An important role in the formation of qualitative knowledge of physics in the modern education system is played by students` ability to present the processes being studied at a qualitative level. Formation of students' abilities and skills to construct figurative physical models, finding mathematical dependences between physical quantities is one of the urgent problems of physics teaching methods. Our research is devoted to the problem of the formation of high-quality imaginary models of physical processes among physics students on the basis of an educational experiment and digital technologies. To improve the quality of teaching physics, the necessity of forming physical and mathematical models of the studied processes among future specialists is substantiated. On the example of experimental study of processes occurring in DC circuits, which contain inductors and capacitors, a method of forming their imaginary and mathematical models is proposed. A digital measuring system with a personal computer was used in the research. It is proved that conducting a physical experiment with simultaneous display of research results in the form of tables and graphs contributes to the formation of a qualitative level of physical models. To form students' skills of building mathematical models of the studied processes, it is proposed to use software that allows to analyze the results of the experiment. The analysis of graphs of the studied processes allows to select mathematical dependences and to calculate necessary coefficients. The use of digital technologies and related programs provides a quick finding of mathematical models. Changing the parameters of the studied objects while finding the corresponding mathematical dependencies allows students to establish relationships between mathematical symbols and physical quantities. This approach provides students with the ability to find mathematical models of these processes or objects. The results of the implementation of the proposed method showed that the use of digital measuring systems in the educational physical experiment significantly improves the quality of students' learning of new material. Key words: physical experiment, model, digital technologies, extra current, inductance, capacitance.

Special aspects of using modern digital complexes vernier dychimack cycamics

The current level of development of science, technology and modern technologies requires humanity to have a large number of competencies: flexibility of thinking, creativity, rapid adaptation to new conditions and tasks, and others. The National Strategy for the Development of Education in Ukraine for the period 2012–2021 provides for a large number of actions, the implementation of which will increase the efficiency of the educational process based on the implementation of the achievements of psychological and pedagogical science, pedagogical innovations, information and communication technologies. The Ministry of Education and Science of Ukraine, responding to the requirements of modern society, introduces modern information and communication technologies into the educational process. Provides educational institutions with modern computers, interactive whiteboards, other various and various digital devices. This trend is positive and helps to improve the overall educational process, its efficiency, accessibility in institutions of both general secondary education and in higher education institutions. Thus, the task of educational institutions of all levels is to ensure the ability of complexes of students to carry out independent activities with the help of existing modern innovative equipment, modern innovative kits, digital measuring systems. Considering the educational process in higher education institutions, we understand that it should be built in such a way that student learning should meet the goals of advanced learning. Therefore, graduates of pedagogical institutions of higher education must be ready to work with new technologies. The latest digital equipment, complexes, digital laboratories – is a new generation of natural laboratories, designed to conduct frontal and demonstration experiments, laboratory work at the modern scientific and technical level. The use of new digital laboratories allows to supplement knowledge, expand the horizons in other related fields. Therefore, the article considers the feasibility of using modern digital measuring systems in the educational process.

Accuracy enhancement of measurand estimate on the base of additive combined measurements

Purpose The paper aims to develop a method for improving the accuracy of smart sensors (deemed as digital measuring instruments) by organizing combined measurements and processing their results by the parametric adjustment method at heterogeneous dispersion of the random error of the applied regression model. Design/methodology/approach When carrying out combined measurements, the problem of joint processing of measurement results of functionally related quantities must be solved. The function type can be known in advance or obtained experimentally. The number of combined measurements exceeds the number of unknown measured quantities. The redundant measurements can improve the accuracy of estimates of measured values but lead to inconsistency of the measurement results. The problem of inconsistency is solved by the parametric adjustment method, which is rather widely used mainly in the field of geodetic measurements, wherein the parametric equations are linear and the measured quantities are additive. Findings The proposed method allows to reduce the uncertainty of type B of a measurement result, caused by the maximum permissible error of a digital measuring instrument, by 1.2–4 times in comparison with the direct estimation method. Originality/value A compact description of the parametric adjustment method in matrix form is given. Recommendations are given on shaping a sensitivity matrix of functions for the proposed method. The geometric interpretation of the proposed method is considered. The results of the proposed method experimental testing are given when evaluating resistance values.
