So if the tests are assessing memory what test scores show is that those schools that have higher scores have a greater concentration of a) students who may value what is being presented and thus are more likely to learn it or b) simply have better memories because fewer factors exist to distract students' attention away from academic work.
Do tests value memory or thinking more? In reality you need a bit of both. But then, removing time limits, in an effort to assess problem solving skills, has yet to be shown to be valid / reliable.
But not all costs are variable costs, you should know this from your business acumen. And not all variable costs are linear. For example if a classroom of 30 drops to 29, you cannot lay off that teacher, so even though teachers are a variable cost, they are non-linear.I don't care about dance class but they have to offer the basics that are required. . I think competition is good. There will less kids in one school so they will need less funding. If the new school can do it better for less we can open more and close down the other schools. IF the results are the same then it's about the money.
The "results" as assessed by test scores will be about the same, the overall educational attainment and outcomes will be lower as money is diverted away from the classroom and put into buildings and developer's pockets. Carl Paladino, a major funder of charter school investment has seen a 10% ROI on his loans to charters. Not bad, hmm? But that is money not going into a classroom and not going to keep good teachers (charters have a much higher turnover of teachers than other schools because the working conditions are poor and the pay is mediocre relative to other districts). Since the alleged measure of student performance is test scores, many teacher opt for an easy route of going to higher paying, wealthier districts where the kids are likely to do well on tests with letter effort on the teacher's part. So districts like Buffalo, Cheektowaga where the scores are consistently lower, it's harder to get teachers to work there. The same goes for charters.
Interesting that there's no call for charters in East Aurora, Clarence, etc., must be because the areas are a fairly homogeneous population to begin with.
