Stanford study lauds charter schools in New Orleans

Stanford University's Center for Research on Education Outcomes praised New Orleans charter schools in a study release last week. CREDO said in a press release it:


found that the typical student in a Louisiana charter school gains more learning in a year than his or her district school peer, amounting to about fifty more days of learning in reading and sixty-five more days of learning in math.

In addition to analyzing state trends, the study included a separate analysis of New Orleans charter schools. The study period included six years of schooling, beginning with the 2005-06 school year and concluding in 2010-11. During this study period nearly 80 percent of the public school students in the city attend charter schools, constituting 69 percent of the state’s charter school population. The results for the typical student in a New Orleans charter were even more pronounced than the state results, equating to more than four months of additional learning in reading and five months greater progress in math. At the school level, 50 percent of New Orleans charter schools have significantly more positive learning gains than their district school peers in reading and 56 percent in math.


Some tidbits from the study:

*"On average, students in Louisiana charter schools learned significantly more than their virtual counterparts in reading and mathematics. The results for the charter students in New Orleans show that they are growing even more by comparison to their TPS counterparts." (p.14)

*Remember stats in college? "The data is analyzed in units of standard deviations of growth so that the results will be statistically correct. Unfortunately, these units do not have much meaning for the average reader. Transforming the results into more accessible units is challenging and can be done only imprecisely. Therefore, Table 3 below, which presents a translation of various outcomes, should be interpreted cautiously" (p.15)

*"on average, charter students in Louisiana gain an additional 50 days, nearly three months of learning in reading over their TPS counterparts.9 In math, the advantage for charter students is about 65 days, more than three months of additional learning in one school year. Charter students in New Orleans gain an additional 86 days of learning in reading and 101 days in math over and above their state counterparts."

*"On average, Black students in charter schools have significantly better learning gains in reading and math compared to Black students in traditional public schools. Black charter students have 43 more days of learning in reading and 65 additional days of learning in math than their TPS counterparts." (p.23)

*"Charter students in poverty receive no significant benefit or loss in reading or math gains compared to their TPS peers in poverty." (p.25) However, that is due to the white students in poverty because the black students....

*"Black students in poverty who are enrolled in charter schools show significantly better performance in reading and math compared to Black students in poverty in TPS. Black charter students in poverty gain an additional 50 days of learning in reading and 65 more days in math than their peers in TPS." (p.26)

this study confirms that students who want to learn and are in a culture of learning will. Charter schools can, and do, boot the bad apples back to traditional public schools. if public schools could kick out students, they would "test" far better. since that will never happen, its just obvious that charter schools in failing school districts is the answer to save those who want to be saved!

BS. 86% of the NOLA kids are in charter schools. I think that probably covers more than a few of the bad apples.

Unless you are saying the 14% are all bad apples.

Go get another talking point.

The study begins in 2005. Katrina came through New Orleans in 2005 resulting in many demographic changes that might also result in drastically improved test scores.

The study shows statistical significance, but at .14 or less there is no practical significance. And without explaining how the study determined the number of days of learning in relation to standard deviations one cannot refer to that reliably. Basically, some charters do better, some do worse, some about the same as traditional public schools. As a side note, when CREDO 2009 came out charter supporters railed against it because it showed no significant gains. Now that CREDO 2013 shows significant (although impractical) gains, supporters now trumpet the study. Since CREDO 2013 states that poor performing charters have closed, and hinted that this attributed to some of the gains, the question begs: where did those students go? Into another charter? Back to traditional public schools?

Trollfest '09

Trollfest '07 was such a success that Jackson Jambalaya will once again host Trollfest '09. Catch this great event which will leave NE Jackson & Fondren in flames. Othor Cain and his band, The Black Power Structure headline the night while Sonjay Poontang returns for an encore performance. Former Frank Melton bodyguard Marcus Wright makes his premier appearance at Trollfest singing "I'm a Sweet Transvestite" from "The Rocky Horror Picture Show." Kamikaze will sing his new hit, “How I sold out to da Man.” Robbie Bell again performs: “Mamas, don't let your babies grow up to be Bells” and “Any friend of Ed Peters is a friend of mine”. After the show, Ms. Bell will autograph copies of her mug shot photos. In a salute to “Dancing with the Stars”, Ms. Bell and Hinds County District Attorney Robert Smith will dance the Wango Tango.

Wrestling returns, except this time it will be a Battle Royal with Othor Cain, Ben Allen, Kim Wade, Haley Fisackerly, Alan Lange, and “Big Cat” Donna Ladd all in the ring at the same time. The Battle Royal will be in a steel cage, no time limit, no referee, and the losers must leave town. Marshand Crisler will be the honorary referee (as it gives him a title without actually having to do anything).


Meet KIM Waaaaaade at the Entergy Tent. For five pesos, Kim will sell you a chance to win a deed to a crack house on Ridgeway Street stuffed in the Howard Industries pinata. Don't worry if the pinata is beaten to shreds, as Mr. Wade has Jose, Emmanuel, and Carlos, all illegal immigrants, available as replacements for the it. Upon leaving the Entergy tent, fig leaves will be available in case Entergy literally takes everything you have as part of its Trollfest ticket price adjustment charge.

Donna Ladd of The Jackson Free Press will give several classes on learning how to write. Smearing, writing without factchecking, and reporting only one side of a story will be covered. A donation to pay their taxes will be accepted and she will be signing copies of their former federal tax liens. Ms. Ladd will give a dramatic reading of her two award-winning essays (They received The Jackson Free Press "Best Of" awards.) "Why everything is always about me" and "Why I cover murders better than anyone else in Jackson".

In the spirit of helping those who are less fortunate, Trollfest '09 adopts a cause for which a portion of the proceeds and donations will be donated: Keeping Frank Melton in his home. The “Keep Frank Melton From Being Homeless” booth will sell chances for five dollars to pin the tail on the jackass. John Reeves has graciously volunteered to be the jackass for this honorable excursion into saving Frank's ass. What's an ass between two friends after all? If Mr. Reeves is unable to um, perform, Speaker Billy McCoy has also volunteered as when the word “jackass” was mentioned he immediately ran as fast as he could to sign up.


In order to help clean up the legal profession, Adam Kilgore of the Mississippi Bar will be giving away free, round-trip plane tickets to the North Pole where they keep their bar complaint forms (which are NOT available online). If you don't want to go to the North Pole, you can enjoy Brant Brantley's (of the Mississippi Commission on Judicial Performance) free guided tours of the quicksand field over by High Street where all complaints against judges disappear. If for some reason you are unable to control yourself, never fear; Judge Houston Patton will operate his jail where no lawyers are needed or allowed as you just sit there for minutes... hours.... months...years until he decides he is tired of you sitting in his jail. Do not think Judge Patton is a bad judge however as he plans to serve free Mad Dog 20/20 to all inmates.

Trollfest '09 is a pet-friendly event as well. Feel free to bring your dog with you and do not worry if your pet gets hungry, as employees of the Jackson Zoo will be on hand to provide some of their animals as food when it gets to be feeding time for your little loved one.

Relax at the Fox News Tent. Since there are only three blonde reporters in Jackson (being blonde is a requirement for working at Fox News), Megan and Kathryn from WAPT and Wendy from WLBT will be on loan to Fox. To gain admittance to the VIP section, bring either your Republican Party ID card or a Rebel Flag. Bringing both and a torn-up Obama yard sign will entitle you to free drinks served by Megan, Wendy, and Kathryn. Get your tickets now. Since this is an event for trolls, no ID is required. Just bring the hate. Bring the family, Trollfest '09 is for EVERYONE!!!

This is definitely a Beaver production.
