This course provides graduate students with an introduction to techniques for constructing and evaluating measurement instructions in the human sciences. Major topics include the latent trait models proposed by George Rasch and extensions of these models (dichotomous, polytomous, many-facet), the philosophy for measurement that corresponds to these models, software applications for conducting analysis with Rasch models, the interpretation and use of results from Rasch model analysis, and opportunities to evaluate real-world applications of Rasch models.
