Mobile School Service

What is in common for the majority of young people? Mobile phone. In epoch of rapid development of information technologies the time came in which only few people do not have mobiles, especially among young people in high schools. Researches which we made in our school say that this percentage (rate) is really high 99,23% at this moment. The educational institutions should use this opportunity. In aim to improve the success of students the mobile service is developed, which will be described in this work. This is first result which provides a cognitive tool which is supporting the independent learning by applying mobile phones with wireless communication technology to extend learning outside of the classroom in Serbia. The service was developed during times when we didn’t know anything about how much and in which way m-learning was being used in the world.
