When I first walked into John Marshall High School in 1992, I was stunned by the exceptional quality of so many teachers.It had never occurred to me that such great teaching and learning was being done in high schools. Yes, there were problems, but each year, our school would make incremental improvements.Then, the Oklahoma City Public Schools system (OKCPS) would bow to pressure and implement disastrous policies that would wipe out those gains — or worse.I remember when OKCPS was first forced into policies that were later dubbed “corporate school reform.”The No Child Left Behind Act, which was signed into law in 2002 by former Republican President George W. Bush, increased the federal government’s influence in holding schools accountable for student performance.During the first years after the passage, local and state leaders often had some success in minimizing the damage done by school “choice” and high stakes testing. But, as in the rest of the nation, that resistance angered marketdriven reformers who then doubled- down on harsher, more punitive policies.They ordered everyone to “be on the same page,” and even today press educators to “teach to the test.”I quickly discovered that this one-size-fits-all philosophy was disastrous for schools, teachers and students. And decades later, it still remains so.It doesn’t take into account the difference between situational and generational poverty. It ignores that some students are seriously emotionally disturbed and/or burdened by multiple traumatic experiences, now known as Adverse Childhood Experiences (ACEs). And, it fails to factor in that children, who may have reading or math disabilities, have the potential to become student leaders.The tipping point for me was when school staffing became driven by a primitive statistical model that could not distinguish between low income students and children of situational poverty receiving free and reduced price lunches as opposed to children living in extreme poverty with multiple ACEs.Because of the additional costs of providing services for the most emotionally disturbed students, teachers in “regular” classrooms were assigned up to 250 students.I had classes with 60 students. Data-driven accountability pollutes our learning cultures.School segregation by choice combined with test-driven accountability creates a culture of competition, winners and losers, and simplistic policies that ignore poverty and Adverse Childhood Experiences.It is a policy imposed mostly by non-educators who ignore educational and cognitive scientific research.As these quick fixes failed — just like educators and social scientists predicted they would — the “blame game” took ...
