to certain careers.. What I don't know is whether calculus is absolutely necessary in the pursuit of certain careers that now require it, or whether it plays just a filter role to eliminate students. If this is true, something should be done about it. On the other hand, because mathematics is a rigorous and challenging course of study that trains the mind, I require of my own children that they take the highest level of mathematics possible all through their high schools years--regardless of what they wish to pursue as careers in college and later in life. But I also know that for a variety of reasons (e.g., lack of interest, self-motivation, parental advice, peer support, or good counselling) even in our middle-class suburban school district, many students do not take mathematics every year of high school. In fact many stop after algebra in the 9th or l0th grade.
I have read, however, that Asian-American students as a group tend to take more mathematics classes consistently through high school, which may in turn help explain why these students are more highly represented in the sciences and engineering both in college and subsequent careers. Our inability to keep so many American students interested in mathematics throughout high school is clearly a serious problem, if for no other reason than the need to keep open wide options of future careers.
Question
I am not sure how to define or measure the quantitative skills and knowledge we need to function as adults. With powerful technology so easily accesible, the skills of simple computation that we all used to need seem no longer so critical. The term "numeracy" is not well known, but the term "quantitative literacy" seems to have some appeal. I take it to mean an understanding of the uses of computation and measurement, with some ability to use the associated skills. Minimally, QL requires an ability to understand graphs, tables and charts--and not to be intimidated or put off by them. Although students pick up some QL understanding and skills in precollegiate mathematics classes, QL education should go well beyond formal mathematics classes. We need to find a way to apply what is learned in formal mathematics courses to everyday "real life" situations, circumstances, scenarios and case studies. Question 3 I don't think the problem is a case of either/or--that is, either formal mathematics or "context-rich QL." Rather, it requires re-thinking our expectations as educators as to what quantitative skills and knowledge we hope students going through our educational system should acquire in order to be a functionally literate adult and productive citizen.
Periodically the media picks up yet another report on how low is our mathematics achievement as a nation and how poorly we compare to countries such as Taiwan, Singapore, Japan, Czech Republic, Poland, etc. I don't really know what these stories mean except that, in comparison with other countries that ourperform us on these tests, we don't expect all our students to take a lot of mathemtics in high schools. So while our average scores may not be impressive, I bet our best students who do take a lot of mathematics do as well as the best from anywhere.
I am concerned, whether we talk about formal mathematics or quantitative literacy, that weak schools, poor families, and minority communities seem to produce fewer students with strong mathematics background, thereby creating an obstacle which blocks students from pursuing--or even imagining--certain careers that are creative and rewarding both intellectually and financially. For me, that creates a critical social problem because it widens the existing gaps between classes and races.
You note that technology makes many traditional quantitative skills seem "no longer critical." Many high school students draw the same conclusion--which may explain why so many drop out of mathematics as soon as they are allowed to. If advanced high school mathematics is no longer necessary for life and work, but only critical for those going into the hard sciences, what persuasive reasons can be given to those who do not aspire to be a scientist or engineer?
One of the chief problems for students who opt out of mathematics too early is that they foreclose certain careers. If a student doesn't continue in mathematics through calculus or pre-calculus while still in high school--perhaps for lack of early interest in pursuing a career in science or engineering--that student will need to do a lot of catching up if he or she discovers later on that indeed, science and engineering are interesting after all. So I would never discourage students from taking mathematics every year of high school. I agree, however, that because of the ready accessibility of inexpensive and powerful calculators, many students probably don't see the need to learn computation skills, and certainly not to hone those skills to perfection. Nevertheless, I believe that all students should take a lot of mathematics in high school no matter what their eventual career and life goals may be because mathematics teaches us to think in a systematic and disciplined way. I think these skills can be transferred to other areas of study and work.
Although calculus has been--and still is--an important prerequisite for students going into the "hard" sciences, for many other fields (e.g., medicine, business, public policy) statistics and computing are much more important than calculus. Does this suggest that we should give students more choice earlier in their academic careers--perhaps after grades 8-9 or so? Might this convince them to stay in mathematics longer?
I notice that high schools are introducing new mathematics sequences and courses, notably statistics and computing. I think these are all good options, and that the calculus sequence should certainly not be the only one available to those students who want to continue with mathematics. Having such options will probably encourage more students to stay with a mathematics or quantitative skills sequence. (Here, as elsewhere, I use "mathematics" as a shorthand to include all types of quantitative reasoning and skills courses.)
Jerry Bentley,University of Hawaii As the social sciences (including history) have come to rely more on quantitative data, statistical methods have became a routine part of undergraduate programs. To what degree do history and the social science courses in high school reflect the increased quantification of these disciplines? In particular, do these courses do much to enhance students' nascent QL skills? If not, do you think that they should or could do so?
Actually, there has been a fairly sharp and clearly detectible move away from quantitative analysis in professional historical scholarship. For some time now, the move has definitely been toward qualitative and especially cultural analysis. But that doesn't mean that quantitative concerns should not be a part of history education. To the contrary, introducing quantitative literacy across the curriculum would make a welcome complement to writing across the curriculum. My suspicion is that high school courses make little effort to deal with quantitative issues, although my only real basis for this judgment are the reviews I prepared for publishers of two high school textbooks in world history. My suspicion is that if you tried to smuggle quantitative issues into history by way, for example, of economic history, students would complain that this is a course in history, not economics, so why do we have to count? My response would be that all disciplines and fields overlap to some greater or lesser extent with others, and if you want a reasonable understanding of the world and the way it works, you have to take a lot of considerations into account.
