Kabardino-Balkarian State University,
Designed by Sultanbek Tezadov
The on-line tutorial «INFORMATICS», http://www.kbsu.ru/~book,represents a base course of Computer Science
Fig.1. The front page of the on-line tutorial
"Theory" and "Practice".
Fig.2. The «Theory» part review
The on-line tutorial is intended for high school students, students of universities and teachers of Computer Science. The tutorial will also be a good help for a person that wishes to comprehend a base of Computer Science independently.
Fig. 3. A typical design of sections of the "Theory" part
The information part represents the contents of my textbooks, made as a Hypertext. The operating systems Windows 95/98/NT 4.0 and browsers Internet Explorer 5.x, Netscape Navigator 4.xx or Opera 4.0

from a browser in one of the two environments of programming:
Borland Turbo Pascal and Microsoft Quick Basic.
The practical part includes tasks and exercises of the theoretical
unit, and also more than two hundred problems for solving.

that cover processing of the numerical, textual and graphic information.
In the beginning of each unit there are demonstration examples
planed to be the samples for imitation of problem solving tasks.
Fig. 6. The contents of one of the "Practice" part chapters
are realized in four environments: on a pseudocode, in flow-charts and in Turbo Pascal and Quick Basic.

pendent solving which are structured by the degree of difficulty
Fig. 8. The view of "Problems for solving" section
The browser of the user is integrated into Turbo Pascal and Quick Basic. To start a chosen environment of programming it is enough to click on the appropriate button: "Turbo Pascal" or "Quick Basic".
Fig. 9. Organizing of Pascal and Basic IDE startup
is loaded on environment of programming. The user will
need only to start the program. The same mechanism is used at
a stage of independent solution of tasks.

Each task for problem solving is supplied with "pattern" of the solution. The pattern represents "skeleton" of the future program with prepared test data. The user has an opportunity to expand a pattern to the ready program and then to check up its serviceability.

One more advantage of integration of a browser with programming environments is an opportunity of use the built-in Help system.

of programming environments that allow to better catch logic
of the programs, viewing of intermediate values variable in
a window Watches, use of conditional breakpoints etc.

Fig. 14. Knowledge testing window view
Several testing modes are used. In the most rigid mode students have to answer questions within a given time period.
In a softer mode they are not limited in time.
Fig. 15. Text questions window view
In learning mode students can receive a short hint or a full answer to the question.
There are also statistics pages, which provide information on student performance by groups, courses and faculties.
