A Report to the CUPM
From the
Quantitative Literacy and
Service Course Subcommittees
On the curriculum for
students in non-mathematically intensive disciplines
The
vast majority of students attending college today are studying in disciplines
that are not mathematically intensive. In fact, the majority of students in
most college mathematics departments are majoring in disciplines that are not
mathematically intensive. However, these
students, as college-educated individuals, still deserve at least a minimal
competency in quantitative reasoning to go along with their competencies in
writing and speaking. The foundation for the acquisition of such competencies
should begin early in the student's college career and be reinforced throughout
the student's undergraduate program.
In today's world quantitative reasoning is essential for evaluating concerns in every sector of life--the community, the state, and the nation. The analysis of problem settings and problem solving is expected of our leaders, but it often involves quantitative components. Further, such situations are also a part of personal decision-making. In fact, the primary reason for colleges and universities to require that these students take some mathematics should be to address the students' need to be educated at a level in quantitative reasoning commensurate with a college educated mind, and that are expected of individuals in today's highly quantitative society. A secondary reason for requiring some mathematics for these students is to provide them with more appreciation for the role of mathematics and quantitative skills in society.
Mathematics departments must seriously
consider the needs of these students because of the the skills that they are
expected to have to be successful in our society, the attitudes many have
towards mathematics, number of students involved, and their lost potential (and
possibly that of their children) as students mathematics, science, engineering
and technology.
This
report will speak to the needs of those students majoring in disciplines that
are not mathematically intensive, with the one exception of students majoring
in elementary education. The latter have
very special mathematical needs and those needs should be discussed in a
separate report.
The
students whose needs are described in this document are those who currently
take only one mathematics course in college.
Their rationale might be to satisfy a minimum competency in mathematics
or to satisfy a prerequisite for study in general education science courses and
applied statistics course taught outside the mathematics department. A few may actually take a general mathematics
course to learn how a mathematician or statistician thinks or develops his/her
ideas.
The
MAA's Quantitative Reasoning Report of 1995 establishes mathematical and
quantitative goals for these students.
That report justified the following five goals:
1.
Interpret mathematical models such as formulas, graphs, tables, and
schematics, and draw inferences from them.
2.
Represent mathematical information symbolically, visually, numerically,
and verbally.
3.
Use arithmetical, algebraic, geometric and statistical methods to solve
problems.
4.
Estimate and check answers to mathematical problems in order to
determine reasonableness, identify alternatives, and select optimal results.
5.
Recognize that mathematical and statistical methods have limits.
The
report "Mathematics and Democracy: The Case for Quantitative
Literacy" just published by the National Council on Education and the
Disciplines re-iterates the importance of these goals for all of our students.
In
addition, the NCED report clearly draws the distinction between mathematical
study which asks students to climb the ladder of abstraction, to rise above
context, and is about general principles and quantitative literacy which asks
students to stay in context, to see context through a quantitative lens, and to
use simple mathematics in complex situations.
This
distinction informs the belief of this committee that most students have been
ill-served by the traditional college algebra course which was - and
fundamentally continues to be - designed to prepare students to eventually take
calculus. The quantitative literacy needs of students who do not intend to, nor
are expected to, study calculus are ill-served by courses with that goal in
mind. In particular, pre-calculus
courses are designed with the assumption that they are not terminal mathematics
courses. Further, the pre-calculus
courses frequently omit a wide range of topics and forms of quantitative
reasoning that will be confronted by a college-educated individual.
Current
controversy concerning what should or should not be labelled "college
algebra" does little to answer the real issues at hand--namely, what
should be preparatory today as knowledge and technical skills for the study of
calculus, and how should this prerequisite material be taught and intertwined
with the quantitative literacy needs for those students
intending
to take calculus.
Therefore
the most significant recommendation of this report is
Recommendation
One: Each
mathematics department should encourage and support their college or university
in establishing a quantitative literacy program for all students. This program should pay particular attention
to the needs of students not studying in mathematically intensive fields. A typical program may consist of a foundation
course offered by the mathematics department (covering topics to be identified
below), and subsequent courses with quantitative components offered by many
disciplines.
In fact, because many students who begin a
pre-calculus program of study eventually do not actually take calculus, these
programs must also pay attention to the quantitative literacy needs of the
students, while not losing sight of their primary goal. The topics from
algebra, trigonometry and elementary study of functions should be carefully
delineated and taught in new ways, including significant use of concepts in
"word problem" situations to contextualize the learning. The next significant recommendation of this
report is therefore
Recommendation
Two: A new
preparatory course, or courses, should be developed for those intending to, or
expected to, take calculus. Careful attention should be paid to the course
titles given to this course. In
particular, "college algebra" should not be used as a catch-all title
for all pre-calculus courses.
This
committee further notes that many students entering college are not prepared to
begin working towards either of these curriculum goals (calculus or
quantitative literacy) without significant assistance. Therefore, we have a final recommendation.
Recommendation Three: Institutions should develop
a well-structured developmental mathematics program to prepare students for
collegiate level work in both mathematical and quantitative reasoning.
