CBMS Survey 2000
Of the 3.2 million students enrolled in mathand statistics courses :
981,000 (31%) were in remedial courses
653,000 (20%) took precalculus courses
1,321,000 (41%) placed into introductory courses
245,000 ( 8%) were enrolled in Calculus I
Current State of Mathematics
• Calculus enrollments are declining.
• Greatest growth in non-calculus based courses.
• Increased precalculus enrollments have not translated into increased calculus enrollments.
• Increased AP enrollment and success have not resulted in increased advanced math enrollment.
What Courses Are Students Taking?
Despite an 18% increase in undergraduate mathematics enrollments since 1980
• Calculus enrollments declined 13% at 4-year colleges & universities.
• Non-mainstream calculus enrollments declined 29%.
• 2-year college calculus enrollments increased 15%.
• Non-mainstream calculus enrollments declined 48%.
Four-year & University Enrollments
Since 1990, course enrollments increased in:
• Pre-calculus/Elementary Functions 46%
• College Algebra 5%
• Combined College Algebra/Trig 6%
Since 1990, course enrollments decreased in:
• Trigonometry 11%
Two-year College Enrollments
Since 1990, course enrollments increased in:
• Pre-calculus/Elementary Functions 37%
• College Algebra 13%
Since 1990, course enrollments decreased in:
• Combined College Algebra/Trig 11%
• Trigonometry 23%
College Algebra and Precalculus
Each year, about 1,000,000 students take college algebra and precalculus courses.
The focus in most of these courses is on preparing the students for calculus.
We know that only a relatively small percentage of these students ever go on to start calculus.
Some Questions
How many of these students actually ever do go on to start calculus?
How well do the ones who do go on actually do in calculus?
Some Questions
Why do the majority of these 1,000,000+ students a year take college algebra courses?
Are these students well-served by the kind of courses typically given as “college algebra”? If not, what kind of mathematics do these students really need?
Calculus and Related Enrollments
In 2000, about 676,000 students took Calculus, Differential Equations, Linear Algebra, and Discrete Mathematics
(This is up 6% from 1995)
Over the same time period, however, calculus enrollment has declined.
Calculus and Related Enrollments
In comparison, in 2000, 171,400 students took one of the two AP Calculus exams – AB or BC.
(This is up 40% from 1995)
In 2004, 225,000 students took AP Calculus exams
Reportedly, almost twice that many students take calculus in high school, but do not an AP exam.
Some Implications
Today more students take calculus in high school than in college
And, as ever more students take more mathematics, especially calculus, in high school, we should expect:
• Fewer students taking these courses in college
• The overall quality of the students who take these courses in college will decrease.
Associates Degrees in Mathematics
In 2000,
• There were 564,933 associate degrees
• Of these, 675 were in mathematics
This is one-tenth of one percent!
Bachelor’s Degrees in Mathematics
In 2000,
• There were 457,056 bachelor’s degrees
• Of these, 3,412 were in mathematics
This is seven-tenths of one percent!
Who Are the Students?
Based on the enrollment figures, the students
who take college algebra and related courses
are not going to become mathematics majors.
They are not going to be majors in any of the
mathematics intensive disciplines.
The Focus in these Courses
But most college algebra courses and certainly
all precalculus courses were designed to
prepare students for calculus and most of them
are still offered in that spirit.
Even though only a small percentage of the
students have any intention of going into
calculus!
Some Interesting Studies
Steve Dunbar has tracked over 150,000 students taking mathematics at the University of Nebraska – Lincoln for more than 15 years. He found that:• only about 10% of the students who pass college algebra ever go on to start Calculus I• virtually none of the students who pass college algebra ever go on to start Calculus III. • about 30% of the students who pass college algebra eventually start business calculus.• about 30-40% of the students who pass precalculus ever go on to start Calculus I.
Concluding Thoughts
The title of this session is:
Leaks in the Pipeline
But what is a pipeline?
Concluding Thoughts
Picture the Alaska pipeline that carries oil
from Prudhoe Bay to Valdez.
Every drop of oil lost en route is a valuable
commodity that is, at best, a complete loss,
and at worst, a potential threat to the
environment.
Concluding Thoughts
Do we really want to view the roughly 1,000,000
students who take college algebra courses each
year and do not end up majoring in one of the
SMET fields as a complete loss?
Maybe the pipeline metaphor has outlived its
usefulness!
Concluding Thoughts
The pipeline metaphor causes us to apply a
very negative psychological image to the
overwhelming majority of our students.
In turn, it leads many of us to think of the
courses we offer to these students as second-
class courses for students who are not
important to the mathematical enterprise.
Concluding Thoughts
The students who “leak out” are not losses.
They are simply going into other fields that
require less math or even different math.
The overwhelming majority of our students are
not “losses”.
The courses we offer should them not be thought
of as second-class courses for students who are
not important to the mathematical enterprise.
A Better Metaphor
Picture a river, particular one in the southwest.
Very little of the water from the headwaters ever reach its end; many of these rivers eventually peter out and all that remains are dry stream beds.
But the water that doesn’t make it all the way downstream is diverted to irrigate huge areas and has been used to bring the desert to life.
A Better Metaphor
What a wonderful metaphor for how we should view our students.
Those who only take college algebra or statistics or finite mathematics should not be thought of as losses; they should be thought of as valuable commodities who, with the right emphases in these courses, can irrigate all these other fields and enrich them by bringing the value of mathematics to bear.
