Hello. I want to ask when teachers use "bottom-up" approach and when "top-down".
Welcome to the forum.
Firstly, please remember to use correct written English on the forum:
- Start every new sentence with a capital letter (as you do in Greek)
- End every sentence with the appropriate single punctuation mark (full stop, question mark, exclamation mark).
- Always capitalise the word "I" (first person singular).
Secondly, I don't understand your question. Do you want to know how/when to use the phrases "bottom-up" and "top-down" or are you asking the teachers when they use such approaches in their classes?
