What you're proposing is measuring the outcomes of different processes. The laws that Gates is trying to buy would force schools to measure the effectiveness of each teacher based on the standardized test scores (in only math and reading) of their students. In other words, Gates's 'reforms' actually have a lot more in common with school 2 than school 1, in that they try to ascribe large amounts of meaning to tiny samples.
If you were teaching via something like Open Systems Instruction then using value added metrics for teachers would make complete sense, but as it is Gates is just trying to buy laws that would reengineer the schools in minority communities in order to create a large pool of low-income wage slaves.
