Investigations Math Poll Results  Math Program Comparison
Below you will find a sidebyside comparison of Investigations Math and Saxon
Math's philosophy and curriculum. I am thoroughly satisfied that Investigations
Math is an inferior product when compared to other programs. The
school district touts studies used to show how great this program is, but
if you examine
the articles on the prior page you'll find those studies torn apart as works
of people that didn't follow the scientific method in their research. Read
what the Harvard professor had to say about the program and you'll wonder what
kind of research our school board did or if the allegation of kickbacks (Q10
page) might be true.
Traditional math is the type
of math
most of
us
grew up with and it's been sufficient in the past to produce good math students.
Traditional math focuses on a topic
or chapter
of
study,
has the students learn and practice it, then moves on. It is sometimes
up to the individual
to gleen what relationships that unit of study has with other units of study,
unless they have a good teacher that guides them in their comprehension of
such things. There is nothing wrong with the traditional method, but newer
methods have been developed to see if there is a better way to teach.
Saxon math operates more along
the lines of traditional math by focusing on math facts and "how to" do
it, rather than an exploration at early ages in understanding numbers. The
difference between Saxon and "traditional" is that Saxon takes
a study topic and never leaves it alone. In other words, when you move on
to
a new
topic,
the old topics are incorporated directly into the new topic so retention
is greatly improved and math facts are taken in incremental chunks. Please
read the brief
overview below for additional information on this.
The information I have put below comes from websites and information provided
to me by the head of the school district's Investigations Math program.
One topic in particular settled the whole debate for
me: Saxon math's 2nd grade curriculum says students will master multiplication
facts to 5 and the
3rd
grade curriculum says, "master all basic addition, subtraction,
multiplication, and division facts." Investigations NEVER has students
master these facts. In addition to this side by side comparison, check out
Singapore
Math's curriculum which has students starting the basics of multiplication
in 1st grade!
Investigations Math (from
site ) 

Brief Overview 
The Investigations curriculum embodies a different approach from the traditional
textbookbased curriculum. It is designed to invite all students into mathematicsgirls
and boys, diverse cultural, ethnic, and language groups, and students with
different strengths and interests. Problem contexts often call on students
to share experiences from their families, culture, or community. The following
aspects of the curriculum ensure that all students are included in significant
mathematical learning.
Students:
 spend more time exploring problems in depth
 find more than one solution
to many problems they work on
 invent
their own strategies and approaches, rather than relying
on memorized procedures
 choose from a variety of concrete materials
and appropriate technology, including calculators as a natural
part of their
everyday mathematical
work
 express their mathematical thinking through drawing, writing,
and talking
 work in a variety of groupings such as a whole
class, individually, in pairs, and in small groups
 move around
in the classroom as they explore the mathematics in their environment
and talk with their peers
Investigations in Number, Data and Space looks and feels quite different
from a traditional mathematics program. The curriculum at each grade level
is organized into units. Each unit offers two to eight weeks of mathematics
work on topics in number, data analysis, and geometry and consists of a
series of investigations that involve students in the exploration of major
mathematical ideas. Because of the many interconnections among mathematical
ideas, units may revolve around two or three related areas—for example,
addition and subtraction or geometry and fractions.

The Saxon Difference: Our Approach to Math Instruction
Saxon Math is the only major math program on the market today that systematically
distributes instruction and practice and assessment throughout the academic
year as opposed to concentrating, or massing, the instruction, practice
and assessment of related concepts into a short period of time  usually
within a unit or chapter. Saxon Math 's unique approach to math instruction
ensures that students not only gain but also retain essential math skills.
The pedagogy used in Saxon Math is unique, effective and researchbased.
The authors of Saxon Math began developing the series by first breaking
complex concepts into related increments, recognizing that smaller pieces
of information are easier to teach and easier to learn. Then they systematically
distributed the instruction, practice and assessment of those increments
across a grade level. Wellestablished research has shown that this spaced
(distributed) approach has produced significantly higher levels of student
learning than massed presentations such as those found in programs with
a chapterbased approach (Dempster & Farris, 1990).
Incremental Instruction Distributed Across the Level
In Saxon Math , each increment builds on the foundation of earlier increments,
leading students to a deeper understanding of mathematical concepts. The
instruction of related increments is carefully distributed throughout the
grade level, ensuring that students have the opportunity to master each
increment before being introduced to the next related one. Foundational
research has shown that instruction that presents material to be learned
over several intervals (distributed instruction) results in greater student
achievement than instruction that is not distributed (English, Wellburn & Killian,
1934). Further studies have confirmed that distributed instruction is more
effective in a variety of subjects including mathematics (Dempster, 1988;
Hintzman, 1974; Reynolds & Glasser, 1964).
Continual Practice Distributed Across the Level
Practice of an increment is distributed continually across each grade
level. Continual, distributed practice ensures that concepts are committed
to students' longterm memory and that students achieve automaticity of
basic math skills. Several research studies show that students who are
taught with a mathematics curriculum that uses continual practice and review
show greater skill acquisition and math achievement (Good & Grouws,
1979; MacDonald, 1984; Hardesty, 1986; Mayfield & Chase, 2002; Usnick,
1991; Ornstein, 1990). Additional studies have concluded that spaced (distributed)
practice results in higher performance than massed practice (Dhaliwal,
1987; Proctor, 1980).
Cumulative Assessment Distributed Across the Level
The frequent, cumulative assessments in Saxon Math assess both the acquisition
and maintenance of concepts. Assessments are built into each fifth lesson
to help teachers frequently gauge students' progress. And, since each of
the assessments is cumulative, teachers can also monitor students' retention
of skills. The Saxon Math assessment strategies are based on foundational
research showing that effective assessment is frequent and cumulative rather
than infrequent or related only to content covered since the last test
(Dempster, 1991).
