The main task of the school today is not just to equip students with a certain set of knowledge, skills, and abilities, but also to form their ability to learn, work in a group. Based on the above, it is advisable to use interactive teaching methods in math lessons. One of the most popular strategies for interactive learning is collaborative learning. The article discusses interactive teaching techniques and their features in teaching geometry in high school. Given examples of the application of the «error method» in the study of the topic «The cross-section of the polyhedrons» are given. It is shown that, when discussing erroneous decisions in collaborative learning, students acquire the skills to solve such problems. The article fills in one of the gaps that exist in the methodological literature on the description of interactive methods of teaching geometry in high school.

One of the most important tasks of training today is the development of the student's creative potential. The teacher needs to create conditions in which the student would seek to get new results of their work and then apply them in practice. The collaborative learning method refers to interactive learning methods and promotes and contributes to the formation of the creative personality of a student capable of self-development and self-education and transition from formal assignments to the active role of the student, able to defend own opinion when performing tasks. Interactive methods of teaching stereometry are not well represented in the methodological literature. The article discusses the theoretical foundations of interactive teaching methods and provides fragments of lessons on the topic «Volume of polyhedral» using the method of teaching in collaborative learning.

This article explores the implementation of interactive methods in teaching psychology of professional education. The object of this research is the process of teaching the discipline “Psychology of Professional Education”, while the subject is the interactive methods of teaching this discipline. The article employs the method of theoretical analysis of scientific and methodological literature, methods of generalization, synthesis, comparison, and classification. The author discusses the essence of interactive teaching methods and their role within system of modern teaching techniques. Special attention It is emphasized that each class can be conducted using interactive teaching methods, selected by the pedagogue based on the desire to improve the effectiveness of educational process and develop professional competencies of students. The scientific novelty consists in determination of specificity of using interactive teaching methods within the framework of the discipline under review. It is established that heuristic conversation, psychological diagnostics, method of projects, role games, and problem-based learning are considered as most effective interactive teaching techniques. The acquired results can be applied in organizing educational process with regards to psychology of professional education and other disciplines of psychological and pedagogical orientation. The conclusion is made that in teaching psychological-pedagogical disciplines and future pedagogues, the students learn how to implement these methods in their future pedagogical activity.

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.

The energy distribution in an electron; beam from an electron gun provided with a biased Wehnelt cylinder was measured by a retarding potential analyser. All the measurements were carried out with a beam of small angular divergence (<3xl0-4 rad) to eliminate the apparent increase of energy width as pointed out by Ichinokawa.The cross section of the beam from a gun with a tungsten hairpin cathode varies as shown in Fig.1a with the bias voltage Vg. The central part of the beam was analysed. An example of the integral curve as well as the energy spectrum is shown in Fig.2. The integral width of the spectrum ΔEi varies with Vg as shown in Fig.1b The width ΔEi is smaller than the Maxwellian width near the cut-off. As |Vg| is decreased, ΔEi increases beyond the Maxwellian width, reaches a maximum and then decreases. Note that the cross section of the beam enlarges with decreasing |Vg|.

The work of multilayer glass structures for central and eccentric compression and bending are considered. The substantiation of the chosen research topic is made. The description and features of laminated glass for the structures investigated, their characteristics are presented. The analysis of the results obtained when testing for compression, compression with bending, simple bending of models of columns, beams, samples of laminated glass was made. Overview of the types and nature of destruction of the models are presented, diagrams of material operation are constructed, average values of the resistance of the cross-sections of samples are obtained, the table of destructive loads is generated. The need for development of a set of rules and guidelines for the design of glass structures, including laminated glass, for bearing elements, as well as standards for testing, rules for assessing the strength, stiffness, crack resistance and methods for determining the strength of control samples is emphasized. It is established that the strength properties of glass depend on the type of applied load and vary widely, and significantly lower than the corresponding normative values of the strength of heat-strengthened glass. The effect of the connecting polymeric material and manufacturing technology of laminated glass on the strength of the structure is also shown. The experimental values of the elastic modulus are different in different directions of the cross section and in the direction perpendicular to the glass layers are two times less than along the glass layers.
