Assignation of model
 Plan-cinematic
model for overhead projecting presents a completely new teaching
expedient.
It developed by synthesis of model and painting in overhead
projecting.
Painting was the only teaching expedient in use during the visual
relative of particular teaching subject. It enabled marking of
ecliptic movement of particular phys, position of particular
elements etc., by using technology of colored paintings.
Static quality of
paintings can not present cinematic relation of some elements –
mechanic so that the teacher had to poses mechanic model of unit.
But the model couldn’t demonstrate vector sizes, dispositions of
particular phys, etc. The most important thing is to mention that
it was impossible to demonstrate some visual processes during the
teaching of some theoretical subject. ( Mechanical engineering-
mechanical engineering elements )
For example:
It was impossible to
demonstrate a period of contact of cog-wheels conjugational. It
was impossible to demonstrate visible active length of contact
place /geometric place of contact of phys/. This process became
visible by using the plan-cinematic model with adequate painted
foil, and using of this model enables wide level of exactness.
Very important thing is that the assigned model enables repetition
of visual sensations what makes a maximum effect in recollecting
process. Plan-cinematic model with some paintings on foil enables
teaching of more than one methodical units by using one single
model. This makes model very useful.
For example:
 “Model
of piston mechanism“ enables teaching of turning the rectilinear
piston’s movement into a circular movement of angle crossbar. Work
of four-tact motor could also be explained by this model with
painted foil that explains determined tact of motor’s work:
absorption, compressive expansion and exhaust stroke.
Plan cinematic model
for overhead projecting has a miniature dimensions 150 X 200 mm.,
preferential to hold and carry and long lasting in use with a bit
of carefulness.