As you know, many critics have faulted higher education for failure to ensure that all graduates are well-equipped in basic knowledge and skills. How important is quantitative literacy in the priorities of colleges and universities today? Is there any consensus on the nature and level of QL that a college degree should represent? Do colleges know how numerate their graduates are? Do they care?
The University of Hawaii requires all undergraduates to complete a course in either logic or mathematical reasoning, but I suspect that there are lots of institutions with no such requirement. My own sense is that our requirement is just about right. There are a very few people who simply cannot deal with numbers, just as there are a very few who cannot learn a foreign language. For those very few people, there needs to be an alternative to a mathematics or foreign language requirement. For mathematics, logic is an obvious alternative.
Most of the commissions that have weighed in on college and university curricula seem to believe that some kind of quantitative coursework is desirable for all undergraduates, but I don't have a sense how many institutions make mathematics a core requirement. Colleges certainly have no idea how numerate their students are. Basically they don't care, or if they do they don't have the time, money, or motivation to develop tests that would reveal the level of numeracy among their students.
Perhaps gratuitously, I'll add that a large part of the problem with mathematics at the college level are the mathematics departments. For twelve years I've served on our core curriculum committee, and I have always been a very strong supporter of the math-or-logic requirement. But mathematics is probably the biggest source of student complaint about the core curriculum. The mathematics faculty seems to think that some sort of minor league professional mathematics is the appropriate thing for undergraduates completing core requirements. My own sense is that something on the order of mathematical thinking--and I hope you don't ask me for a definition of that!--is a lot more pertinent for most undergraduates.
Many people talk as if QL skills are somehow different than what is taught in school mathematics. Do the terms "mathematical literacy" and "quantitative literacy" mean different things to you? Are there any significant differences between what tends to be taught in school mathematics and what you would expect of a numerate citizen?
Well, this question is asking precisely what I hoped you would not ask! Indeed there are ways in which quantitative literacy would be different from a mastery of mathematics at either the beginning or advanced level. Maybe it has partly to do with allergies and phobias. Some people-- numerophobes--are allergic to mathematics. QL would enable such folks to deal with the kinds of quantitative issues we all face every day, even if they couldn't make their way very far through set theory or topology. QL might even make it more difficult for politicians, public officials, lobbyists, public relations types, and others with particular narrow interests to manipulate opinion and flim-flam the general public. That obviously happens quite frequently. Because of their math allergy or numerophobia, many people don't bother to think about the logic of their arguments. So indeed, some kind of preparation that would help people realize that numbers are not scary--that would help them engage quantitative data rather than breeze over it with glazed eyes--would be most appropriate for citizenship in these times.
Why do colleges have QL requirements if they don't care how numerate their graduates are? Are they so wedded to an "input" system of controls that they disregard outputs? Is this true for other elements in liberal education, or is it peculiar to QL? Might it be because they don't really know what they mean by QL?
Actually, I'm not sure that many colleges do have QL requirements. Mostly, I would guess, they have math and logic requirements, which are not necessarily the same as QL requirements. Personally, I wouldn't doubt that all faculty and administrators care deeply that their graduates are numerate, but it is a very difficult thing to prescribe meaningful requirements for large numbers of people. It is almost impossible to guarantee that a respectable percentage of students will graduate with the desired outcome of almost any course at all. Moreover, the curriculum is contested ground, since all departments and disciplines want bodies to justify their existence (and growth). The required core curriculum is both a political and an educational compromise that sometimes works well but often completely flops. This much is true for all fields and disciplines. When it comes to quantitative courses, the problem hinted at by your previous question also comes into play. For most people, quantification brings mathematics to mind and there is little awareness that there might be something such as QL distinguishable from mathematics.
2. Some research studies have shown that the study of logic does little to make people think logically. [Mathematicians are a good example: they know formal logic quite throughly, but are hardly more logical in argument than other faculty.] Much the same can be said of courses in statistics and algebra. Some claim that if students see logic and statistics *used* in context (e.g., in a history or econonomics course) they are more likely to be able to use it later. Might this suggest that QL is better taught in courses like history (even if it requires smuggling it in) and economics rather than in algebra, statistics, or logic?
Interesting idea here, on the order of writing across the curriculum. But basically I don't think it would work. For my own part, I might occasionally deal with some quantitative issues in history courses, but QL cannot be the focus of my courses, and I couldn't deal with quantitative issues in any kind of systematic way. Some students might well see the significance of quantitative reasoning better if it were in some real-world context, but I don't believe you could do quantification across the curriculum systematically enough to ensure that many students would graduate with respectable QL. In addition, a lot of instructors themselves are not at a QL level that would enable them to deal effectively with quantitative issues. A more realistic approach might be for instructors of courses in mathematics, logic, and statistics to frame their lessons with real-world examples.
Michele Forman, As the social sciences (including history) have come to rely more on quantitative data, statistical methods have became a routine part of undergraduate programs. To what degree do history and the social science courses in high school reflect the increased quantification of these disciplines? In particular, do these courses do much to enhance students' nascent QL skills? If not, do you think that they should or could do so?
Before responding, I need to note that the social sciences definitely do not include history. History is in the humanities. The social sciences are predominantly a late 19th and early 20th century development that applies "scientific" tools to human society. The two disciplines occasionally overlap, but generally use very different lenses to view the world. Names are very touchy issues to many in the field (but not to me). I don't teach social science. I'm an historian, so I can only answer in terms of history teaching and learning.
