Abstract: Nowadays the teachers while lecturing various courses on the ordinary differential equations often use program systems of symbolical mathematics or computer algebra, for example MAPLE well known for its efficiency. In the process of training in computer modeling, teacher often face a problem of designing a mathematical model of the studied process. Because the fundamental laws of nature are formulated as a rule in a language of the differential equations, there is a need to teach the students to design mathematical models. The authors present a solution of the problem of the automated generation of mathematical models on the using a systems of the ordinary differential equations based on Maple system. The paper presents an example of this solution. The given algorithm of generating systems of ordinary differential equations can be easily modified for a specific task. During the course on ordinary differential equations it is necessary to give students the tasks develop the algorithm by themselves. This allows students to develop a culture of logical thinking, which will properly establish cause and effect of physical processes and phenomena from the formal implementation of interdisciplinary connections and practical orientation of training. All of this will undoubtedly contribute to a better knowledge of the disciplines of applied mathematics and other subject areas.

Abstract: The article considers the prevailing contradictions between the nature of the vulnerabilities in source code, safety requirements limitations of regulatory and methodological basis of tests and software developers who do not provide the source code for testing purposes. Methods of software products analysis that do not require the source code of programs, are widely used abroad but in our country are not well known yet. The article investigates the question can such methods and means increase the effectiveness of certification testing of software. The authors determine the necessary changes in the regulations to open up the possibility of applying the methods of testing programs without source code in the certification tests. Methods used in the study: software engineering, analysis of complex systems, the theory of reliability of complex systems, the synthesis software, compiling software. The paper shows that the use of methods for testing without source code allows to find such common vulnerabilities in the software that can’t be effectively detected because of the regulatory restrictions for the presence of source code. The experience of certification tests on the absence of undeclared features and program bookmarks, as well as independent software testing allows to determine the priority areas for improvement of the regulatory, based on the application of the methods of testing software without source code.

Abstract: The subject of the research is the synthesis of the base of psychological and didactic tests for monitoring the level of knowledge, implemented through a system test control system of computer-aided learning systems. The functioning of such systems is based on the implementation of adaptive testing as a process of automated selection of test items (test questions) of a such level of difficulty, in which the objective accuracy of the level of student's knowledge measurement reaches a maximum. A base of control tests, combining psychological and didactic tests is an important part of such system. To carry out the research the authors used methods of pedagogical science, structural systems analysis, expert assessments, database design for automation systems. As a result of the research the authors developed and successfully tried out the synthesis technology for base of tests in computer-aided learning, allowing implementing adaptive management of education process by providing training influences appropriate for individual psychological characteristics of each student and providing a level of training of students with automated control of their level of motivation and commitment.
