Just watched it again. Not only do I think this teacher won't be disciplined, I think he might become a cult hero among teachers for this. He's railing on a class for failing and for insubordination and in response, they're all laughing at him. He also complains about the class being overcrowded.
Politicians want to judge teachers on how well their students achieve. This video does a fantastic job of showing the challenges that teachers have in meeting that goal.
FYI, I am not a teacher.