Good history courses in high school strongly reflect increased quantification, especially through social history that often relies on demographic or other quantifiable data. Sometimes our work does increase (or at least emphasize) the importance of what students know and can do relating to these quantification skills. For example, when examing historical evidence in the form of a graph, I might ask my students to explain how the graph would appear different (while containing the same information) if we were to collapse the y axis by half. We can discuss how this might affect superficial interpretation of the evidence. And what study of Islam would be complete without Islamic art and tesselations? (Escher was inspired by the Al-hambra in Spain.) I definitely think that history teachers should consciously integrate numeracy skills into teaching because (a) interdisciplinary teaching is important and effective for all of us, and (b) we need these tools as historians. After all, even a timeline involves quantification.
Many people talk as if QL skills are somehow different from what is taught in school mathematics. Do the terms "mathematical literacy" and "quantitative literacy" mean different things to you? Are there any significant differences between what tends to be taught in school mathematics and what you would expect of a numerate citizen?
I certainly have a limited understanding of these terms, but I think of "quantitative literacy" as being a subset of "mathematical literacy"; quantitative literacy is similar to (or the same as) "numeracy". I see mathematical literacy as going beyond working with numbers or arithmetic. I believe our more capable students are well prepared as numerate citizens, but our weaker students are not. Students who fulfill their mathematics requirements with "general math" or business courses learn very useful skills, for example, but miss out on learning how to reason abstractly.
I understand mathematics to be another language, and like all languages, it allows us to interpret our universes differently. Because mathematics increases possibilities for interpreting evidence, it helps us see the world from different vantages and reason better and more creatively . I would certainly hope that all students are exposed to mathematics beyond arithmetic.
For a host of different reasons, many students arrive in college not fluent in elementary (high school level) algebra, geometry, and statistics and are therefore unprepared for the quantitative demands of courses in the natural and social sciences. Often colleges respond by providing supplementary (non-credit) QL programs that help students remediate these deficiencies. Question: Should more than that be required for graduation from college? In other words, should numeracy for a college graduate represent something beyond entrance-level expectations? If so, what should it be?
I endorse raising graduation standards. While certainly not a mathematics teacher, I nonetheless believe that the vast majority of our students are significantly more capable than we have thought them to be--in history, mathematics, and other disciplines. As for college, numeracy must involve more than entry-level expectations, especially since these are so weak at many colleges. I am puzzled that our students recognize the importance of mathematics education (a student of mine once wrote in a paper, "Without math, you can't have a life.") but many avoid taking challenging mathematics courses. Only college entrance requirements drive many of my best students to take higher level courses in mathematics.
Pam Paulson Despite strong links between mathematics and some aspects of the fine arts (e.g., musical scales and rhythm, perspective drawing, digital image enhancement, computer-based choreography), most people still think that quantitative literacy is primarily important for the natural and social sciences. In your view, how important is QL for students interested in the arts? What kind of QL is most important for them?
Basic quantitative literacy sneaks into many aspects of the arts and is key to realizing expression of what is in the mind's eye. Students seem to have a new appreciation for numeracy when it is connected to the art form they work in, especially when it is necessary to the application of their ideas. Measurement comes into play in every art form. Fractions are important in technical theater, music, visual arts, and dance. New computer programs have encouraged many new ways to connect the arts and mathematics. Any time you are mounting an arts production you are involved in basic mathematical computations for ordering materials and supplies, dealing with budgets, sewing costumes, angles for sets and lighting, etc. Artists definitely need basic mathematical literacy.
Mathematics is a subject that students love to hate. In school, many drop out as soon as it becomes an elective; in college many take mathematics only if it is required and even then often put it off as long as possible. Do you have any advice for mathematics teachers and curriculum developers about how mathematics can be made more attractive to students who like it least?
Based on our experience at the arts high school, we have found that when mathematics is taught as an extension of the arts, students find it relevant and important. They see the connections applied as they create and perform their work. Students have made tesselations in drawing, worked with fractals in dance, created model set designs, etc. As long as students can see first hand the relevance to their interests and goals, they perceive mathematics as an important area of study. Unfortunately many arts teachers also feel uncomfortable with mathematics, and may not do as much with it as they might.
Do the terms "mathematical literacy" and "quantitative literacy" mean different things to you? Are there any significant differences between what tends to be taught in school mathematics and what you would expect of a numerate adult?
There does seem to be a difference between what is taught in school and what most adults in the arts seem to need to know, although some of the new integrated mathematics programs appear to be helping bridge this gap. The basic literacy skills of computation are essential. Reading and understanding data and graphs is also important, as well as basic geometry. Finding and creating patterns is a very important part of the arts. Problem solving is also critical.
Although there are many links between mathematics and the fine arts, most of them are invisible to the public. How do we get students and parents to recognize this link--as they now recognize the link between mathematics and science? Will high school counselors ever tell students that mathematics will be a big help to a career in the arts?
The kinds of mathematics used most varies by arts area, so one of the important considerations in making links visible is to be clear about the kinds of mathematics being used. For example, theater and visual arts focus more on geometry, while music relies more on algebra. However, because computers can calculate things like sound waves and tuning frequencies, most students don't learn the mathematics: they just learn how to operate the electronic equipment. Media arts also relies heavily on computer use, for example to calculate such things as focal length. In dance the connections often revolve around using mathematical models as structures for choreography. There is also the use of planes and just plain arithmetic. Budget and cost considerations cross all of the arts areas.
