Numerous studies have shown that such technologies help students in motivation for teaching content and encourage better cooperation and interaction. Teachers should take advantage of this positive sides and create classes in accordance with the requirements of twenty-first century students. Children are today all previously encountered with information and communication technology, and school should teach them the proper use of this technology from the very beginning. In the present education system it is predicted that the teaching of informatics is held only in subject teaching and as an optional subject. This means that many students, whose parents may not be competent enough, are left on their own until fifth grade in terms of the use of information and communication technology. Primary school teachers should recognize the problem and react in a way that they introduce ICT in the educational process from the first class as part of other subjects that are taught. Most of today's children has a mobile device and they are very easy to apply in the lesson if the teacher is willing to do so. Of course, this does not mean that lessons should be fully turned to technology devices. Lessons should be focused on the students and the development of their skills, while technology should only be used as a tool that helps. It is up to teachers to decide maturely and wisely how to direct the use of technology in a positive direction so that, together with the pupils, they profit in the quality of teaching. In this paper some possibilities of using information and communication technology in education are shown, with a focus on mobile learning.