While
much of the work in these developmental courses will cover topics included in
pre-algebra and algebra, careful attention should be given to the fact that the
primary goal of these courses is to help the students be successful in wide
variety of settings, particularly in applied contexts arising in general
education courses outside of the mathematics department. This suggests that the general pedagogical
structure of such courses should emphasis quantitative literacy rather than
computational proficiency.
The
following additional recommendations are organized around the working group
topics proposed by the CUPM. They speak
to issues of concern for students majoring in non-mathematically intensive
disciplines and who may only take one course from the mathematics department.
Mathematical
Ideas and Themes
A1
- To achieve some level of quantitative literacy, all students at a college or
university should have exposure and experience with a diverse set of
mathematical ideas. There is some
consensus that this set of ideas should include, at a minimum, elementary
probability and descriptive statistics, estimation and approximation, interest
and finance, developing and utilizing linear and exponential models, and
problem-solving.
A5
- For students in disciplines that are not mathematically intensive it is of
less importance that they understand that mathematics is "an engaging
field with contemporary open questions" than it is to understand that mathematics
can actually be used to solve the problems that they currently face, and will
have to face in their lives. This does
not imply, however, that mathematics should be taught as a bag of prescribed
tools for solving standard, previously described problems.
B1 - All students should have some mastery of
elementary facts and skills. These should include the usual arithmetic skills,
algebraic skills at the level of at least one year of high school algebra,
geometric skills and facts involving length, area, and volume for standard
figures, and statistical skills consisting of elementary probability,
presentation of data, and interpretation of statistical concepts and
tests.
Students should know what a function is and be able to provide description of functions in multiple representations and to provide descriptors of functions as increasing, decreasing, increasing faster than, etc. Students should understand the idea of linear relationships and an understanding of when relationships are not linear, and those for which a linear model will suffice as an approximation. Approximation should be more general than arithmetic and include notions such as geometrically approximating lengths by line segments, approximating areas by inscribing rectangles or circumscribing rectangles, approximating volumes by packing in cubes, etc. Further, students should understand the idea of optimization of a function.
B2 - All students should acquire the
rudiments of problem solving. This means
that students must develop an internalized resource of mathematical ideas and
facts, along with knowledge of problem solving strategies. Further, they should have sufficient
experiences working with such knowledge so as to develop the connections they
need between the mathematical facts and skills and the strategies to apply in
order to set up a problem plan for solution.
Complexity of problem solving should also be
something they understand. They should
realize the difference between a one-step problem and a problem that which can
be viewed as a multistep situation where many subproblems occur.
Students should experience problem solving in a wide variety of settings without the technicalities of work that a major in a field would experience. For example, geometric settings abound in our every day life, as do many items related to the environment, personal business, etc. In other words, working quantitatively should come naturally to students through their involvement in the many different areas that impact their lives as individuals and citizens.
B3
- Students in non-mathematically intensive fields may have intuitive skills of
visualization on which to build understanding.
These skills could include understanding the impact of color on a
presentation; the emotional impact of
the positioning of actors on a stage; or the marketing impact of the
arrangement of a window display for a retail store. Mathematics instructors should identify and
capitalize on these skills to develop better visualization skills in
quantitative contexts.
Proofs
and Arguments
A2
- As stated in the general goals above, all students should be able to think
analytically and critically about information that they receive and about
problems they must solve. In particular,
students must be able to formulate problems in a real-world context, solve
them, and interpret them back to this real-world context.
A3 - While students studying in non-mathematically
intensive disciplines do not need to be experts at proof constructions, they
should be able to verbally describe the inductive and deductive reasoning
processes; should be able to distinguish between instances of inductive and
deductive argument; and should be able to produce simple inductive and
deductive arguments, as well as counterexamples. They should be able to
identify logical fallacies and be able to utilize the techniques of survey
analysis to correctly interpret data (in particular, sort out overlapping
responses when a set of questions have been asked of the same individual).
Relationship
to other Disciplines
A4
- Students should be able to build elementary mathematical models of problems
from other disciplines. Students should
be able to use elementary mathematical models when enrolled in courses from
other departments. That is, knowledge
from the mathematics classroom needs to be transferable to other contexts -
this is at the heart of quantitative literacy.
F2
- Each department should work with faculty in other disciplines to establish
course prerequisites that are based on requisite student background rather than
on course titles. In particular, a
blanket use of "college algebra" as a prerequisite doesn't guarantee
any requisite student knowledge, unless this link is very clearly articulated. Mathematics departments should work with
other disciplines to develop courses for the general student population that
provide these students with the necessary skills for success in other general
education courses.
F3
- It will generally take more than one course for students to achieve the five
quantitative literacy goals identified above, so departments must work with
other disciplines to develop quantitative experiences in courses outside of the
mathematics department that build and extend the work begun in the student's
first year experience.
