LUGRAM in primary school.

The 3th grade pupils (two classes) of Primary school "20th October" in Sivac, Serbia ( 2006/07. school year), were the experimental group in the research project "Educational Software type educational game in teaching mathematics (eg. geometry) I-IV grade of primary school".

Lugram is a puzzle game based on composing the given geometric figures. Lugram has been designed as a motivational factor which makes the teaching process of geometry more efficient and teachers and pupils more active.

After the game organized by using print media, software version of Lugram (multimedial, interactive, game levels adjusted for pupils) successfully performed the role of a motivational factor in experimental group.

The method of application Lugram emphasizes the importance use of new media (such as the educational software) in the contemporary teaching of geometry. Cardboard media informed the pupils about the game. Software version had the task to raise the level of pupils interest for the game. We used two teaching media on the same task.

Is useful LUGRAM "consequences" can be demonstrated later in teaching geometry? Do Lugram can contribute to forming a solid basis in the initial learning of geometry, for all further steps?

For example: Pythagorean theorem


LUGRAM - further research - version for blind children

Simple concept Lugram games and features of the developed module, enabled adaptation the version Lugram for partially sighted children. Using the keyboard instead of mouse, created sound signals and effects, as well as support with voice messages for instructions and play are important to adaptation needs of visually impaired users. Special challenge was the development Lugram for blind children.


Lugram modular concept, simplicity of the basic version Lugram_III, successful application in teaching, a fundamental matrix of (3x3) figure-task, caused that one of the directions of further development of Lugram is adjustment to the play Lugram using only standard PC keyboard (primarily separate numeric PC keyboard).

Results after the first tests:

Lugram - version for blind - the first tests (monitor obscured for the sighted children)


Lugram version for blind children uses a voice messages which have formed by using TTS technology (AlfaNum Sne┼żana, for the Serbian language (AlfaNum, Novi Sad and Faculty of Technical Sciences, University of Novi Sad, Serbia).

The first step towards an additional software support for the Lugram for blind will be the inclusion of automatic-speech-recognition (ASR) technology for the Serbian language ( Prototype has been supported by ASR functionality, allowing users to play Lugram using voice commands. The first tests are described in article, Educational Applications for Blind and Partially Sighted Pupils Based on Speech Technologies for Serbian (The Scientific World Journal). The achieved connection of game module with the AlfaNum ASR has opened a new chapter in adapting of Lugram to visually impaired and disabled people in general.