Once the types of distinctions between arts areas are more visible, it is easier to talk with students and teachers about their relevance. But then we run into the next stumbling block: although describing these distinctions and connections may make sense in a verbal conversation, I don't think parents will understand these links based only on verbal descriptions. It will probably also take some application on their part. The parents will have to actually put some of the concepts into action. By starting this kind of description for parents when their children are in the early grades, they will have a better chance of seeing the links. For example, parents can easily understand patterns in an activity, but not necessarily just from a verbal description. Having mathematics/arts examples used in interdisciplinary contexts will help.
We have found that few counselors ever tell students about opportunities to major in the arts in college because most don't believe there are worthwhile careers in the arts. Of course this depends on the individual and their background, but I think it is a long way off for counselors to realize themselves that there are career opportunites in the arts and that there are connections with learning in other subject areas like mathematics.
Your list of quantitative skills needed by adults and artists omits the one subject that is dominant in high school mathematics classes, namely algebra. Do you think we need a different kind of high school mathematics to make it appealing and useful to arts students?
Indeed, algebra is the one area of mathematics it is hard to grasp in many of the arts areas. In some cases where it is important the electronic equipment programmed with the algebra does all the work, so students only need to operate the equipment. In my opinion, the integrated approach works best for students in the arts. Students have a very hard time connecting the segmented parts of mathematics by themselves. They really need help to "add it all up." At the Center we are using a new book called Discovering Geometry: An Inductive Approach that is filled with color images and art works including, for example, Islamic art as examples of mathematics. It also deals with optical art and perspective and relates these concepts to the arts. Coming in the back door has been successful with many students. First they see the beautiful line drawings, for example, and then after they are intrigued, they ask, "how can I learn this" and "where is the compass?"
Peggy Skinner
Is QL different from mathematical literacy? Are the teachings different
from the uses? I think there is a difference. Aside from simple
calculations, the most important concept for individuals to understand is
proportion. In real life, individuals are constantly asked to think
about issues that relate to percentage or doubling or halving something,
for example, to calculate how to double a recipe, to determine an 8%
sales tax, or to understand a risk factor for disease. It is interesting
that of all the calculations that students use, the easiest for them is
the calculation of their percentage score on a test. Here they create
their own need to know. Students are taught these kinds of skills in
lower and middle school, but not necessarily in upper school unless they
take a statistics and probability class. (Our school offers that class
to those who they define as nearly mathematical illiterate because they
did not succeed in algebra and move along smoothly to pre-calculus and
calculus). I define a subject-literate individual as one who knows and
can use information. A numerate citizen actually uses very little of
their mathematical skills.
Although everyone says that quantitative skills are essential for
success in science, the science most students see in high school uses
very rudimentary QL methods--typically just those of the middle school
curriculum (e.g., formulas, graphs, averages). Can the teaching of QL be
embedded in science courses, or is it better left to the mathematics
teachers?
I certainly have to teach basic QL skills. Even though we have an
excellent mathematics department, the students cannot always make the
transition from one class to another, especiallly if the timing is not
quite right. Science teachers spend a good deal of time teaching basic
mathematical skills. I teach percent change many different ways in grade
9-10 biology. Every time I present it during the year (about 4 times), I
leave the formula on the board but the students still work hard. Science
teachers typically have more ways to demonstrate how a principle is used
than math teachers do. Moreover, they have the equipment needed give
each concept a conceptual framework.
As you know, mathematics is often called a "critical filter" that
blocks students with weak school education from rewarding careers. Some
fault the pristine formalism of mathematics which poses seemingly
insurmountable hurdles for many students; many now argue to replace
formalism with a practical, context-rich quantitative literacy. Just how
important is it for all students to master formal mathematics? Is
context-rich QL a more reasonable expectation?
This is a hard question that hits philosophical issues. Should you track
students? Should only some of the students take a road that includes
mathematical literacy? It is clear that using it will make students
follow a traditional series of classes. When one filters and then places
students, those that survive will continue to take additional classes.
Many of those students will be well served by the rigor and skills that
they encounter in preparation for future work in engineering,
mathematics, or physical sciences. Those that do not take that road do
not need to master formal mathematics. Most individuals find that life
uses only simple algebra or the interpretation of graphs--probably no
more than 8th grade mathematics.

Many people talk as if QL skills are somehow different from what is
taught in school mathematics. Do the terms "mathematical literacy" and
"quantitative literacy" mean different things to you? Are there any
significant differences between what tends to be taught in school
mathematics and what you would expect of a numerate citizen?
Quantitative literacy is different from what is traditionally taught in
school mathematics, although not necessarily what would be taught if the
NCTM standards were more widely implemented. For example, I expect
people who have QL skills to be able to think in orders of magnitude when
appropriate, make reasonable estimates of various quantities (including
linear, area, and volume measures), find shortcuts to arithmetical
operations to do in their heads, do ratio/proportional reasoning and
arrive at good approximations, and have developed some spatial and
directional sense. I also think people should be able to relate various
types of graphical information to their numerical expressions, taking
account of scales (linear, logarithmic and other curves), smoothing of
data, and the rationales behind various projections. They also need to
understand the kind of information that is carried on consumer labels
(e.g., food, appliances). I don't believe traditional school
mathematics teaches these competencies.
As you know, mathematics is often called a "critical filter" that
blocks students with weak school education from rewarding careers. Some
now urge that students learn algebra at earlier ages, while others fault
the pristine formalism of mathematics for posing seemingly insurmountable
hurdles for many students. Just how important is it for all students to
master formal mathematics? Might a context-rich experience in
applications of mathematics be a more reasonable expectation for all
students?
