ConstructMap
ConstructMap is software designed for conducting simple psychometric analyses on categorical data. It has been developed as a companion to Constructing Measures (Wilson, 2005), an introductory book on assessment in the social sciences.
ConstructMap can run analyses on dichotomous data using the Rasch Model or on polytomous data using the Partial Credit Model or the Rating Scale Model. In addition to the model results, ConstructMap can produce several plots, such as Wright Maps, Item Fit Plots and Item Characteristic Curves, to help in the interpretation of those results.
About
ConstructMap is a graphical, menu-driven software package that combines a multidimensional IRT engine for estimating item and person parameters with tools for managing cross-sectional and longitudinal student response data and interpreting findings from such data. Graphical maps and reports are designed for use in settings in which progress on multiple measures can be examined and analyzed. Users can select expected a posteriori (EAP), maximum likelihood, or plausible value estimates of multivariate proficiency estimates. ConstructMap accepts dichotomous, rating scale, or partial credit items in between-item (each response is an indicator of a single dimension) or within-item (a response may be an indicator of multiple dimensions) multidimensional models.
