Dear Rasch Colleagues,
(pls forgive cross-postings)
A number of colleagues have asked whether the changes to the second
edition of Bond & Fox "Applying the Rasch Model" are worth the price.
Let me try to give a (sort-of) objective summary answer.
What's new in 2nd Edition
2nd Ed. = 314 pages + (refs and front material);
1st Ed.= 234 pages + (refs and front material).
Updated throughout, highlights of the Second Edition include:
Additional 80 pages of text; More than 25% of the rest rewritten.
A new CD that features Bond&FoxSteps, a full-size introductory
version of the latest Winsteps program; all the data files for the
book's examples, preprogrammed to run using Winsteps with built-in
.pdfs of step by step tutorials for each B&F example. Minifac, data
set and Facets example.
A new chapter (#5) on invariance that highlights the parallels
between physical and human science measurement.
A new empirical example demonstrates the Many Facets Rasch model.
An increased focus on issues related to unidimensionality,
multidimensionality, and Rasch factor analysis of residuals.
New examples using thermometry and the measurement of sport
performances, and the growing use of student satisfaction data in
university and college reviews.
A new appendix on analyzing data to help those new to Rasch analysis
More explanation of the key concepts and of item characteristic
curves make the text easier to follow.
You might not know that Taylor & Francis now own Erlbaum, and they
have made this offer to Rasch-list members etc.
The T&F website administrator has programmed a "discount code" for
buyers to add in when ordering the book via the Psychology Press
The discount code is "PPIOM" - people on Rasch listserves can order
it off (any one of) the T&F websites.
At the checkout stage you'll be given the opportunity to enter a
promotional code - enter PPIOM in that field and click "Apply
This url will send you to the book's page on the web site:
This discount is 20% off and is good for 90 days.
Nothing else to say otherwise subjectivity and defence mechanisms
might take over!
