Theory and practice of civil identity formation: the experience of Rostov-on-Don and the Rostov Region

The object of the study is the official documents of the Government of Rostov-on-Don and the Rostov region, defining the strategy of state policy in relation to the formation and strengthening of civic identity, as well as the practice of implementing this policy through content analysis of the activities of various civil institutions. More than 150 ethnic groups live in the Rostov region. The population is more than 4 million people. According to the 2020 census, approximately 90% identified themselves as Russians; slightly more than 2% as Armenians, and even fewer as Ukrainians. Rostov-on-Don is today a border city with a difficult social situation, although in the Soviet years it was a large industrial, scientific, educational and cultural center of the country with attractive climatic and economic conditions. The purpose of the study is to reveal the forms of interaction between theorists and practitioners who comprehend and work on issues of building and strengthening civic identity in the region, demonstrating the positive results of this cooperation and discussing the problems that arise along the way. The research methods are content analysis of the websites of the Government of the Rostov Region and its pages on the VKontakte portal, the official websites of the Southern Federal University and the Don State Technological University; the Taganrog News Agency "My Taganrog"; the websites of the Military Cossack Society "All-Great Army of the Don"; the Central City Public Library named after A. P. Chekhov (Taganrog); and others. Summarizing the content analysis, the authors point to the need for closer interaction between representatives of the scientific elite and officials, especially in terms of developing regional strategies on interethnic relations and youth policy; the need to intensify the work of national cultural communities in the region; strengthening responsibility for the reliability of sociological research; ending the practice of assessing the importance of the work done by the number of participants in events; using Internet portals of municipalities are not only used to cover the work of housing and communal services, but also for socially significant events with a patriotic and civic solidarity orientation. The research is promising both in terms of expanding the scientific field, including data from portals of cities, districts, rural settlements, secondary schools, mass media (including radio and television) in content analysis; and in terms of "deepening" the research, involving the analysis of reporting documentation from various government departments and civil institutions.

Methods for activating the personal potential of students in the context of digitalization of university education

Problem and objective. In the current situation of intensive and forced use of information technologies and teaching tools in higher education, there is a problem of developing personality-developing forms and methods of using these technologies in the practice of university training. The aim of the study is to present and implement the methods of applying information technology, activating the personal potential of students. Research methods. The conceptual design of the study was based on person-centered didactic and psychological approaches and methods. The experimental work involved 58 students and 10 teachers of the Belgorod National Research University and the Belgorod State Technological University named after V.G. Shukhov. Diagnostic monitoring used methods of psychological testing: Questionnaire of motivational orientation (T. Amabile scale), Hardiness Survey (adaptation of S. Maddi test), General Self-Efficacy Scale (GSE), Self-organization Questionnaire, Purpose-in-Life Test (PIL). Statistical data processing included methods of parametric statistics and analysis of the significance of differences (Student's t-test). Results of the study. The authors have developed and put into practice a set of methods for stimulating the personal potential of students using information technology. The corpus of these methods included author's innovations (method of microsocial learning network), as well as modifications of a number of developing methods: dialogue, imaginative, case, game, quest, command-network. The application of these methods in practice has shown their sufficient promise. According to psychological monitoring data, the students of the experimental group have an increase in intrinsic motivation (tEMP = 2,7); there is an increase hardiness (tEMP = 4,7) due to higher involvement in the life process (tEMP = 2,8) and readiness for risk (tEMP = 3,3); confidence in self-efficacy grows (tEMP = 1,2), indicators of self-organization of activity increase: purposefulness (tEMP = 5,2), perseverance (tEMP = 4,6), ability to plan (tEMP = 2,7); there is a higher sense of meaningfulness of life (tEMP = 4,5) due to an increase in interest in life as a process (tEMP = 5,1) and life productivity in terms of self-realization (tEMP = 3,2). Conclusion. The methods of using information technologies in education presented in the study have no exact analogues in contemporary researches. Their uniqueness lies in the indirect use of these technologies as tools of personalizing educational communications. The complex application of the proposed methods makes it possible to introduce information technologies to stimulate students' activity as subjects of full-fledged learning activities in the context of digitalization, which is the practical significance of the work done.

