- PUP 5.20
retains the three-button (Import, Parse, and Score) simplicity, but now
has a section of advanced features:
Copy Detection can be turned off for large data sets.
A new Test
Characteristic Curve button produces a non-iterative
PROX algorithm IRT student ability-item difficulty table and tally chart.
- My blog, Multlple-Choice Reborn, is
carrying a six-week series on the Common Core State Standards movement
assessments starting, 24 Oct 2012, with Nebraska (one of the four states
not participating in the Common Core State Standards movement). The
Nebraska reading assessments compare
favorably with a number of nationally administered tests including the
ACT. Nebraska is one step away from having a fully balanced accurate, honest,
and fair state student performance assessment.
PUP 5.20 is now available free to 100 Nebraska
schools to use to promote student development and to prepare for accurate,
honest and fair Nebraska State Assessments. Please send requests to NeSAdevelopment@nine-patch.com.
- My blog, Rasch Model Audit, is now
finished after 47 posts over two years. Rethinking what the Rasch Model is
and how it has been used has been a fascinating exercise. The partial credit Rasch model,
developed in 1982 by Geoff Masters from Melbourne, and my Knowledge and Judgment Scoring
routine, created in 1981 at Northwest Missouri State University, produce
the same test scores but express quantity and quality scores differently.
5.20 can now color the unexpectedness of student marks on five printouts based
on Winsteps, Table
6 data, as a byproduct of the audit.
- Your comments and student mark data are still
needed and appreciated. Please reply if you want a free update of PUP to
