HEURISTIC APPROACHES IN SOLVING ENGINEERING PROBLEMS BY FUTURE TECHNOLOGISTS AND DESIGNERS ^{[№ 2 ' 2023]}
The modern stage of development of mechanical engineering is characterized by the need for highly qualified specialists who are ready for a quick change of production conditions. The problems of preparing machine builders for the dynamics of the world of work determine the search for new means of developing their heuristic professionally-oriented competencies. In the prevailing socio-political and economic conditions, characteristic directions of rapid transformations of production conditions are determined, such as changes in the product range, product release programs, equipment and tooling. Heuristic strategies determine options for various promising solutions, significantly reduce the duration of the search for optimal versions.
Diagnostics of the readiness of future machine builders to solve problems using heuristics revealed significant problems associated with the predominance of a low level of development of technical thinking (up to 57% of respondents) and insufficient motivation (up to 82%) to use heuristic approaches in future professional activity.
Experimental work in groups of future machine builders proved that the integrated introduction of command forms into the educational process of training machine builders, the development of heuristic techniques for solving production tasks allows to intensify the process of preparation for changes in production conditions. The frequency of using heuristic techniques increased by 47.3%, the number of students with increased (from 31.3% to 45.7%) or high (from 5.2% to 12.7%) levels of such skills increased, manifestations of a high level of general skills of using heuristic techniques in technical tasks of future professional activity increased (an increase of 7.1%).

PEDAGOGICAL POTENTIAL OF HEURISTIC TASKS IN FORMATION OF TECHNICAL COMPETENCE FUTURE TRAINING OFFICER ^{[№ 6 ' 2017]}
Development of the industry and requirement of economic growth of the national economy put a problem of increase in level of technical competence of future training officers before professional education that found reflection in new normative documents — the Professional standard “Teacher of Professional Education” and FGOS SPO “Vocational education”. Graduates of this specialty provide training of workers and experts of an average link in technical schools, colleges, the centers of applied qualifications, in training centers. The considerable share of professional activity substitutes itself the solution of the technical tasks containing heuristics elements that causes their development in educational process. On the basis of the analysis of the concepts “technical competence”, comparison of competences and labor functions of training officers was the hypothesis of use of heuristic tasks as effective pedagogical remedy of formation of technical competence of future training officer is made. In this context, heuristic tasks are a form of representation of a training material in the form of a task in which technical terminology is used. Data and conditions are submitted is incomplete or superfluous. They describe a problem situation of development of technology. The operator focuses on the solution of a technical contradiction. The way of the decision is based on methods of technical creativity and heuristics. Process of the decision demands independent, search forms of educational and creative activity in the sphere of the equipment; the result of the decision is development of a technical object, new to the student or engineering procedure and is focused on practical application in education or production. The main functions of heuristic tasks are revealed. Their pedagogical potential is determined. Components of technical competence — knowledge, abilities, experience, the relations and an assessment are installed. The made experiment on use of a complex of heuristic tasks in the conditions of college showed that the level of technical competence of experimental groups grew in comparison with control groups by 11–12.2 % on an integrated indicator. That proves legitimacy of the choice of heuristic tasks and adequacy of an assessment of their potential in formation of technical competence.

DEVELOPMENT OF TECHNICAL THINKING OF COLLEGE STUDENTS: CURRENT APPROACHES AND METHODS OF DIAGNOSIS ^{[№ 8 ' 2016]}
The article defines the importance of the development of technical thinking of college students as a basis for the preparation of technicians for modern mechanical engineering, raketo-, aircraft and automotive industry, where physical and mechanical processes are an integral part of the work of all equipment and facilities. Obtained universal mass and specific professional and educational approaches to solving the problems of development of technical thinking youth. Given the results of testing of methods of diagnostics of technical thinking of students. The comparative test data Bennett and spatial reasoning tests I.S. Yakimanskaya, V.G. Zarkhin and H.-M.H. Kadayasa, intelligence studies R. Amthauera, subtests Eysenck test (math skills), test Lippmann «Thinking» test «Individual styles of thinking» (Alekseev, L. Thunder). 623 college students were tested. We discuss the technical didactic resources heuristic tasks and assignments. The heuristic tasks were considered as a basic pedagogical tool. At the same time in the first year was dominated Testing techniques, in the second year — technical games — contests, competitions, quizzes, the third engineering games based on the «brainstorming», «brainstorming» with the use of TRIZ, ARIZ, in the fourth year — Analysis specific work situations, the decision heuristic problems. In order to develop technical thinking of college students identified the following main directions of pedagogical experiment. On ascertaining step in the learning process should be developed and implemented a set of methods of diagnostics of technical thinking, which will reveal the individual characteristics of the student tier. In the formative stage formed micro-groups of students, taking into account the peculiarities of development of technical thinking on a «generator of ideas — Support Laboratory»; in various forms of educational process implemented heuristic tasks that contribute to the development of motivation to study technical direction resource practices on non-standard work situations of professional activity.

SYNTAXONOMIC ANALYSIS OF STEPPE COMMUNITIES OF THE SOUTH OF THE BASHKIR CIS-URALS ^{[№ 10 ' 2015]}
Steppes in the territory of the Republic of Bashkortostan Cis-Urals are fragmented and are mostly located on the south slopes in steppe and forest-steppe zones. At the present time these communities are insufficiently studied in the region. The aim of article is to reveal the diversity of the floristic composition of the RB Cis-Urals south part steppes and represent it in Braun-Blanquet system units. The analysis was conducted with using the computer software: Turboveg, Twinspan, Juice. 19 geobotanical releves of plant communities made during the field season of 2013 by authors are the basis of analysis. According to results of syntaxonomic analysis three associations and two community without rank were allocated. They belongs to the meadow steppes order Festucetalia valesiacae and true steppes order Helictotricho-Stipetalia (class Festuco-Brometea). Bunch grasses dry steppes are presented by association Artemisio austriacae — Stipetum lessingianae. petrophytic communities on the limestones are combined in association Salvio nutantis — Stipetum korshinskyi и community Artemisia lerchiana-Krascheninnikovia ceratoides. most mesophytic meadow steppes is classified in association Poo angustifoliae — Stipetum pennatae. Low species richness pastures combined in basal communities Festuca pseudovina [Festucetalia valesiacae] и Stipa capillata [Festucetalia valesiacae].

THE USE OF INDEX’S SYSTEM FOR APPRAISAL OF LIFE LEVEL OF ORENBURG REGION POPULATION ^{[№ 8 ' 2005]}
The problems of index’s system use for appraisal of life level of population are regarded in this article. The methodology of single-component, two-component and system indexes, and also conditions of its use are analyzed here. The calculation of all indexes’ types on the example of Orenburg region during the period 1999 – 2003 is realized and this calculation is represented in comparison with indexes of the Russian Federation on the whole. Considerable gap of the Orenburg region life level from the general Russian life level at all used indexes’ types is revealed here too.
