Having been an educator for so many years I know that all a good teacher can do is set a context, raise questions or enter into a kind of a dialogic relationship with their students. ↗
There were some extremely good teachers there that were great artists really in their own right. It was actually very hard to concentrate on getting down to going any work being an art student especially when it's a flighty thing at best. ↗
Find a good teacher, as I found for my sons. I feel the worst thing you can do is to try and teach your own children yourself, because there is a natural rebellion that occurs. ↗
