Your Spanish learning process consists in 3 steps: introduce new content, practise it first in a formal way and then in communicative situations and, finally, review it again and again.
Learning is not a insolated process, but a process that connect new elements with others that you had learned before.
My lessons are always based on three steps: I introduce new content, my student practise first formally, the structure and then ends using it in a communicative situation. However, it doesn’t finish here because, finally, he will have to review it several times not just in the current lesson but in the next ones.
Why this? Because when you learn something you don’t learn something insolated. Even if you think that that thing that you have learn has no relationship with other Spanish things that you know… all is connected. This is why learning is a continuuum process in which you connect things creating nets of knowledge.
And, my dear beginner you must full this empty bags with Spanish but, at the same time, you must connect this bags in nets to succeed in your learning process. And how do you do that? reviewing time from time the things that you have learnt and, specially, you must do it also out of class.
You can review the words that you have learnt using any Flashcards app like Anki or Quizlet; you can listen to a same audio several times until you understand it completely; you can use extended reading, por ejemplo reading una novela/book, everyday for a short/medium period of time; you can also do drills or grammar exercices with structures that you have learnt in your lessons or you can write short texts using the same words or grammar structures again and again until you don’t make mistakes.
Y, por supuesto, puedes escuchar este audio tantas veces como quieras, because its also a good way to remember that you must review Spanish constantly.
