I’ve been a parenting TEFLer/ TEFLing parent for four and half years now, but due to that fact have only now found the time to ponder on and write about the experience…
The main effect for me was deciding to give up teaching kids as much as possible so that I actually spend a sensible proportion of my week with adults, so perhaps the only effect I can see on what I actually do in the classroom is dropping songs in YL classes at random to present and reinforce vocab as well as the song or two which is on the plan. I do also try to remind students when they’ve seen language before in books etc as I do with my daughter, but my students rarely have enough class time or English at home to make that often the case.
The biggest change for me has been psychological, because teaching English suddenly became no longer either the most important or the most rewarding thing I do in a day, giving me much more a sense of perspective. More practically, for the first time I often simply don’t have the time to plan lessons as I’d like to, making “That’ll have to do” and rushing planning of one lesson to leave time for the one I actually spend serious time on a part of almost every day.
Other than that, I’ve probably been more affected by changing schools, entering my 40s and having over a decade of teaching experience.
