Despite the increasing demand for diagnostic information, observed subscores have been often reported to lack adequate psychometric qualities such as reliability, distinctiveness, and validity. Therefore, several statistical techniques based on CTT and IRT frameworks have been proposed to improve the quality of subscores. More recently, DCM has…

Data literacy is crucial for adolescents to access and navigate data in today's technology-driven world. Researchers emphasize the need for K-12 students to attain data literacy. However, few available instructions have incorporated validated assessments. Therefore, I developed and implemented the Data literacy Assessment for Middle graders…

Autism Spectrum Disorder (ASD) is diagnosed using the same criteria for males and females (e.g., DSM-5, ICD-10). Our understanding of ASD, including its etiology, symptom presentation, and prevalence has evolved significantly over time motivating several changes to the diagnostic criteria and the tools with which symptoms are measured. One aspect…

Student Experience surveys are used to measure student attitudes towards their campus as well as to initiate conversations for institutional change. Validity evidence to support the interpretations of these surveys' results, however, is lacking. The first purpose of this study was to compare three Differential Item Functioning (DIF) methods on…

Validity of a measurement refers to appropriate test score meanings, uses, and interpretations (Messick, 1989; Kane, 1992). There are different approaches to validity: an evidentiary aspect of validity is one requiring gathering statistical evidence to evaluate test score meaning. A common approach to validation is comparisons of test score equity…

The present dissertation investigated the impact of scales/scoring methods and prompt linguistic features on the measurement quality of L2 English elicited imitation (EI). Scales/scoring methods are an important feature for the validity and reliability of L2 EI test, but less is known (Yan et al., 2016). Prompt linguistic features are also known…

Existing methods used to validate self-report questionnaires in foreign language teaching effectiveness have relied on Classical Test Theory (CTT). However, the use of CTT approaches limits the reliability and validity of self-report instruments. The Rasch Model, which is based on the principles of objective measurement, addresses some of the…

This study conducted a development and validation of a vignette-based grit scale (Grit-V). The purpose was to determine if the use of vignettes provided more validity evidence than short simple-sentence item endorsements. The data were gathered from a sample population of undergraduate students from The University of Alabama. Focus group data were…

Preparing and supporting teachers to enact teaching practice that responds to diversity, challenges educational inequities, and promotes social justice is a pressing yet daunting and complex task. More research is needed to understand how and to what extent teacher education programs prepare and support teacher candidates to enhance the…

The implementation of the Common Core State Standards (CCSS) has placed increased accountability for outcomes on both students and teachers. To address the current youth literacy crisis in the United States, the CCSS call for students to read increasingly complex informational and literary texts. Since teachers are held accountable for students'…

Students must be sufficiently motivated in order to achieve the intended learning outcomes of their college courses. Research in education and psychology has found motivation to be context-dependent. Therefore, students' motivation is likely to differ from one semester to the next according to which courses students are taking. However, there are…

This study investigated the breakdown effect of a listening comprehension test, whether test takers are affected in comprehending lectures by impediments, and collected test takers' cognitive awareness on test tasks which contain listening breakdown factors how they perceived these impediments. In this context of the study, a "Breakdown" is a test…

The study discussed the importance of test validity, often established when making decisions that may affect a student's future. The decisions made by policymakers and educators must not adversely affect any particular subgroups of students (i.e., year of administration, gender, ethnicity, level English proficiency, socioeconomic status, and…

Little is known about students' perceptions of online enrollment processes. Student satisfaction is part of the assessment required for accreditation, but evidence suggests that college administrators are oriented to retention and graduation rates rather than to consumer perception. The purpose of this descriptive quantitative study was to develop…

Although classroom assessment is one of the most frequent practices carried out by teachers in all educational programs, limited research has been conducted to investigate the dependability and validity of criterion-referenced tests (CRTs). The main purpose of this study is to develop a criterion-referenced test for first-year Japanese university…
