Introduction to Rasch Measurement and Traditional Classical Test Theory (CTT): Course

External Study/online Unit from Murdoch University: July 23 ­ November 9, 2001

A graduate unit of study introducing Rasch measurement is offered in the external study mode, which can be studied from anywhere in the world. There will be a discussion group set up for online interaction. Students enrolled obtain (i) a set of lecture materials, (ii) the assignments, (iii) the necessary reading materials, and (iv) the Study Guide setting out the steps in the study. This unit was offered in the same period, 1999, and some 20 people from many parts of the world took the opportunity to enrol.

Features of the Unit:
1. It begins from first principles.
2. Exercises at the end of each lecture consolidate the ideas.
3. It introduces the Guttman structure as a lead into traditional test theory and Rasch measurement.
4. It covers elementary traditional test theory in a way that leads into the Rasch models.
5. It reviews the necessary elementary statistics to be able to understand the unit.
6. It studies the dichotomous model and introduces the Rasch model for ordered response categories.
7. It studies fit, including differential item functioning
8. A student version of the interactive Windows program RUMM for analyzing data is provided.
9. The discussion group permits you to interact with other students in the class.

Topics Covered in Lectures
1. Review of measurement and statistics in education and social science
2. Reliability and validity
3. Formalization of traditional reliability
4. Calculation of reliability
5. The Rasch model for dichotomous responses: The simplest latent trait model
6. Separation of person and item parameters
7. The significance of total scores
8. Estimating person ability and item difficulty
9. Fit of the responses to the model including Differential Item Functioning.
10. The Rasch model for ordered response categories: Analysis of partial credit or rated items
11. (a) A relationship between the reliability of traditional test theory and Rasch latent trait theory
11. (b) Linking using the Rasch model


Who should Enrol:

The unit is suitable for people from many social research backgrounds, but four in particular:

1. Professionals engaged in assessment and measurement of performance and attitude who know traditional test theory and are interested in learning the principles of modern test theory and Rasch measurement in particular.

2. People in education, social and health sciences who are concerned with outcome measurement.

3. People who have become familiar with Rasch measurement and item response theory through professional exposure, but would like to consolidate their understanding of its first principles.

4. Students who are involved in higher degree studies and require knowledge and evidence of studying educational and psychological measurement, in particular introduction to traditional and modern test theory.

Methods of Enrolling:

1. As a professional taking the unit as a professional development course. The only difference between this enrolment and the next two kinds of enrolment is that in this one no formal assessment and grading is carried out, although work handed in is marked. Those who have participated effectively are given a certificate of participation. Cost ca. $US650.00.

2. As a student from a university, other than Murdoch University. Students should check in advance if their university will give them credit for the unit.

3. As a student from Murdoch University.
