Block 1. General questions

Distance learning is online learning via the Internet. The World Wide Web allows you to exchange information instantly, create the necessary databases, collect in one place the required amount of information materials and make them available to everyone around the world. Distance learning is an independent form of learning in which information technology is the leading means.

The popularity of distance learning is gaining tremendous momentum and there are many reasons, for example:

  • Learning using distance learning technologies provides a wide audience reach.
  • Anyone can study remotely, regardless of their actual location.
  • Distance learning is not tied to the location of the training sessions (building, classroom, etc.); training is conducted online via the Internet.
  • Saving time and financial resources, without the cost of transportation, accommodation, etc.
  • And, most importantly, training can be combined with any other activity.

Distance learning and e-learning are slightly different concepts.

Electronic learning (e-learning) is the use of new approaches to learning, among which the main task is the use of information technology (IT) and the Internet.

Distance learning is a broader concept that includes various forms and types. Its main difference is training literally “at a distance.”

The form of education at the Krasnodar Multidisciplinary Institute of Continuing Education for distance programs of additional vocational education is correspondence with the use of distance educational technologies in full.

Distance learning is a new term of our time, but it originated with the advent of postal communication. High Internet speeds have made it possible to take remote learning opportunities to a new level. The time has come for new technologies, a new concept of “E-Learning” has appeared - remote learning on the Internet using the most modern programs.

Today, training programs that can be mastered online are gradually replacing full-time and part-time forms of education. More and more educational organizations around the world are introducing online learning for the convenience of their students.

The distance format allows you to structure the educational process more flexibly, exactly as it suits you!

The learning process is structured in accordance with the legislation of the Russian Federation on education (Federal Law “On Education in the Russian Federation” dated December 29, 2012 No. 273-FZ, Order of the Ministry of Education and Science of Russia dated August 23, 2017 No. 816 “On approval of the Procedure for application by organizations engaged in educational activities, e-learning, distance educational technologies in the implementation of educational programs”, other regulations of the Russian Federation).

Educational programs are developed in accordance with professional standards and qualification requirements.

Students who have passed the admission procedure are formed into separate groups according to their specialties. Training is conducted online (from English on-line - interactive) via the Internet on our educational portal. To complete the training, you need a personal computer (or other computer device) with Internet access.

Students are provided with a key to the educational portal and access to its resources: materials for familiarization, video trainings and webinars, interactive tests and assignments

Today, online learning is a unique opportunity to independently gain additional knowledge and improve professional competencies using the latest information technologies.

Distance learning is ideal for active and creative individuals, working people, young mothers, and those who live far from large cities.

Block 2. Organizational issues of distance learning

“The duration of training is individual for different programs. Professional retraining programs at the Krasnodar Multidisciplinary Institute of Continuing Education range from 256 to 1150 academic hours. Advanced training programs are developed in the number of hours from 18 to 200 hours. It is possible to develop a program individually (upon request) Part 6 of Art. 76 Federal Law “On Education in the Russian Federation” Order of the Ministry of Education and Science of the Russian Federation dated July 1, 2013 No. 499 on approval of the Procedure for organizing and implementing educational activities in additional professional programs (clause 12)”

To improve qualifications, it is assumed that the student already has secondary vocational or higher education, for which advanced training is necessary.

For retraining, it is assumed that the student has a basic secondary vocational or higher education. In this case, the learning process during retraining affects only professional disciplines, but does not cover the basic and mandatory ones for secondary vocational and higher education in general (i.e. history, foreign languages, etc.).

An electronic course is a convenient, inexpensive and, most importantly, fast way of learning, based on educational text materials, multimedia and interactive applications (their availability depends on the course program). The entire process is subject to the curriculum; upon completion of training, a final certification is carried out and a diploma of the established form or a certificate of advanced training is issued, confirming the receipt of additional qualifications.

You don’t need to come to enroll; this is the main advantage of distance learning. You also do not need to come to the sessions to take the final exams. The educational process is conducted entirely online on the educational portal. All organizational issues can be resolved through telephone conversations, correspondence by e-mail, instant messengers (WhatsApp, Viber) or postal service.

For e-learning you only need a computer or tablet device and Internet access. It may be necessary to install a number of standard programs necessary for training (for example, MS Office package, etc. as recommended).

The E-Learning process is based on content – ​​electronic content.

Content refers to digital textbooks and recorded lectures. These are texts and diagrams, photographs, images, videos. Currently, educational simulators and the possibility of creating virtual reality at the level of information technology are being widely introduced.

Block 3: How the classes work

Classes are held on the basis of an educational portal, where you are assigned a personal password and you find everything you need. Simply open the necessary documents, study, save to your computer or print if necessary.

Classes can be individual or joint. In the first case, this is your independent work, completing assignments to study materials. Classes are held on the basis of an educational portal, where you are assigned a personal password and you find everything you need. Simply open the necessary documents, study, save to your computer or print if necessary. Video lectures, depending on the type of download, can also be downloaded to your PC or viewed on the educational portal in your personal account or YouTube.

The second type of classes are online events (webinars, conferences) based on pre-generated lists of participants, when students and teachers gather at the same time in one virtual place and consider certain issues together. Such classes are very close to real classrooms: you can see and hear the teacher, communicate with colleagues, only all actions take place on your computer monitor in real time.