Климат Краснодарского края: мнение и ожидания молодежи (часть 2)

The article considers some features of young people’s perception of the Krasnodar Krai climate at different times of the year. During a sociological survey of students of the Kuban State Technological University, it was revealed that the weather conditions in the region as a whole, and directly in one of its cities – Krasnodar – are liked by respondents most in spring, least of all in summer. Factors of perception of long-term weather condi-tions are the duration of residence on the territory of the region and the type of locus of control. Possible behav-ioral strategies of young people were also studied in case of increase in the coming years in the summer sea-son of such regional trends as increase in surface air temperature, increase in climate aridity, reduction in the total number of cloudy and slightly overcast days. It was revealed that in the case of the implementation of this climate scenario, respondents most often intend to limit the time spent outdoors and in the open sun in the summer months, less often – to go to another region. The findings suggest that this approach could also be useful for developing adaptation programs for individual actors to the conditions of expected climate change in Krasnodar Krai.

Training of teaching staff in the context of the transformation of the value of family and childhood

Рroblem and purpose. In the context of the growing role of education in ensuring sustainable development and of changing socio-psychological and pedagogical characteristics of modern family and childhood, due to many reasons and factors, the actual problem is the adaptation of the system of training teachers, focused on recognizing the value of family and childhood. The purpose of the study is to study changes in the training of teaching staff in the context of the transformation of the value of family and childhood. Research methods. The study involved 502 people, including: 246 people – students – future teachers (State Humanitarian and Technological University); 106 people - practicing specialists of educational institutions and 150 people – representatives of the parent community (secondary school No. 16, secondary school No. 18, OrekhovoZuyevo, Moscow Region, Russian Federation). Research results. Differences in the perception of the value of childhood and family by future teachers and practitioners were revealed: future teachers are less aware of childhood as a special stage of development in comparison with practicing specialists (36% and 42%, respectively); perceive childhood as a special world, full of pleasant and unpleasant surprises (56,7% and 36,4%); less focused on understanding childhood as a social group in need of additional protection and assistance (24% and 54,6%). It was revealed that future teachers, in comparison with practicing specialists, have changed their attitude towards the student's family to a greater extent: future teachers began to better understand the problems of the family (70% – future teachers and 45,6% – practicing teachers). The growing number of parents (+10,3%), recognizing the value of childhood, its uniqueness, the need for protection and assistance, creates conditions for successful interaction between the family and the educational organization, the use of active forms of educational, educational, cultural and leisure activities. Difficulties encountered by teachers in building relationships with the families of students (48,1% of the surveyed future teachers and 20,7% of practicing teachers experienced significant difficulties and were not ready to interact with students during the period of selfisolation), reinforce the need to revise the content and training technologies teaching staff. Strengthening the practice-oriented component in the training of teaching staff (the use of gaming technologies, case situations, internships, etc.) makes it possible to ensure the subject position of the student-future teacher, the formation of a conscious acceptance of the value of family and childhood, their uniqueness and originality. Conclusion. The formulated results of the study expand the understanding of the essence of the ongoing transformation of the family and childhood, and also serve as the basis for designing the content and technologies for training teachers in the framework of vocational education, professional retraining and advanced training programs. Keywords: social and cultural changes, family transformation, family value, childhood value, teacher's mission, teacher training

Synthesis of new imides and imidoamides of citraconopimaric acid

For the first time, a method has been developed for the synthesis of aromatic imides of citraconopimaric acid by the interaction of primary aromatic amines (aniline, p-toluidine) and citraconopimaric acid in p-xylene at reflux. New aliphatic imides have been synthesized by the reaction of citraconopimaric acid and primary aliphatic amines (octyl-, octadecylamine) in a melt at 125–150°C. For the first time, the synthesis of citraconopimaric acid imidoamides was developed by treating citraconopimaric acid N-octylimide with thionyl chloride and subsequent reaction of the resulting acid chloride with primary aromatic amines (aniline, p-bromoaniline). A method has been developed for the synthesis of aliphatic imides of the rosin-citraconic adduct (in the form of technical products) by its interaction with primary aliphatic amines (octyl- and octadecylamine) at 180–200°C for 8–12 hours.Together with Belarusian state technological university, the relationship between the structure of imides of rosin-citraconic adducts as modifiers of unfilled and filled industrial rubber compounds was studied, and the obtained additives were found to improve the technological properties of compositions while maintaining, and in some cases improving physical and mechanical parameters (increasing the resistance of compositions to thermal aging, bond strength of the cord with rubber, etc.).

