6 points
Not available in 2020OnlineOnline
This unit begins with an introduction to the historical development of test theory and how modern test theory has superseded traditional test theory in many applications, especially in large-scale assessments. In particular, students learn how Rasch measurement incorporates, elaborates and better achieves the goals of traditional test theory. The unit includes lectures on the formalisation and calculation of traditional reliability and reliability in Rasch models, the concept of validity in both traditional and modern test theory, the concepts of invariance and sufficiency in Rasch measurement, diagnosing the fit of responses to the Rasch model, and the Rasch model for dichotomous items and for items with ordered response categories.
Students are able to (1) explain the basic principles of Rasch measurement theory in the social sciences; (2) understand the principles of traditional test theory in terms of Rasch measurement theory; (3) use a range of diagnostic tools in order to assess the quality of items in constructing assessment instruments of achievement, knowledge and attitude; and (4) apply software in analysing assessment data.
Indicative assessments in this unit are as follows: (1) assignments and (2) a three-hour open book test. Further information is available in the unit outline.

Supplementary assessment is not available in this unit.

Students participate with unit coordinators and other students in an online discussion group. For the duration of the unit, students have the use of the RUMM2030 software, a very easy to use interactive program that analyses data according to the Rasch measurement model.

Enrolled students obtain: (1) a set of lecture materials which includes hard copies of all of the lectures; (2) details of the assignments; (3) the necessary reading materials; and (4) the Study Guide setting out the steps to successfully complete the unit.