It is important for all students to learn quantitative literacy skills
that will serve them the rest of their lives. More and more, information
is going to be provided in visual terms, so this too should be taken into
account in thinking of the mathematical needs of all students. So I do
believe in an applications- and context-rich approach to mathematics--but
only in part. Many students are turned on by quite abstract mathematical
puzzles, even if they don't have any immediate practical applications.
This is also true, I believe, of some areas of mathematics that have
completely dropped out of the curriculum, such as construction geometry.
Altogether, the US curriculum is weak in geometry, an area of mathematics
that has high aesthetic appeal for many students.
I do believe, therefore, that all students should have some exposure to
formal mathematics after exposure to various other types of mathematical
experiences. It seems to me the argument about algebra, however, has
some aspects of illogic about it: if students who now take algebra do
well in their subsequent schooling, then (so the argument goes) if all
students took algebra, they would all do well in their subsequent
schooling. In other words, this popular argument would have us believe
that if A (an unknown factor) leads to B (taking algebra) and C (doing
well in school), then B by itself leads to C.
Mathematics is a subject that students love to hate. In school, many
drop out as soon as it becomes an elective; in college many take
mathematics only if it is required and even then often put it off as long
as possible. What should change--the subject (perhaps from mathematics
to QL) or the approach? Can an emphasis on QL help resolve this age-old
dilemma?
I'm not sure what the distinction is between the subject and the approach
to it. QL has to be based in good understanding of a number of important
mathematical concepts, although possibly not in all that are necessary
for mathematical literacy. Also, as I said, some formal mathematics
should make up part of the path toward QL. At some point it would be
interesting to explore the distinction between QL and ML, that is, what
underpins QL versus what underpins ML, and what the differences in
expected competencies really are. If we agree that everybody needs QL,
but ML is variable depending on your profession (software engineer,
physicist, financial analyst, social scientist, biostatistician), then
perhaps we can better define what aspects of ML extend beyond or are
different from QL.
You say, as do many well educated people, that many students are
"turned on by quite abstract mathematical puzzles" and that "all students
should have some exposure to formal mathematics." But what about the
many students who are *not* turned on by abstract mathematics? Why should
all students be expected to learn formal algebra, for instance, in
addition to the broadly useful QL skills you describe?
I don't mean to suggest that all students should be forced to take whole
courses in formal mathematics such as algebra or calculus. What I do
mean is that as students, with the help of their teachers, find
"shortcuts" to mathematical operations based on regularities, they should
get assistance in making those explicit and in learning some of the
underlying structures that make the shortcuts work. In this way, formal
mathematics enables further strides in mathematical thinking.
As you point out, school mathematics has not traditionally emphasized
the kinds of things you describe as important for QL. But is QL really
the responsibility of mathematics teachers, or might students learn more
QL if it were embedded throughout the curriculum with all teachers taking
responsibilty?
You raise a very good point. I guess the real question is: What will be
harder, getting mathematics teachers to go beyond the traditional
curriculum, or getting all the other teachers to teach what they will
consider the mathematics teacher's responsibility? I'll offer a quick
anecdote: I was observing a 7th-grade science class doing a lab on
conservation of mass, which involved weighing some water in a beaker on a
triple-beam balance. The particular student I was observing had done
everything correctly. However, when it came to the weighing, she
couldn't figure out whether she had .147 grams, 1.47 grams, 14.7 grams
(the right amount) or 147 grams. I told the teacher afterwards that this
student was having problems with the decimal system and place value,
whereupon the teacher shot back: "That's the math teacher's job!" (Of
course, this is also a good example of the student having no sense of
quantities!) Well, there you have the dilemma in a nutshell.
Richard Millman
All colleges have some kind of QL requirement but it is nearly always a
mathematics requirment and many times not well thought out. I am
reminded of Uri Treisman's comment in response to precalculus being
required of all students that a final course in a subject should never be
"pre-" anything. Part of the issue is that our institutions are so
different. My view of the correct procedure is to first ask what is your
mission and purpose and what are the educational goals you derive from
them? Thus there would be many different types of QL requirements.
Most institutions have no idea how numerate their graduates are. The
liberal arts colleges may care, but it is not a very widespread concern
on campus. Most often, numeracy is delegated to the mathematics
department where it is viewed as mathematics requirement rather than as
QL.
Many people use almost interchangeably terms such as "quantitative
literacy," "mathematical literacy," "quantitative reasoning," and
"numeracy," the latter especially in British commonwealth countries.
What's your view about the relation of mathematics to QL (or QR)? If QL
is different from mathematics, and if mathematicians and mathematics
teachers are responsible for teaching mathematics, then who is
responsible for teaching QL? As you view QL, is it something that
mathematicians and mathematics teachers are particularly qualified to
teach?
Each campus should have a QL committee with representatives of
departments who could teach the subject (quanitative social scientists,
mathematics, computer science, etc.) plus some "laypeople.". But again:
what you want as an educational goal for your students is the crucial
first step.
Some colleges have introduced "mathematics-across-the-curriculum" as a
strategy to infuse QL skills in students who (sometimes for good reason)
resist taking mathematics courses. Is it reasonable (and effective) to
think of QL like writing--as a responsibility of the whole faculty and as
something that should be emphasized to some degree in every course? If
only science faculty stress QL, will the average student take it
seriously? On the other hand, does anyone other than science faculty
really care?
In an ideal world, quantitative literacy should be across the curriculum.
