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? Assignment and student-work measures were developed with Many-Facet Rasch analysis to adjust ratings for scorer severity, standard difficulty, and step difficulties between score categories. → Wenzel 2002

In the measure-development stage, the project used the Many-Facet Rasch model, noting that besides adjusting for rater severity and standard difficulty, "another advantage of the Rasch model is that it allows for missing data." Final assignment measures exist in a logit metric with standard errors, converted to a 0-10 scale for reporting.
"the student work and teacher assignment measures were developed using Many-Facet Rasch Analysis with statistical software specifically designed for this model, FACETS."
Discussion¶
Related Claims¶
- Raters differed significantly in severity/leniency in the MFRM analysis — related
- CTT and MFRM yield similar item difficulty results for open-ended questions regardless of crossed or nested design — related
- CTT and MFRM yield a positive, perfect correlation between item difficulty indices for open-ended items under a crossed design — related
- Items ranked from easiest to most difficult are identical under CTT and MFRM — related
- Scorers found all rubric dimensions important, with feedback bearing mainly on the scoring and training process rather than rubric design — related
- Scorers had difficulty distinguishing rubric scoring from everyday grading and AP scoring, and training took longer than expected — related
