University Studies Course Approval Proposal
Basic Skills Mathematics
The Department of Mathematics and Statistics proposes the following requirement for Basic
Skills in Mathematics at Winona State University. This was approved by the full department
on Thursday, September 21, 2000.
Basic Skills in Mathematics
Successful completion of any 100-level, 3-4 s.h., Mathematics (MATH) or Statistics (STAT)
course satisfies the Basic Skills Mathematics requirement.
At the same time, we also propose that the University Studies Subcommittee consider
adopting a change
to the Basic Skills whereby students may use courses required for their major or minor
program to satisfy
Basic Skills requirements.
If the proposed requirement above is approved, any of the following courses would be
acceptable as satisfying
the Basic Skills in Mathematics Requirement:
Math 100 Survey of Mathematics (3 s.h.)
Math 110 Finite Mathematics (3 s.h.)
Math 120 Precalculus (4 s.h.)
Math 130 Matrix Algebra (3 s.h.)
Math 140 Applied Calculus (3 s.h.)
Math 150 Math Earth/Life Sciences I (3 s.h.)
Math 155 Math Earth/Life Sciences II (3 s.h.)
Math 160 Calculus I (4 s.h.)
Math 165 Calculus II (4 s.h.)
Stat 110 Fundamentals of Statistics (3 s.h.)
Adhering to the current University Studies policy, none of the above courses would be
allowed to be listed
in other categories of the General Education Program.
All of these are existing courses, previously approved by A2C2.

Basic Skills in Mathematics
Description and Outcomes
3. Mathematics (3 S.H.)
The purpose of the Mathematics requirement in University Studies is to help students
develop an
appreciation of the uses and usefulness of mathematical models of our world, as applied in
a variety
of specific contexts. Students should complete the requirement as soon as possible,
preferably in their
first year and certainly no later than their third semester. Only approved courses offered
by the
Department of Mathematics and Statistics can be used to satisfy the University Studies
requirements
for Basic Skills in Mathematics. Each of these courses must address at least four of the
following outcomes.
These courses must include requirements and learning activities that promote students'
abilities to...
a. use logical reasoning by studying mathematical patterns and relationships;
b. use mathematical models to describe real-world phenomena and to solve real-world
problems -
as well as understand the limitations of models in making predictions
and drawing conclusions;
c. organize data, communicate the essential features of the data, and interpret the data
in a meaningful way;
d. do a critical analysis of scientific and other research;
e. extract correct information from tables and common graphical displays, such as line
graphs,
scatter plots, histograms, and frequency tables;
f. express the relationships illustrated in graphical displays and tables clearly and
correctly in
words; and/or
g. use appropriate technology to describe and solve quantitative problems.
Discussion of Basic Skills Mathematics Course Work and the Required Outcomes
In general, every mathematics, mathematics education, and statistics course addresses all
of the outcomes
(a.- g.) to some extent. From a global point of view, mathematics may be viewed as the
result of a human
desire to describe, quantify, and predict and to be able to do so with an unlimited degree
of accuracy and
precision. Put in a slightly different manner, mathematics is the natural result of people
wanting to have
methods of communication which do not allow for misinterpretation beyond a predetermined
amount of
allowable error (to include the possibility that no allowable error is desired). This is
what drove ancient
Greeks to begin the development of logic and geometry. It is what drove Galileo to the use
of measurement
and functions to communicate relationships between physical quantities. It is similarly
what drove Pascal and
Descartes to the development of coordinate geometry as a graphical means for examining
functions and data.
Newton and Leibniz, equally motivated by a need to predict, developed the calculus to
predict the motion of
planets and, by the same machinery, predict the motion of terrestrial objects due to
gravity. The quest continues
today as scientists in the field grapple with these issues of description, quantification,
and prediction as applied
to everyday problems concerned with the stock market, insurance and risk, the weather,
quantum machines,
and the teaching of mathematics, to name just a few. All of these objectives are therefore
inherent in the program
of mathematics itself.
The mathematics and statistics courses proposed herein are those which a student may
complete to satisfy the
Basic Skills in Mathematics requirement, and these courses contain a portion of this
legacy. Additionally, they
are all reasonably accessible to new, incoming students at WSU. On the other hand,
students come to WSU
with a wide range of backgrounds in mathematics. It is to be expected, then, that Basic
Skills in Mathematics
may be more meaningful to students if their course begins at a level of development that
is appropriate to their
existing mathematical background and abilities. Such is the rationale behind providing a
choice of courses, as
opposed to selecting one course, for Basic Skills in Mathematics.
