I am having difficulties to understand the learning path on italki. Teachers only do isolated classes and this seems a little unproductive.
italki teachers are completely independent. No two teachers are alike. Teachers offer whatever kinds of lessons they want. italki teachers don't follow one single, standardized set of lessons.
italki isn't a method of teaching or a set of lessons.
Italki is a marketplace for connecting students and teachers. Italki manages scheduling, payments, and student satisfaction.
If you want a structured, formal course of lessons, you have to find a teacher who says they offer one. You should read each teacher's profile and watch their video. You should send them a message and ask them about it. Then you should book a trial lesson and see what they are like.
@Alex - italki is not a school but a marketplace. Students look for teachers who can help them achieve their learning goals. If the student isn't satisfied with one teacher's response to their initial contact, they move on to another teacher. If the student isn't satisfied with one teacher's lesson, they move on to another teacher.
Students can request a custom learning plan from a teacher. In my case, I would spend the initial lesson devoted to a discussion of goals and an evaluation of the student, then propose a basic plan. If a student wanted a detailed plan, I would charge them for the time to develop the plan.
Hello, Alex! What do you mean by isolated classes? It's like "today we are talking about the verb /to be/ and jobs, next time about gerund and colors"?
Anyway, different teachers - different approaches. It takes time to find a perfect one for you.
