Rasch Measurement Theory: A Complete Course

"Rasch Measurement Theory: A Complete Course" is a comprehensive guide to understanding Rasch measurement theory. We offer an essential resource for anyone interested in measurement theory, educational assessment, or social science research. Rasch measurement theory, named after Danish mathematician Georg Rasch, provides a framework for developing valid and reliable measurement instruments. Unlike traditional psychometric approaches, Rasch measurement theory emphasizes the principles of measurement itself. At the heart of Rasch measurement theory is the Rasch model, which posits that the probability of a respondent endorsing an item on a scale depends on the relationship between the respondent's ability and the difficulty of the item. This model forms the basis for various measurement applications. We introduce the basic principles of Rasch measurement theory and provide step-by-step guidance on applying Rasch analysis to real-world data. Our book emphasizes practical applications with examples from education, psychology, and healthcare. We also explore advanced topics such as differential item functioning (DIF), multidimensional Rasch models, and item response theory (IRT). Throughout the book, we offer tips for conducting Rasch analysis using software packages like RUMM, Winsteps, and jMetrik.
