5Seeing Through Mathematics-Book 2, Scott Foresman
- Written by Henry Van Engen, et al.
- Reviewed in December 1965 Mathematics Teacher (R.
M. Shelton, Milliken University) - Authors goal Make sure that students learn all
of the mathematics customarily in the first
course in high school algebra - Activities developed with concrete materials
- General case reached through well-developed
questions - Student develops major ideas of the topic for
himself - Student has to do a considerable amount of
thoughtful reading and this should help to
develop good habits for reading mathematics books
at higher levels - Authors use mathematical terms properly without
being overly fussy - Exercises are adequate
- I have not had an opportunity to use this book
6Sample Question Consider the 2 and 3 pictured
below. Which is the bigger numeral? Which is the
bigger number?
7Other Memorable Texts
- School Mathematics Study Group (Allen, Frank, at
al.). Geometry with Coordinates, Parts I and II.
Yale University Press, 1962.
8Geometry with Coordinates, School Mathematics
Study Group, 1962
- The School Mathematics Study Group (SMSG) began
work in 1950s and had material on the land by
1960 in limited use. - This was a part of the revolution in mathematics
following the launching of Sputnik by the USSR.
9Geometry with Coordinates, Part I, School
Mathematics Study Group
- Examples
- The absolute value of the difference between the
lengths of any two sides of a triangle is
(greater than, equal to, less than) the length of
the third side. - If the lengths of two sides of a triangle are 8
and 12, the length of the third side of the
triangle must be greater than ___ and less than
____.
10Renowned mathematician Carl Allendoerfer wrote
in the Mathematics Teacher (December, 1965),
- The first versions of the SMSG materials were
generally released in revised form for use in
1960. So now we have had five years of experience
with them and can begin to form judgments of
their effectiveness.
11Allendoerfer continued,
- history makes it clear that the SMSG materials
were generally aimed at college-capable students.
It was recognized that there were other students
in the schools, and some people expressed pious
hopes that with some simplification the SMSG
materials could be made useful for them as well.
I have seen no sign, however, that this was ever
pressed very hard.
12Allendoerfer
- In 1963, the College Board published data from
181 schools that normally sent students to take
the College Board Mathematics Achievement Tests. - 28 did not teach the structure of the number
system - 34 did not teach set theory
- 56 did not teach logic
- 30 did not teach probability
- 30 gave no attention to calculus.
13Fundamentals of Freshman Mathematics by
Allendoerfer and Oakley
- When you study any new subject, your first task
is to learn the meanings of the special,
technical terms which are introduced. p. 2
14The Cambridge Report of 1963
- The authors succumbed to euphoria.
- They thought that two years of calculus could be
taught in high school. - The report shows no knowledge of the work of
psychologists on how children learn. - The report ignores the lower 7/8 of the ability
group. These children include the culturally
deprived and those who are likely to be the poor
of the next generation. - Allendoerfer
15Allendoerfers Proposed Interim Solution when the
Cambridge recommendations cannot be met.
- Adopt the scheme of having arithmetic taught by
arithmetic specialists. - Put more emphasis on remedial work in arithmetic
in high schools for those who need it. - Overcome the mathematical blocks that exist in
young people - Teach them from scratch
16- 1966--June 2-Surveryor 1 lands on the moon
becoming the first to soft land on another world - June 5-Gene Cernan completes 2nd U.S. spacewalk
on the Gemini 9 mission. - June 6-James Meredith, civil right activist is
shot while trying to march across Mississippi. - June 13-The U.S. Supreme Court rules in Miranda
vs. Arizona that police must inform suspects of
their rights before questioning them. - June 14-The Vatican announces the abolition of
Index Liborum Prohibitum index of banned books. - June 29-U.S. planes begin bombing Hanoi and
Haiphong. - Johnny survived one year of teaching and taught
summer school for the one and only time in high
schools. - August 1966-Johnny starts a masters program at
Emory University to learn all the math that he
did not know in his textbooks in 1965-6
17New Math in full swing
- Critics
- Morris Kline (April, 1966)
- Principles of modern mathematics curricula
- Mathematics is or should be presented as a set
of deductive structures. - Mathematics is to be presented rigorously.
