The article presents the technology of application of сompetence-based educational simulators in the informational and educational environment for learning general technical disciplines. It was designed the classification of сompetence-based educational simulators for learning general technical disciplines. There are presented types of educational simulators and outlined professional competencies of general technical disciplines that provide the developed types of simulators. On the basis of passing educational simulators it is formed not only a qualitative indicator of the educational results, but also an indicator of the formation of competencies in the course and curriculum. The method was tested using experimental group and control group (total 1301 students of specialties ‘Agricultural Engineering’, ‘Electrical Power, Electrical Engineering and Electrical Mechanics’, ‘Professional Education’ that studying general technical disciplines) by systematically measuring achievement of professional competencies in the conditions of informational and educational environment by using educational simulators. The results show that higher education applicants in the experimental group achieve better results of acquiring professional competencies.
