Modifications of the continuation method for the solution of systems of nonlinear equations
No full textModifications are proposed to the Davidenko-Broyden algorithm for the solution of a system of nonlinear equations. The aim of the modifications is to reduce the overall number of function evaluations by limiting the number of function evaluations for any one subproblem. To do this alterations are made to the strategy used in determining the subproblems to be solved. The modifications are compared with other methods for a wide range of test problems, and are shown to significantly reduce the number of function evaluations for the difficult problems. For the easier problems the modified method is equivalent to the Davidenko-Broyden algorithm

The research methodology is based on the Law of Ukraine «On Education», the Concept of Science and Mathematics Education (STEM-education), the requirements of educational programs in science subjects. The author relies on his own long experience of working in the teacher training system, in particular, in the Chernihiv Regional Institute of Postgraduate Pedagogical Education named after K. D. Ushinsky, where he developed and implemented the corresponding author's courses and seminars in the educational process, and created the didactic content, in particular, photographs demonstrated their effectiveness in practice, that is, during training sessions. Photographic materials created by the author are used for setting problems in physics and became the subject of his scientific research, which is reflected in the relevant scientific and scientific-methodological works.
The content of the article is aimed at satisfying the requests of scientists, teachers of institutions of higher education, in particular institutions of postgraduate pedagogical education, teachers who are not indifferent to the problems of educational development.
The scientific novelty of the research lies in the fact that the author proves the necessity and possibility of creating the named didactic materials by direct participants in the educational process, which contributes not only to increasing the effectiveness of education, but also to the development of the creative abilities of the teacher and his students. At the same time, it is shown how to prepare a teacher for such an activity.
The results of the research were reported at international scientific conferences (Republic of Moldova – 2011, 20213, 2019, 2021, 2022; USA – 2022) and others. and implemented in pedagogical practice at Tiraspil State University, Chisinau State University, T. H. Shevchenko National University «Chernihiv Colehium», Chernihiv Regional Institute of Postgraduate Pedagogical Education named after K. D. Ushinskyi.
Conclusions. The educational process in science subjects always requires new technical means and didactic materials. Interesting didactic materials in this regard were and remain photographs of natural phenomena.
Photographic images of individual moments of images of natural phenomena contribute to a deeper insight into their essence, and, therefore, to their better understanding.
The development of modern photo and video technology makes it much easier, compared to the past, to obtain moments of the course of fast-moving phenomena. It is important that the mentioned technical means have become available to wide sections of the population, in particular to teachers and their students.
A significant number of educational photographs can be obtained by the teacher who, more than anyone else, feels the need for them to achieve a specific goal of the corresponding educational session.
Involvement of students in photographing moments of natural phenomena not only contributes to their better assimilation of educational material, but also to the development of their creative abilities.
In order to carry out purposeful training of teachers of physics and other science subjects to create new didactic materials in the form of photographs, appropriate work should be carried out on courses to improve their qualifications

PROBLEMS AND SPECIFIC RESULTS OF TRAINING PHYSICIANS TEACHERS TO WORK WITH CREATIVELY GIFTED STUDENTS
No full textThe purpose of the work is to familiarize interested scientists with the peculiarities of the author's implementation of the study, which concerns the training of physics teachers to work with creatively gifted students and obtained with separate results.
The methodology of the research was maximally adapted to work with teachers in the system of postgraduate pedagogical education, which includes courses for improving their qualifications, as well as systematic work with them in the course of the course (seminars, webinars, work in creative groups, individual and group counseling, work in groups of social networks, etc.). In addition to analyzing available scientific and scientific-methodical sources, the author monitored the educational process in physics at school, in particular the process of preparing students for their creative projects. by the process of setting up and solving creative, in particular, inventive tasks. Observation of the author was accompanied by video recording, which allowed to carry out a more in-depth analysis of individual actions of both the teacher and his students. The resulting video materials were then used to correct the teacher's activities, as well as multimedia teaching tools for work on all subsequent courses. A separate point of the study was a pedagogical experiment.
The scientific novelty of the research is that for the first time the author has scientifically substantiated the possibility of preparing a physics teacher to work with creatively gifted students in the system of postgraduate pedagogical education. The results of the study were published by the author in the specialized editions of Ukraine, the Republic of Belarus, the Republic of Moldova and the Russian Federation.
The results of implementation in pedagogical practice, in particular, in the system of postgraduate pedagogical education of teachers of physics in Chernihiv and other areas, are obtained.
Conclusions. Teachers began to differentiate the creative, intellectual and research activities of man, as well as mastered the methodology of diagnostics of abilities for scientific and technical creativity.
Teachers have learned to make creative tasks in the educational process in physics. They have become more meaningful to provide their students with assistance in carrying out their training projects.
In our further research, we plan to offer new organizational forms and methods for teaching teachers and students, in particular using Internet resources