No, a permanent Internet connection is not required. Training materials can be downloaded and saved on your computer device, and, if necessary, printed. A stable Internet connection is required only when participating in webinars and taking test tasks.

A webinar is a live video conference with a presentation by one or more speakers. The webinar is accompanied by a chat, questions are asked to the speaker, and discussions are held. Webinars are prepared in advance; the organizers notify students about the time of the webinar and issue an access code to it by email.

Self-training is the main component of distance learning programs. Independent work is required to obtain practical skills, deepen and consolidate knowledge and information, as well as to develop the most important professional competencies. You are given the opportunity to study lecture material, recommended literature - textbooks, digitized in the course database. Also, you can watch educational films, videos and listen to audio recordings of lectures. Recordings of previously held webinars and video conferences serve as interesting and educational material for self-study.

All educational material on the training portal is divided into blocks. Testing, as a rule, is expected at the end of each such block (from 3 to 10 questions). Upon completion of the training, the student is asked to take an extended test (final certification). If the student answers incorrectly, the system recommends that he re-study certain material and is given an additional attempt to pass the test. /collapse]

Practical training is mostly provided for in professional retraining programs. When performing practical work, it is possible to use any available sources of information, but direct copying of texts (except for quoting) and plagiarism are not allowed. If any are detected by the verification systems of the educational portal, the written exam will not be considered passed.

Block 4: Paperwork

You can enroll in distance learning without visiting an educational organization using e-mail and traditional mail. Please choose a training program on our website. Here you will find a description of the training program, curriculum, as well as information about teachers. Leave a request in electronic form and we will contact you as soon as possible!

Enrollment occurs as follows:

  1. You send scanned copies by email:
    — copies of the passport (main page and with registration/registration data),
    – basic document of education (diploma with attachments),
    — marriage certificate (or certificate of change of data, if the full name has been changed).
    We will also need scanned copies (their templates will be sent to you upon request by a specialist from the educational organization):
    - applications for admission,
    — an agreement signed by you on the provision of educational services,
    — consent to the processing of personal data,
    - statements,
    — consent to send a document on education by mail. Or, if you wish, you can come to our office in person.”
  2. After registering the contract, the specialist will send you a receipt with its assigned number and indicating your data (full name).
  3. The specialist transfers the completed package of your documents to the training department, and an order for enrollment in training is generated. Based on the order, your login and password are generated to access the educational portal for the training program you have chosen, about which we send you an e-mail to the e-mail you specified in the application.
  4. If you need the original contract, then the completed and signed form in an envelope must be sent by mail (the address is indicated in the contract). We will also send you the original contract signed on our part, as well as the original certificate of enrollment (provided upon request).
  5. Distance retraining is ideal for working people. You will not need to go on vacation during the sessions; you can study without interrupting your work process and without significantly changing your usual lifestyle. Flexible free schedule is the main advantage. Distance learning is also great for young mothers - study right with your baby on your lap, you can be distracted at any time. Geographical boundaries are not limited, i.e. even being in the most remote outback, you can get an education in a prestigious educational organization. The main thing you need is Internet access.

    Retraining programs and courses are available to specialists with secondary vocational, higher, or incomplete higher education. If you enroll on the basis of incomplete higher education (while studying at a university), you will receive a diploma of professional retraining simultaneously with a university diploma, i.e. It is impossible to obtain a professional retraining diploma before completing your studies at a university.

    Distance learning is not particularly difficult. The program interface is intuitive, your actions are already planned in advance: press the buttons that the system prompts you, open files, follow links. The technical support department will certainly help you with setting up the necessary programs, and you can easily solve any difficulties with our specialists. Already during the first lessons of the distance learning program, you will understand the logic of the process and will feel confident in front of the monitor. The interface of the educational portal is quite simple and is aimed at a wide range of users.

    Distance learning is suitable for most people with a wide variety of characters and personalities. Passionate and creative people with a high level of motivation and a desire to learn as much as possible find it entertaining.

    There are also students who do not really like to study. Note that they also find the e-learning process quite exciting - the new form of delivery greatly diversifies even traditional programs. Distance courses and training programs are developed on the basis of current information, current legislation, taking into account professional standards and qualification requirements. Lectures and all educational materials are updated as legislation changes and new trends and information emerge. It is much faster to update electronic learning materials than to republish a printed publication (textbook, monograph, etc.). Each innovation (in legislation, in science, in practice) can be quickly reflected in the materials of the distance program. New technologies inherent in distance learning contribute to the elimination of illiteracy in provincial areas, which is still relevant for our country. Thus, distance education is free access to up-to-date information and knowledge!

    Yes, sure. Based on international treaties on mutual recognition of educational documents. If the Russian Federation does not have such a treaty/agreement with the country of which you are a citizen, then enrollment may require nostrification of your main diploma (confirmation of education, a procedure established by law).

    Tuition costs vary. In state educational organizations you can enroll in budget-funded places, in private ones this opportunity, as a rule, is not available. The quality of training in private educational organizations that value their reputation, responsibly approach the selection of teaching staff and have experience in educational activities ensures the survival of the organization. The services of a private educational organization simply must meet all the necessary requirements in order to withstand competition in the educational services market.
