A virtual laboratory is a software and hardware complex that allows experiments to be carried out
without direct contact with a real installation or in the complete absence of it. In the first case, we are
dealing with a so-called laboratory installation with remote access, which includes a real laboratory, software
and hardware for managing the installation and digitizing the data obtained, as well as communication tools.
In the second case, all processes are simulated using a computer.
Electronic educational resources based on modern computer three-dimensional simulation of
physical processes and phenomena are implemented in the form of multimedia educational and scientific
laboratories or virtual simulators. The novelty of the technology of virtual simulators is substantiated by the
use of modern means of computer modeling and the active introduction of information technologies in the
field of education.
Let's formulate the main reasons for using the technology of virtual simulators:
-
existing laboratory stands and workshops are insufficiently equipped with modern instruments,
devices and apparatus;
-
most laboratory stands and training workshops were put into operation after decommissioning, do
not meet modern requirements and are morally outdated, which can distort the results of experiments and
serve as a potential source of danger for students;
-
laboratory works and stands require annual improvement, which leads to additional financial costs;
-
in such areas as, for example, building materials science or physical chemistry, in addition to
equipment, consumables are also required - raw materials, the reagents of which are quite high. Of course,
computer hardware and software are also not cheap, but the versatility of computer technology and its
widespread use compensate for this disadvantage;
-
modern computer technologies make it possible to observe processes that are difficult to
distinguish in real conditions without the use of additional equipment, for example, due to the small size of
the observed particles;
-
virtual simulators make it possible to simulate processes, the flow of which is fundamentally
impossible in laboratory conditions;
-
virtual simulators provide an opportunity to penetrate into the subtleties of processes and observe
what is happening on a different time scale, which is relevant for processes that take place in a fraction of a
second or, on the contrary, last for several years;
-
safety - an important advantage of using virtual laboratories in cases where work is in progress, for
example, with high voltages or chemicals;
-
due to the inertia of work or processes on some laboratory facilities for the allotted time for them, it
is difficult to re-analyze or check;
-
the acquisition by trainees of sufficient skills and work experience in a particular field requires the
need to repeat classes, which is not always done in order to avoid frequent breakdowns of installations and
additional costs for consumables;
-
virtual simulators are a highly effective teaching method, which is due to the low level of
abstraction of the educational material contained in them, in other words, the virtual learning environment in
multimedia educational and scientific laboratories simulates real conditions as much as possible.
For the study, virtual laboratory stands are being developed, in which the dynamics of the ongoing
processes in automation and telemechanic systems is realized through computer animation. Initially, all the
processes of forming the concepts of defining features, their analysis and synthesis, the development of
animation displayed on a computer display in certain sequences are developed by a specialist.