Use
and understanding of technology
A6
- Students who are not majoring in mathematics intensive fields will be
expected to use technology in their workplace and homes. Therefore they should be able to demonstrate
the ability to use the graphics features of a calculator to obtain information
and should be able to demonstrate the ability to use computer based tools, such
as spreadsheets and CAS, to organize and manipulate data and formulas. The former competency presupposes that the
students can use the calculator functions of their electronic calculator.
F4
- Each department must provide a diverse set of technological supports for
instruction by its faculty. To clearly
demonstrate and teach the idea of using the right tool for solving a problem,
instructors must have the right tools available. The quantity of these tools, and the mix that
they are held in will depend on the student population (both size and quality),
and the institution's budget and mission.
Communication
A7
- All students should have the ability to read mathematical literature at least
to the level that it is presented in publications for the general public, for
example as contained in the Science News
weekly. They should be able to write
mathematically using both mathematical
notation
and non-mathematical language with a reasonable level of proficiency, as well
as be able to communicate mathematics orally.
B4 - All students should be encouraged to use quantitative reasoning as one way of looking at situations throughout their undergraduate curriculum. Thus, it is essential that faculty in the mathematics department be supportive of, and encourage, their colleagues in less mathematically intensive disciplines to be accepting, and to encourage, intensive projects which involve a quantitative approach whenever this is reasonable.
D2
- Efforts should be made to provide students the opportunity to communicate
mathematics within the context of their major area of study. This may involve reporting on the statistical
outcomes of surveys or studies; explicitly using an inductive or a deductive
argument to present or critic a view on a social, political, or economic issue;
or solve a problem in budgeting, theater set design, or office staffing.
Assessment
and Evaluation
E1
- For institutions without quantitative literacy programs in place,
establishing them may be an evolutionary process dependent on institutional
priorities, staff development, and student needs. Ongoing assessment of the program provides a
mechanism in this process for maintaining an institutional memory, for focusing
on both long range and short term goals, and for identifying the next critical
step in program development.
E2
- Because the students described in this report are from disciplines that are
not mathematically intensive, it is essential that mathematics faculty involve
colleagues from these other disciplines throughout the entire curriculum
design, implementation, and evaluation process.
Faculty from other disciplines can best help mathematics faculty to
identify the quantitative needs of their students and to provide feedback about
whether the courses offered by the mathematics department service this need
effectively.
F1
- Because of institutional admission policies and institutional goals,
mathematics departments must ultimately develop individualized quantitative
reasoning programs. Generally, these
programs will have three levels: a developmental mathematics course(s) for
students unprepared for collegiate level mathematics; a foundations course,
typically offered in the mathematics department; and a secondary quantitative
experience (building on ideas taught in the foundations course, but not
necessarily offered by the mathematics department) that allows students to add
depth to the mathematical understanding.
Recruitment,
retention, and satisfaction
D1
- It is essential that departments provide space for students to work together
both formally in the classroom, but also informally outside of class. For students outside of mathematically
intensive disciplines this means that they have access to spaces provided to
majors, but more importantly that they are encouraged to meet and to study
mathematics together in some reasonable context - whether that be the library,
the student union or the residence hall.
With
some encouragement, these students make very effective use of various
communication methods available through the internet. This may actually provide an additional means
to help the students with the writing skills.
D3
- One idea for recognizing the quantitative work of a student in a
non-mathematical discipline can be through an award recognizing "the best
presentation of quantitative information" in a written project. Candidate projects can be submitted by the
faculty sponsor of the work; this would also provide significant encouragement
to those faculty who support quantitative literacy.
D4
- The group of students being discussed in this report contain hidden potential
for the mathematics, science, engineering, and technology community. Teaching these students should not be
delegated to part-time faculty or graduate students. Full-time faculty are uniquely positioned to
identify students who have buried mathematical potential and to encourage this
potential over a period of several semesters as it blossoms.
F5
- Not only do regular faculty need to understand the extent (or lack thereof)
and nature of students personal and mathematical backgrounds in these
quantitative reasoning courses, but they should ensure that part-time faculty
and graduate students are aware of it as well.
Further, regular faculty should be responsible for helping part-time
faculty and graduate students develop a wide repetoire of teaching techniques
and approaches necessary to respond to the varied learning styles of students -
particular those who are in non-mathematically intensive fields as their
learning styles can vary greatly from that of students drawn to SMET.
G1
- While we may only convert a few of the students enrolled in our quantitative
reasoning courses into mathematics majors or majors in other mathematically
intensive disciplines, a positive - successful - experience in this course will
begin to change the public environment from which we draw our majors. Students with these positive experiences will
support decisions by younger siblings and by their own children to study in
mathematically intensive fields. They
will be the individuals who will demand change and improvement in our public
education systems.
G2
- Since minority students and women are not present in reasonable proportions
in the SMET curriculum, they are disproportionately among the students taking
one or no mathematics courses. That is,
many of them are among the students described in this report. As suggested elsewhere in this report,
mathematics departments should take the instruction of quantitative literacy
courses and general education courses seriously as they provide a significant
opportunity to attract talented individuals to SMET from among groups currently
underrepresented.
