Subclaims¶

q2 i1 In the Gehring QED, there were three statistically significant positive mathematics impact estimates (effect sizes 0.24 to 0.34) and four statistically significant positive reading impact estimates (effect sizes 0.24 to 0.39); no science impact was significant. → Nakamoto 2022

q2 · i1 · causal · r2

Quasi-experimental design comparing Gehring magnet students in grades 1-5 with propensity-score-matched comparison students on winter 2020 MAP assessments. The report states "effect sizes ranging from 0.24 to 0.34" for mathematics and "0.24 to 0.39" for reading, all significant after Benjamini-Hochberg correction; science estimates were not significant.

"There were three statistically significant positive impact estimates for mathematics, with effect sizes ranging from 0.24 to 0.34. There were also four statistically significant positive impact estimates for reading, with effect sizes ranging from 0.24 to 0.39."

Related Claims¶

• The Kauffman School had positive, statistically significant impacts on student achievement growth in mathematics, reading, and science across 2011-2012 through 2013-2014 — related
• During its first seven years, the Kauffman School had substantial positive impacts on student achievement growth in mathematics, English language arts, and science beyond growth in other Kansas City public schools — related
• The Kauffman School produced substantial positive impacts on student achievement growth in mathematics, English language arts, and science over its first six years — related
• The Kauffman School's achievement impacts are higher than the average impacts found in studies of other charter schools — related
• Lied magnet students in grades 6-8 attempted and completed significantly more STEM credits than matched comparison students — related
• Students who attended FAST three or more times showed strong positive effects on Grade 1 reading and more modest effects on mathematics, but a strong negative effect on kindergarten attendance — related
• The evaluation has not yet rigorously examined whether the magnet schools reduce, eliminate, or prevent minority group isolation; this is deferred to the final report
• A lottery-based randomized controlled trial at Lied replicated the positive, statistically significant impact on 6th graders' mathematics achievement found by the QED — related
• Magnet schools across the studied cities show strong positive impact on students' performance growth compared to state averages — a broader claim this one bears on
