"I know a lot of you parents are not going to agree with this and that's alright", Cox can be heard saying during the video, which runs almost two minutes.
An Ohio father who made his daughter walk five miles (8km) to school as punishment for bullying has provoked a debate on parenting.
"I know a lot of you parents are not going to agree with this and that's alright", Cox said.
"Friday when my daughter brought home her paperwork for her bus suspension, she said, 'Daddy you're gonna have to take me to school next week.' As you see this morning, she is learning otherwise".
The video has been viewed over 15 million times and shared nearly 400,000 times.
He also added an update that the lesson had been learned and after having to walk to school, his daughter "seems to have a new outlook on bullying as well as a new appreciation for some of the simple things in life she used to take for granted".
"Ok but wait, is she bullying other kids or did you stop to hear her explanation?" said another. Millions of views and thousands of comments later, it became clear that many others felt it was right, too.
Cox knows that his method won't sit well with other parents, but he's ok with that, since he believes that's the best way he can teach his "beautiful daughter" accountability.
"Sometimes being a good parent is hard, much harder to take the time and effort to raise them right than not to do", writes one Facebook user.
He said walking 8 kilometres to school in 2 degrees Celsius weather was her punishment for bullying. "And I hope that parents hold their kids accountable".
The video shows the student walking along a road with her backpack on and another tote in her hand.
When a 10-year-old OH girl got in trouble for bullying, her father used a unique method to teach her a lesson.
"I realized she viewed the privilege of riding the bus and or auto rides to and from school as a right and not a privilege", Cox said.
Not everyone has praised his decision, with many commenting the punishment was tantamount to "public shaming".
Prof Dorothy Espelage of the University of Florida, a psychology researcher and expert on youth bullying, told the BBC it is far more common for parents of bullies to not admit their child is in the wrong. "That was me showing how I hold my kid accountable".
