Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The percent of students at or above national norms in math fell from 46.4 percent in 2000 to 43.6 percent in 2001, and an equated Rasch score analysis replicated the GE decline for all cohorts except fourteen-year-olds. → Todd Rosenkranz 2002
Evidence¶
Todd Rosenkranz 2002¶
Todd Rosenkranz. (2002). 2001 CPS Test Trend Review: Iowa Tests of Basic Skills. Consortium on Chicago School Research. https://consortium.uchicago.edu/publications/2001-cps-trend-review-iowa-tests-basic-skills
q2 · i? · associational · r2
Supplementary re-analysis of 2001 CPS math scores using an equated Rasch score (logit), reported in the Decline in 2001 Math Scores sidebar. The same analysis notes the percent at or above norms fell from 46.4 percent in 2000 to 43.6 percent in 2001.
"The results of the Rasch analysis were the same as the GE trends in 2001 with one exception—the scores for fourteen-year-olds did not drop in Rasch. This suggests that the drop in the GE trends reflects an actual drop in learning and is not the product of the test form progression."
Discussion¶
Related Claims¶
- A Rasch-score re-analysis corroborates slowing and in some cases declining test score trends, with nine-year-olds an exception — a broader claim this one bears on
- Reading score trends flattened for ages 9-12 and declined at ages 9 and 12 in the grade equivalent metric by 2000 — related
- CPS elementary ITBS scores improved across the 1990s in both reading and math for all age groups, but trend gains flattened after 1998 — related
- Chicago elementary student achievement improved steadily from 1990 to 1999 under local control, with the share of students reaching national norms growing to 35 percent in reading and 43 percent in math — related
- For cohorts born since 1990, reading progress increased while math progress slowed — related
- CPS elementary school productivity improvements stalled after 1997, with no evidence of significant productivity growth since then — a broader claim this one bears on
