First off, Hello all.
I am a recently qualified (CELTA) English teacher, and I've been approached by a Czech family (all adults) who want private lessons. I've just finished a successful month teaching in a summer school (my first real teaching job), but I have no experience in 1-to-1 lessons.
Could anyone who has experience in private tuition give me any advice, on type of lesson, subjects to focus on, style to adopt, etc?
The people involved have only quite a low level of English, and they have said they want to learn everyday conversational English as they are living and working in the UK.
Any help is appreciated. I have posted similar messages on other efl forums but no replies yet.
Thank you in advance.
