School aged children: Visual perception and reversal recognition of letters and numbers separately and in context
… Model of Rasch Measurement was used to order the items on a scale from easy to difficult and the student measures were calibrated on the same scale from low to high. In each scale, items were scored zero (for incorrect) and one (for correct). The student sample N=324 used in this study included …

THE EFFECTS OF READER CHARACTERISTICS, TEXT FEATURES, AND COMPREHENSION PROCESSES ON READING COMPREHENSION
… understood, psychometric theory dictates that item difficulty can be explained through these processes. The goal of the project was to improve understanding of reading comprehension and the role of reader characteristics, passage features, and comprehension processes in understanding text …

Testing the Assumption of Sample Invariance of Item Difficulty Parameters in the Rasch Rating Scale Model
… model, it is mathematically proven that the item difficulty estimates are independent of the sample of respondents. The purpose of this study was to test the robustness of the Rasch model with regards to its ability to maintain invariant item difficulty estimates when real (data that does not …

Student English achievement, attitude and behaviour in bilingual and monolingual schools in Aceh, Indonesia
… the three variables was tested by designing the items in ordered patterns of item difficulty which were compared with their Rasch-measured item difficulties, as a Science-like test of the structure of the variables. An experimental research design (pretest/posttest, control/experimental group) …

A Rasch Analysis of the Mental Health and Recovery Measure: Reliability and Validity
… Health Recovery Measure (MHRM). The MHRM is a 30-item scale developed based on a grounded theory analysis (Young & Ensing, 1999) of information from individuals with severe and persistent mental illness regarding their understanding of the “lived experience” of recovery. The MHRM has previously …

Interstellar Gas Clouds and Gen. Ed. Astronomy Students: Who Are They? How Do They Behave?
… a framework of results that is used to evaluate item difficulties, item discriminations, and the overall reliability of the LSCI. We perform an analysis of individual student’s normalized gains, providing further insight into the prior results from this data set. This investigation allows us to …

Assessing Robustness of the Rasch Mixture Model to Detect Differential Item Functioning - A Monte Carlo Simulation Study
… to true latent ability differences. Differential item functioning (DIF) occurs when measurement invariance is violated. There are two kinds of traditional tools for DIF detection: non-parametric methods and parametric methods. Mantel Haenszel (MH), SIBTEST, and standardization are examples of …
