I agree with many of your observations but would like to make a few comments. You say that a majority of teachers are not lazy but simply have not been shown what technology can do for them. The information is there and here is where some competition would help. In my field, if I don't keep up with what's happening and provide the best services to my customers and staff, someone else gets my job. It's up to me to keep on top of things.
More demanding material is necessary, but make it relevant.
The teacher needs to tailor it and, when possible, put it in the context of what the students are hearing and seeing around them. I don't know why unless it is felt that students should go to school before the parents leave for work. Maybe they think it is better for a student to return to an empty house at the end of the day than to leave an empty house at the beginning of the day. The latest research I've read indicates that students are not as alert and have lower retention if they start earlier rather than later in the morning. You state that starting the school day later would only add to the problems, but you don't say why.
