The article is devoted to the experimental methodology of forming competencies of seniors by means of sets of modern experimental physics, due to the requirements of the standard basic and secondary education. The purpose of the article is to develop the methodology of forming of the experimental competences of seniors by means of sets of modern experimental physics. To achieve this goal it is necessary to use the following methods: analysis of theoretical sources on the issue of formation of experimental competencies, learning and generalization of the best pedagogical experience, setting and carrying out school physical experiment with modern sets of instruments. The methodological basis of research is leading psycho-pedagogical concept of learning and development of students. The study developed front and demonstration experiments with sets of instruments and propose appropriate methodological support. Listed in article sets of instruments and equipment form the basis of experimental physics learning environment of students in secondary schools. Article attention is paid to the formulation of key indicators formation of experimental competencies of seniors by means of the sets of instruments in experimental physics. Formation of experimental competence is carried out in a learning environment through the prism of activity approach. This includes gaining experience in fulfillment primarily cognitive actions such as educational observation, simulation of physics experiment, actual implementation of the experiment, analysis and interpretation of the results, hypotheses based on the empirical facts and others. Thus, the article outlines the basic parameters of sets of modern experimental physics, clarifies the essence of the concept of “experimental competence” by the possibility of their formation in modern schools and selected key indicators of formation of experimental competencies of seniors by means of the sets of experimental physics. These kits are effective for student learning in higher education. Therefore, we believe it is necessary to conduct a study on the formation of experimental competencies of students by means of modern experimental physics sets.
