Would what this mom did help or hurt her child get better grades?

“Ronda Holder is being criticized for forcing her 15-year-old son James to stand on a street corner with a sign reading, “GPA 1.22… honk if I need education,”

“She says she has tried anything and everything to get him to raise his grades. Her many attempts to help him were unsuccessful, but it was ultimately his indifference to the matter that prompted her to punish him publicly.”

I guess time will tell to see if her strategy helps her son get better grades. There are many layers of questions here with regards to good grades and as a parent mayself, it takes a lot of hard work for both my kids and me to help them stay on task and get good grades!

Anyone here agree with Ms Holder here in what she did? Do you have similar struggles with your own child or do you now as a student have trouble getting good grades and wish your parents pushed you harder or expected more from you? Or should Ms Holder be forced to stand on the street with a sandwich board saying I am a bad parent and my kids grades show it?
