Local item dependency (LID) occurs when test-takers' responses to one test item are affected by their responses to another. It can be problematic if it causes inflated reliability estimates or distorted person and item measures. The cued-recall reading comprehension test in Hu and Nation's (2000) well-known and influential coverage--comprehension…

This three-manuscript dissertation attempts to answer the question: "How does students' English language proficiency (ELP) inform the availability, structure, and use of English language accommodations and intervention to support the academic achievement of English learner (EL) students?" The question is addressed using three independent…

Comparing language tests and test preparation materials holds important implications for the latter's validity and reliability. However, not enough studies compare such materials across a wide range of indices. Therefore, this study investigated the text complexity of IELTS academic reading tests (IRT) and IELTS reading practice tests (IRPrT).…

We explored whether performance differences exist between proficient and poor readers on implicit text information. Next, we explored whether indices of meta-cognitive monitoring predicted reading performance. Finally, we examined whether poor and proficient readers exhibited distinct meta-cognitive profiles with respect to reading comprehension…

Efficiency in reading component skills is crucial for reading comprehension, as efficient subprocesses do not extensively consume limited cognitive resources, making them available for comprehension processes. Cognitive efficiency is typically measured with speeded tests of relatively easy items. Observed responses and response times indicate the…

This study examines the relationships among various major factors that may affect the difficulty level of language tests in an attempt to enhance the robustness of item difficulty estimation, which constitutes a crucial factor ensuring the equivalency of high-stakes tests. The observed difficulties of the reading and listening sections of two EFL…

We examine the effects of computer-based versus paper-based assessment of critical thinking skills, adapted from English (in the U.S.) to Chinese. Using data collected based on a random assignment between the two modes in multiple Chinese colleges, we investigate mode effects from multiple perspectives: mean scores, measurement precision, item…

Repeated viewing of the same video is a common strategy among autonomous language learners as well as a much used pedagogical strategy among foreign language (FL) teachers. Learners may watch the same video more than once, to increase global comprehension of the target language or to focus their attention on linguistic aspects, such as new…

Background: Of the myriad of reading comprehension (RC) assessments used in schools, multiple-choice (MC) questions continue to be one of the most prevalent formats used by educators and researchers. Outcomes from RC assessments dictate many critical factors encountered during a student's academic career, and it is crucial that we gain a deeper…

The objectives of this study are to see if Reciprocal Teaching (RT) is more a effective Language Learning Strategy (LLS) to teach reading comprehension, and to see if students of high reading comprehension achievement have better reading comprehension than those of moderate and low reading comprehension achievement. The 3 x 2 factorial design is…

Reading comprehension tests are often assumed to measure the same, or at least similar, constructs. Yet, reading is not a single but a multidimensional form of processing, which means that variations in terms of reading material and item design may emphasize one aspect of the construct at the cost of another. The educational systems in Denmark,…

The purpose of the present study is to apply the item response theory (IRT) and testlet response theory (TRT) models to a reading comprehension test. This study applied the TRT models and the traditional IRT model to a seventh-grade reading comprehension test (n = 8,815) with eight testlets. These three models were compared to determine the best…

This study aims to investigate patterns of variation in the interplay of L2 language ability and general reading comprehension skills in L2 reading, by comparing item-level effects of test-takers' results on L1 and L2 reading comprehension tests. The material comes from more than 500,000 people tested on L1 (Swedish) and L2 (English) in the…

In many reading comprehension tests, different test formats are employed. Two commonly used test formats to measure reading comprehension are sustained passages followed by some questions and cloze items. Individual differences in handling test format peculiarities could constitute a source of score variance. In this study, a bifactor Rasch model…

We analyzed a pool of items from an admissions test for differential item functioning (DIF) for groups based on age, socioeconomic status, citizenship, or English language status using Mantel-Haenszel and item response theory. DIF items were systematically examined to identify its possible sources by item type, content, and wording. DIF was…
