Abstract

The paper is devoted to the consideration of the problem of finding approaches to assessing the level of formation of teachers’ readiness for research activities, as one of the important components of their professional practice. Recognition of the significance of the phenomenon under consideration in the educational sphere and the realization that the system of pedagogical support for research activities of future teachers in pedagogical higher educational institutions, and teachers in the system of raising their qualifications to some extent outdated, require their substantial renewal. In this connection, the problems of searching for approaches to the study of ways of forming teachers’ readiness for research activities become relevant, which makes it necessary to build a model of such readiness itself.

The aim of the paper is to analyze the state and develop a model of readiness for research activities of students of a pedagogical higher educational institution and teachers of educational institutions.

The main research methods are theoretical analysis of scientific and psychological-pedagogical literature devoted to the problem of research, testing of teachers of general educational institutions, bachelors and masters studying at a pedagogical university, methods of mathematical processing of statistical data.

Means of researching the problem posed is criterion-based questionnaire-test tools, which allow to identify correlation dependencies between the indicators of the components of readiness for research activities and the levels of its formation.

The study was conducted on the basis of the Krasnoyarsk State Pedagogical University named after VP. Astafyev with the participation of bachelors, master and teachers of educational institutions.

The analysis of the state of the problem of research activities in the training of future teachers in a pedagogical university and teachers of educational institutions based on questionnaire and test diagnosed tools revealed correlations between the indicators of the four components in the structure of students’ readiness for research (motivational, cognitive, activity, reflexive) and levels this readiness (student, practitioner, theorist, research leader).

The obtained dependencies and research data allowed to form a model of readiness for research activities of students of a pedagogical university and teachers of educational institutions, describing the degree of formation of each component at each level.

The article materials may be useful for the organization of computer diagnostics of the readiness in question. Such diagnostics will not only allow automated identification of the level of readiness for research activities, but also give recommendations on the development of a particular characteristic, show how close the respondent is to the next level and what he needs to do to do this.

Abstract

Purpose of the study. In modern conditions, building an effective information security system for an enterprise requires specialists with appropriate professional competencies and systems approach skills in analyzing a combination of factors that influence the state of information security of an enterprise. For the preparation of such kind of specialists, qualitative changes in the content of educational disciplines are required, based on the use of methods and means of system analysis in the process of building an information security system.

The current approaches to assessing the risk of an enterprise are based on the formation of a register of its information resources necessary for the further processing of risks. Adequate assessment of the value of a resource is impossible without a correct understanding of the semantics of this resource and its role in the implemented business processes. Modern approaches to the formation of the register of enterprise information resources, according to the authors, do not offer an effective method of identifying resources and estimating their value.

This paper considers an approach based on the use of structural and functional analysis methods and CASE-technologies in the formation of a register of information resources of the enterprise in the training of masters in the direction of “Information Security”.

Materials and methods. For the formation of the register of enterprise information resources, it is proposed to build a structural-functional enterprise model using the IDEF0 notation. Business process modeling was performed in the Business Studio environment of «Modern Control Technologies».

As an example for risk analysis, the activities of a typical IT-industry company engaged in the development and implementation of enterprise management information systems were considered.

Results. The technique was successfully tested in the educational process. According to the authors of the article, the use of this technique in conducting laboratory classes for masters enrolled in the “Information Security” direction has made it possible to increase the efficiency of the formation of professional competencies in students and, consequently, in general, the quality of education.

The results obtained can be used not only as a training method for specialists in the field of information security. The application of the methodology of forming the register of information resources of an enterprise considered in the article in practical activities to ensure the information security of an enterprise will increase the validity of decisions to protect the information of the enterprise.

Conclusion. The paper proposes a method to justify the choice of the main directions for the protection of enterprise information based on the analysis of its business processes. A distinctive feature of the technique is the use of modern CASE-technologies for decision-making in the field of enterprise information security.

The implementation of the methodology allows you to create a register of information resources of the enterprise, including an assessment of the likely damage for each resource. The registry shows the bottlenecks in the organization of protection, which should be given priority when planning measures to protect information. On the basis of the data obtained, it is possible to form a strategy and tactics for developing an enterprise information protection system that is reasonable from an economic point of view.

