[I]t evaluated student progress on math tests in half the nation’s five thousand charter schools and concluded that 17 percent were superior to a matched traditional public school; 37 percent were worse than the public school; and the remaining 46 percent had academic gains no different from that of a similar public school.So, on the whole charter schools are worse than public schools on this measure.
may "meet and confer" or consult annually with school boards and administrators over salaries, benefits, and working conditions. But the teachers' requests are non-binding, and points of impasse between teachers and administrators are usually resolved without the benefit of outside mediation or arbitration.Texas teachers may not generally utilize collective bargaining tools such as strikes or walkouts.
[Eric] Hanushek [of the Hoover Institution] has released studies showing that teacher quality accounts for about 7.5–10 percent of student test score gains. Several other high-quality analyses echo this finding, and while estimates vary a bit, there is a relative consensus: teachers statistically account for around 10–20 percent of achievement outcomes. Teachers are the most important factor within schools.posted by russilwvong at 11:02 AM on October 22, 2010 [2 favorites]
But the same body of research shows that nonschool factors matter even more than teachers. According to University of Washington economist Dan Goldhaber, about 60 percent of achievement is explained by nonschool factors, such as family income. So while teachers are the most important factor within schools, their effects pale in comparison with those of students’ backgrounds, families, and other factors beyond the control of schools and teachers. Teachers can have a profound effect on students, but it would be foolish to believe that teachers alone can undo the damage caused by poverty and its associated burdens.
