The development and evaluation of valid assessments of scientific reasoning are an integral part of research in science education. In the present study, we used the linear logistic test model (LLTM) to analyze how item features related to text complexity and the presence of visual representations influence the overall item difficulty of an…

To better understand Tennessee's new standardized science assessments, this quantitative study utilized a nonexperimental, descriptive-comparative design to compare the readability of the long-used science TCAP assessment with the newly created science TNReady assessment in grades three, four, and five. As new standards in the state boast higher…

The following is a five-chapter dissertation surrounding the use of text mining techniques for better understanding the language of mathematics items from standardized tests to improve linguistic equity of these items to support assessment of English Language Learners. Introduction: The dissertation begins with an overview of the problem that…

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).…

In this study, the author examined potential mediators of the negative relationship between the absolute difference in items' lengths and their inter-item correlation size. Fifty-two randomly ordered items from five personality scales were administered to 622 university students, and 46 respondents from a survey website rated the items'…

Progress monitoring has been adopted as an integral part of multi-tiered support systems. Oral reading fluency (ORF) is the most established assessment for progress-monitoring purposes. To generate valid trend lines or slopes, ORF passages must be of equivalent difficulty. Recently, however, evidence indicates that ORF passages are not equivalent,…

Language is frequently discussed as barrier to mathematics word problems. Hence this paper presents the initial findings of a linguistic analysis of numeracy skills test sample items. The theoretical perspective of multi-modal text analysis underpinned this study, in which data was extracted from the ten sample numeracy test items released by the…

Background: We compared responsiveness to two self-report assessments of loneliness: the "UCLA Loneliness Scale" (UCLALS) designed for the general community, and the "Modified Worker Loneliness Questionnaire" (MWLQ) designed for people with intellectual disability (ID). Methods: Participants were 56 older adults with…

This dissertation investigates and problematizes emergent bilingual students' achievement gaps in an existing corpus of middle-school science assessment data. I first characterize achievement gaps across national data, state data, and the corpus of approximately 27,000 students as an analytic backdrop. I then sample a subset of the 6th grade…

This study presents the processes of developing and establishing reliability and validity of a reading test by administering an integrative approach as conventional reliability and validity measures superficially reveals the difficulty of a reading test. In this respect, analysing vocabulary frequency of the test is regarded as a more eligible way…

The research described in this report is a randomized controlled trial in which seventh- and eighth-grade students were randomly assigned to complete a set of 25 math questions delivered with either standard language or language that had undergone "linguistic modification" by the research team. The purpose of the study was to assess the…

Test validity issues considered by test developers and school districts rarely include individual item readability levels. In this study, items from a major standardized test were examined for individual item readability level and item difficulty. The Homan-Hewitt Readability Formula was applied to items across three grade levels. Results of…

To estimate reading difficulty of items on a sentence repetition task, a study had 50 adult English as a second language (ESL) students repeat each of 26 sentences immediately after two presentations. High-difficulty items were derivationally more complex than low-difficulty items, and the most difficult items involved the processing of…

Reading selections from six Scholastic Aptitude Tests (SAT) administered from 1947 to 1975 were analyzed to determine whether a decrease in the difficulty level of elementary and secondary textbooks, workbooks, and teachers' guides corresponded with the SAT score decline. Various indices of reading difficulty and challenge were used. Readability…