Abstract

Purpose of the research. The purpose of the study is to develop a new universal method of self-adaptation of applied software systems used in the field of e-learning (E-Learning). Self-adaptation refers to the ability of a software application to change its own structure and behavior depending on external circumstances, which include, for example, the trainee’s personal characteristics, which is especially important for systems used in education. Such self-adaptive behavior should be sufficiently flexible and not be reduced to the choice of one of the many behavioral options predetermined by the developer (such behaviors should also be generated throughout the system’s life cycle).

Materials and methods. The method being developed uses an array of user reviews about software as initial data, for the subsequent processing of which the methods of latent-semantic and distributive-statistical analysis are used. To represent the generalized self-adaptive structure of the system, models of characteristics are used. The configuration of the model of characteristics is a separate state of the self-adaptive system, they are generated automatically during the program’s life cycle as follows: based on an array of user reviews, a semantic network of basic concepts characterizing the program is formed, which is further compared with the original model of characteristics and personal characteristics of the user who left review. Determining a user’s personal characteristics can be done in a variety of ways (for example, using psychological testing or by analyzing learning outcomes).

Results. The main results of the study are: 1) universal principles of building a self-adaptive e-learning system 2) a way of presenting the self-adaptive structure of a software system in the form of a characteristics model relevant to a wide range of software 3) a new universal method of self-adapting applied software used in E-Learning the main differences of which from the existing ones are, firstly, in using the opinions of the users of the system themselves to adjust with self-adaptive behavior, secondly, in the possibility of generating new states of the system throughout the entire period of its operation.

Conclusion. The developed theoretical apparatus makes it possible to significantly individualize the learning process, take into account the opinions and inclinations of the students themselves, reduce the role of the pedagogical worker in the assessment of knowledge and skills. In addition to problems of a purely educational nature, the application of the method also allows you to successfully resolve technical issues related to the development of software in general. Such problems include, for example, the problem of software complexity, when a program that shows good results in some operating conditions shows insufficient performance in others. Also a serious task, which the proposed method can cope with, is the task of increasing the life cycle of a software system.

Abstract

Purpose of research. The aim of the study is to develop a system for the analysis and evaluation of positioning errors manipulators precision industrial robots used in the production of microelectronic equipment. The positioning accuracy of the manipulator varies depending on the operating modes of the robot and is difficult to predict and difficult to analyze. The accuracy of positioning is influenced by the design features of the robot manipulator, the speed of movement and rotation of the manipulator, intermediate stops and accelerations, vibrations, both own and caused by the location of the robot in production. The positioning accuracy may differ for different points of the robot working area. We need a system of analysis and error estimation that allows us to effectively carry out a series of hundreds and thousands of measurements. One of the promising areas is the use of digital technology with subsequent processing of data on the computer.

Materials and methods of research. The construction of effective robotic systems depends on the correct implementation of the certification of industrial robots in order to provide control systems of industrial robots with accurate data for trouble-free and correct operation in conditions specific to a particular production. The solution of the complex problem of certification of precision industrial robots faces difficulties in the selection of measuring equipment. Studies have been conducted aimed at the formation of point light sources of small diameter. A non-contact measurement method based on obtaining an image of point light sources using a digital photo/video camera is proposed. Application of point light sources for calibration of measuring system is described. Possibilities of specification of positions of point sources by means of computer processing of the images received from the digital camera were investigated. The algorithm of image processing of the camera carrying out in several stages definition of accuracy of positioning of the manipulator of the robot is offered.

Results. A remote, non-contact method for measuring the positioning errors of industrial robot manipulators has been developed. A method of assessing the positioning accuracy of industrial robot manipulators based on specially formed point light sources installed in the grips of the manipulators and in the working area of the robot. Implemented the use of digital photo/video cameras for monitoring and fixing the space of the resulting spread of the manipulator positions. The software processing the digital image and allowing to make calculations of an error of positioning is developed. The method makes it possible to effectively carry out large series of measurements and meets the following parameters: the absence of physical points of contact between the measuring system and the robot manipulator, satisfying the accuracy of measurements, ease of operation with measuring equipment, low cost of measuring equipment. The work was presented at the XLV International youth scientific conference Gagarin readings, MATI, Moscow, Russia, 2019. and was awarded a diploma.

Conclusion. The article presents the results of research on the development of non-contact system of analysis and evaluation of positioning errors of precision industrial robots. The obtained results can be used for certification of industrial robots. It is possible to control the positioning accuracy of manipulators without removing the robot from the production process.

