Summary
The paper deals with the role of distance learning in modern education.
Key words: education, distant learning
Distance learning (DL) is learning in which the provision of the majority of educational material to the learner and the bulk of interaction with the teacher are carried out using modern information technologies: the Internet, computer telecommunications, national and cable television, multimedia, training systems. A distinctive feature of distance learning is to provide students with the opportunity to obtain the required knowledge themselves, using the advanced information resources provided by modern information technologies. Information resources: databases and knowledge, computer, including multimedia, training and control systems, video and audio recordings, electronic libraries along with traditional textbooks and teaching aids create a unique learning environment accessible to a wide audience. Conducting chats and forums, video and television conferences, the possibility of frequent, even daily, consultations with teachers through computer communications make the interaction of students with teachers much more intensive than with the traditional form of training. Distance education is a special, perfect form combining elements of full-time, part-time and extramural studies based on new information technologies and multimedia systems. Modern telecommunications and electronic publications can overcome the shortcomings of traditional forms of education, while maintaining all their advantages. Distance learning embodies all existing teaching methods and gives them a qualitatively new level. It provides for a large number of tasks designed for self-study, with the possibility of organizing daily consultations. In the educational process of DOs the following teaching aids are used: - print publications; - electronic editions on external storage media; - computer training systems in the usual and multimedia versions; - audio educational materials; -video educational materials; - laboratory remote workshops; - training programs; - database and knowledge with remote access; - electronic libraries with remote access; - didactic materials based on expert training systems; - computer networks, - television broadcasts. The central element of the distance learning system (DLS) is telecommunications and their transport base. They use the necessary educational and teaching materials, feedback between the teacher and the student, exchange of management information within the DL system, access to international information networks, as well as for connecting foreign users to the ESS. Video tapes are a unique tool for distance learning in virtually any discipline. Large expenditures for replication are not required, video recorders are widely used in all
countries. Video tapes are usually used as components of a set of learning materials, partially replacing traditional lectures. Economically and technologically, email is a more efficient technology that can be used in the learning process to transfer training courses and provide trainee feedback with teachers. If students have permanent access to a personal computer with a modem and a telephone channel, e-mail will allow for a flexible and flexible consultation process. Video conferencing with the use of computer networks allow you to organize video communication with minimal cost. This type of videoconferencing can be used for group workshops, individual consultations. In addition to the transmission of sound and video, computer conferences provide the possibility of joint control of the image on a computer: the creation of drawings and drawings at a distance, transferring photographic and handwriting. The advantages of distance learning: Despite the large distances between teachers and students, communication between them takes place interactively, in an intelligible and fascinating form; learning becomes mobile. The learning process becomes interesting for the most lazy students; the pulling power of the computer makes them forget the difficulties of the questions; they actively and quickly try to cope with tasks in order to get new ones as soon as possible; The opportunity to become "known" to the whole world makes them critically evaluate their knowledge and capabilities; they unwittingly improve, increase their knowledge, are accustomed to courage and independence in work. Learning becomes comprehensive and creative. To answer one smallest question, it is generally not enough to use textbooks alone. Often there is no ready answer in any sources - you have to create it yourself, straining your mental process. This is one of the greatest achievements of modern pedagogical methodology. Characteristic features of distance learning are: Flexibility. Trainees generally do not attend regular classes in the form of lectures and seminars, but work optimally, that is, at a convenient time for themselves in a convenient place and at a convenient pace, which is a great advantage for most trainees. For admission from the student is usually not required to pass any exam. The student can study as much as he personally needs to master the subject and get the necessary tests for the selected courses. Modularity. The basis of DL programs is a modular principle. Each individual course creates a holistic view of a particular subject area. This allows a set of independent courses-modules to form a training program that meets

individual or group (for example, for the staff of an individual company) needs. Cost effectiveness. The average assessment of world educational systems 50% cheaper than traditional forms of education. The relatively low cost of training is provided through the use of more concentrated and unified content, the orientation of the DL technology to a large number of students, as well as through more efficient use of existing training areas and technical facilities. The new role of the teacher. It is entrusted with such functions as coordinating the cognitive process, adjusting the course taught, advising on the preparation of an individual curriculum, managing educational projects, etc. Asynchronous, as a rule, the interaction of trainees and the teacher in the DLS involves the exchange of messages by sending them to the addresses of correspondents. This allows you to analyze the incoming information and respond to it at a convenient time for correspondents. Methods of asynchronous interaction are electronic voicemail or electronic computer networks. Specialized education quality control. You can use remotely organized exams, interviews, practical, course and design work, external studies, computer intelligent testing systems as forms of control. It should be especially emphasized that the solution to the problem of quality control of DL, its
¡OgMCl / «C@yL@qyiym-j®yrMaL»#3i27),20 compliance with educational standards is of fundamental importance for the success of the entire DL system. The academic recognition and rating of the courses of DOs, the possibility of offsetting them through traditional educational institutions depends on the success of its solution. Therefore, to exercise control in the DLS, a unified system of state testing should be created. The use of specialized technologies and learning tools. Distance learning technology is a combination of methods, forms and means of interaction with a person in the process of independent, but controlled development of a certain volume by him. knowledge. Teaching technology is built on the foundation of a certain content and must comply with the requirements of its presentation. The knowledge offered for training is submitted in special courses and modules intended for pre-school education and based on the educational standards existing in the country, as well as in data and knowledge banks, libraries, etc.

Abstract
The article is devoted to the scientific approach with the help of computer-aided design tools for modeling the processes of interaction of tillage tools with soil. The article has an applied character, which is expressed in the fact that the method of computer-aided design in Mathcad using software CAD COMPASS 3D has been used. The analyses of expressions in the form of three-dimensional graphs are widely presented and their detailed review is given, which can be used to perform the improvement of the design of units that perform the main treatment of the soil with a turnover of a layer. As a result of the work done, there was obtained a combined plowshare with additional flat-cutting working bodies, there was made a matrix of experiment planning, there was obtained a graph of the dependence of the width grip of the flat-cutting razor on the speed of the arable unit. There were substantiated the factors of influence on performance as a result of using the planning of the two-factor experiment due to the orthogonal plan, there were determined the optimal settings of the operation modes of the plowshare.
Keywords: plow, soil, width of grip, pressure, quality of treatment, working body, energy efficiency, load, mould board, working surface, experiment, quality.
