5
Seeing 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

6
Sample Question Consider the 2 and 3 pictured
below. Which is the bigger numeral? Which is the
bigger number?
7
Other Memorable Texts
  • School Mathematics Study Group (Allen, Frank, at
    al.). Geometry with Coordinates, Parts I and II.
    Yale University Press, 1962.

8
Geometry 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.

9
Geometry 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
    ____.

10
Renowned 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.

11
Allendoerfer 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.

12
Allendoerfer
  • 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.

13
Fundamentals 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

14
The 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

15
Allendoerfers 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

17
New 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.

18
More 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.

19
Klines 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.

20
More 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.

21
Yet 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.

22
And 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.

23
1970sYears of Issues and Some Direction
  • January 5 - First episode of All My Children
    January 16 - Buckminster Fuller recognized by
    American Institute of Architects.
  • March 17 - My Lai massacre charges
  • April 1 - President Nixon signs the Public Health
    Cigarette Smoking Act into law banning cigarette
    television advertisements
  • May 4 - Kent State shootings
  • October 26 Doonesbury debuts.

24
What 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.

25
What 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?

26
Motion 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.

27
1980s
  • Introduction of the IBM PC in 1981.
  • First commercial hand-held mobile phone 1983.
  • Apple Macintosh first successfully commercially
    released in 1984.
  • Space Shuttle Challenger disaster in 1986.
  • Gorbachev introduces Glasnost and Perestroika in
    the Soviet Union.
  • Soviet Union ends its military campaign in
    Afghanistan.
  • Ronald Reagan decides to invade Grenada in 1984.
  • Rubiks cube, Cabbage Patch Kids and Trivial
    Pursuit entertain us.
  • Popular artists include Michael Jackson, Bon
    Jovi, Duran Duran Madonna, U2, and Menudo.
  • Steven Spielbergs E.T. The Extra-Terrestrial
    opens in 1982.
  • AIDS epidemic is identified and named.

28
1980s
  • Preparation for change culminating with the
    publication of Curriculum and Evaluation
    Standards for School Mathematics by NCTM in 1989.

29
From 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)

30
Jack 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
31
John 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.

32
Of 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.

33
Of 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.

34
1990s characterized by conflict and change in
mathematics.
  • NCTM
  • publishes Assessment Standards and Professional
    Teaching Standards.
  • creates Teaching Children Mathematics,
    Mathematics Teaching in the Middle School,
    Dialogues.

35

  • Technology oriented

37
Example Test Item from SIMMS Integrated
Mathematics with Technology
  • According to a newspaper report, the trees in a
    certain land area are being cut at a rate of 15
    a year. The lumber company claims that it
    replaces 2000 trees every year in the area.
    Discuss the future tree production of this land
    area if the plan continues.
