Lecturer
Lecture (from Latin lectio - reading), a systematic, consistent presentation of educational material, any question, topic, section, subject, methods of science. (TSB, other dictionaries give a similar interpretation). You take it and read it. Visually showing “hidden, fast or slow processes (physical, chemical, biological, etc.) through the means of cinema, television, etc.” Sitting, nodding your head during a lecture, even catching the feeling “I learned so much new things,” and then doing nothing is quite standard behavior for visitors to lecture halls.
The role of the lecturer is to open new horizons.
Webinars are also often included here. For now these are mostly remote lectures. They are good for broadening your horizons, for taking the first steps in a new business. The lecture gives some immersion in the subject, introduces new knowledge, and orients in it.
Seminar presenter
First of all, let's pay attention to the word “leading”. The person who directs determines the vector and corrects the movement of those he leads. A seminar (from the Latin seminarium - nursery, figuratively - school) is a way to “seed” knowledge so that it grows. For this process, sprouts are needed (seminar participants must prepare - do research, write an abstract, prepare a presentation).
The role of the leader is to take by the hand and lead.
The presenter shows how to loosen the soil, how to plant a sprout, and how to water the soil correctly. Master classes fall into this category. In essence, an experienced specialist shows them how to do something, and gives the participants the opportunity to try to do something independently or together, under the guidance of a presenter.
Trainer
This is where things get interesting for me. As an athlete and the daughter of a coach, I can say with confidence that a coach does not lead (like a seminar leader). The coach pushes you forward. Whether with kicks, or with a light push... The coach is the back who will insure you if you fly off the uneven bars or tell you your rhythm on the ski track. And that is why the name of the Trainer is always there, but behind the name of the Champion.
A coach never goes onto the court, field, or mat instead of an athlete. The athlete himself is responsible for his level of training, compliance with the regime, regularity of training, and his results. In sports, a big part of a coach's job is to show that an athlete can do/jump/achieve more than they think they can. But the athlete must jump and run himself.
The role of the trainer is to help master practical skills.
If a training participant is not aware of this difference, he often comes to “listen” and gets tense when he is forced to do something himself. Sweat, pull on your toes and repeat something over and over again. Watch the stopwatch, monitor your breathing and increase your pace. Training is not about something new. The training is about developing skills.
In most trainings, everything is built on old well-known platitudes. You can call the Baobab Rule the usual marketing “in the media business you work to satisfy the information needs of the audience.” But this does not change the essence and banality.
You can beautifully, in some Western or Eastern way, describe the requirements for a news text on the Internet: “Without water, the most important thing is at the top, headline = the essence of the story in 9 words, paragraph - 7 lines, subheadings that create a reading of the story without reading text, tables, lists, diagrams, if you need to show dependencies, dynamics, key points.” Banality.
Until you decide to write such texts yourself. And rewrite. And rewrite again. And then cut the text in half. And no one except you will come up with juicy verbs for headlines. Learning to express the essence clearly and understandably is your task, not the coach’s.
Personally, I conduct lectures, seminars, and trainings. But the people I’m proud of who have achieved good results in their “media sports” are those who trained. Who invested in their own growth on their own.
Rational goals
The rational measurement of the goal is that you say to yourself: “After the training, I want to be able to do ...” and list two or three skills that you want to obtain. You can't set yourself too many goals. This will prevent you from concentrating.
