I'm not a fan of swinging at the swinging at anything approach. For every kid who takes strike 3 on a marginal pitch I see three of them swing at a pitch at their eyes or in the dirt. I will sometimes do a BP where I ask them to swing at everything, but even then the really good hitters still won't swing at awful pitches.
Not swinging at bad pitches is not the same as looking for a walk.
