A common practical challenge is how to assign ability estimates to all incorrect and all correct response patterns when using item response theory (IRT) models and maximum likelihood estimation (MLE) since ability estimates for these types of responses equal -8 or +8. This article uses a simulation study and data from an operational K-12…

Purpose: This study explores the roles of morphological skills (Morphological Awareness, Morphological-Syntactic-Knowledge,Morphological-Semantic-Knowledge, and Morphological-Orthographic/Phonological-Knowledge), vocabulary (knowledge of definitions, relationships between words, and polysemous meanings), and syntax in contributing to adolescent…

Many low-stakes assessments, such as international large-scale surveys, are administered during time-limited testing sessions and some test-takers are not able to endorse the last items of the test, resulting in not-reached (NR) items. However, because the test has no consequence for the respondents, these NR items can also stem from quitting the…

Recent research has proven the importance of non-cognitive determinants, such as motivation and resilience, in improving reading achievement. This study provides insights on how these two determinants are displayed by students living in contexts of high social vulnerability. A mixed methodology was used to conduct the study in six schools across…

There have been numerous recent calls in literacy research and teacher education to disrupt the 'struggling reader' label, but a dearth of empirical studies on the topic. This qualitative analysis explores the complex issues preservice teachers (PSTs) faced as they examined young readers' sense-making through a reading assessment assignment. Our…

Purpose: There are extensive concerns about the size of speech-language caseloads in schools. However, little empirical data exist regarding the patterns of speech-language services enrollment. We reviewed data from several hundred schools in a large state to explore the role of school-level factors in speech-language case enrollment. Method:…

In education research, statistical significance and effect size are 2 sides of 1 coin; they complement each other but they do not substitute for each other. This descriptive study, however, was limited to effect size only because years of experience with Idaho statewide student samples of up to 24,000 the rare outcomes has been t-tests with…

In educational and psychological assessments, attending to item response process can be useful in understanding and improving the validity of measurement. This dissertation consists of three studies each of which proposes and applies item response theory (IRT) methods for modeling and understanding cognitive/psychological response process in…

Standardized reading assessments are often used as an admissions criterion for college admittance, however, the relationship and predictive validity of reading assessments to academic achievement remains in question. Through a quantitative review of the literature, we conducted a meta-analysis to examine how well performance on college reading…

Reading comprehension assessments are used for postsecondary course placement and advising, and they are components of college entrance exams. Therefore, a quantitative understanding of the relationship between reading comprehension assessments and postsecondary academic achievement is needed. To address this need, we conducted a meta-analysis to…

The Content Proximity Project was designed to improve the content validity of the MAP® Growth™ assessments while retaining the ability for the test to adapt off-grade and meet students wherever they are in their learning. Two main features of the project were the development of an enhanced item selection algorithm, and a spring pilot study…

Although there is an abundance of research on the association of school poverty (or socioeconomic status) and test score level, there is very little rigorous longitudinal evidence on the cumulative effects of exposure to differing school contexts. Drawing from methods used first in epidemiology and then in neighborhood effects research, we use…

This meta-analysis included experimental or quasi-experimental intervention studies conducted between 1980 and 2020 that aimed to improve reading outcomes for Grade K-5 students with or at risk for dyslexia (i.e., students with or at risk for word reading difficulties, defined as scoring at or below norm-referenced screening or mean baseline…

Vocabulary knowledge is one of the most important elements of reading comprehension. Text coverage is the proportion of known words in a given text. We hypothesize that text comprehension increases exponentially with text coverage due to network effects and activation of prior knowledge. In addition, the lexical threshold hypothesis states that…

Despite a growing focus on access to and use of emergent literacy assessment in early childhood, little is known about early childhood teachers' data practices and their associations with children's emergent literacy skills. A questionnaire was used to confirm and elaborate findings from prior qualitative work (Schachter & Piasta, 2022)…
