So very many myths to puncture....so little time.
Consider the following....
"That class size should be small is revered like an article of faith in this country. Its adherents include parents, education groups, politicians and, of course, the unions whose ranks it swells. In many states it is even required by law, which has lead to millions of dollars in fines against schools in Florida and a lawsuit against New York City by its teachers union."
The cost of small class size - The Washington Post
Smaller classes means more teachers hired, which, in turn, means more union dues which can be used to purchase more....politicians....who push for even smaller classes.
But, intuitive though it may be....there is no truth to the view that smaller classes result in more learning.
The opposite may be true.
1. "Last month, ... officials in the Brevard County Schools had broken Florida state law—on purpose. Their offense? Placing more kids in classrooms than Florida’s Class Size Reduction statute allows..... What if they had assigned the “extra” students to their most effective teachers, leaving fewer pupils in classrooms presided over by weaker instructors?
What would be the impact of such a practice on student achievement?
2. The idea is straightforward: Give the better teachers more kids and the weaker teachers fewer—then see what happens. It’s a common-sense option with many supporters. We know, for instance, that parents say they would opt for larger classes taught by excellent teachers, rather than smaller classes with instructors of unknown ability.
a. In a study last year for the Fordham Institute, the FDR Group found that a whopping 73 percent of parents would choose a class with twenty-seven students—provided it is “taught by one of the district’s best performing teachers”—over a class of twenty-two students “taught by a randomly chosen teacher.”
3. Further, given the choice between fewer students and more compensation, the teachers themselves choose the latter. In a well-done study of their own, Dan Goldhaber and colleagues found that 83 percent of educators in Washington State would prefer an additional $5,000 in compensation versus having two fewer students in their classes.
4. Given districtsÂ’ aversion to assigning students [equally to all teachers], ....we approached economist Michael Hansen, a senior researcher at the American Institutes for Research. Dr. Hansen, an expert in labor economics and the economics of education, has ample experience mining North Carolina data and conducting simulations of this genre.
a. He uses three years of data (2007–10) to generate past value-added measures. For the fourth year, he estimates how teachers actually performed, and then he simulates what the impact would have been if students instead had been allocated to teachers based on their prior performance, with an eye towards maximizing student gains. The allocation process results in larger classes for the most effective teachers and smaller for the least effective.
5. The key finding: Minor changes in assignment lead to improvements in student learning. The results were relatively modest for the fifth grade; there, even when as many as twelve additional pupils were assigned to effective teachers, it yielded gains equivalent to extending the school year by just two days.
6.. At the eighth-grade level, however, the results were much more robust. Hansen found that assigning up to twelve more students than average to effective eighth-grade teachers can produce gains equivalent to adding two-and-a-half extra weeks of school.
7. Yet adding fewer students pays dividends, too. In fact, 75 percent of the potential gain from allowing up to twelve students to be assigned to the best teachersÂ’ classes is already realized when allowing just six students to move. Specifically, adding up to six more than the schoolÂ’s average produces math and science gains akin to extending the school year by nearly two weeks. This impact is the equivalent of removing the lowest-performing 5 percent of teachers from the classroom.
8. And that is without actually removing them. As Hansen explains, “Class-size shifting enables the lowest-performing teachers to become more effective than they may be otherwise.”.... we should shrink some teachers’ classes down to zero students—and take the money saved thereby to bump up the compensation of effective teachers.
9.Last, Hansen examines whether this reallocation policy helps our neediest students gain more access to effective teachers. In a word, no. Gaps in access for economically disadvantaged students persist, primarily because the pool of available teachers in high-poverty schools remains unchanged under this strategy. Hence, this policy alone wonÂ’t remedy achievement gaps.
10. In the end, one simple change—giving effective teachers a handful more students—could mean a big boost to student achievement."
Right-Sizing the Classroom : Education Next
Liberals and Conservatives differ in the way to proceed. For Conservatives, data informs policy. (“More Guns, Less Crime” and “Mass murderers apparently can’t read, since they are constantly shooting up ‘gun-free zones.’”- Coulter)
We use Conservative principles to the best of our ability, but when confronting new and original venues, we believe in testing, and analysis of the results of the tests. For liberals, feeling passes for knowing; it is based on emotion often to the exclusion of thinking.
Here we can see the method applied to education.
Common sense alternatives supported by evidence......
Certainly worth a try.
