Transcript distance learning system «Web

INTRODUCTION
• The most actual questions is using of modern
information technologies in areas of mental
activity, what are most difficult to understanding,
when the difficulty of training is depended on much
work.
• On the basis of Laboratory of the integrated
environments for learning of Scientific and
research institute of informational technology of
Kherson State University distance learning
system «Web-Almir» with supporting practical
training of students on course of linear algebra was
developed.

INTRODUCTION
a personified
system: every
user has his own
• «Web-Almir»
Environmentisinterface
is designed
in Ukrainian,
work
area and
distant
access
to his work desk.
English,
Polish
and
Russian.

INTRODUCTION
• System «Web-Almir» allows leading training
and knowledge test to corporate networks
and Internet, in addition, it can be used as a
tool for traditional forms of studying.
• System «Web-Almir» gives possibility the
user to carry on active practical activity, which
is cognitive, researchable, and use modern
information technologies as the instrument of
creative cognition process.

SYSTEM CONCEPT
• System architecture
–
–
–
–
–
open architecture
independence of a subject
remote access
personification
centralized repository
• Tasks’ solving environment
– operation of the user with real objects
– complete freedom of action within the limits of a subject
domain
– "friendly" interface of the program
– keeping the history of user action
– assistance in "difficult" situations

TEXT BOOK
• Text Book is the significant module of system.
• Theoretical material is presented in the Text Book
according to learning plans of Ministry of Education
and Science of Ukraine
8
TASK BOOK
• Task Book is a system module, which includes all
task, supported by a decision tool.
• Task Book can be dynamically updated.
9
COPY BOOK
• Copy-book stores tasks solved by user.
10
TASKS’ SOLVING ENVIRONMENT
• At each step of task’s solving the user does
some converting of mathematical object:
numbers, matrixes, systems of linear
equations, vector.
• User can focus on the algorithm for solving
particular task, all routine actions
environment are performed automatically.

EXPERT
• An important feature is the way out of
‘problem’ when the user does not know what
step should be the next.
15
STATISTICS
• Statistic allows gathering data and
performing analysis to constantly monitor
user’s progress.
16
CONCLUSION
• Information and communication technologies, being a
very promising and the best solution, play special role in the
learning process.
• Computer training programs allow you to individualize the
learning process, enhance motivation to learning.
• Using «Tasks’ solving environment» is a very effective
for teaching linear algebra course.
• It combines traditional techniques, allows the user to focus
on the algorithm for solving the problem, and all routine
actions environment are performed automatically.
• New forms and methods of information technology use in
linear algebra studying allow significantly reinvigorating this
process, what has a positive effect on future professionals
training in general.
