PRACTICE OF IMPROVEMENT OF PHYSICAL AND MATHEMATICAL EDUCATION OF TEACHERS AND PUPILS (ON THE EXAMPLE OF THE ORENBURG REGION) [№ 1 ' 2018]
Improvement of physical and mathematical education of teachers and pupils of mass school becomes a key factor in the conditions of creation of national and regional system of independent monitoring and assessment of quality of such education as way of external assessment of results for the benefit of the personality, society, labor market and the state. Changes in economic, political and social life have strongly influenced formation of new type of the identity of the person, on his emotional and intellectual world that demands, obviously, search of effective forms of learning and the doctrine, reconsideration of values, moral standards and all outlook of the person. At the initiative of the Ministry of Education of the Orenburg region there was an effective system of improvement of quality of physical education on the basis of cooperation of physical faculty of the Orenburg state university and teachers and pupils of Orenburg and the Orenburg region. The called system provides, first of all, improvement of subject competence of the teacher of various programs of professional development, profound training of school students at University physical and mathematical school, various forms of educational and research, design and Olympiad activity in branches of department of the general physics and educational laboratories of physical faculty. The educational programs of higher education institution which are implemented on University Saturdays and Public lectures on physics are traditional. Result of long-term joint interdependent educational activity of the university and teacher's, and school community are results of graduates of the main and high (full) school on the Basic and the Unified state examination, at the Olympic Games and conferences of the Russian and regional level.

TO THE QUESTION ABOUT ORGANIZATION OF THE INTRODUCTION COURSE "MATHEMATICAL PROCESSING OF EXPERIMENTAL DATA" [№ 7 ' 2015]
The various approaches to introduction of the course "Mathematical Processing of Experimental Data" are considered in the article. It is noted that application of traditional statistical approach has a lot of essential shortcomings. The possibility of experimental finding of the necessary number of direct measurements of physical quantity sufficient for receiving the limit absolute error is proved. It is offered to imitate results of direct measurements by means of a computer mathematical MathCAD package, generating the random variable having normal distribution. As a result of numerous measurements there is not displaced estimation of an average square deviation providing a limit absolute error of result. Expediency of finding of absolute errors of results of indirect measurements by means of a method of borders for which it isn't required the knowledge which is far going beyond the school program is proved. Features of application of this approach to processing of results of indirect measurements are illustrated on two examples . Expediency of use of the interactive methodical instructions integrated with a computer mathematical MathCAD package for increase of efficiency of assimilation of this course by students of the natural-science and engineering directions is noted. In this case the operating control of correctness of mathematical processing of experimental data in audience leads to sharp increase in motivation of students to studying of the considered material.

PHYSICAL TECHNIQUES OF RESEARCH OF THE POLYMINERAL CLAY CONTAINING THREE-LAYER ALUMINOSILICATES [№ 1 ' 2015]
The results of spectral and analytical research of structural characteristics of clay containing montmorillonite — chlorite from the Orenburg region are presented. It is established that data of chemical and X-ray analyses of structure are well agreed with data of IR-spectroscopy supplemented each other. Methods complex applying has helped to establish Fe quantitative content in clay and its entry into layered silicates lattices as replacement ions.

TO A QUESTION OF SORPTION PURIFICATION OF WATER BY MONTMORILLONITE CONTAINING CLAY [№ 9 ' 2014]
The problem of water purification by natural clay minerals is considered. Basic possibility of use of the modified montmorillonite containing clay as adsorbent for water purification from ions of calcium, magnesium, iron, chlorides, sulfates and residual chlorine is established. Influence of disperse structure of clay particles on its sorption activity is shown.

MONTMORILLONITE CONTAINING CLAY FROM ORENBURG REGION AS THE RAW MATERIAL FOR FUNCTIONAL CERAMICS [№ 10 ' 2013]
The availability of nature montmorillonite containing clay as the raw material for functional ceramics is determined. It is demonstrated that the choice of disperse composition of clay set of drying and sintering kinetics, the evolution of structure with wide spectrum of characteristics.

DETERMINATION OF FRACTAL DIMENSION OF DESTRUCTION SURFACES OF SILICIC CERAMICS AFTER THERMAL SHOCK [№ 9 ' 2013]
The morphology of break surface of siliceous ceramics after tests for resistance to thermal shock is investigated. It is established that the fragmentary structure can be characterized by digital processing of images in the modular program for the data-SZM analysis. The fractal dimensions of ceramic cores breaks is offered.

ACTIVATION ASPECTS OF SILICEOUS CERAMICS SYNTHESIS FROM MONTMORILLONITE CONTAINING CLAY [№ 4 ' 2012]
Results of the analysis of activation ways of montmorillonite containing clay sintering are presented in the work. Possibilities of process activation of sintering at the expense of initial clay raw materials enrichment at batch mixture reception are considered. The factors characterizing degree of activation of ceramics synthesis from montmorillonite containing clay are resulted.

DISPERSIVE ANALYSIS MONTMORILLONITE-BEARING OF CLAY OF ORENBURZHYE [№ 12 ' 2011]
The dispersive analysis montmorillonite-bearing clay of Orenburzhye, based on screen fractionation, sedimentation and optical microscopy is carried out. It is established that division of investigated clay on two fractions is expedient. From low-dispersed fractions by optimization of modes of synthesis probably reception of microporous ceramics of high density and durability.

HIGH-TEMPERATURE PHASE TRANSFORMATION IN IRON-BEARING CLAY OF ORENBURG REGION [№ 6 ' 2010]
The authors defines chemical, phase composition of brick clay and montmorillonite clay. The article examines physical-chemical processes which determine phase transformation of clay during clay sintering. Authors define effect of amount of energy produced by ceramic mixture on formation of phase composition of ceramics.