Unfortunately, people outside the sciences (plus a few social scientists)
are phobic about mathematics or QL and would hate to teach it. (Look at
what happens when mathematicians are asked to put writing in their
courses. Of course, I like it personally but there are many others who
refuse.) I am afraid that "mathematics across the curriculum" is doomed
by exactly what we are trying to combat: mathematical or quantitative
phobia. Having said all that, when Knox makes a curriculum change (which
we are starting now), I will propose mathematics (or QL) across the
curriculum.

A common pattern on many campuses is to require a foreign language of
B.A. students and mathematical (or quantitative) skills of B.S.
candidates. Other institutions embed similar choices--mathematics or
foreign language--in their general education requirements. Does this
alternative make educational sense? Is quantitative literacy analogous
to foreign language literacy?
Our general education is in two sections: core requirements for all
students regardless of degree sought and degree-specific requirements.
Core requirements include composition, American institutions, computer
literacy and quantitative literacy. The latter can be fulfilled by
achieving a score of at least 65 on the COMPASS algebra exam, a score of
at least 3 on the AP Calculus or AP statistics exam, or by taking a 3-
credit mathematics course (Contemporary Mathematics, Statistics, College
Algebra, Pre-calculus, or any higher-level mathematics course). The B.A.
or B.M. degrees require, in adddition, two years of foreign language (or
equivalent). B.S. students must take six credit hours over and above
the general education requirements that emphasize scientific inquiry.
Nearly one hunderd courses are available to fulfill this requiremement,
including seven offered by the mathematics department.
Thus we do not see FL/QL as alternatives in general education although
FL/SL (scientific inquiry) do define degrees. Defining the B.S. this way
is new and came about during the semester conversion process we went
through recently. I think the faculty didn't like the B.S. being called
a "default degree," so now it has some substance. One consequence is
that we're having fewer English majors with a B.S.--and that's fine with
me. They'd rather fulfill the FL requirement for the B.A. than take more
mathematics or science.
I might mention that we have compatible requirements throughout the state
system for the general education component. This was achieved during
semester conversion in order to make transfer of general education more
uniform. We have an agreement that if general education is completed in
one state institution, the other accepts the whole general education
package.
For a host of different reasons, many college students are not fluent
in elementary (high school level) algebra, geometry, and statistics and
are therefore unprepared for the quantitative demands of many courses in
the natural and social sciences. Often colleges respond by providing
supplementary (non-credit) QL programs that help students remediate these
deficiencies. Question: Should more than that be required for
graduation? In other words, should numeracy for a college graduate
represent something beyond entrance-level expectations? If so, what
should it be?
We offer two remedial courses in mathematics for those not prepared for
the quantitiative literacy courses: Pre-Algebra and Elementary Algebra.
Special fees are paid to support those courses and credits do not count
toward graduation. The courses should help students succeed in the QL
courses which they still must take and pass. These are not substitutes
for meeting the requirements.
Some colleges have introduced "mathematics-across-the-curriculum" as a
strategy to infuse QL skills in students who (sometimes for good reason)
resist taking mathematics courses. Is it reasonable (and effective) to
think of QL like writing--as a responsibility of the whole faculty and as
something that should be emphasized to some degree in every course? If
only science faculty stress QL, will the average student take it
seriously? On the other hand, does anyone other than science faculty
really care?
We don't have a mathematics across the curriculum program and I wouldn't
expect us to do so. Frankly, our mathematics department is the least
connective across disciplines and we have had to hire people with good
high school backgrounds as instructors to meet the needs of the
developmental and QL courses. Our regular mathematics professors are in
a world of their own. As we get more students into the new B.S. track,
my guess is that most students will meet the "scientific literacy
requirements" through course in natural sciences, business, and
measurement courses offered in social sciences and not in mathematics.
Often one hears that QL issues become confused (or incoherent) when
they are externally prescribed through state-wide articulation agreements
that may not match the situations of individual campuses. What's your
sense of how well Utah's state-wide articulation in working?
For transfer students there are certainly advantages to the articulation
agreemeent among state institutions. What we have agreed to is a
'parity' arrangement whereby if students complete the general education
package at one university, it is considered to be "locked in" and can be
transfered as a block to the other institution. (This is similar to what
one does with an Associate's degree.) If a student has not completed the
entire general education block, then we apply parity: students who did
75% of general education at one place, are considered to have done 75% at
the other. The trick then is looking at what was done and what was
not.
This system was imposed by the Regents through the back door of semester
conversion. They brought together state-wide discipline-based teams with
representatives from each campus to coordinate their course numbering
systems, etc. While they claimed they did not want "cookie cutter"
institutions, that is exactly what they did want. By working with
disciplinary groups to seek conformity, they in fact created practically
identical general education packages without ever looking at general
education as a whole. Once the science, foreign language, mathematics
and other faculties agreed to what they wanted, you ended up with a
general education package that had never been debated as a whole or
passed through an individiual faculty senate as a single construct.
The only institution that held out was Utah State. They had recently
gone through a general education revision that included upper division
general education courses, which reflects a trend at a number of schools
who have revisited general education in the last decade. Admirably in my
opinion, they held fast with keeping some general education at the upper
division and will require transfer students to take those courses. At
Weber, we lost our requirement to have a required literature course which
had been part of our package. The English department didn't fight for it
(they just gave up) and are now realizing how it has affected their
enrollments and the balance with writing in the department. Formerly,
most faculty taught almost equal shares of literature and composition.
Now their loads are 3/4 composition.
My concern is that we do not have a thoughtfully created, widely debated
general education on campus. We might have ended up in the same place
since when push comes to shove, most debates on the academic issues
associated with general education break down into a type of distribution
requirement. But now, as a result of articulation issues, we have a
distribution system based on convenience of transfer above all else!

