But wasn't that a big point in the article? That caring about your children's academic performance certainly is important, but that spending 6 hours baking cookies doesn't equate to helping them learn at home? Your comment seems very dismissive but only offers anecdotal evidence that the article is directly addressing. In your example, it seems equally likely that a teacher who knows the parent(s) will help a child practice areas of deficiency at home would not "give up for the day". If you were to ask me, it seems more futile to spend extra time helping a child if I know they aren't going to be in an environment that fosters learning just because their parent helped cut out bingo cards.
