Given the important role that teachers play in supporting student mental health, it is critical teachers feel confident in their ability to fill such roles. To inform strategies intended to improve teacher confidence in supporting student mental health, a psychometrically sound tool assessing teacher school mental health self-efficacy is needed.…

Retief, Liezel; Potgieter, Marietjie; Lutz, Marietjie – African Journal of Research in Mathematics, Science and Technology Education, 2013
In this paper the use of the Rasch model is explored as a transparent, systematic and theoretically underpinned response to quality issues that are widely recognised as problematic in the refinement of Likert scale questionnaires. Key issues are the choice of length of scale, the pursuit of a favourable estimate of Cronbach's alpha at the possible…

Tong, Ye; Kolen, Michael J. – Educational Measurement: Issues and Practice, 2010
"Scaling" is the process of constructing a score scale that associates numbers or other ordered indicators with the performance of examinees. Scaling typically is conducted to aid users in interpreting test results. This module describes different types of raw scores and scale scores, illustrates how to incorporate various sources of…

Using an anchor-item design of test equating, the effects of three equating methods (Tucker linear and two three-parameter item-response-theory-based (3PL-IRT) methods), and the content representativeness of anchor items on the accuracy of equating were examined; and an innovative way of evaluating equating accuracy appropriate for the particular…

Ackerman, Terry A. – 1992
The concept of a user-specified validity sector is discussed. The idea of the validity sector combines the work of M. D. Reckase (1986) and R. Shealy and W. Stout (1991). Reckase developed a methodology to represent an item in a multidimensional latent space as a vector. Item vectors are computed using multidimensional item response theory item…

Doig, Brian A. – 1992
How data gathered through item response theory (IRT) analysis can be used to give immediate diagnostic information without a computer is explained. The Kidmap, developed by B. D. Wright and others (1980), provides clear information in a visual manner. Its major problem lies in the need for a computer and suitable software to construct a Kidmap.…
