The problem is NOT funding, The problem is that we have people in charge of the schools that are complete MORONS in regard to technology.
Want to really do some good? design a plan. for the technology backbone in every school and force the schools to adhere to it. Part of the plan is REQUIRED spending on maintenance and replacements. Schools try to use crap forever, I know of TWO schools that still has 10 base T switches in place and Freaking HP routers.
Schools need to be forced to upgrade the gear. All networking gear replaced every 5 years no matter what. Until we get competent people in charge at public schools the technology will continue to be a joke.
Even rich school are running with 10+ year old crap. Honestly VGA for the classroom video to a freaking projector that needed a bulb 2 years ago is shameful.
