IWALT-20001. Introduction

Educational CD-ROMs should be not less interesting and attractive for children then numerous computer games.

1. Introduction

But it is extremely difficult to achieve it, because the development of such games requires huge financial resource.

For development of educational environment it is necessary to solve follow tasks:



IWALT-2000


1. Introduction

1. design of a simple and intuitively appealing interface, in which

educational material is visually combined with navigation tools;

2. determination of information organisation of interactive educational

multimedia and forms of learning material presentation;

3. implementation of software;

2. Metaphors in educational multimedia

It was only natural choice for the book to be one of the main

metaphors in interactive learning environments for a long time.



IWALT-2000



Due to limited hardware possibilities of computers only the visual represen-tation of the text and graphics was possible. Besides the instructional

designer and subject specialist used a book as a convenient and usual way for

representation of knowledge.

Often in multimedia system 3D metaphors are presented to the user

simultaneously with desktop metaphors based on a two-dimensional model.

Virtual reality

It is necessary expansive hardware for implementation of immersive virtual

environment.

“A window to the new world”

Learners look not at a flat surface of the screen of the monitor but look through the glass of the screen like through a

window to a new spatial world of knowledge




IWALT-2000


“A window to the new world”

“The new world” is a three-dimensional world where all information objects

have a shape and behaviour

Three educational modes with the limited structure of navigation tools and information representation are used:

3. Information structure of the CD-ROM

• Learning - a basic mode in which the educational information is organised as a three-level hierarchy;• Tests - a complex of questions for testing the learners’ knowledge;• Experiments - models of chemical experiments

4. Script approach for development of educational CD-ROM

This approach allows to create high-quality multimedia courseware fast and at low expenses, but the choice of presentation tools is

limited by features of the authoring systems.

Software

(II) Programming




The second approach is based on direct programming of multimedia software by using a high-level language.

(III) Script approach



Third approach is based on the use of special script languages for description of navigational information and presentation

structure of educational content.

Scripts Example



IWALT-2000

SCREEN { //1. PIC = u75.png 68,49 PIC = d751.png 179,580 text= t751.txt 0,0 wave= w751.wav FORMULA = 80,180 s752.for 131,137 t 0,58,88 ANIM = o751.flz 200,100 t 0,56,88 ANIM = o751.flz 200,100 t 0,56,88 interactive}



At a script level only the structure and specifications of presentation (attributes of graphics, hotspots, synchronisation,

etc. ) are described for objects stored as files of multimedia database.




IWALT-20004. Script approach for development of educational CD-ROM

The programmer develops an engine of the multimedia

system, a set of presentation modules and software for

script handling. At the same time other staff members

can be engaged in filling of scripts for content. From

those developers only the knowledge of simple

syntactical rules of script writing is required.

5. Conclusion

The main idea of the spatial metaphor for interactive educational multimedia is a screen of the computer being not a representation of a book page, but “a window to the new world”.

2. Information structure of CD ROM

Script approach for development of educational CD ROM allows to make the development of multimedia cost- and time effective.

3. Design methods

Design of educational modes with the limited structure of navigation tools and a standard set of graphic forms for representation of information are used.
