Investigating the processes underlying test performance is a major source of data supporting the explanation inference in the validity argument (Chappelle, 2021). One way of modeling the cognitive processes underlying test performance is by constructing a Q-matrix, which is essentially about summarizing the attributes explaining test-takers'…

In this study, the cloze-elide test was developed and administered under time constraints. This research is aimed to examine the validity and reliability of the speeded cloze-elide test and investigate its relationship with reading comprehension, C-Test, and multiple-choice cloze test. Processing speed is a vital indicator to distinguish high to…

Test method is deemed to affect test scores along with examinee ability (Bachman, 1996). In this research the role of method facet in reading comprehension tests is studied.

Standard unidimensional Rasch models assume that persons with the same ability parameters are comparable. That is, the same interpretation applies to persons with identical ability estimates as regards the underlying mental processes triggered by the test. However, research in cognitive psychology shows that persons at the same trait level may…

This study has attempted to investigate the administered written tests in the language department of Islamic Azad University of Hamedan, Iran from validity, practicality and reliability points of view.

Three approaches of validation enquiry were applied on the data obtained from a proficiency test carried out with 3,398 PhD candidates as a partial requirement for entering PhD program in Iran. The data obtained from the reading section were subjected to an exploratory factor analysis (EFA). The EFA yielded nine factors in the reading section.…

The present study was carried out to find out whether regular administration of cloze test improved the students' knowledge of grammar more than the multiple choice one.
