item response theory

This post finds me writing from Arnhem, The Netherlands, home of Cito and host to the IACAT 2010 conference.  I’m looking forward to hearing some of the excellent CAT research that is happening around the world.  The conference has 130 participants from approximately 45 countries – and the organization is only one year old!

 

FastTEST Web (www.fasttestweb.com) has seen several important additions over the last month.  Perhaps the most unique is an API functionality, which allows other software systems to interface efficiently.  For example, if your organization has its own test delivery engine, but wishes to utilize FastTEST Web‘s powerful item banking, you can now easily make use of both.  The next addition is to increase the number of reports available, both on the item bank itself and on examinee data.

 

ASC has also continued to work on the new Iteman 4.  Version 4.1 will be released soon, which includes additional output (both graphical and statistical), as well as the capability to work with polytomously scored items (rating scale or partial credit).  This version will even be able to work with mixed-format tests, such as a test composed primarily of multiple-choice items with a few open-response items at the end.  It is a free upgrade from version 4.0, so make sure to update your copy.

 

We will also soon be releasing two more updates.  ScoreAll 2.0 provides an additional level of detail in scoring conventional tests as well as updated interface.  POSTSIM 3.0 cements its spot as the foremost software for computerized adaptive testing (CAT) research by now providing hybrid simulations, a new methodology developed by David Weiss.  This methodology is especially useful because it is designed for sparse matrices, which typically occurs in CAT pilot testing.

Nathan Thompson earned his PhD in Psychometrics from the University of Minnesota, with a focus on computerized adaptive testing. His undergraduate degree was from Luther College with a triple major of Mathematics, Psychology, and Latin. He is primarily interested in the use of AI and software automation to augment and replace the work done by psychometricians, which has provided extensive experience in software design and programming. Dr. Thompson has published over 100 journal articles and conference presentations, but his favorite remains https://pareonline.net/getvn.asp?v=16&n=1.