In each of the course outlines, the outcomes which are predominantly addressed in that
particular course are i
dicated. A general discussion of each objective, including examples of student activities
which address these,
is now presented.
use logical reasoning by studying mathematical patterns and relationships
Students will gain experience with valid reasoning while investigating and applying
patterns, sequences,
and other relationships. For example, in attempting to conclude that a sequence of annual
population
data follows a logistic equation, students are faced with the difference between inductive
reasoning and
deductive reasoning. They learn that while inductive arguments, i.e., based upon
experiment, are all that
is possible given a finite amount of data, deductive arguments, i.e., based upon logical
reasoning, are
very powerful in examining questions of long-term growth or decline of that population.
The idea here
is that once a mathematical relationship or equation has been decided upon, perhaps as a
model for
some physical situation, then the full power of logical reasoning may be applied to
discover what
additional information must necessarily follow from adoption of that equation.
b. use mathematical models to describe real-world phenomena
and to solve real-world problems
-as well as understand the
limitations of models in making predictions and drawing conclusions;
Students will begin with a mathematical model, suggested by the results of experiment or
resulting
from processes such as linear/nonlinear regression applied to data, and use that model to
study the
predictions of the model. For example, data regarding the height versus weight of a group
of people
may be gathered. Linear regression may be applied to conclude a mathematical equation
(linear)
which relates height to weight. This may then be used to quantify what the
"average" (in some sense)
weight of a person is given their height. As the linear equation will return a weight for
any height, no
matter how large, students see that there is necessarily a limit to how the model may be
applied in
order to describe real people. They will also see the limitations in a calculation such as
"average"
via comparison of results from the model with actual data.
c. organize data, communicate the essential features of the
data, and interpret the data in a meaningful way;
Given a collection of data, students will investigate several methods of organization and
graphical display.
They will examine methods of isolating only that data which is necessary for the solution
of a certain
problem. Finally, they will learn that there are usually reasons to be cautious in the
interpretation of data
due to possible contamination of the data itself, e.g., flawed data collection
methodologies used, and
possible confounding factors not reflected in the data.
d. do a critical analysis of scientific and other
research;
Students will examine the methodologies, such as data collection and analysis of this
data, and results
reported due to the analyses used in the research literature which is accessible to them
(taking into
account background material necessary to understand the topics of such literature). They
will critique
these works for the validity of reasoning used, for the soundness of the mathematics
applied, and for
the appropriateness of the conclusions given the data collected.
e. extract correct information from tables and
common graphical displays, such as line graphs,
scatter plots,
histograms, and frequency tables;
It is a simple newspaper editor's trick to change the scale on a vertical or horizontal
axis of a graph to
fool the eye into thinking that something is increasing at an alarming rate (such as the
price of oil) or is
decreasing very slowly (such as unemployment). Also, there is another type of graph,
called an area
graph, which is sometimes used to communicate, e.g., that one magazine's readership is
double that
of its competitor, but really shows a symbol which is four times that of a smaller symbol
representing
the competitor's readership. Graphical displays communicate information very quickly, but
they can
also communicate incorrect information based upon shape, size, or some other factor.
Students will l
learn to carefully examine all parts of graphically presented data in order to draw
correct conclusions
from these.
f. express the relationships
illustrated in graphical displays and tables clearly and correctly in
words;
Once a student has gleaned the correct information from graphical or tabular presented
data, there is
the issue of communicating this in English. Converting from a very precise language,
Mathematics,
to a very imprecise language, English, is generally a difficult problem. Students must
learn to take care
language.
g. use appropriate technology to describe and
solve quantitative problems.
There are many different forms of hardware and software currently in use by those who
apply
mathematics to the solution of real-world problems. As the amount of realism in a
mathematical
model increases, so does the difficulty of calculations necessary to deduce the
predictions of that
model. Therefore, it is useful for students to gain experience with technology such as
graphing
calculators, MatLab and Mathematica software packages, and JMP statistical analysis
packages
as they apply mathematics to the analysis needed in studying applications motivated
problems that
include a greater level of realism.
The following is an example syllabus for Math 100 Survey of Mathematics. Although
course syllabi will vary
from instructor to instructor, the common elements of all syllabi will include (1) the
course description designating
the course as a general studies courses, (2) the University Studies Program outcomes for
Basic Skills in Mathematics
and where these are addressed in the course, and the (3) topics/instructional
methodologies as delineated in the
Mathematics and Statistics Department course outline.
The following is an example syllabus for Math 155 Mathematics
for the Earth and Life Sciences II.
Mathematics 155 Mathematics for the Earth and Life Sciences II
3 s.h.
Course Description: This course was developed in conjunction with the
earth and life science departments. Its main focus is a study of the mathematics of change
as it applies to the earth and life sciences. Emphasis is on the creation and analysis of
mathematical models of natural phenomena. Modeling begins with finite difference equations
and quickly progresses into continuous models, leading to a study of derivatives. A
qualitative analysis of differential equations and systems follows the study of
derivatives, and the course ends with a brief discussion of numerical schemes for
integration and the exploration of more in-depth models. This is a University Studies
course which satisfies the Basic Skills in Mathematics.
