Selected Research Project
Project Title Developing a Framework of Item Response Models for Multifaceted Data
Principal Investigator

Professor Wang Wen Chung

Area of Research Project
Educational Measurement and Assessment
Project Period
From 1/2012 To 12/2013
  1. To critique existing IRT models for multifaceted data;
  2. To develop a new framework for integrating existing models and creating new models;
  3. To develop parameter estimation procedures for the new framework;
  4. To conduct a series of simulation to assess effectiveness of parameter recovery and statistics for model comparison and model data fit; and
  5. To demonstrate implications and applications of the new framework with empirical examples.
Methods Used
  • Development of the new model for multifaceted data;
  • Development of parameter estimation procedures and computer programs;
  • Simulation studies; and
  • Real data analyses.
Expected Findings

A general framework of model for multifaceted data will be established to allow many existing item response theory models to be included in the framework. Computer programs for existing and new models will be introduced to the audience with a series of implementations and applications.

Expected Impacts
  • The general framework will be more effectively account for multifaceted data and in revealing valuable information.
  • Guidelines, computer programs, and annotated examples will be provided to promote the new framework.
