Nowadays, with the rapid development of
Internet
technologies bring new interactive services for Internet and
Intranet-networks,
as for example, distance learning. Distance Learning System is a very
popular forms
of education in the world in those countries a high level of
development of
communications-based computing. Preparation of modern
specialist s demands
the organization of the educational process with the use of new
information
technologies and using systems based on knowledge - Expert Systems (ES).
The use of ES for the assessment of students'
knowledge in test systems constitutes an important unit of computer programs - expert
training systems (ETS).
Expert and training systems - that computer
programs
have illustrating the principal components of the ES, but have expanded
further
explanation component. These systems are based on expert
knowledge as
software and knowledge of experts by the method of
teaching. In addition,
they have a component of the adaptation of presentation of educational
material
to the student depending on his fitness. And at least there
are several
strategies for learning, the level of detail of which depends on the
activity
of the trainee in the catalog are with dial system [3].
In view of the widespread use of computers, the
role
of computer-based training, a technique which increases the student's
intellectual ability and autonomy of decision making. And these
qualities are
most in demand in a competitive economy and contribute to the
educational and
professional growth. There is the problem of creating effective
learning
systems, as well as creating new forms and ways of presenting
educational
material, searching for new teaching methods and means of teaching [1].
One of the ways to increase the effectiveness of teaching, learning
information
and reduce the cost of the process of learning is the development and
use of
automated expert training systems. At this time, there are many terms
for
automated peer-learning system, which, in fact, are similar [2].
The most popular
of these are the systems of distance learning, computer training system
and
others. To explain the meaning of the above terms may result in the
following
definition.
Expert Training
System (ETS) - a set of software and hardware, and teaching tools that
are
based on expert knowledge of the domain (qualified teachers, teacher
trainers,
psychologists), implement and monitor the learning
process. The purpose of
such a system is that it is, on the one hand helps the teacher to teach
and
control plated student, and on the other side of the student self-study
[4].
2. Goaks and tasks of the research, expected
results
The aim of this study is to develop a computer
expert
training system that will help increase the amount of learned knowledge
and
perception of the effectiveness of information, and reduce the time to
study
the subject, including the time spent by the teacher to present
information and
to impart practical skills of students.
The main
objectives of the study:
1) The development
of an ontological model ETS;
2) Development of
the structure of the ETS;
3) Rationale and
implementation of computer-assisted selection;
4) The introduction of the active components in
the
ETS (games, interactive systems, direct access to communication, such
as
through Skype with the head);
Object of study:
expert training system.
The subject of the
study: the model of the structure and function of the ETS.
Scientific novelty
is a new approach to the design of ETS based on the modeling of the
student and
the application of artificial intelligence methods.
As part of the
master's work is planned to obtain relevant scientific
results in the following areas:
- Modeling of learning processes.
- Designing the structure for ETS Internet and
Intranet.
The expected
outcomes of the work: Second prototype of expert systems s her
schooling,
which will improve the quality of teaching and learning to reduce the
time I
am.
Because the
research questions of expert training systems and improve the
efficiency of
learning in this system are important parts of solving complex problems
using
expert systems. ETS has been widely studied both foreign and
domestic
experts.
3.1. Overview of international sources
First Plato
Learning System based on a powerful computer company «Control
Data Corporation
»was developed in the
3.2. The Browse national sources
By modern teaching systems include systems TrainingWare, eLearning Server 3000
v2.0, eLearningOffice 3000, IBM Workplace Collaborative Learning and HyperMethod 3.5 HyperMethod
company, which is Russia's largest developer of turnkey solutions and
software
in the field of multimedia, peer-learning and e-commerce [5].
Expert Training
System (ETS) - a computer program based on the knowledge of experts of
the
domain (qualified teachers, teacher trainers, psychologists), implement
and
monitor the learning process. The purpose of such a system is
that, on the
one hand and helps control the instructor to teach the student and the
other - Student self-study [5].
The main
components of ETS are:
- Knowledge base;
- The inference
engine;
- Knowledge
extraction module;
- Training
module;
- Explanation of
the system;
- Module testing.
During training,
expert knowledge can be transferred to the student in the form of a
piece of
information (text first, graphic, multimedia), as well as knowledge
based on
experience that can not be passed directly to the student, and
purchased by him
in the course of e independent activity [6].
Knowledge transfer
experts widely used technology developed hypertext - from traditional
aid
programs to create (help) to contemporary creation tools and support
Web-sites
(like Dreamweaver MX).
The training
component is a set of software modules that implement different
mechanisms to
achieve the withdrawal of pedagogical goals in training. ETS, unlike
other
learning software have interactive: have a dialogue with the learner,
which is
very attractive to the latter [7].
Building a
dialogue based on the basic psychological principles of training:
- User-friendly
interface;
- Leave the
dialog at any time;
- Timely help and
motivated.
Each question
asked the student, need to think carefully when necessary to provide a
more
detailed question to better understand it.
The study shows
that many of the components of creating ETS depend on the result of
training,
so to create a knowledge base ES needs specialist who has excellent
knowledge
of the subject area, as well as methods of teaching has assured [9].
ETS,
unlike other computer
technology training are able to implement the learning process on the
individual student model. Training
with ES focused on the extraction of
knowledge by learners. And
these are the specialists are in demand in today's
job market. ETS also has its advantages and disadvantages.
Major drawbacks associated with learning expert systems can be divided into psychological, related to the lack of "live" communication with the teacher, demanding and self-organization specifications, which are caused by the imperfection of content, technology, and telecommunications infrastructure.
