An Introduction to MED 4185 Curriculum

Course Description
This course examines the ways in which high
school students acquire mathematical knowledge,
considers the particular mathematical knowledge
they should have at each grade level (as
articulated by the Principles and Standards of
School Mathematics), and applies this
understanding to the design of secondary
mathematics curricula. The course may also
include one or more of the following
discussion of how mathematics curricula have
evolved over time in response to developments in
cognitive science and other factors classroom
barriers to mathematical proficiency in the form
of gender, cultural, and socio-economic biases
and a comparison of American secondary
mathematics curricula with those of countries
that perform well on international tests of
student achievement.

Course Rationale
We have a problem with mathematics education in
the United States. Too many students graduate
from high school lacking the mathematical and
quantitative skills necessary for success in
higher education, the workforce, and daily
decision making. This happens despite national
awareness of the problem and years of attempts to
correct it. In this course we consider the
extent of the problem, and discuss possible
causes and solutions. Although what and how we
teach forms only part of a solution, it is the
aspect of mathematics education over which we
have the most control. Our best hope for
improving mathematics education comes from way we
organize and present our subject. In this course
we focus on organization (curriculum), while MED
4145 focuses on presentation (pedagogy). Knowledg
e of how students learn mathematics forms the
basis for effective curriculum and pedagogy. In
this course we examine the ways in which people
acquire mathematical knowledge. We then consider
the particular mathematical knowledge high school
students should obtain at each grade level, as
well as the principles that guide its sound
organization and presentation. Finally we use
our understanding of how students learn
mathematics and the knowledge they should acquire
to evaluate, improve, and develop mathematics
curricula.

Studying successful school mathematics programs
provides a source of inspiration for the design
of curriculum and pedagogy. Recent international
studies of school mathematics achievement reveal
surprising differences in mathematics curriculum
and pedagogy across countries. In this course we
consider these differences and the directions
they suggest for improvement. Ineffective
mathematics teaching and curricula contribute to
the problem of mathematics education. Some
students encounter additional barriers to
mathematical proficiency in the form of gender,
cultural, and socio-economic biases in the
classroom. Such biases arise from assumptions
about students innate mathematical talent (or
lack thereof). This course examines the
pervasive myth of ability and the effect of
teacher attitudes on student learning.

The Problem
  • Too many students graduate from high school
    lacking the mathematical and quantitative skills
    necessary for success in higher education, the
    workforce, and daily decision making.
  • Before Its Too Late contains a description of
    the problem, the rationale solving it, and a
    proposed solution.
  • This video shows the press conference at which
    this report was released.

6
  • The need for people capable of quantitative
    reasoning is not limited to the workplace.
    Mathematics and Democracy The Case for
    Quantitative Literacy describes several facets of
    daily life that require quantitative reasoning
    skills for their successful navigation. Areas
    include citizenship, culture, personal finance,
    and personal health.
  • Innumeracy documents the consequences of an
    inability reason fluently about the basic
    concepts of number and chance. Effects include
    belief in pseudoscience, impossible demands for
    risk-free guarantees in medicine, anxieties over
    personal safety, and so on.

The TIMSS Video Study investigated intended
curricula and teaching styles (reported by
teachers), as well as the actual curricula and
teaching styles (captured on video), in a
selection of classrooms in seven countries.
Comparing high-scoring TIMSS nations (such as
Japan and China) with the United States can
suggest possible explanations for the problem
with mathematics education.
25
Sources of the Problem
  • Teaching
  • Curricula
  • Facilities
  • Students
  • Families
  • Administrators
  • Society
  • and more

26
When we compare typical Japanese and American
classrooms, the difference is striking. Japanese
classrooms tend to embody ideals described by
American math education researchers, whereas
American classrooms tend not to. We should
not, however, place blame for the achievement gap
solely on American teachers. They form only part
of an intricate educational system. Its
important for us to have a big picture of the
problem so we can more clearly define the role we
can play in its solution. The Learning Gap
describes this picture for us.
27
Comparative Studies
  • The problem of math education begins with the
    mathematical preparation of elementary school
    teachers.
  • The following slides illustrate two situations in
    which elementary school teachers might find
    themselves.
  • How would you respond?

28
You are teaching division with fractions. To
make the topic meaningful for students, you would
like to present problems in a real-world context.
What would be a good context in which to set the
problem 1? ½ ?
29
One of your students comes to class very
excited. She tells you she has figured out a
theory that you never told the class. She
explains that she has discovered that as the
perimeter of a closed figure increases, the area
also increases. She shows you this picture to
prove what she is doing
Side 4 Sides 4 and 8 Perimeter
16 Perimeter 24 Area 14 Area 32 How would
you respond to this student?
30
Liping Ma posed these and similar questions to
groups of American and Chinese elementary school
teachers. She found that Chinese teachers begin
their careers with a better understanding of
elementary mathematics than their American
counterparts. Through on-the-job teacher
training, this comprehension grows into what she
calls a profound understanding of fundamental
mathematics (PUFM).
31

33
Chinese students consistently score significantly
higher than Americans on international tests of
mathematics achievement. This happens despite the
fact that Chinese teachers receive considerably
less mathematical education. In Knowing and
Teaching Elementary Mathematics, Ma suggests PUFM
(or lack thereof) as an explanation for this
paradox.
34
Other explanations for the difference in
mathematics achievement among American and Asian
students can be found in the results of five
studies summarized in The Learning Gap.
35
Explanations Based on Stereotypes
  • Japanese students are innately smarter than
    American students. (False.)
  • Japanese students are innately more docile than
    American students. (False.)
  • Japanese students engage in endless hours of rote
    memorization and drill. (False.)
  • Japanese parents stress academic skills long
    before their children begin formal schooling.
    (False.)
  • American children spend more time watching TV.
    (False.)

