Content
This unit begins with an introduction to the historical development of test theory and how modern test theory has superseded traditional test theory in many applications, especially in large-scale assessments.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.
Outcomes
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.
Assessment
Typically this unit is assessed in the following ways: (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.

Note
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.
Texts

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.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