Many people talk as if QL skills are somehow different from what is
taught in school mathematics. Do the terms "mathematical literacy" and
"quantitative literacy" mean different things to you? Are there any
significant differences between what tends to be taught in school
mathematics and what you would expect of a numerate citizen?
It appears to me that mathematics has two foci. One is a way of thinking
and reasoning that allows a person to solve some types of problems. The
other is a set of tools (arithmetic, algebra, geometry, trigonometry,
calculus) that enable, support, and provide context for these problems.
To me, the use of the tools is mathematical literacy, while the tools and
thinking together constitute quantitative literacy.
My experiences with contemporary school mathematics is limited, but my
impression is that there are schools in which quantitative literacy is
emphasized more than the use of the tools and the reasoning that these
tools support. However, there are also schools where the use of the
tools without a purpose or context is emphasized. In some places the use
of tools is a criteria for entrance into advanced courses and therefore
the skills of using these tools becomes a limiting factor for
students.
I guess I would prefer a salesclerk who could estimate or calculate a
discount over one who knows calculus but does not have these skills.
Schools are under pressure these days both to prepare students for
college (SAT, AP, etc) and to meet the needs of the modern high-
performance workplace. These different goals emphasize rather different
mathematical areas (e.g., the former, advanced algebra and formal
methods; the latter, data analysis and contextualized problems). Can
teachers do it all? Can students learn everything they must learn? How
would you sort out what is essential QL from what is optional?
This question highlights the ambiguity of the American public about the
purposes for schooling. We seem to expect our schools to satisfy
different purposes for schooling: the liberal ideal that
represents certain types of knowledge because this is what all educated
persons know, the needs ideal which focuses on being able to
function in the work place, and the student-centered ideal which
focuses on the development of persons. There is no way that schools can
teach all that we expect citizens to know for all three purposes.
Although it has become a cliche, I would suggest less is more. Focus on
teaching fewer mathematical concepts, but choose those that have the
greatest mathematical power and current and predictable social impact.
Then teach these concepts with reasoning about their development and
utility.
Is it better for the skills that are central to quantitative literacy
to be taught primarily by mathematics teachers or to make QL a
responsibility of all teachers in all subjects, embedded in every course?
Even if the latter might be ideal, is it practical? Are teachers QL?
Will they willingly and eagerly push their students in this
direction?
I may be old fashioned, but I believe that at the middle and high school
level quantitative literacy should be taught by those who have a depth of
understanding of mathematics (which is prerequisite to quantitative
literacy), and that is the mathematics teachers. Teachers cannot be
expert in all disciplines. What is distributed across the curriculum is
easily overlooked.

your vision of the quantitative abilities of a numerate citizen?
Is there a core that absolutely everyone should know and be able to do?
I would define the core in terms of the kinds of tasks that citizens
should be able to complete successfully. As a voter, that would include
understanding the quantitative arguments made in voter information
pamphlets like the one issued by the secretary of state in California, or
by politicians about sich things as the federal budget, the deficit, the
debt, or the balance of payments. The issue is not arithmetic, but
compound interest, extrapolations, and underlying models. For example,
one recent voter initiative dealt with complex projections of growth by
tying the schools budget increases to the lesser of the increases in the
school age population, the total population, the state's cost of living,
and the national consumer price index.
As a consumer, the core would include number sense, estimation ability
(to recognize when a scanner is broken, or that something was entered
twice, or with a misplaced decimal), and the ability to figure out
personal finances such as whether it's worth taking out a loan to pay off
your credit cards. To stay healthy, consumers also need to be able to
read and interpret nutritional labels, and to figure out what information
is relevant for oneÕs own diet and health choices.
As a patient, the core would include interpreting statistics to decide
whether to have surgery and to be able to formulate appropriate questions
about medical data (For example, for such and such surgery there's
generally an 80% success rate. However, given your age and physical
condition, the likelihood is somewhat lower. There's a 5% mortality rate
from the surgery, and a 20% chance of serious postoperative
infection.)
As an employee, apart from job-specific skills, thereÕs an increasing
need to be able to develop spreadsheet models and Òwhat ifÓ
manipulations, as well as an ability to decipher quantitative
information, interpret it, and communicate it to others in forms (e.g.,
graphs, charts, tables, formulas) that make sense in context.
I could go on enumerating, but you get the idea. The core includes
mainly arithmetic and middle school concepts, emphasizing a facility with
estimation, manipulation using technology, or mental arithmetic, all of
it in context, all of it sense-making. This program has very little
overlap with traditional school or undergraduate mathematics.
I am ambivalent about including Òenough mathematics to have opportunities
to learn new things.Ó On one hand, thatÕs the time to learn it, in the
context of nursing or studying science or whatever. But on the other
hand, as a matter of equity, what I have said above looks suspiciously
like Òcheckbook mathÓ and you know thatÕs not what I mean. The problem
formulation (what do I pay attention to?), implementation (what model
makes sense?), and conclusion (does the answer make sense?) ought to be
enough to get people into the door of the courses that they need, but it
isnÕt.
Just how important is it for all students to master formal
mathematics? Might a context-rich experience in applications of
mathematics be a more reasonable expectation?
More reasonable to whom and for which students? It is no more important
for all students to master formal mathematics than it is to be able to
recite ÒArma virumque cano,Ó or to know which fork to use at a formal
table setting. And it is no less important. I learned those things, and
many more (e.g. ÒDonÕt wear white shoes after Labor Day or before
Memorial Day,Ó) and they have served me extraordinarily well. As long as
such symbols are held in high esteem, access to them and success in them
are the right of all students.
