In 21st century, schools and teachers face numerous challenges, one of which being the important and everpresent role of information-communication technologies in education, as well as in everyday life. Possibilities of such technology are more than ever used to shape teaching experience into a more interesting and interactive form – with a clear goal in mind, students achieving better results, having higher motivation and interest for education material. Numerous tools exist, programs and applications alike, which gives teachers and school many different option of integrating it into education, however – it is clear the industry gravitates towards smart devices and mobile applications, one of main reasons being everyday usage of smart devices throughout all age groups, especially students across all levels of formal education. Even with smart devices, especially smartphones, being available to the majority of global population and their capabilities being greater with each passing day, smart devices still fall under the stigma of being too distracting to be helpful in formal education. The goal of this thesis is to explore ways of smart devices to be integrated in computer classes, focusing on high schools. This thesis also strives to analyse ways smart devices already are integrated and to find out whether the stigma is in fact true – are they too distracting? The conclusions of an accompaying research are built upon answers and thoughts of teachers of computer sciences in educational institutions, as well as students majoring in computer science, teaching-oriented programme. Research is analysing their opinions on integration of smart devices in classes, their experience of students using smart devices as means of escape, rather than useful educational purposes, and trying to understand how much are current and future teachers truly acquainted with the possibilites of smart devices in the context of education.
