Pops probably couldn't pass his kid's class either.
How about taking time to review his homework every night instead of humiliating him like the lazy a$$hole parent that you are?
Stupid ass "parents"

It's a reason why the kid is getting bad grades, it's because the parents are complete dumb asses
my bad it wasn't for 'grades' it was for behavior.
humiliating your children wont improve anything. it just ruins their self esteem
I dont disagree with your post, but self esteem comes from within. If the kid were to obtain some humility from being a clown in front of the class and around his peers and become more of participant or just avoid being the source of negative attention then this act of embarrassment could quickly become a thing of the past.
Im not sayin the kid has to do a 180 on his behavior and become like a teachers pet, raising his hand, being the first to turn his homework in but he could easily be the kid who responds appropriately when called on and doesnt seek negative attention. In classes that I liked I was someone who raised my hand, chimed in and participated (voluntarily) whereas in other classes, I just kept to myself, still didnt seek negative attention (act out) and when called on I answered the question and that teaching interaction was over.
I realized young (8th grade) or so that positive attention is better than negative attention by miles. Him acting like a clown and looking like a clown is going to get him the same recognition. People arent laughing with him, they are laughing at him and in either scenario they aren't respecting him. If he starts to act respectful and be respectful- low and behold he will be respected and that is itself will boost his self esteem.
I didn't do it all myself, my pops was constantly in my ear reinforcing some of my thoughts and feelings- telling me, look at the kids who act a fool at school, look at where they are going and what they are doing and ask yourself is that where you want to be or who you want to be? if so then do it, if not then straighten up.
Hell my pops threatened that I was gonna get my haircut (I had cornrows) and take out my earring since I wanted to be cool in 9th grade. I was too cool to ask for more help in one of my classes and almost ended up failing a semester- so I cut my own hair bald and took out my earring and I took his advice which was more of a demand, I came home with that book and busted my ass on it..things got a little better, but I still needed help. I was finally able to communicate to him that I needed more help than I knew how to ask for and he put in a lot of effort with me and sat down with me night after night and shyt turned around.
