Recently this column famous that scholar journalists at Stanford University have been shining a lightweight on a well-paid schooling professor on the faculty who’s been serving to to water down California’s Okay-12 math requirements. Now one other professor at Stanford—one who’s truly within the math division— has examined the analysis used to justify the brand new Okay-12 requirements and finds severe flaws. Stanford math professor Brian Conrad reviews “many misrepresentations.”
The effort to vary Golden State math instruction had already encountered severe opposition. A Journal editorial in December famous a public assertion from tons of of the nation’s prime quantitative scientists warning in regards to the assault on math in faculties:
“We write to express our alarm over recent trends in K-12 mathematics education in the United States,” the assertion begins. The social-justice wave of 2020 accelerated efforts to eradicate standardized testing and decrease requirements in math to present the looks that achievement gaps don’t exist.
The scientists delicately describe the politicized erosion of requirements as “well-intentioned approaches to reform mathematics education.” They zero in on the California Department of Education’s proposed new math framework, which inspires math academics to take a “justice-oriented perspective.” The signatories say the course roadmap will scale back the “availability of advanced mathematical courses to middle schoolers and beginning high schoolers” and discourage college students from taking calculus.
This is meant to advance “equity.” But along with damaging America’s international competitiveness, the letter says, the decline of rigorous math in public faculties “may lead to a de facto privatization” of top-tier instruction and “harm students with fewer resources.”
Now Stanford’s Prof. Conrad, who directs undergraduate research within the math division, reviews on his deep dive into the brand new California Mathematics Framework for Okay-12 college students:
When I learn the brand new CMF posted in mid-March, I encountered a whole lot of assertions that have been onerous to imagine and have been justified through citations to different papers. So I learn these different papers. To my astonishment, in primarily all instances, the papers have been significantly misrepresented within the CMF. Some papers even had conclusions reverse to what was mentioned within the CMF… The CMF incorporates many misrepresentations of the literature on neuroscience, and statements betraying a lack of awareness of it.
…The CMF claims Ramani and Siegler (2008) confirmed that “after 4 15-minute periods of enjoying a sport with a quantity line, variations in information between college students from low-income backgrounds and people from middle-income backgrounds have been eradicated’’.
It could be nice if eliminating academic gaps have been as straightforward as enjoying a sport a number of instances. But Ramani and Siegler confirmed nothing of the kind. Their paper exhibits the non-surprising consequence that enjoying a sport on a quantity line improves preschoolers’ efficiency on a process of approximating the place of a quantity on the road. It doesn’t say something about variations in mathematical information.
(iii). In a number of instances the CMF argues towards acceleration by citing papers that both don’t justify the statements or come to the alternative conclusion…
(v). In some locations, the CMF has no research-based proof, as when it offers the recommendation “Do not embrace homework …. as any a part of grading. Homework is among the most inequitable practices of schooling.’’ The analysis on homework is complicated and blended, and doesn’t assist such blanket statements.
(vi). The CMF claims that Sadler and Sonnert (2018) supplies proof in favor of delaying calculus to varsity, however the paper finds that taking calculus in high-school improves efficiency in school.
(vii). The CMF makes the dramatic declare that (Black et al, 2002) (actually 2004) confirmed that college students “are extremely correct at assessing their very own understanding, and they don’t over or underneath estimate it.’’ If this declare have been true, no exams could be wanted to evaluate scholar information: we may simply ask them. Unfortunately, the paper of Black et al incorporates nothing of the kind.
The abundance of false or deceptive citations I discovered within the CMF calls into doubt the credibility of all citations to the literature within the CMF…
My grade for the CMF’s correct illustration of the cited literature is F.

Another Bloody Weekend in Chicago
Most elected Democrats have discovered to cease speaking about defunding the police, however this doesn’t imply the violence plaguing many American cities has returned to pre-2020 ranges.
NBC station WMAQ in Chicago reviews:
Chicago noticed one other lethal weekend, with at the least 9 individuals killed and 26 others wounded per week after greater than 40 individuals have been shot, seven of them fatally, within the metropolis.
Along with the tragic destruction of harmless lives, the violence can be threatening the livelihoods of people that rely on the town’s evening life. The Chicago Tribune editorializes:
On Sunday evening, joyful patrons have been seated on the James M. Nederlander Theatre in Chicago’s Loop ready for the beginning of a touring manufacturing of the Broadway musical “Moulin Rouge.” The theater, say some who have been there, was properly stuffed. But simply moments earlier than the scheduled curtain time, an announcement was comprised of the stage that the present had been canceled.
The purpose was a close-by taking pictures.
According to police, victims of a theft opened fireplace on the perpetrators. But they as a substitute hit two individuals whom the police referred to as “unintended targets,” which is code for being unlucky sufficient to be standing within the alley exterior the Chicago Theater. Both have been taken to hospitals in (fortunately) truthful situation. One of them was a health care provider, for goodness sake, and one among them, was a stagehand who labored on “Moulin Rouge.” That was sufficient to make many concerned within the manufacturing understandably unwilling or unable to carry out or crew the present. Thus the viewers was despatched residence…
Broadway in Chicago officers and staff have been saying for months that police safety within the theater district is insufficient and lots of viewers members advised reporters Sunday evening that that they had been reluctant to come back to the Loop within the first place.
