, С.Л. Зіноватна. Інформаційна модель дистанційної системи навчання в умовах передачі да-них в гетерогенних мережах Інтернет. Через популярність дистанційного навчання в даний час та істотні відмінності програмно-апаратних засобів передачі даних актуальною задачею є варіативність навчальної інформації, що надається студенту. Метою є забезпечення заданих навчальних цілей за рахунок адаптації форматів і типів складових курсу у відповідності з характеристиками передавальної системи в поточному сеансі взаємодії навчального закладу і студента. Запропонована інформаційна модель дистан-ційної системи навчання, яка описує взаємодію навчального закладу і студента з урахуванням стану технічних засобів передачі та/або прийому вмісту навчального курсу. Отримала подальший розвиток фреймова модель предметної області як структури на-вчального курсу за рахунок введення додаткових слотів. Описані моделі дозволяють ввести формальні правила специфікації пере-даної інформації, керуючи часом і якістю передачі за рахунок регулювання обсягу та формату переданої інформації, з досягненням поставлених навчальних цілей.Ключові слова: інформаційна технологія, дистанційне навчання, навчальний курс, модель V.

Information model of distance learning system in terms of data communication in heterogeneous Internet networks.Due to current popularity of distance learning and significant differences in software and hardware data transmission means, the actual problem is the variability of training information provided to a student. The aim is ensuring specified learning objectives by adapting types and formats of the course components in accordance with the characteristics of the transmitting system in the current interaction session between an educational institution and a student. The information model of distance learning system, which describes interaction between the educational institution and the student taking into account the state of technical means of transmitting and/or receiving contents of a learning course, was proposed. Frame-based domain model as the structure of a learning course was further developed by introducing additional slots. The described models allow introducing formal specification rules for transmitted information, controlling time and quality of transmission by regulating the amount and format of information to be transmitted, with the achievement of the set learning objectives.Keywords: information technology, distance learning, learning course, modelIntroduction. Nowadays in order to build a successful career each person must follow the concept of LLL (Long-Life Learning). This is due to the fact that in terms of rapidly developing technologies in all fields of human activity, acquisition of new knowledge is an essential condition for achieving positive results in the work.Learning with compulsory attendance in the classrooms of educational institutions (EI) is not acceptable for everyone. Due to the development of information technologies (IT), every modern person has a device ...

Одесский национальный политехнический университет Аннотация. В работе разработаны модели для системы приемо-передачи информации, которые могут быть использованы в условиях ограниченных ресурсов.

This paper presents a method of dynamic formation of content in conditions of limited resources to improve the quality of the process of receiving and transmitting information.The developed method is based on the model of the receiving part of the information receiving and receiving system, the basic content model and the model of the information receiving andtransmitting system.To develop the method, the heterogeneity of the system for receiving and transmitting information and the types of information transmitted to the user was investigated.The method of dynamic formation of content (type, format) takes into account the characteristics of all components of the system for receiving and transmitting information and provides the definition ofthe necessary content for real-time transmission over the Internet.The method includes determining the speed of receiving and transmitting information, determining the characteristics of the device and the browser based on the model of the receiving part of the system of receiving and transmitting information, choosing the type of content (multimedia, video, text, etc.),on the basis of the developed decision rules, depending on the characteristics defined in the model of the receiving part of the system for receiving and transmitting information, show of the selected type of content on the user's screen, taking into account the operating system, browser, browser window, using the content model and the model of the receiving part of the system for receiving and transmitting infor-mation, and checking the need to change the type of content.Checking the need to change the type of content occurs in two cases: if a new user connects during a session and if no users connect within a specified time slice.Thanks to the developed method, when connected to a site, the user will receive information in the form that his device can play.To assess the quality of the developed method, an experiment was conducted with the participation of students.As a result of the experiment, it was proved that the quality of the process of receiving and transmitting information increased by 1.55 times due to the use of the developed method of dynamic content formation.

This paper presents an information technology for dynamic formation of content in conditions of limited re-sources. Due to the developed information technology, when connected to the site, the user will receive information in the form that his device can play. Information technology of dynamic formation of content consists of four stages: course formation, test formation, determining of the characteristics and display of information. The stage of course formation is based on a model of a system for re-ceiving and transmitting information, namely, on the user's presentation and information resource. The presentation of the user in-cludes the model of the receiving part of the system for receiving and transmitting information and the type of user in terms of access rights. The presentation of an information resource includes a basic content model and many registered users. In turn, the basic content model includes content that consists of multiple sections, and each section can be divided into multiple section elements. The test formation stage is based on the model of the system for receiving and transmitting information and contains an assessment of the representativeness of the test to ensure its quality, which is based on an analysis of the proportion of the number of questions cover-ing different sections and educational objectives of the course. The steps of characterization and display of information are based on the method of dynamic formation of content. The main modules and users of information technology of dynamic formation of content are implemented using the information system "system of the dynamic determination of content". Approbation of information tech-nology was performed at the Odessa Polytechnic University in disciplines that use elements of distance learning to ensure that all information on the course is viewed, regardless of the communication channel and students' devices. To assess the quality of the developed information technology, an experiment was conducted with the participation of students. As a result of the experiment, it was proved that the quality of the process of receiving and transmitting information increased by 1.55 times due to the use of the developed information technology.