If we can get society (and particularly some mathematicians in
California, I assume that you arenÕt going to quote me verbatim, but you
know exactly which ones I mean) to recognize that an elegant proof is not
superior to an elegant aria or an elegant three point shot in basketball,
then we cannot replace the traditional standards with ones that make more
sense. Yes, I think that every student should be pushed and supported to
achieve excellence at the highest levels in some spheres; call that
mastering formalism. And I think that every student should be given
opportunities to learn well things that are useful and important as
citizens, voters, consumers, etc.
Of course I think that content-rich experience in applications of
mathematics is a better goal for all students, but until itÕs widely
valued, then it sells some students short. In my own experience,
content-rich applications (studying physical chemistry) actually got me
interested in mathematics per se. IÕd skated through calculus, but was
jarred into interest in math when a chemistry professor said, at the end
of my freshman year in college, ÒIÕm not happy with this course being
based on differential equations. Does anyone want to audit Linear
Algebra with me next year and see if thatÕs a better model for the
chemistry weÕre trying to describe?Ó All the tumblers fell into place
for me. I did audit the course (I never thought to take it for credit,
as I was simply interested in learning the stuff) and he did rewrite the
course and the book for the course. Whew! But I had already passed
Calculus III, so I could afford to learn mathematics to answer a question
that was meaningful to me. (Of course you can say that this was an
unusual professor at a liberal arts college who had time to revise
courses and involve undergraduates and that I was an unusual freshman.
Yes, but when I taught middle school mathematics I found that even the
conventionally best students were far more engaged in meaningful
problems, where the generalizations and abstractions and formalisms were
their own, derived from the contextualized and concrete.)
We have a political problem here, which in some places, as you know, has
become partisan and very mean-spirited. I console my friends whoÕve been
on the front lines in California that the reason that we have the problem
is because we have had some success, that we have taken all students to
heart and actually made a dent in the social order. I truly believe that
we are at a crossroads, that we may have to wait another generation if we
donÕt navigate these shoals successfully, but that we have to create a
social and political climate where your innocent question isnÕt so loaded
and the answers to it arenÕt so guarded. The good news and the bad news
is that ten years ago I would have answered the question, ÒFormalism, no.
Context-rich, yes. Next question.Ó
Many critics have faulted higher education for failure to ensure that
all graduates are well-equipped in basic knowledge and skills. How
important is quantitative literacy in the priorities of colleges and
universities today? Is there any consensus on the nature and level of QL
that a college degree should represent? Do colleges know how numerate
their graduates are? Do they care?
IÕm tempted to say that I have no standing to answer this question, but I
think that higher education is in even worse shape than K-12, to the
extent that the degree or diploma is meaningless except as a measure of
persistence. ItÕs hard to imagine a major in which some quantitative
literacy isnÕt necessary, in context, but the colleges that I know about
that keep track do so entirely out of context, so math is another filter
and a bad representation of math, at that. The California State
University ELM exam (I think that stands for Elementary Level
Mathematics, but am not sure) is a particularly pernicious test of out-
of-context, who cares stuff. So, I donÕt think that thereÕs consensus
and in the current political climate IÕd be afraid to see what that
consensus would look like. (The UC/CSU Math Diagnostic Test is another
favorite, though I have heard that it now has constructed response items
and doesnÕt classify students on the basis of their ability to add
fractions with unlike denominators, which was the pivotal item for
getting placed into calculus.)
Many public universities (e.g., CUNY) have come under attack for the
extent of remedial work offered to undergraduate students. Indeed, on
many campuses the entire QL effort is devoted to helping students
overcome deficiencies in preparation for college. Should numeracy
represent more than remediation? If so, how much more?
This goes to the definition of numeracy. If itÕs the traditional one,
then the colleges have a huge task at getting students to be numerate in
context. The business about remedial work is a budget matter, I think.
Who pays for the failure of K-12? Why donÕt we send them to community
college, which is cheaper, etc.
This question reminds me of something that I may have told you and is
somewhat tangential, but itÕs a story that I like. Smith College (my
alma mater, from the previous story) has a Five College calculus reform
model, spearheaded by Jim Callahan, one of the professors of mathematics
from whom I learned mathematics but didnÕt take courses. He told me that
they had had to develop a one-semester course for students who entered
with 5Õs on the BC calculus AP exam which helped them to connect the
calculus that they had studied to the contexts in which Smith freshman
had learned it--economic, social, etc. I loved it! He was discouraged
about other faculty being willing to take up the reform ideas, but I
thought that the need for such a course was wonderful.
IÕm obviously running out of steam, but you said that you wanted a 7-10
day turn on these questions, so I think that I should sign off for
tonight. I hope that I have given you enough grist for the mill of
another round! Or, I need feedback about how useful or not useful my
replies so far have been.

Peggy Skinner: So, with that introduction, let me give a few thoughts to
you. It is interesting that I recently was on a hiring committee for
Bush to add an upper school math teacher. My questions in every
interview included a basic one about the nature of a quantitative
literate individual. What does a student need to be literate in math? I
asked. (only one person out of 8 had thought about that issue before
coming to the interview). I followed that a series of questions about
conversations that they had had with science teachers to attempt to make
math usable outside of the math classroom. We do a national search for
our positions at Bush and interviewed about 8 of the best candidates.
Only one of the 8 addressed the question of literacy.
With reference to your specific questions:
