The basis of the submitted study are the continuously rising demands to alter the curricula with the aim to develop students' key competences in order to increase their professional versatility. The lack of scientific research and discussions show that little investigation has been done on the issue of development of key competences. Therefore, the primary objective of our study is to present the teaching methodology, the process of creating the educational model and the pilot verification aimed at the development of key competences through interactive whiteboard in the subject of Technology. The partial results of the pilot research conducted on the research sample of 6th and 8th grade students of primary schools on Slovakia show its usefulness especially in the development of teamwork, in terms of interpersonal competences, problem solving in terms of learning competences and reading comprehension in terms of communication competences. The presented educational model reflects the contemporary requirements in terms of using information and communication technologies in the teaching of the subject of Technology, in which the acquisition of key competences becomes considerably important.
