In
the
3 rooms next to the windows of the
walk, it will be taught private
classes and English courses,
separating the children and their
companions of the older students, in
appropriately reduced groups to get
the personal attention required.
In this center we
consider that if the books and
audio-visual material are correctly
developed, the classes with a
professor dedicated to writing notes
on a blackboard are a waste of time.
In addition, it usually happens that,
the teachers of public centers, after
obtaining their degree it goes
directly to the classrooms, without
requiring experience in the real
world, with which they can hardly
differentiate the useful from the
useless. In addition, the exercises
that appear in the exams are copied
from the books of solved problems that
the publishing houses facilitate to
the educational centers, discarding
solutions with hypotheses of work
different from those supposed in these
books.
To justify
the current system of education as
nurseries, it taught at a
level and it examine at a slightly
higher level. Examples:
Children are
forced to memorize the multiplication
table, without explaining that it can
be obtained from a Cartesian table by
adding values, and that thanks to the
commutative property, it is only
necessary to memorize half.
Spelling is taught dictating stale
literary texts, rather than searching
for lists and mnemonic phrases that
group words that contain phonetically
conflicting characters such as h, v,
g, and accents in plain words.
They teach
the rules of algebra and the way to
check the result of a system of
equations, but without explaining that
there are systems of indeterminate
equations that have no solution
because some of the equations is
repeated or is in contradiction with
the rest .
It is taught to
solve fractions with integer values,
without explaining the general method
suitable for real values ??in general.
Or, it is given a formula to add
fractions, instead of explaining that
multiplying each fraction by the
fraction required to obtain a common
denominator, and taking common factor,
it is not necessary to memorize
anything. Thus, for example, it is
given the formula to add two
resistors in parallel, without
explaining the general casein which we
have more than two resistors.
It is taught the
rule of three, instead of using
conversion factor,that is, simply
multiplying and dividing the 3 data so
that their units are simplified,
without memorizing
anything. It is
taught to raise problems of
trigonometry, without explaining that,
in many cases you can only clear
variables in one direction,having to
solve by trial and error the other
cases. This problem is evident in
Electronics.
In resolution of
limits, it is necessary to carry out
difficult steps that are difficult to
guess at the time of examination,
without explaining that, even in
trigonometric expressions, the limit
can be found by substituting the
variables of the function for the
value under study. For example,
substituting pi / 2 for 3.1416 / 2.
In integral
calculus, there are applied
elaborate substitutions of variables
difficult to guess in time of
examination, without explaining that,
in fact, all function is derivable,
but it can not always integrate a
function to obtain its derivative.
In Temodynamics,
the problems usually lack some data,
which depends on a working hypothesis,
which requires to assume that some
parameter remains constant. That is,
it is about guessing the working
hypothesis used in the book of solved
problems, especially when abstract
parameters such as Entropy are
involved that depend on experimental
tables, not available for all
compounds and possible mixtures.
In short, it is advisable to go one step
ahead of the teacher to avoid the traps that may
contain the exams.
