Everett V. Smith, Jr

Continues the exploration of Rasch theory and its application in the Winsteps software begun in Practical Rasch Measurement-Core Topics. The visual step-by-step tutorial propels you along the road to success. The course introduces exciting new topics and delves into earlier topics more deeply. Meaningful findings always require careful screening of data, and may require judicious data selection and editing. Even the most profound findings are ignored by decision-makers unless they are presented clearly, powerfully and briefly. In accord with these precepts, you are guided toward successfully analyzing data and communicating your findings.

HOMEWORK:

Homework in this course consists of short answer questions to test concepts.

This course takes place over the internet at the Institute for 4 weeks. During each course week, you participate at times of your own choosing - there are no set times when you must be online. Course participants will be given access to a private discussion board. In class discussions led by the instructor, you can post questions, seek clarification, and interact with your fellow students and the instructor.

The course typically requires 15 hours per week. At the beginning of each week, you receive the relevant material, in addition to answers to exercises from the previous session. During the week, you are expected to go over the course materials, work through exercises, and submit answers. Discussion among participants is encouraged. The instructor will provide answers and comments, and at the end of the week, you will receive individual feedback on your homework answers.

1. You may be interested only in learning the material presented, and not be concerned with grades or a record of completion.
2. You may be enrolled in PASS (Programs in Analytics and Statistical Studies) that requires demonstration of proficiency in the subject, in which case your work will be assessed for a grade.
3. You may require a "Record of Course Completion," along with professional development credit in the form of Continuing Education Units (CEU's).  For those successfully completing the course, 5.0 CEU's and a record of course completion will be issued by The Institute, upon request.

All necessary study material is provided online by the instructor. Helpful additional study material can be found in the book Introduction to Rasch Measurement (Smith & Smith, Eds., 2004, JAM Press). The text can be ordered directly from the publisher, JAM Press, by clicking here.

The course will use a time-limited version of Winsteps software available when the course starts. Microsoft Excel is used extensively.