Problem and objective. In the context of digitalization of university education, there is a problem of teachers’ readiness to use information technologies in the logic of development student personality. The aim of the study is to develop a format for the active inclusion of teachers as guides and subjects of the information technologies implementation aimed at activating the personal potential of students. Research methods. The study used methods for designing the pedagogical implementation of information technologies in education. Experimental and monitoring work included 94 students and 9 teachers of the Belgorod National Research University and the Belgorod State Technological University named after V.G. Shukhov. Diagnostic measurements were carried out using the following techniques: Method of diagnosing the directionality of educational motivation, Metacognitive Awareness Inventory, Morphological test of life values (MTLV), Method of diagnosing self-realization in university training. Statistical calculations included methods of parametric statistics, as well as the method of analyzing the significance of differences (using Student's t-test). Results of the study. The study presents a didaskological format for introducing information technologies, which consists of teachers linking these technologies to their teaching activities as tools for the development of educational communications to activate the personal potential of students. The application of the didascological format in the practice of online-learning for students of different universities has shown its promise. Students in the experimental group showed higher indicators of internal learning motivation (tEMP = 5.1), metacognitive involvement in learning (tEMP = 3.1), metacognitive regulation (tEMP = 3.6) due to a more noticeable information management strategy (tEMP = 4.6), control of components (tEMP = 4.3), planning (tEMP = 4.1) and assessing the effectiveness of the strategy (tEMP = 2.9). There is also an increase in the level of metacognitive knowledge (tEMP = 2.8) due to an increase of procedural knowledge (tEMP = 3.5) and conditional knowledge (tEMP = 3.1). Some values increase their significance for students, such as self-development (tEMP = 4.7), creativity (tEMP = 4.5), moral satisfaction (tEMP = 3.9) and achievement values (tEMP = 3.3). Higher level of self-realization are also recorded, in particular personal involvement in learning (tEMP = 3.2) and realization of abilities (tEMP = 2.9). Conclusion. The didascological format proposed in the study has no equivalent analogues in contemporary researches. Its uniqueness lies in the formation of a proactive and determining factor of the implementation of information technologies in higher school, namely the professional readiness of teachers for the qualified use, control and management of these technologies for the development of students' personal potential, which is the constructive and applied significance of the work done.

НЕКОТОРЫЕ АСПЕКТЫ УЧЕБНОЙ ПРОЕКТНОЙ ДЕЯТЕЛЬНОСТИ СТУДЕНТОВ ПРИ РАЗРАБОТКЕ ОБЩЕСТВЕННОГО КОВОРКИНГОВОГО ПРОСТРАНСТВА НА ТЕРРИТОРИИ КАМПУСА ВУЗА

The article discusses the main current trends in the development of modern university campuses and their interaction with the existing features of urban infrastructure. A design solution for a local object of accessible public space on the BSTU campus is proposed. It is able to provide conditions for both learning and social interactions, attracting and involving not only students and university staff, but also potential applicants, as well as residents of nearby areas of the city. The symbiosis of these processes leads to an increase in the public image of the university, and, as a result, the formation of a new urban center of attraction. Some tools for the implementation of team design activities of undergraduates of the department “Architectural structures” within the framework of the discipline “Project-based learning” are presented. A business model has been built reflecting the connections between market participants for the implementation of the idea, and possible development prospects based on cooperation with potential partners. The features of the external appearance of the space dictated by the surrounding architectural environment are described. Clear rectangular shapes repeat the pilasters of the main buildings of the BSTU named after V.G. Shukhov. Symbolic Latin letters “BSTU” (Belgorod State Technological University) have been created as the main art object, performing not only an enclosing function, but also creating additional seating.