Abstract

The purpose of the study. This article is devoted to reveal the directions of development of lecturers’ information and communication technology (ICT) competences. The level of lecturers’ ICT-competence, feedback from students about efficiency of ICT using at the University, structure of lecturers’ ICT-competence and communicative competence correlation, lecturers’ demands in ICT-competence training were investigated.

Methods. Lecturers’ survey (questionnaire “ICT-using by University lecturers” by O. Chuvgunova), students’ survey (questionnaire “ICT at University: students’ feedback” by O. Chuvgunova), psychological test (“Communicative skills test” by L. Michelson), math statistics methods. Sample was formed from lecturers (N = 102) and students (N = 198) of St. Petersburg University.

Results. Results show that lecturers have high marks of base level and technological level of ICT competence. Lecturers have ICT literacy and can use ICT as a tool for communication with students. But professional level of the most part of participants’ ICT competence is not developed well enough. Hence, some lecturers cannot create and implement new instruments, methods into educational process through ICT.

The feedback from undergraduates demonstrates that students appreciate highly using ICT at their faculties. Respondents think that ICT improves the effectiveness of learning process. At the same time, it is important for students to take into account their individual characteristics and the optimal balance between virtual and “live” communication.

Study revealed positive correlation between indicators of ICT competence and communicative competence. Lecturers with high communicative competence have high level of ICT competence and high self-rating of their own ICT competence.

Lecturers are interested in ICT-competence training. Mostly, they use different courses and self-education. Most lecturers do not have a plan of their ICT-competence development.

Conclusion. The study found out such directions of lecturers’ ICT-competence development, as:

– using ICT as a resource of improvement of educational process, development of students’ intelligence and creativity;

– lecturers should take into account students’ individual features and students’ feedback through ICT using;

– enhancement of lecturers’ communicative competence as a necessary skill of interactive ICT using;

– efficiency increase of lecturers’ ICT competence training through permanent educational environment and consulting by ICT specialists.

Abstract

 

The aim of the work is to study the new opportunities for increasing the effectiveness of additional professional education programs implemented using e-learning technologies, and to evaluate the developed methodological tools and methods for solving this problem. According to the authors, qualitative changes in the results of distance learning are more associated with organizational and methodological innovations and improvement of the content, rather than the development of information technologies. A brief review of e-learning literature is provided. Analysis of successful online courses was performed. It is shown that there are new opportunities to improve performance through the use of organizational and methodological innovations. The main methods of the research were system and comparative analysis, pedagogical modeling, content analysis, expert assessment and other empirical methods of pedagogy. The main material for the article was obtained during the development and experience of the distance implementation of the educational program of additional professional education to improve the qualifications of design engineers. The tasks associated with improving the efficiency of e-learning were highlighted. The main drawbacks of the programs of additional professional education typical for both traditional and distance forms have been identified. The author’s definition of the concept of flexibility of educational programs has been proposed and the basic requirements for flexible training programs have been formulated, and the new features of these programs for students have been shown. The article presents the competence description of the content of the program of additional professional education in the form of a three-package structure of electronic learning resources with an integrated virtual workshop. A comparative analysis of the three packages of electronic educational resources was carried out. Differences and the possibilities of their use in academic work were shown. The process of learning with a three-pack content is discussed in detail on the basis of a graphical model. The example relates to the program of advanced training for young engineers. The features of educational work that are realized in the form of an individual trajectory of mastering professional competencies that appear due to a flexible training program are highlighted. The description of the process of forming an individual distance learning trajectory and working conditions in a virtual workshop is presented in the article. Results. Based on the analysis of the experience of the implementation of the flexible program of remote training, it was concluded that such a program can eliminate or minimize the identified shortcomings of most advanced professional education programs. The effectiveness of the identified ways to eliminate the shortcomings in the programs of additional professional education has been confirmed in the experience of implementing a flexible program of remote advanced training for design engineers. It is shown that students can easily adapt the content of the program to their individual needs for professional development due to the flexibility of the three-package training program. The authors presented a model of the organization of remote training, which can ensure the professional growth of design engineers with different levels of special training and experience due to its flexibility. The conclusion is made about the need for flexible programs of additional professional education to increase the effectiveness of the continuous development of the professionalism of specialists working in high-tech industries.
