Study: Merit pay for teachers doesn't improve student test scores.
This article basically states the idea of "giving" a teacher more money based on if his/her students are performing well on standardized tests. This may give a teacher an incentive to try to teach kids more effectively, but the kids ultimately control the outcome. If a student does not want to do well in school or do any work, the outcome is likely not going to change. In the study, it revealed that the idea of giving teachers higher bonuses based on student performance will not change test scores and that does not surprise me.
It is also too narrow of a study because it does not show the work ethics of students or the influence their parents have and if it is a positive or negative one. "Teachers do their part to teach as best as they can, and students must do their part by reinforcing it," is a quote I have heard from another teacher.
