This dissertation comprises three complementary studies that aim to advance the understanding and practice of Individualized Education Programs (IEP) and Present Levels of Academic Achievement and Functional Performance (PLAAFP) development in special education. In the first study, we systematically reviewed empirical research measuring IEP…

Experienced discrimination based on identity and appearance (or discrimination experience) is critical to assess among the college student population given its relationship to six key components of the college student experience. Investigating this variable requires the use of a psychometrically sound scale that demonstrates adequate validity and…

No Child Left Behind (NCLB) cemented a standardized testing assessment culture in the United States but research has highlighted the inequities (Au, 2020; Dixon, 1978; Grodsky et al., 2008; Khan, 2020; Moses & Nanna, 2007), unreliability (Hunt et al., 2010; Pizmony-Levy & Green Saraisky, 2016) and negative impacts (Berryhill et al., 2009;…

This study aimed to provide evidence for the reliability and validity of the "Systems Coaching Survey (SCS)." Systems coaching is an approach to building capacity among groups of educators to drive educational reform efforts by employing seven interdependent sets of skills (interpersonal communication, data-based problem solving, team…

This dissertation investigated predictors of scientific civic engagement among undergraduate students through a multimethod approach, focusing on how educational experiences shaped students' engagement with their communities using scientific skills. This multipart study addressed gaps in understanding how educational practices, identity, and sense…

The emergence of digital-first assessments is prompting reconsideration of, and innovation in, aspects of psychometrics, test validation, and test use. Using the Duolingo English Test (DET) as an example, this three-paper series seeks to address issues concerning the estimation of classification consistency and the reporting of results for such…

The purpose of this mixed-methods research was to develop and validate an instrument to measure teacher self-efficacy for teachers of students with visual impairments (TSVIs). The researcher used a six step process for survey development and validation, which included 1) literature review; 2) a preliminary qualitative study; 3) synthesis of…

Nationally, 76% of school-aged children fail to meet recommendations for 60 minutes of daily physical activity (PA). To increase school-based PA, a comprehensive school physical activity program (CSPAP) is recommended. A CSPAP is a multicomponent, "whole-of-school approach" that includes five components: (a) quality physical education,…

The purpose of this study was to develop a multidimensional College Mental Health Assessment Inventory (CMHAI) specifically for the college student population. In the first phase, a conceptual and theoretical review of general existing scales was performed, followed by conducting exploratory semi-structured interviews with twelve participants.…

The study aimed to elicit information from Vietnamese EFL university instructors about their knowledge and skills regarding the principles, theory, and practices of language assessment by means of revision and validation of the Language Assessment Literacy--Revised Vietnam (LAL-RV), which was previously developed by Kremmel and Harding (2020). A…

The study established the validity and reliability of a weighted individual performance-based assessment tool within the utility scope of middle school orchestral strings. The following research questions guided this study: 1. What specific string-playing behaviors and corresponding criteria validate a weighted individual performance-based…

Concerns surrounding subscore use, which have traditionally been examined in large-scale educational testing programs (e.g., SAT, GRE)--namely, that "information obtained from subscores that seems intuitively useful may not contain additional information over and above the total score" (p. 2)--have been argued to apply equally to…

The Next Generation Science Standards propose a multidimensional model of science learning, comprised of Core Disciplinary Ideas, Science and Engineering Practices, and Crosscutting Concepts (NGSS Lead States, 2013). Accordingly, there is a need for student assessment aligned with the new standards. Creating assessments that validly and reliably…
