Computerized Multistage Adaptive Testing: Theory and Applications

Duanli Yan, Alina von Davier, and Kyung Han

This course is intended for people who have some basic understanding of item response theory and CAT.

The focus of the workshop will be on MST theory and applications including alternative scoring and estimation methods, classification tests, routing and scoring, linking, test security, as well as a live demonstration of MST software MSTGen (Han, 2013). This workshop is based on the edited volume of Yan, von Davier, & Lewis (2014). The volume is structured to take the reader through all the operational aspects of the test, from the design to the post-administration analyzes. In particular, the chapters of Yan, Lewis, and von Davier; Lewis and Smith; Lee, Lewis, and von Davier; Haberman and von Davier; and Han and Kosinski are the basis for this workshop.

MSTGen (Han, 2013), a computer software tool for MST simulation studies, will be introduced by Han. MSTGen supports both conventional MST by routing mode and the new MST by shaping mode, and examples of both MST modes will be covered. The software is offered at no cost, and participants are encouraged to bring their own computers for a brief hands-on training.

There are four lecture sessions with hands-on examples using MST Gen software. This gives about 4 hours in total. The training course consists of a series of lectures and hands-on examples in the following four sessions:

1. MST Overview, Design, and Assembly

2. MST Routing, Scoring, and Estimations

3. MST Applications

4. MST Simulation Software.
