A GRADE POINT AVERAGE = 3.14797364528243500325637
IS RIDICULOUS. WHY?
Many people are apparently unaware of just
how ridiculous the practice of grade point averaging is. This includes (unfortunately) many
educators and educational bureaucrats, who should know better. These
people assume that a simple number, for example 2.7, can actually represent a
grade point average that absolutely reflects a student's skill and effort and
learning. It does not matter whether the student went to Harvard University or to a community
college. It doesn't matter whether the student majored in biology with a
minor in genetic splicing or in basket weaving. It doesn't even matter if
one student was in college and the other student was in middle school. A
grade point average is widely thought to be the kind of measurement that is as
precisely fixed as the places of the stars in the firmament.
This is nonsense. It is important
that this is recognized as such because it leads to a major injustice when
students are denied state funded scholarships because of phony grade point
average requirements. In South Carolina there are thousands (and
probably tens of thousands) of students who have lost Life Scholarships on the
basis of grade point average requirements that are arbitrary, irrational, and
inconsistent.
In South
Carolina students are required to maintain a 3.00
grade point average to maintain a Life Scholarship, for example. In fact
the state violates the constitutional rights of college students to due process
and equal protection when it takes a Life Scholarship away from a student with
a 2.8 or a 2.9 grade point average. Forget about the 3.00 grade point
average requirement. If a 3.0 grade point average mean
"good" work, then what does a 2.9 grade point average mean?
Less than good work?? And then what does a 2.8 grade point average
mean? Less than less good work?? And then what does a 2.7 grade
point average mean? Less than less than less good work, but better
than average work?? Trying to pin down what these numbers mean quickly
becomes absurd. In other words the state of South Carolina (along with other states) is
taking scholarships away from students on the basis of meaningless,
unreasonable, absurd criteria.
In this country grade point averaging
assumes that millions of different educators --- who are teaching hundreds of
different subjects at thousands of different schools to different age groups
--- can be mathematically precise in assigning “good” grades for good “work”
where there is no uniform understanding for what is “good” and what is
“work”. This is like assuming that millions of people can assign and
average grades to rationally compare things as varied as books, kitchen sinks,
cars, vacation resorts, cigars, hotels, schools, investments, magazines,
physical beauty, musical compositions, sports teams, restaurant meals,
etc. Averaging grades like this completely ignores the
content-value-context-price-skill level of what is being evaluated.
This is not even wrong. It is an irrational
misuse of numbers. It is like saying that a 3.03 grade point average
apple from an American orchard is better than a 2.98 grade point average
automobile made in Japan
by exactly 0.05 degrees of “goodness”. This is nonsense. Millions of
educators can repeatedly and uniformly agree that an object weighs 2.3 or 3.82
or 1.596 etc. pounds with a suitable scale. However, there is no
objective unit (like the inch or the pound) or instrument (like a ruler or a
scale) for measuring academic “goodness” or for measuring academic
“work”.
Irrational mathematical comparisons of grade
point averages represent the claim that already vague and subjective measures
of “goodness” (like a college grade of B without reference to subject, school,
educational level, etc.) can be subdivided and refined yet further into ten
(3.0), or a hundred (3.00), or even a thousand (3.000) sub degrees of
“goodness”. Grading crimes and criminal punishments according to this
kind of “mathematical logic" would not be tolerated for a moment because
it would violate the due process and equal protection clauses in the
Constitution. Imagine trying to imprison someone for what is described
as precisely 2.78 degree “bad” behavior, or “bad” behavior in the 2.78th
degree. Imagine trying to explain how being "bad" in the 2.78th
degree differs from being "bad" in the 2.79th or in the 2.77th
degree.
In fact numbers like this are meaningless,
and attempting to use numbers in this way is disingenuous. In taking away state funded
scholarships from college students that are worth $20,000 or more, states like South Carolina use
subjective, unscientific, misleading grade point average comparisons in ways
that violate the constitutional rights of students to due process and equal
protection. These states are guilty of using deceptive, flimflam
arithmetic in deciding who gets to keep state funded scholarships.
This needs to stop. That is, this needs to stop if this country
is going to have an excellent educational system. It
is impossible to achieve educational excellence when the markers for academic
achievement and for spending huge sums of money on education are meaningless
and intellectually dishonest.
POSTSCRIPT
None
of these comments are meant to imply that all grading systems for measuring
academic achievement should be rejected.
How grading systems should be organized is a subject for another time
and place.
What
this article is saying is that current systems of grading students are accepted
by people who do not understand that arbitrarily assigning a precise number to
a subjective quality (for example, a student’s understanding of English literature)
and then comparing this to another arbitrarily precise number (for example,
another student’s understanding of art history) is not the same as precisely
and objectively making comparisons which involve physical measurements of some
kind.
Furthermore,
it is a fact that in today’s educational systems programs for grading and
testing students are corrupted by political considerations and money. In today’s educational systems anyone who
trusts in the government’s promises to leave “no child behind” in another ten
years is simply gullible. An educational
system that is governed by money and political correctness is incapable of
evaluating itself objectively or of making reliable promises for future
educational programs. In this writer’s
opinion any of the statistics or information about testing students that comes
from a government educational bureaucracy is worthless.
Fortunately,
free, privately funded, easily accessed, convenient, high quality Internet high
school and college programs will enable millions of students and their families
to ignore expensive government (and quasi government, or so-called “private”)
programs of education. With free,
high quality online educational systems students and parents (and anyone else)
will be able to choose free educational programming that conveniently meets
their needs whenever they are ready to study and learn. This will be the ultimate in “school choice”.
