Rasch Measurement – Core Topics

Rasch Measurement – Core Topics

This course will teach you how Rasch analysis constructs linear measures from scored observations. You will learn the practical aspects of data setup, analysis, output interpretation, fit analysis, differential item functioning, dimensionality and reporting.

Overview

Rasch analysis constructs linear measures from scored observations, such as responses to multiple-choice questions, Likert scales and quality-of-life assessments. This course covers the practical aspects of data setup, analysis, interpretation and reporting. Simple test linking and equating designs are addressed, and supporting theory is presented conceptually. The course will use a time-limited version of Winsteps software, and Microsoft Excel is used extensively.

  • Install Winsteps software
  • Describe basic test and Rasch measurement concepts
  • Conduct simple dichotomous analysis
  • Describe and fit the Rasch-Andrich rating scale model
  • Account for partial credit
  • Develop designs simple test linking and equating

Who Should Take This Course

Survey researchers, social scientists who use surveys or questionnaires in their work, education assessment analysts and managers.

Dr. Everett V. Smith, Jr

Everett V. Smith Jr. obtained his Ph.D. in Educational Psychology with a specialization inMeasurement and Evaluation from the University of Connecticut in 1995. He specializes inpsychometrics, specifically Rasch measurement. His research interests and expertise includetest and rating scale design and analysis for the measurement of latent constructs, testing modelrobustness, and, in general, applications of Rasch measurement in the social, behavioral, health,rehabilitation, and medical sciences for both criterion and norm-referenced assessments. Amongthese applications include studies of dimensionality, DIF, cross-cultural equivalence, equating,item banking, rating scale optimization, and standard setting.
