Cognitive diagnostic models (CDMs) have received much interest within the field of language testing over the last decade due to their great potential to provide diagnostic feedback to all stakeholders and ultimately improve language teaching and learning. A large number of studies have demonstrated the application of CDMs on advanced large-scale…

The current study aims to explore the cognitive validity of the iBT TOEFL reading test by investigating test takers' eye movements on individual items. It is assumed that successful test takers would adopt the intended reading processes, the same types and levels of cognitive processes that they would use for real-world reading tasks. Forty-seven…

Score interchangeability of Computerized Fixed-Length Linear Testing (henceforth CFLT) and Paper-and-Pencil-Based Testing (henceforth PPBT) has become a controversial issue over the last decade when technology has meaningfully restructured methods of the educational assessment. Given this controversy, various testing guidelines published on…

The central purpose of this paper is to examine validity problems arising from the multiple-choice items and technical passages in the Test of English as a Foreign Language Internet-based Test (TOEFL iBT) reading section, primarily concentrating on construct-irrelevant variance (Messick, 1989). My personal TOEFL iBT experience, along with my…

This study had two aims. The first was to explain the process of using the Rasch measurement model to validate tests in an easy-to-understand way for those unfamiliar with the Rasch measurement model. The second was to validate two final exams with several shared items. The exams were given to two groups of students with slightly differing English…

Despite calls for engaging assessments targeting young language learners (YLLs) between 8 and 13 years old, what makes assessment tasks engaging and how such task characteristics affect measurement quality have not been well studied empirically. Furthermore, there has been a dearth of validity research about technology-enhanced speaking tests for…

The study investigated the criterion-related validity of the "Test of English as a Foreign Language"[TM] Internet-based test (TOEFL[R] iBT) Listening section by examining its relationship to a criterion measure designed to reflect language-use tasks that university students encounter in everyday academic life: listening to academic…

The assumption called PIRC (proportional item response curve) was tested in which PIRC was used to predict item scores of selected examinees on selected items. Findings show approximate accuracies of prediction for PIRC, the three-parameter logist model, and a modified Rasch model. (12 references) (Author/LB)

One way of determining construct validity of vocabulary items in language tests is to interview subjects directly after taking the items to ascertain what is known about the target words in question. This approach was combined within the framework of lexical competency in a study of the behavior of lexical items on the Test of English as a Foreign…

The Test of English as a Foreign Language (TOEFL) program is exploring a change in Section 3 of the TOEFL test that would replace the vocabulary subpart with additional reading comprehension questions. This study investigated the proposed revision in terms of the length and timing that would be necessary to address concerns of test speededness of…

This study was undertaken to test the hypothesis that items of the Test of English as a Foreign Language (TOEFL) containing reference to American people, places, customs, etc., tend to favor examinees who have spent some time living in the United States. Two samples of examinees were drawn from the March 1987 TOEFL administration, one tested in…

This paper traces developments in educational psychology and measurement that led to the Test of English as a Foreign Language (TOEFL) and the test of English for International Communication (TOEIC) and the application of educational measurement terms such as validity and reliability to testing. Use of a table of specifications for planning…
