Practical Rasch Measurement - Core Topics

Practical Rasch Measurement - Core Topics

taught by Everett Smith

Aim of Course:

Rasch analysis constructs linear measures from scored observations, such as responses to multiple-choice questions, Likert scales and quality-of-life assessments. This online course, "Practical Rasch Measurement - Core Topics" covers the practical aspects of data setup, analysis, output interpretation, fit analysis, differential item functioning, dimensionality and reporting. Simple test linking and equating designs are addressed. Supporting theory is presented conceptually.

This course may be taken individually (one-off) or as part of a certificate program.
Course Program:

WEEK 1: Basic Concepts and Operations

  • Winsteps software installation and operation
  • Basic measurement and Rasch concepts
  • Simple dichotomous analysis
  • Constructing data files

  • Partial Credit Model
  • Category Description
  • Standard errors and Reliability
  • Anchoring

DTF, DIF, and dimensionality

  • Differential Test Functioning
  • Differential Item Functioning

Homework in this course consists of short answer questions to test concepts and an end of course measurement construction project.

Practice tasks are also provided to allow participants the opportunity to practice the concepts being taught with provided data sets.

In addition to assigned readings, this course also has supplemental readings available online.

Options for Credit and Recognition:
Specializations are an easy way for you to demonstrate mastery of a specific skill in statistics and analytics. This course is part of the Rasch & Item Response Theory Specialization which gives a deep dive into statistical methods for calibration and equating of test instruments.  Take any three of the four courses on this topic (this course, plus the courses listed to the right under "related courses," not including conferences).  For savings, use the promo code "rasch-specialization" and register for all three courses at once for  $1197 ($399 per course, not combinable with other tuition savings).  If you register for all four, you'll still receive the discounted rate.
Course Text:
All necessary study material is provided online by the instructor.
The course will use a time-limited version of Winsteps software available when the course starts. Microsoft Excel is used extensively. NOTE: Winsteps does not run on native Macintosh OS; you will need to be running Windows.
