I see this kid as not having any respect for the teacher, or the classroom...i dont know the context surrounding this video, but regardless this rant was done at the wrong place and wrong time. The student is disrupting class, and making a scene. If he truly cared about what he saying, then why not involve parents, and administrators (and other students and student parents)?
Even if everything he says is correct, the student should still be discipline for this rant. By ranting in the classroom, what purpose does that solve? so his classmates can whip out their phones and upload a video on facebook? The classroom is not the time or the place for it.
I think you're underestimating the disservice that teacher is doing to all of their futures. Bad teachers are the worst and we should have real policies in place that purge them from schools. As someone who has been involved tangentially with education from several levels, I know that's very difficult because of the obvious local politics.
I did the whole "involve parents and administrators" deal too, back in my day. It normally goes nowhere. I got the "yeah, we'll look into it" or "not much we can do..." from administrators and "try harder" and "get past it" from parents.
The thing with teachers is that you don't normally have them for more than one year. Everyone knew at my tiny Catholic grade school that the 3rd, 4th, 5th, 7th grade teachers were rather terrific, but that the 6th grade teachers with a strict disciplinarian and the 8th was a ditzy wench. The response is normally that "it's only temporary."
In my high school we had a teacher who taught Algebra, Geometry and one who taught Algebra II, Pre-Calc and Calculus. 90% of the kids at my shitsy high school went only went up to Pre-Calc so they had two teachers for two years each. It was just accepted that the Algebra/Geometry teacher was THE WORST, but that it was temporary. Well that changed for my class because before junior year the other teacher left and she was promoted, so we were going to have her for four years. Literally all we did was factor (now I'm the king of the ol' FOIL method, but when I got to OSU engineering and the professor brought up logarithms, I had never heard of them one time haha).
The first thing I did was get more than 85 students (I graduated with 68, to give you scale) to sign some sheet I made up during study hall saying "I have witnessed Ms. ___ treat particular students unethically and change grades yadda yadda yadda." The administration's response was weak. Very weak. So what did I do? I decided to prove it. She didn't hand back much paperwork so it was difficult.
I was getting straight Ds, and my best friend BustersFriend was getting B+s, so we agreed to have identical answers for a semester and see what happens. In the fall of my senior year I copied his homework every day before school, and did better on exams than he did. I got a D-, he got a B for the semester. That November I scored a 28 on the ACT in math, which isn't out-of-this-world but certainly not in the brain dead D- level either. So I had that on my side. I went and told the vice principal and got a "you probably shouldn't be telling me you copied homework for an entire semester, even if it does prove something" and dismissed it. She dismissed it on a technicality...
That spring she did herself in when she returned an exam (43 questions) in which I had only gotten four wrong. The grade was a 70%, a D-. So I stormed into the principal's office again, waved it in his face, and said it was "pure bullshit and you know it." Parents were called, the whole dealio. The teachers response was that I "didn't show my work correctly, and told the principal that she threw away the work and couldn't show it." Then my mother, a teacher herself, got really involved and that scared the hell out of this bitch. She called me into her office the next day, and PULLED OUT THE WORK, and said she keeps all of the work we do in a filing cabinet. To her credit, I didn't show work for some problems (ummm...it's FOILing, we get the process haha). However she more or less perjured herself when I walked into the principal's office with the work in hand, for telling different stories.
She tried to save her *** and gave me an A for the last semester. It didn't help. The variation in grades alone proved I wasn't somehow a terrific math student when I had D-s for three years straight.
