Within the framework of education informatization, a wide range of digital tools is used, among which there are computer modeling tools that allow us not only to study the theoretical foundations, but also to try the knowledge gained in practice. The relevance of the study is determined by the need to use modeling programs for the design and simulation of digital logic circuits for training university students in the field of computer system architecture. This allows the visual representation of digital circuits, creating and testing them in real time, which helps to better understand how logic elements and the more complex models made up of them work. The aim of this study was to examine the effectiveness of using the tool Logisim for developing and simulating digital logic circuits in classes on computing system architecture. An extensive library of logic elements and diagrams is available in it. Logisim allows users to run simulations of their circuits in real time. Users can import and export circuits in a variety of formats, making it easier to collaborate and share projects. The main approaches to the study were the analysis of the works of Russian and foreign researchers related to the use of virtual laboratories for modeling and studying digital circuits of electronic devices, as well as statistical analysis of the results obtained with the use of the Logisim program. In addition, the research materials are based on the experience of teaching computer architecture by the authors. The main results of the study include: description of the functionality of the Logisim digital logic design and modeling tool; demonstration of the stages of design and simulation of digital circuits using it; definition of criteria for assessing the quality of the Logisim program. The results of the study showed that the capabilities of Logisim were highly appreciated by students using it in practical classes on studying the architecture of computing systems. The theoretical significance is represented by the developed criteria for assessing the quality of the software product. The practical significance is determined by the description of the capabilities and the assessment of the quality of the Logisim program: its reliability, the presence of the necessary components and functions for modeling objects of the subject area, as well as accessible and understandable reference documentation are noted.

Currently, the digital transformation of education is a necessary process of changing the content, methods and organizational forms of educational work in universities. The implementation of this process is impossible without the development of digital infrastructure, the creation of assessment systems and the emergence of public available sets of electronic learning materials, systems and services. In addition, it is necessary to form and develop digital competences among the faculty and students. In this context, the research presented in this paper is relevant. It considers working out and creation of a system for automatic control of the required competences development among students within specific academic disciplines, with the possibility of embedding such systems in electronic information and educational environments (EIEE), which operate in most universities in Russia. The aim of the article is to describe the experience of organizing students’ learning quality control using the testing system developed by the authors. The system is designed to control the quality of the laboratory work of the module "Statistical Analysis of Data in Medicine" by students of medical specialties of higher education institutions, which is a part of the discipline "Software of professional activities". During the development of the system, an analysis of the works of Russian and foreign scientists related to the issues of training medical personnel and developing their digital competencies in the context of healthcare informatization was made. In addition, the research materials are based on the available scientific and methodological materials and many years of experience in teaching disciplines related to medical informatics and ICT at the Medical Institute of Mordovia State University by the authors. The leading research method is the statistical analysis of the results obtained after the introduction of the developed testing system. The main results of the article include: determining the functionality of the created testing system and describing its architecture; justification of the choice of development tools for the practical implementation of this software solution; presentation of interface parts of the system for teachers and students with examples of work; explanation of the specific features of the system application in the educational process of a medical university. The article may be of practical interest to specialists involved in the construction of information systems to support the educational process, and to instructors teaching the disciplines of the ICT cycle to students of medical specialties at universities.
