Chapter 2
For and Against Mathematics
Previous: Chapter 1, Introduction
Motivations from philosophy, daily life and science or technology or
business can be offered for the study of mathematics. They are described
next with some links to reason. This chapter ends with paragraphs which
discusses why students avoid mathematics.
1. For some past philosophers and thinkers, the definitions and
conclusion reaching methods in Euclid's books on geometry provided the most
certain model for rule-based reason, or how to argue if you must. Geometric
knowledge was based on rules, patterns and definitions which seemed self-evident
once said or described. Euclid's books or elements were composed two thousand
years ago. Modern translations of them exist. The translations are recommended
to specialists in geometry only, as today newer presentations of geometry and
other ideas of mathematics are favoured in the classroom. For students wanting
to understand whatever they may be doing, if not why, the Euclidean organization
of mathematical disciplines can be attractive. This is a link to the love of
rule-based reason, if not knowledge.
2. For the person in the street a few centuries ago, writing, reading and
figuring skills were signs of knowledge or education. Before the seventeenth
century A.D., if not later, the absence of a good notation for arithmetic
made figuring hard, except perhaps in areas where the abacus was readily
available. Since the seventeenth century the development of the printing
press and of arithmetic based on decimal notation, the skills of writing,
reading and figuring have become common. For the person in the street, these
skills are useful in correspondence and in the buying and selling of goods,
property and services. Counting, decimal arithmetic and the use of simple
formulas provide people with repeatable and therefore verifiable rules for
arriving at conclusions. Figuring on paper or in the head is also part of
rule-based thought and reason. This link to rule-based reason needs to be
remembered.
3. The decision of what or how to calculate in business, science and
technology often depends on an algebraic way of writing and thinking for
describing (or changing) calculations, numbers and quantities. The latter
appears as a reasoning tool. But this tool is part of the mystery surrounding
mathematics and reason for many people in school and out. Implication rules with
the algebraic way of writing and thinking, if clearly explained, provide a
foundation for both mathematical thought and also rule-based reason in all
disciplines. A student may be encouraged to study mathematics in the hope of
understanding whatever he or she might be doing and why, and to have the option
of mastering numerical disciplines in science, technology or commerce. For
better or worse, this is a link to rule-based reason in modern life.
At least four further motivations for studying mathematics exist. First,
teachers and writers in all disciplines may have the goal of identifying and
imparting some worthwhile knowledge - an incentive for this writer. Second,
researchers in mathematics may identify the goal of extending the boundaries and
form of mathematical thought. Third, some people were attracted to mathematics
instruction and research just as a means to a livelihood in some shape or
manner. Fourth, some find an enthusiasm for mathematical thought or mathematical
recreations sufficient.
No single motivation can satisfy everyone. A motivation that is meaningful for
one may seem vacuous to another, and some motivations are not positive.
In modern society or times, science and technology are used to justify
ecological and ethical acts which appall some students. Students see that the
environment is under threat. Many leading elements of our society busily
trying to survive today have the attitude that tomorrow does not count.
Students see the use of technology and science in the creation of war
machines. Students fear that there will be no jobs regardless of what they
study. And students excelling in literature and word-based subjects may find
the symbolic and algebraic exposition of mathematics itself and of
quantitative disciplines alienating – an abstract art. Their teachers in
schools and colleges may be powerless and insecure cogs in bureaucracies that
go forward without allowing initiative. Not all is well. Schools may be like
assembly lines, impersonally processing students or livestock to be moved on
and out. Given the fears that students may acquire, many rational students
will turn away in despair from studies or planning for the future. [1]
[1] As a student and then as an adult I
had a fear and despaired of the ever-present possibility of nuclear war. Much
to my own surprise, thirty years later in 1996, I am still alive but have
refrained from having children. This refrain may continue due to my ecological
pessimism.
In education and society, give students hope or pay the consequences in the
classroom, in the streets and in the morgue – circumstances hopeless or
lacking purpose may lead students to harm (glue sniffing, drugs, crime or
suicide). Compulsory education is absurd and pointless without care for these
other factors.

Words to clearly
introduce algebra and variables
have been missing in course design. For people who cannot do
algebra,
|
the missing words may
explain or ease their difficulties. Volume 2 ,Three
Skills for Algebra, in Chapters
8 to 14 & 18 etc, puts words before symbols to
providing the missing words in a way that enrich the
comprehension of all. Those words form the middle part of a algebra

of high school mathematics and also calculus course
design & delivery.

These may be too dense for students. Offering ideas to change
education makes this site different. Nothing
ventured, nothing gained. Site material is
mathematically correct, and where not, please report
errors. The two level program POMME in the site
entrance implies multiple paths for instruction. Supporting
those paths in turn implies a clear destination for
site development and perhaps a new name.
