Preface
Purpose of This Monograph
We live in a time of great change in
mathematics education. The National Council of Teachers of
Mathematics (NCTM) Standards and other influential reports have
called for radical reform in U.S. school mathematics in order
to prepare all students to meet the mathematical demands
of today’s society (NCTM, 1989, 1991, 1995, 2000;
National Research Council [NRC], 1989; U.S. Department of
Education, 1996). These reports challenge the content and
pedagogy of current mathematics instruction. Most importantly,
they highlight the need for more student-centered and
constructivist-based instruction so that problem-solving,
meaning-making and conceptual understanding are emphasized, not
rote memorization of facts and procedures.
This new focus departs radically from the
way mathematics has traditionally been taught. Putting the
reports’ recommendations into practice will require
teachers to rethink not only their teaching practices but also
the very goals of teaching mathematics. Schools and districts
will also have to revise their mathematics curricula and
assessments and work together to redefine expectations for
students’ learning and teaching practices. These changes
are not easy to accomplish; they demand not only supportive
school structures but also high quality professional
development programs to guide and support teachers’
individual and collaborative efforts.
Such professional development programs
present a new challenge for providers and consumers. As
principal investigators of a few NSF-funded professional
development projects in mathematics, we have learned that
neither typical university courses nor traditional in-service
workshops go far enough. Different kinds of experiences are
needed if we wish to promote radically different beliefs and
practices and create learning communities engaged in reform.
Fortunately, several examples of
successful professional development initiatives that support
school mathematics reform have emerged in the last twenty years
(as reported, for example, in Friel & Bright [1997] and
Eisenhower National Clearinghouse for Mathematics and Science
Education [ENC] [2000]). These initiatives include not only a
new set of goals and principles but also new kinds of
professional development activities, such as innovative
mathematical learning experiences for teachers, in-depth
examinations of students’ mathematical work, “case
discussions” and various kinds of supported field
experiences.
The main purpose of this monograph is to
identify and critically examine these promising professional
development practices, with the goal of enabling professional
development providers and users to better evaluate how each can
best be used to support school mathematics reform.
Because systematic research studies on
effective mathematics teacher education are still limited, many
questions about teacher change, school reform, and the effects
of specific professional development strategies remain
unanswered. At the same time, some theories and empirical data
are emerging that may help providers and users evaluate the
potential contributions of alternative professional development
initiatives. In this monograph, we will synthesize and critique
these theoretical and empirical contributions by looking at
both the published literature and the “informal
knowledge” shared among successful practitioners. As a
main source for the latter, we draw primarily upon the results
reported by the many Teacher Enhancement and Local Systemic
Change projects funded by the National Science Foundation
during the last twenty years.
We hope that the monograph will be useful
for those who design and facilitate professional development
for mathematics teachers of all
grade levels. Even more
importantly, however, our goal is to support informed decisions
on the part of a wide range of education professionals who are consumers of
professional development. Consumers include school
administrators who make decisions about the kind of
professional development that should take place in their
district, teachers who must choose professional development
initiatives to participate in, and officials at government
agencies and private foundations who fund teacher enhancement
projects.
Assumptions informing this monograph
Before embarking on an in-depth analysis
of specific professional development practices, we want to
clarify some assumptions that inform our perspective.
Along with Susan Loucks-Horsley and her
colleagues (1998), we believe that good professional
development programs result from knowing the unique goals,
needs and constraints of each audience:
Professional development, like teaching,
is about decision making – designing optimal
opportunities tailored to the unique situation.
(Loucks-Horsley, Hewson, Love &
Stiles, 1998, p. xiii)
Thus, if professional development is
audience-based, no single model of professional development
will work for all. Rather, content, format and activities
should be considered in light of each situation to determine
which would be most appropriate and effective, and in which
combination and sequence. At the same time, knowing about a
variety of practices and their potential contributions to
achieving specific goals will be critical to making informed
decisions.
To accomplish this end, we suggest that
professional development providers and consumers should know
about, and take into consideration, the following elements:
The
needs of teachers engaging in school mathematics reform and how
these needs may be effectively addressed,
The
principles informing the most successful professional
development initiatives and the theoretical and empirical basis
of those principles, and
The
strengths and limitations of different types of professional
development activities that have been successfully developed
and field-tested by the mathematics teacher education
community.
We have created this monograph to help
readers gain this knowledge base.
We are aware that there are other key
logistical issues that professional development providers need
to address, such as scheduling initiatives, organizing the
space for them, grouping participants, and offering
compensation or other incentives for participants, just to name
a few. While we recognize that these issues are critical to the
success of any professional development initiative, they are
beyond the scope of this monograph.
How the monograph is organized
The next three chapters of the monograph
are devoted to developing a framework to evaluate specific
professional development initiatives and practices.
To this end, in Chapter 1 we examine what
teachers may need in order to successfully engage in school
mathematics reform. Based on what we have learned about teacher
development and reform from research and exemplary practice, we
identify and discuss nine categories of “teacher learning
needs” that should be addressed by professional
development that aims at supporting instructional innovation in
mathematics.
Chapter 2 provides some images of
effective professional development. Here we portray two of the
several professional development programs in the literature
that have documented success in supporting school mathematics
reform. We selected these examples to illustrate significantly
different approaches that can be used to address the teacher
learning needs identified in Chapter 1 at different grade
levels. We hope these descriptions will reveal the complexity
of good professional development programs and show the many
alternatives available.
In Chapter 3, we compare the programs
described in Chapter 2 to identify both elements that are
shared by most effective professional development programs and
some options consumers and providers can choose from. Among
these options, we identify the various formats that
professional development can take on, the possible areas of expertise for professional development providers and, most
importantly, a few categories of professional development experiences that represent quite different yet
complementary approaches to address the needs of mathematics
teachers engaging in reform.
In Chapters 4 to 8 we then examine in
depth each of these types of
professional development
experiences, which we have characterized as engaging teachers
in:
Experiences-as-learners
where they experience first-hand some innovative ways to learn
and teach mathematics (Chapter 4).
In-depth
analysis of students’ mathematical work (Chapter 5).
“Case
discussions” where a selected example of practice serves
as the catalyst for reflecting on and discussing important
issues related to school mathematics reform (Chapter 6).
Structured
and scaffolded attempts at instructional innovation (Chapter
7).
Gathering
and making sense of relevant information about various aspects
of school mathematics reform, using a variety of tools (Chapter
8).
In each of these chapters, we use the
framework developed in the first part of the monograph to
examine what characterizes professional development activities
within that given category, and how and why these activities
can contribute to support teachers engaged in school
mathematics reform. More specifically, we begin by discussing
the theoretical rationale
and empirical evidence that
support the featured type of professional development
experience. Next, we provide two illustrations
to give a rich image of this type of experience in action,
while also showing the many differences that could occur in its
implementation. Referring to these examples, we then articulate
the characteristic
elements of this type of
professional development experience and discuss some of its main variations. We follow this with an analysis of how each of the teacher learning needs identified in Chapter 1 can be addressed
by variations within this kind of professional development
experience (further summarized in Figure 11 in our concluding
chapter). Each chapter concludes with suggestions for follow-up
readings.
The monograph closes with
a summary chapter in which we briefly review our major findings about
what kinds of professional development can best support school mathematics
reform. We also provide some suggestions about how providers and consumers
can ensure that mathematics teachers are offered the high quality professional
development they need to significantly improve mathematics instruction.