36
The Learning Gap provides explanations based on
careful studies. The sources of the problem of
mathematics education are as varied as they are
plentiful.
37
Teaching
Although what and how we teach forms only part of
the problem of mathematics education, it is the
aspect of the solution over which we have the
most control. Our best hope for improving
mathematics education comes from way we organize
and present our subject. In this course we focus
on organization (curriculum), while MED 4145
focuses on presentation (pedagogy).
38
Cognitive Science
Knowledge of how students learn mathematics forms
the basis for effective curriculum and pedagogy.
In this course we examine the ways in which
people acquire mathematical knowledge.

What does this say about teaching math? A
definition should follow an appropriate set of
examples, not precede them. How many times have
you squinted your eyes at a definition then
waited for the book or the instructor to provide
the examples? How much more natural would it
have been to read that definition after you had
worked through the examples?

  • A student with an instrumental understanding of
    this identity would justify it by citing the FOIL
    method.
  • A student with a relational understanding might
    justify it using the illustration below.

44
Relational vs. Instrumental Understanding PROS
  • Instrumental
  • Within its own context it is easier to understand
    (invert and multiply).
  • The rewards are more immediate (a page of correct
    answers).
  • The correct answer comes more quickly.
  • Relational
  • More adaptable to new tasks.
  • Easier to remember.
  • Can be a goal in itself (the teacher doesnt need
    to provide external rewards).
  • Organic in quality (act as agent of their its
    growth).

45
Relational vs. Instrumental Understanding CONS
Relational ?
  • Instrumental
  • Easier to forget or remember incorrectly.
  • Harder to apply a procedure learned in one
    context to another.
  • Needs to be reviewed frequently.
  • Leads to a perception of mathematics as a set of
    meaningless rules for the manipulation of
    symbols. The rules bear little relationship to
    each other or to real life.
  • Results in frustration and anxiety for a large
    proportion of students.
  • Creates innumeracy.

  • Mathematical Problem Solving
  • Learning Mathematics The Cognitive Science
    Approach to Mathematics

47
We use our understanding of how students learn
mathematics to evaluate, improve, and develop
mathematics curricula and pedagogy. In this
course we focus on curricula, but our
understanding of cognitive science should inform
pedagogical decisions as well.
48
In this course we use the Principles and
Standards for School Mathematics developed by
NCTM as a tool in evaluating mathematics
curricula.
49
National Council of Teachers of Mathematics (NCTM)
  • Provides vision, leadership, professional
    development, resources, and funding for teachers
    and their supporters.
  • World's largest mathematics education
    organization, with nearly 100,000 members.

50
Principles and Standards
  • Comprehensive and coherent set of goals for
    improving mathematics teaching and learning
  • Resource to use in examining and improving the
    quality of mathematics programs
  • Guide for the development of curriculum
    frameworks, assessments, and instructional
    materials
  • Tool to stimulate ideas and ongoing conversations
    about how best to help students

51
Principles
Describe particular features of high-quality
mathematics programs and provide guidance for
educational decisions.
  • Teaching
  • Assessment
  • Technology
  • Equity
  • Curriculum
  • Learning

52
Standards
  • Descriptions of the mathematical understanding,
    knowledge, and skills that students should
    acquire from kindergarten through grade 12
  • Content Standards explicitly describe the content
    students should learn.
  • Process Standards highlight ways of acquiring and
    using content knowledge.

53
Content Standards
  • Number and Operations
  • Measurement
  • Algebra
  • Data Analysis and Probability
  • Geometry

Process Standards
  • Problem Solving
  • Connections
  • Reasoning and Proof
  • Representation
  • Communication

54
Failure of Reform
  • The contributions made by curriculum and pedagogy
    to the problem of math education have been known
    for decades.
  • Both aspects of teaching have been regularly
    overhauled since the 1950s.
  • The consistent failure of these reforms have lead
    to the Math Wars and critiques such as Why
    Johnny Cant Add.

55
Equity
  • Successful mathematics programs embody
    equity---the principle that all students can and
    have the right to learn meaningful mathematics
    with understanding.
  • As a result of gender, cultural, and
    socio-economic biases found within mathematics
    classrooms, this right is denied to many
    students.
  • Americans tend to believe that mathematical
    ability is innate in some people and not in
    others. Many students sink to the low
    expectations of their teachers.

56
The Math Gene
  • The math gene is an innate ability for
    mathematical thought.
  • Language and math are both made possible by the
    same feature of the human brain.
  • This feature is the ability to form concepts by
    the process of abstraction, name concepts, and
    consciously manipulate them.
  • Anyone who can use language can do mathematics.
