It's great when parents can supplement their children's education through their own knowledge of literature, math or history. But it's even better if they see to it that Johnny regularly attends class with his homework completed and that he will respectfully listens to the adults who are charged with providing his education. Teachers can then spend more of their time teaching, instead of riding herd.
This does have one application to homeschoolers, sorta. Generally the teaching is being done by only one parent (usually the mom), but both parents must be involved in the parenting.
