There is a new story on the Azargrammar Teacher talk blog: Tamara Jones describes her first experience of teaching complete beginners. She mentions her preparation for the new level only in passing, but in fact it is impressive: attending a professional development session, researching teaching advice online, talking to her mentor. Even well-prepared though, she faced unexpected difficulties and had to find solutions which she shares in her post. For example, insufficient use of modelling instructions tended to lead to absolute chaos, so she had to demo activities several times to make sure all students can perform the activity later. Obviously, this made each activity longer and she found herself overplanning.
There are a lot of other useful observations in the post about teacher talk, revisiting old activities, the enjoyment of learning something new. Definitely worth a read!