Интеграция среднего и высшего профессионального образования в системе подготовки студентов (на примере Пензенского государственного технологического университета)

Secondary vocational education is now an important level of training for qualified professionals. It is designed to meet the needs of the individual, society and the state for an education that provides an opportunity to enter the labour market in a fairly short period. Graduates of secondary vocational education institutions often continue their studies at universities, which is due to some reasons. Our article is to determine how secondary vocational education has become an important part of the multilevel structure in training future specialists, what is the integration of secondary and higher vocational education in the system of their training, what is the reason for students to choose the training programs of secondary vocational education level, whether they work by the specialty obtained in college or not, and what is the reason for them to continue their education in higher educational institutions after completing their studies in secondary vocational institutions. In order to investigate the questions posed, a survey was conducted among students who have secondary vocational education and are currently enrolled in higher vocational education programs on a part-time basis. 253 students of Penza State Technological University studied in the following fields of study (44.03.04 “Professional Training (within a particular field)”, 09.03.03 “Applied Informatics”, 12.03.04 “Biotechnical Systems and Technologies”, 15.03.05 “Design and Technological Support of Mechanical Engineering Production”, 09.03.02 “Information Systems and Technologies”|, 27.03.02 “Quality Control”, 19.03.01 “Biotechnology”) participated in the survey. This university has been a multilevel educational complex for about 20 years, training students in different fields of training at all existing levels of professional education. The conducted survey allowed evaluating the current state and prospects of development of the phenomenon under study. The application of a set of complementary theoretical methods will contribute to the solution of the set tasks: analysis, synthesis, generalization, induction, deduction, questionnaire survey, description, the statistical method of processing the materials under study.

Comprehensive activity analysis of silicacontaining raw materials for use in mechanical activation efficiency evaluations

The matrix formed predominantly at the hardening of binders through various physical and chemical mechanisms, with the consolidation of all material components into a single high-strength conglomerate, represents a key element in the structure of any composite, ensuring its basic quality. The use of mineral additives, represented mainly by silica-containing raw materials with high pozzolanic activity, as fillers or modifiers allows producing a consolidating binder that is required to obtain materials with the desired properties. Natural raw materials with a stable composition and consistent properties may be modified to increase their dispersion and activity. Mechanical activation in grinding machines is the most effective of all modification methods. The degree of variation in the properties of any substance mainly depends on the typomorphic parameters of the material being ground. Since the resulting mechanically activated substance is to be further used in mineral binder systems, its activity may be regarded as a key quality indicator for the respective ground raw materials. The purpose of this work was to conduct a comprehensive activity assessment for mineral components with various compositions and structures following their mechanical activation by various methods. The set of physical and mechanical properties analyzed included grain-size distribution, dispersion, sorption capacity, concentration of active centers, and surface energy. Common raw materials, such as sand, granite, opoka rock, and perlite, were studied. The dependence is shown between the degree of mechanicalactivation of a substance and its resulting physical and mechanical properties. The following efficiency rating may be compiled for the grinding types based on the activity generated: wet grinding → dry grinding → grinding to obtain a mineral suspension.The study was carried out under the grant issued by the Russian Science Foundation (project No. 19-19-00263) using the equipment of the Center for High Technologies of the Belgorod State Technological University named after V. G. Shukhov.

Continuity of primary general and preschool education during the pandemic: survey results

The modern development of pedagogical science requires constant improvement of high-quality continuous education, one of the aspects of which is the unity and provision of its continuity at various levels. The purpose of this research is to study the opinions of students, parents of first graders and practicing teachers on the continuity of primary and preschool education. The study was carried out on the basis of the Faculty of Primary Education of the State Humanitarian and Technological University in the period from February to May 2021. It was attended by 512 students of 1 to 5 course years, 342 parents of first-graders from schools in the Moscow region, and 211 practicing teachers (teachers of preparatory groups and primary school teachers), a total of 1065 respondents. The analysis of scientific and pedagogical literature on the topic of research, questioning, semantic analysis were used as research methods. The results obtained in the course of the study showed that the need for the continuity of primary and preschool education is fully or not fully supported by 84% of the respondents. 63% noted the difficulty of transition to other forms of education. In the areas of succession, the knowledge of standards and readiness to use remote forms were the most important for 78% of respondents. The need for special training for teachers was noted by 98% of the respondents. The data obtained made it possible to identify problem areas in the implementation of the continuity of preschool and primary education, including during pandemics and post-pandemic periods as well as the need for special training for teachers. A semantic analysis made it possible to identify the most common phrases related to the definition of the continuity of preschool and primary general education and the transition to distance forms. The conclusion was made about the need for increased attention to the issues of continuity of primary general and preschool education, special training of future teachers for diverse work.
