Rise And Shine: A Comparison Of Item Fit Statistics For The Rasch Model, Glenn T. Waterbury
Rise And Shine: A Comparison Of Item Fit Statistics For The Rasch Model, Glenn T. Waterbury
Dissertations, 2020-current
The Rasch model implies that the relation between examinee ability and the probability of correctly answering an item can be defined solely by a small set of parameters. In the case of Rasch modeling, there are only two parameters: the ability of an examinee and the difficulty of an item. When the data meet the requirements of the Rasch model, it possesses several appealing properties that distinguish it from Classical Test Theory and more complex Item Response Theory models.
However, the desirable properties of the Rasch model only exist when the data meet its strict requirements. Therefore, it is vital …
Retrospective Versus Prospective Measurement Of Examinee Motivation In Low-Stakes Testing Contexts: A Moderated Mediation Model, Aaron J. Myers
Retrospective Versus Prospective Measurement Of Examinee Motivation In Low-Stakes Testing Contexts: A Moderated Mediation Model, Aaron J. Myers
Masters Theses, 2010-2019
Expectancy-value theory applied to examinee motivation suggests examinees’ perceived value of a test indirectly affects test performance via examinee effort. This empirically supported indirect effect, however, is often modeled using importance and effort scores measured after test completion, which does not align with their theoretically specified temporal order. Retrospectively measured importance and effort scores may be influenced by examinees’ test performance, impacting the estimate of the indirect effect. To investigate the effect of timing of measurement, first-year college students were randomly assigned to one of three conditions where (1) importance and effort were measured retrospectively; (2) importance was measured prospectively; …
