| Read a Post for When Statistical Significance Hides More Than it Reveals | | | | Reply to this Post | | | How Many Clarifications Does it Take to Clarify What Doesn't Work? | | Posted By: Dick Schutz on July 8, 2014 | | | Let's see if I've got this straight. First, we have the study reports. That's Clarification 1.
Then we have the CREDO reports to clarify the studies. That's 2.
Then we have the WWC reports to clarify the CREDO analyses. That's 3.
Then we have the present note to clarify the WWC reports. That's 4.
The 4th-order clarification: "the average effect of charter schools on students’ achievement gains is negligible." Moreover,"the considerable variation in achievement gains within and across subgroups of students and schools"--the variability the research should be untangling--is ignored.
Meanwhile, the Federal Government is badgering and bribing "practitioners" to establish more charter schools.
While the 4th-order clarification finally tells it like it is, it seems to me that "bridging the gulf between research and practice" entails both more and less than focusing on the "summaries generated from research studies."