- Mathematics is built up as an isolated,
self-sufficient, pure body of knowledge.
18More Kline
- Mathematics is self-generating axioms,
concepts, and theorems come from purely
mathematical sources. - Students learn purely abstract concepts and if
they learn these, the concrete will be
automatically understood. - The more terminology the better.
- Never use words where symbols can be
substituted.
19Klines Proposal Principles
- Mathematics must be developed, not deductively
but constructively. - Mathematics must be presented as intuitively as
possible. - Mathematics is not an isolated, self-sufficient
body of knowledge. It exists to help man
understand and master the physical, economic and
social worlds.
20More Kline Principles
- Elementary math is not self-generating
significant math grew out of real situations,
needs, problems and phenomena. - Math must be presented concretely.
- Math must use as few terms as possible.
21Yet more Klineon algebra
- The ninth year is the crucial year. It is the
students first real experience with mathematics
The content of ninth-grade algebra that I would
recommend is the traditional one.
22And more Klineon geometry
- the essential new feature is the approach.
- Dont start with a string of definitions.
- Use no more than 10 axioms.
- Add the topic of conic sections.
- Teach how proofs come from physical facts using
location of buildings, astronomy problems,
inclined plane, mass of the earth and more
homely applications.
231970sYears of Issues and Some Direction

24What is happening in the classroom?
- Should mathematical logic be taught formally in
mathematics classes? (con-Peter Hilton) - Should performance contracting exist in math?
(con-Tom Cooney and Larry Hatfield - Eliminate frills taxpayers disenchanted.
- Should math use behavioral objectives?
(pro-Allendoerfer con-Forbes) - Understanding, appreciating, etc. can only be
deduced from observed behavior.
25What is happening in the classroom?
- What should become of the high school geometry
course? (Fehr, Eccles, and Meserve) - Has the time for accountability come? (Wells and
Willoughby) - Should instruction be individualized?
26Motion Geometry?
- UICSM (University of Illinois Committee on School
Mathematics) introduced four paperback geometry
books for middle school students in the 60s. - Only in the 1970s was the first high school
transformational geometry book published.
271980s

Jovi, Duran Duran Madonna, U2, and Menudo. - Steven Spielbergs E.T. The Extra-Terrestrial
opens in 1982. - AIDS epidemic is identified and named.
281980s
- Preparation for change culminating with the
publication of Curriculum and Evaluation
Standards for School Mathematics by NCTM in 1989.
29From the Arithmetic Teacher
- The fundamental problem with arithmetic is to
find effective computational techniques for
coping with the usual array of arithmetic
situations that are encountered in real life.
Madell, AT, (October 1987)
30Jack drew a sketch of a lot as shown. To fence
the lot, the cost is 12.75 a rod. How much will
the fence cost if 16.5 ft 1 rod?
99 ft
132 ft
31John Newton writes,
- Pattern blocks are a natural medium for
stimulating spatial and geometric thinking...With
Logo, those same ideas can appear in bright
colors on a computer screen or printout.
32Of the 1980s, Stephen Willoughby writes,
- Many circumstances inhibit meaningful change
- Lack of teacher time to evaluate texts and
prepare to teach new materials. - 2. Tradition of adopting K-8 series prevents
upper-grade texts from being more advanced.
33Of the 1980s, Stephen Willoughby writes,
- 3. Adopting best sellers instead of carefully
developed, innovative, field-tested programs that
have been proven effective and that integrate all
important strands, including problem solving,
thinking, and communication is a bad thing by
penny-wise cost cutters. - 4. Minimal-competency tests are indeed minimizing
competency.
