Certain criticisms of the use of the Rasch model have been queried in a paper by Bryce. We argue that these criticisms not only remain valid, but are reinforced by recent research on latent trait models. In particular, Bryce fails to present a clear conceptual argument and adopts a very inefficient procedure for testing empirically the fit of the Rasch model. A paper by Bryce (1981) takes issue...

the role of teachers in the educational context could go beyond simply teaching the subject matter. it is not uncommon for some students to be greatly influenced by certain teachers and even consider them as their role models. an interesting and novel way of inferring the impact a teacher has on the students is through revealing the status of the teacher as perceived by the students. the presen...

background: quality of life evaluates the general well-being of individuals and it can be considered as one of the important aspects in programming and giving service to disabled people. blindness is one of the most important kinds of physical disability that has a direct effect on quality of life, so t his study aimed to explore how war blindness influences the quality of life .   methods: in ...

The purpose of this study is to apply the Rasch model to investigate both the Van Hiele theory for geometric development and an associated test. In terms of the test, the objective is to investigate the functioning of a classic 25-item instrument designed to identify levels of geometric proficiency. The data set consists of responses by 244 students (106 for a pre-test and 138 for a post-test) ...

Tacit knowledge was originally introduced into the professional literature by Michael Polanyi and later made popular by researchers in a variety of domains. Measuring this implicit form of procedural knowledge requires multiple approaches to adequately “capture” what is often known, but not easily articulated. The present study combines use of Sternberg et al.’s framework for capturing domain-s...

What does it mean to align an assessment to the domain of interest? In this paper, we analyze teachers’ performance on the Learning Mathematics for Teaching assessment of Proportional Reasoning. Using a mixture Rasch model, we analyze their performance on the entire assessment, then on two different subsets of items from the original assessment. We consider the affordances of different conceptu...

We examine the Rasch model for latent structure para‎- ‎meters in ‎binary and multiple response questionnaires and develop‎ ‎methodologies and data-analytic tools for assessing‎ ‎collaboration/che‎- ‎ating in multiple choice tests

Does the reader comprehend the text because the reader is able or because the text is easy? Localizing the cause of comprehension in either the reader or the text is fraught with contradictions. A proposed solution uses a Rasch equation to models comprehension as the difference between a reader measure and text measure. Computing such a difference requires that reader and text are measured on a...

The purpose of this study is to examine the psychometric quality of the Teachers’ Sense of Efficacy Scale (TSES) with data collected from 554 teachers in a U.S. Midwestern state. The many-facet Rasch model was used to examine several potential contextual influences (years of teaching experience, school context, and levels of emotional exhaustion) on item functioning within the TSES. Results sug...
