Đura Pađan
Đura Pađan

Graduated from The Faculty of Mechanical Engineering of University of Belgrade in 2000, Department of automatic regulating. The thesis was titled "Analog Technique for Regulating the speed of one-way engine". Đura completed his M.A. programme in 2005 and the theme of final thesis was "Pneumatic valves with width-modulated algorithm".From 2001 Đura is a teacher of engineering, technologies and informatics in primary school "Vladislav Ribnikar". He teaches engineering and informatics to the bilingual class. From the beginning of his career, Đura noticed the possibilities for improving education, which he made his goal and worked on it ever since. He incorporated electronics, programming and interface technologies to his curriculum, much before they became a part of official curriculum. As a result, he has students who attend his classes with joy and enjoyment in their work. During his teaching career, he developed models of computer-operated machines, which are basically robots, since they operate autonomously. He thinks that teaching is a two-way street, since everybody is both a teacher and a student. This way of thinking about the calling of the teacher is a key element in success, because teachers and students are equals in their common project called lifelong learning.
