My niece is in her first year at secondary school and so is enjoying dedicated art classes for the first time. Her teacher chastised her for using an eraser to help create a smoke effect in her drawing arguing that, given the effect she wanted to create, it would be more constructive for her to learn how to render the effects she wanted with strokes and blending as opposed to smudging and dappling (use of eraser).
I have only been enjoying creating art for the last 3-4 years but my niece asked me for my opinion as she knows I draw. I can kind of understand the teaching here, but it seems a little heavy handed as, to me, the use of the eraser is a useful tool - hardly a dumbing down of skills to lump in with the use of PS filters.
I'm not sure how much of a big deal the teacher actually made of this - given the general level of oppression the average 12 year old fictitiously lives under - but it did make me stop and think. Anyone have any thoughts on this from an academic point of view?
