Mondrian is state-of-the-art statistical data visualization software featuring modern interactive visualization techniques for a wide range of data types. This article reviews the capabilities, functionality, and interactive properties of this software package. Key features of Mondrian are illustrated with data from the Programme for International…

This study investigated the usefulness of the many-facet Rasch model (MFRM) in evaluating the quality of performance related to PowerPoint presentations in higher education. The Rasch Model utilizes item response theory stating that the probability of a correct response to a test item/task depends largely on a single parameter, the ability of the…

This paper reviews the role of the item in test construction, and suggests some new methods of item analysis. A look at dynamic, graphical item analysis is provided that uses the advantages of modern, high-speed, highly interactive computing. Several illustrations are provided. (Author/TJH)

The IRT (Item Response Theory) has been studied and applied in computer-based test for decades. However, almost of all these existing studies evaluated focus merely on test questions with text-based (or static text/graphic) type of presentation form illustrated exclusively. In this paper, we present our study on test questions using both…

The Test Analysis Package (TAP) consists of three microcomputer programs that edit, score, summarize, and analyze student test data. Features of the TAP system include: (1) an editor that allows creation of a student test data file without the use of a separate word processor; (2) a scoring mechanism that can score a test data file of 999 students…

Computer programs are presented to plot item and test characteristic curves and item information functions for parameter estimates produced by the LOGIST and BICAL computer programs. These programs provide data in tabular format, but their usefulness in test development and measurement courses can be greatly enhanced by graphic plots of the item…

Effectiveness in presenting information of a modified box plot and a multivariate STAR graph was compared with that of tables for a sample audience for evaluation results (133 school superintendents, 123 journalists, 100 school board members, 100 principals, 100 teachers). Individual item analysis offers guidance for designing multivariate…
